Professional Cat Urine Odor Removal Service
OdorXpert provides professional cat urine odor removal for homes where the contamination has soaked past the surface and into the structure — into subfloors, concrete slabs, drywall, wall studs, baseboards, wood framing, and joists.
Our services always start with a Pet Odor Inspection: we show you what and where the damages are, using electronic moisture readings to find wet urine deposits, UV black light to locate stains, and expert odor mapping. You get a detailed report and itemized estimate to get rid of cat urine odor for good.
We are not a carpet cleaning service. Most of our jobs start with carpet removal. We remove urine-damaged materials — baseboards, drywall, insulation, laminate, vinyl, and tile — to access the contaminated structure underneath, dry it out, sand as needed, and seal it permanently with our odor encapsulation system.
Our technicians are highly trained to get cat urine odor out of concrete, subfloors, wall studs, joists, bricks, tile, crawlspaces, attics, and more — and we back our Odor Encapsulator Treatment with a 5-year guarantee.
With over 35 years of experience in odor remediation, we may not always be the first company you call — but we’ll be the last call you ever need to make.
Contractors specialize in rebuilding. Flooring installers specialize in flooring. We specialize exclusively in odor removal — dog, cat, rodent, and human urine. If it doesn’t stink, there’s no reason to call us. We get rid of the odor so your contractor can put the house back together on a clean, odor-free surface — and so your flooring installer can lay new flooring over odor-free concrete or subfloors.

Backed by a 5-Year Guarantee — Because We Treat the Source, Not the Symptom
Every completed project is backed by our 5-year guarantee. If we inspect, access, treat, and seal your home according to our standards and the odor returns, we come back at no additional charge and correct the problem. No questions. No excuses.
Most cleaning companies, carpet cleaners, and air treatment providers don’t offer any guarantee on odor removal. Ask them. The answer tells you everything you need to know about whether they’re treating the source or just hoping it works.
Our guarantee isn’t a marketing gimmick. It’s possible because our process actually eliminates contamination at the structural level. Think of it like killing weeds. If you cut a weed at the surface, it looks gone — but the root is still there, and it grows back. That’s what surface cleaning does to cat urine odor. When you eliminate the problem at the root, it’s gone for good. When you only treat the surface, it’s just a matter of time before you smell it again.
Before you hire anyone for cat urine odor removal, ask one question: “What’s your guarantee?” If they hesitate, you have your answer.
Remove Cat Urine Smell From House… Permanently!
If any of these sound familiar, your cat urine problem has gone structural — and you need more than cleaning:
- Embarrassing cat urine smell in your home — guests won’t visit, contractors refuse to work inside, and you can’t live like this anymore
- Garage smells like cat urine — it was used as a cat habitat for years and nothing you’ve tried eliminates the litter box smell
- Bought a house that smells like cat pee — you inherited or purchased a home with severe urine damage and didn’t realize the extent until you moved in
- Cat urine smell after remodel — you bought a remodeled or flipped home that now smells like cat urine everywhere because the seller covered it up with cosmetic updates
- Can’t sell your home because of cat urine odor — buyers walk through the door and immediately walk out
- Cat urine smell keeps coming back — no matter what products you use, the odor returns within days or weeks
- Cat urine smell worse in summer or humidity — tolerable in winter, unbearable when it’s hot
- Cat urine smell after removing carpet — you pulled up the carpet but the odor is still there because it’s in the subfloor or concrete underneath
- Tried everything for cat urine odor — cleaning products, ozone treatments, air purifiers — none of them fixed it
The odor is in the structure — not on the surface. Cleaning treats the top. We treat what’s underneath.
Every week we get calls from homeowners who hired a cheaper service first. The carpet cleaner came. The ozone machine ran for three days. The handyman painted primer on the subfloor. None of it worked. Now they’ve spent money, lost time, and the smell is still there — sometimes worse than before because the cleaning spread the contamination deeper.
The cheapest option isn’t the one with the lowest price. It’s the one that works the first time. Doing it wrong twice always costs more than doing it right once. And if your contractor said he can handle the odor — you were smart enough to find this page before letting him install new materials over a problem that isn’t solved. Don’t let anyone put your home back together until you know for certain the odor is gone.

What We Fix: Cat Urine Odor in Structural Materials
Our professional cat urine odor removal service addresses contamination that cleaning companies, carpet cleaners, and air treatment services cannot reach:
- Subfloors (plywood and OSB) — the #1 source in severe cases. Urine soaks through carpet and pad and saturates the wood at perimeter edges and tack strip lines.
- Concrete slabs — urine penetrates concrete and off-gasses indefinitely without treatment and encapsulation.
- Drywall — cats spray walls, and urine wicks up from the floor. The bottom inches to feet of drywall absorb contamination that paint cannot seal.
- Wall studs, framing, and joists — in severe cases, urine penetrates through drywall into bottom plates, studs, joists, and structural wood.
- Baseboards and trim — swollen or discolored baseboards are hiding contamination behind them at the subfloor-wall junction.
- Door jambs and thresholds — cats mark doorways. Urine collects at corners and saturates the wood framing.
- Tile and grout — urine penetrates grout lines and the substrate beneath tile.
- Concrete garage floors — garages used as cat habitats develop deep contamination in the slab.
- Crawlspaces and attics — contamination can reach these areas in severe multi-cat homes.
- Kitchen cabinets, doors, window frames, backsplash — in severe cases, these built-in elements absorb urine and contribute to whole-house odor.
We don’t use enzymes, fragrances, or any of the typical products you’ll read about online. In many cases, we’re dealing with multiple years of cat damage — there are no miracle ointments or fancy-named products that fix that. What fixes it is skilled technicians, hard work, and dedication to our craft. We remove the urine-damaged carpet, and the urine-damaged drywall, and the contaminated baseboards, and any other material that’s absorbed the contamination — to get to the source of the odor. Then we dry it, prep it, and seal it permanently with our odor encapsulator.
When we pull up new carpet and find shellac painted on the subfloor underneath — or pull up new LVP and find odor-blocking primer on the concrete that didn’t work — we remove those failed coatings and apply our proven, guaranteed odor encapsulator the right way.

Already Tried Another Company or DIY? You're Not Alone.
Most of our clients don’t call us first. They call us after the first attempt failed. After the carpet cleaner came and the smell returned in a week. After the ozone machine ran for days and nothing changed. After they poured gallons of enzyme cleaner into the subfloor. After a contractor painted primer over wet, contaminated wood and it bled through within a month.
This is extremely common — and it’s nothing to be embarrassed about. The problem is that most services aren’t designed for structural contamination. They’re designed for surface cleaning. When you apply a surface solution to a structural problem, it fails. It’s not your fault for trying. It’s the wrong tool for the job.
But here’s what we want you to think about carefully: if it didn’t work the first time, why would doing the same thing again produce a different result? A different enzyme brand won’t reach deeper into the subfloor. A different carpet cleaner still can’t access the drywall behind the baseboard. Another ozone treatment still can’t seal uric acid crystals embedded in concrete.
The reason the odor keeps coming back isn’t that you haven’t found the right product. It’s that no product can reach where the contamination actually is. The only way to eliminate it is to remove the unsalvageable contaminated materials, dry the structural surfaces, prep them, and seal them at the source. That’s what we do. That’s all we do. And we guarantee it for 5 years.

How Severe Is Your Cat Urine Problem?
Not every job is the same. Below, we break down structural cat urine contamination by severity — starting with the most extreme cases — so you can identify where your home falls and what it actually needs.
If your odor is surface-level — a carpet stain, a spot on hardwood, a recent accident on tile — see our pages on carpet odor removal, hardwood floor odor removal, cat spray odor removal, or our blog on cleaning incidental pet urine. But keep reading — even low odor levels can hide severe structural damage underneath.
Severity Level 9–10: Severe Structural Remediation
Scope: Major structural remediation. In worst cases, the dwelling may need to be taken down to the studs. Concrete treatment and sealing. Subfloor remediation. Full odor encapsulation of all structural surfaces. Rebuild handled by your contractor.
What This Looks Like
You smell cat urine before you open the front door. Inside, every room is affected. Walls, floors, ceilings. This is typically a home where multiple cats lived for years with little or no cleanup. Litter boxes overflowed. Cats sprayed every wall. Urine pooled on floors and soaked through to the subfloor, concrete slab, and wall framing.
At this level, you’re also seeing severe damage to kitchen cabinets, doors, window frames, backsplash, and other built-in elements. These materials have absorbed urine and are contributing to the whole-house odor.
Common scenarios: inherited properties, foreclosures, hoarding situations, extreme tenant damage, or homes where a garage or room served as a full-time cat habitat for years.
The Extreme 10+ Scenario: When Contractors Call Us
It’s not uncommon for us to get called by contractors who have already taken the interior down to the studs and concrete — and realized the odor level is not much different than it was before the demolition. They call us. We come in, prep the concrete and remaining studs and framing members, and seal everything with our Odor Encapsulator. These are extreme cases that go beyond a 10. They’re rare, but we get them.
The amazing thing: even in these extreme situations, we’ve been able to eliminate all of the odor so the house could be put back together with no worries of odors returning.
Condos and Apartments at Level 9–10
In condos and multi-unit buildings, Level 9–10 contamination creates a unique problem: the odor permeates into common areas outside the unit and into neighboring units — through shared walls, ceilings, and floors. Neighbors above, below, and beside the affected unit can smell it. HOAs and property managers face complaints.
This requires remediation of the affected unit and inspection of adjacent areas. The good news: we can usually eliminate the odor on the offending side, which stops the migration into common areas and neighboring units.
What the Home Needs
- All flooring, carpet, pad, laminate, vinyl, and tile removed throughout the home
- Drywall removal floor to ceiling, including ceilings where contamination wicked upward
- Subfloor remediation — dried, sanded, sealed where salvageable, replaced where structurally compromised
- Concrete slab treatment and sealing
- Framing inspection — bottom plates, studs, joists, and structural wood dried, sanded, and sealed with our odor encapsulator as needed
- All baseboards, door jambs, thresholds, and trim removed and discarded
- Damaged kitchen cabinets, doors, window frames, and backsplash removed
- Professional drying equipment to pull wet urine and moisture out of subfloor, concrete, and framing
- Sanding off failed primer and shellac from prior DIY attempts
- Full odor encapsulation sealing on all exposed structural surfaces
This is structural remediation. Every contaminated material is accessed, dried, prepped, and sealed with our odor encapsulator. Once we’re done, your contractor can rebuild on a clean, odor-free structure. Your flooring installer can lay new flooring over odor-free concrete or subfloors. Done right, by us, the first time.
Dealing with Level 9–10 Contamination? Give us a call to discuss your situation before scheduling an inspection. If you’re about to purchase a home with severe odor, schedule a pet odor inspection before you buy — know what you’re getting into before you close.

Severity Level 7–8: Significant Cat Urine Odor Remediation
Scope: 4–8 feet of drywall removal from the floor up. Subfloor treatment and sealing. Baseboard and trim replacement. Nearly all rooms affected.
What This Looks Like
You smell it walking in the front door. Visitors notice immediately. The odor can be smelled throughout the house, though some areas may be stronger than others. Strongest along walls, corners, and baseboards. Worse on warm or humid days. Multiple rooms affected. Baseboards are swollen or discolored. When removed, the drywall behind them is soft, stained, or crumbling at the bottom edge.
At this level, you may also see damage to built-in elements — lower kitchen cabinets, door frames, closet shelving, and other materials that have absorbed urine over time.
What the Home Needs
- All flooring, carpet, pad, and tack strip removed in affected rooms
- Drywall cut and removed 4–8 feet up from the floor
- Baseboards, door jambs, and trim removed and discarded
- Professional drying to pull moisture from subfloor, concrete, and framing
- Failed primer and shellac coatings sanded off
- Subfloor and framing dried, sanded, and sealed with our odor encapsulator
- Damaged cabinets, door frames, and built-in elements assessed and removed where contaminated
Once our work is complete, your contractor can install new drywall, baseboards, and trim on a clean, odor-free structure. We get the house ready — they put it back together.
The problem isn’t the carpet — it’s what’s below it. And behind the baseboards. And inside the walls.
Odor in Multiple Rooms? Worse When the House Is Closed Up? You’re Likely at Level 7–8.
Schedule a pet odor inspection to confirm. Call 877-386-3677.
Severity Level 5–6: Targeted Structural Remediation
Scope: 2–4 feet of drywall removal. Specific rooms or throughout the house. Subfloor sealing. Baseboard replacement in affected areas.
What This Looks Like
Persistent smell in certain rooms or hallways, especially when the house is closed up. Not overwhelming but won’t go away. Stronger near certain walls, in closets, litter box areas, or isolated rooms where cats spent the most time.
What the Home Needs
- Flooring removed in affected rooms
- Drywall cut 2–4 feet up in rooms with confirmed spray damage or wicking
- Baseboards removed and replaced by your handyman or contractor
- Drying equipment to pull moisture from subfloor and framing
- Surface residues and failed coatings removed
- Subfloor and exposed framing sealed with our odor encapsulator
Targeted work. You’re not gutting the entire house — you’re addressing the specific areas where contamination penetrated building materials. Same result: source sealed, odor permanently eliminated. Your contractor handles the rebuild.
Persistent Odor in Certain Rooms? Let’s Find Out What’s Behind the Walls.
Call 877-386-3677 to schedule a pet odor inspection.
Severity Level 4: Subfloor and Baseboard Remediation
Scope: Limited drywall removal. Subfloor sealing at perimeter edges. Baseboard removal and replacement by your handyman or contractor.
What This Looks Like
Smell near baseboards, in a corner, or in a specific room. Not filling the house, but persistent. Comes back every time you think it’s fixed. Worse in warm weather.
What the Home Needs
- Carpet and pad removed in affected areas
- Baseboards removed to access subfloor-wall junction
- Limited drywall removal where contamination is confirmed at the base
- Drying equipment to pull moisture from subfloor
- Failed coatings sanded off
- Subfloor sealed with our odor encapsulator at perimeter edges and contaminated areas
- Baseboards replaced by your handyman or contractor where damaged
For certain surfaces like concrete, tile, or vinyl/LVP at this level, our 24–48 hour oxidizing treatment may be the right approach — penetrating the surface to neutralize contamination without demolition, sanding, or sealing, or as an alternative where sealing is not applicable.
Not Sure How Deep It Goes? An Inspection Takes the Guesswork Out.
Odor Level 1–3? Don't Assume It's Just Surface-Level
A low odor level doesn’t always mean a small problem. We’ve walked into homes rated 1–3 on a first impression — the smell is mild, maybe barely noticeable — and found severe structural damage hiding underneath.
Here’s how that happens:
The house was cleaned, deodorized, or renovated, and the odor is being masked or suppressed. It smells OK during a quick walkthrough. But once the inspection is complete, it reveals serious urine damage underneath those clean surfaces. We remove the carpet and find the entire subfloor painted with several coats of primer or shellac. We pull up new LVP and find odor-blocking primer on the concrete that only worked long enough to get the house sold. What looked like a Level 2 problem turns out to be a full or partial gut job because the seller — or their contractor — did not remediate the home properly.
Common situations:
- The house was remodeled — new carpet, new flooring, new kitchens, new bathrooms, new doors, new windows. Looks brand new. But the seller or flipper never addressed the structural contamination. The cosmetic updates covered it up.
- A contractor did the remediation and failed — missed contaminated areas, didn’t access the subfloor, or used DIY tricks from YouTube that didn’t work.
- The home was owned by a hoarder — the property was cleaned out and cleaned up, but nobody addressed the urine damage in the structure.
- The neighborhood cat lady lived there for decades — the home changed hands and the new owner is discovering the extent of the hidden damage.
- Disclosure issues and buyer/seller disputes — the seller said the odor was resolved, but it wasn’t. Now you own a home with a structural contamination problem that was covered up, not fixed.
- Seller hired a company to blast the home with ozone, hydroxyl, chlorine dioxide gas, or foggers — these systems treat the air temporarily but are useless on severe structural odor damage. Once the equipment is gone, the smell comes right back.
- Open house had every door and window open, with potpourri, candles, and plug-ins throughout the house — and nothing on the seller’s disclosure questionnaire mentioned pet damage. Classic red flag.
This is exactly why we start every job with a pet odor inspection. We don’t go by how the house smells on a walkthrough. We use UV black light, moisture meters, and expert assessment to find what’s hiding behind new surfaces, under new flooring, and inside walls. The odor level you smell on day one may not reflect the severity of the damage.

Why Cat Urine Odor Keeps Coming Back
The most common frustration: “I’ve done everything and the smell keeps coming back.”
Urine Crystallization
Deep Absorption
Heat and Humidity Reactivation
Moisture interacts with uric acid crystals, causing off-gassing. Manageable in winter, unbearable in summer — but the contamination never left. It’s always there, waiting for the right conditions.
Liquid Cleaning Spreads It Deeper
Liquid products like enzymes, deodorizers, vinegar, and store-bought cleaners actually spread urine deeper into the subfloor and outward into drywall and baseboards. Every time liquid is poured on a contaminated surface, it migrates through seams, under edges, and into adjacent materials. Mopping floors and cleaning walls is especially bad — it can take a one-room problem and spread it into three rooms over time.
Cleaning treats the top. We treat what’s underneath. That’s why our results are permanent.
The Smell Keeps Coming Back Because the Source Was Never Treated.
Call 877-386-3677 to schedule an inspection.
What Doesn't Work on Severe Cat Urine Contamination
DIY Remedies: Enzyme Cleaners, Vinegar, Baking Soda, Odor-Blocking Primers, Shellac
These products have a place. Used properly on the right surface within a few days — or sometimes a few weeks — of an accident, they can produce satisfactory results for fresh, isolated incidents. If you’re cleaning up after your own pet right away, these are the right tools. See our blog post on DIY cleaning for fresh pet accidents.
But when it comes to severe urine odor, it’s a different story. Most of our clients have already used one or more of these products — enzymes, vinegar, baking soda, bleach — before they call us. We see the firsthand results: the additional damage caused by all that liquid being poured into already-contaminated materials. We end up removing urine-soaked drywall, baseboards, and even hardwood floors to get to the source where the odor has spread because of repeated wet cleaning.
Pouring more liquid doesn’t help — it adds moisture and spreads the problem further. Odor-blocking primers and shellac can fail too, because the surface was never properly dried or prepped before they were applied. We regularly sand off these failed coatings before applying our encapsulator the right way.
Professional Air Treatments: Ozone, Hydroxyl Generators, Chlorine Dioxide
Legitimate professional services that treat the air — not the materials. Temporary results. When the equipment turns off, contaminated materials off-gas again. The source was never treated. We don’t offer these because they don’t solve the problem at the structural level.
Carpet Cleaning
Carpet cleaners are great at what they do. They clean carpet. Many of them are very good at removing spots and minimizing odor too — and if your problem is a fresh accident from your own pet, that’s exactly who you should call.
But our clients are usually on the other end of the spectrum. They’re embarrassed to have guests over because the house smells. They want new carpet but don’t want the old urine odor in the subfloor coming through it. They’ve already had carpet cleaned multiple times and the smell still comes back. That’s because the odor isn’t in the carpet — it’s in the subfloor, baseboard, and drywall behind it. Cleaning the carpet is treating the wrong material entirely.
Replacing Carpet or Remodeling Without Treating the Structure
The most common mistake. New flooring over a saturated subfloor traps contamination and forces off-gassing through seams. Cosmetic remodels — paint, baseboards, trim — look updated but the contamination is still behind and beneath every new surface.
Already Tried Everything? That’s Exactly Why We Exist.
We treat the structure — not the surface. Call 877-386-3677.

Why Most Companies Can't Fix Severe Cat Urine Odor
There are a lot of companies using the keyword “pet odor removal service.” What most of them actually provide is enzymes, deodorizers, and plug-in devices like ozone or hydroxyl generators. There’s nothing wrong with using these services for the right situation. We sometimes even encourage clients to try them first — so when they call us, they have no doubt they’re calling the right people to get it done right.
One client called us back after using two or three other services and referred to our work as “the nuclear option.” She said she was hoping she didn’t have to use us because of the measures we needed to take to get her home odor-free. She also said she should have just called us first.
We don’t come in with spray bottles, perfumes, and easy wipes. We come in with demo tools, sanders, grinders, and professional drying equipment. Our jobs run anywhere from one day to two or three weeks depending on the amount of damage. But when we’re finished, you’d never know there was a cat in the house.
Cleaning companies clean surfaces. Air treatment companies treat air. They don’t open walls. They don’t access subfloors. They don’t have drying equipment to pull wet urine out of structural materials. They don’t seal contaminated framing with professional-grade odor encapsulators.
If you can’t reach the source, you can’t fix the problem.
We open walls. We pull up floors. We remove damaged drywall and baseboards. We deploy professional drying equipment to extract moisture and wet urine from subfloors, concrete, and framing members. We sand off failed primers and shellac. And once materials are clean, dry, and properly prepped, we apply our odor encapsulator — a professional-grade barrier coating that stops off-gassing permanently. Applied by professionals with over 35 years of experience.
We don’t come to your home to see if we can get rid of the odor. We tell you how we’re going to do it before we even start the job. We produce results, not excuses.
Done right, by us, the first time.
Think about it this way: you can spend $500 on a service that doesn’t work, then another $800 on a different service that also doesn’t work, then call us. Or you can call us now. Either way, we’re the ones who fix it. The only question is how much time and money you spend before you get here.
We May Not Be the First Company You Call — But We’ll Be the Last.

How to Find the Right Company for Severe Urine Odor Removal
If you’re calling around for quotes, here’s the single best question you can ask:
“What’s your guarantee?”
The longer the guarantee, the more confident the company is in their own ability to actually solve the problem. A short guarantee — or no guarantee at all — tells you they don’t expect their work to last. Most cleaning companies, carpet cleaners, and ozone providers don’t offer one because they know the odor is going to come back.
We offer a 5-year guarantee that is unmatched in the urine odor removal industry. That’s how confident we are in our process and our odor encapsulator system.
Another vetting question: what do they specialize in? Most “odor removal” companies handle everything — smoke, mold, mildew, garbage, dead animal, pet odor. We’re one of the few services that specialize exclusively in dog, cat, rodent, and human urine odor removal. If it doesn’t stink from urine, there’s no reason to call us. That’s our entire focus.
Our Cat Urine Odor Removal Process
Every job follows a documented process. No guessing. No shortcuts.
Step 1: Pet Odor Inspection and Documentation
UV black light inspection, moisture meters, hands-on assessment. We find the urine-stained areas, rate severity, document with photos, and provide a detailed report with itemized estimate before work begins. Part of remediation is knowing what’s salvageable and what’s not — and being able to explain the procedure so you understand exactly what it takes to eliminate the odor 100%.
Step 2: Remove Damaged Materials and Access the Source
We remove carpet, pad, tack strip, urine-damaged baseboards, and contaminated drywall. We don’t just remove carpet — we remove every superficial material that absorbed urine to get to the actual source. In many cases, we find shellac under carpet or odor-blocking primer under new flooring from prior failed attempts. We remove all failed surface coatings so we have a clean slate to work with.
Step 3: Dry the Structure
We deploy professional drying equipment to pull wet urine and residual moisture out of the subfloor, concrete, and framing members. Years of enzyme treatments, vinegar, and wet cleaning products have saturated these materials. We monitor with moisture meters and do not proceed until everything is confirmed dry.
Step 4: Prep and Clean
Sand off failed primer and shellac coatings. Clean concrete. Remove surface residues. For concrete, tile, or vinyl surfaces, we may apply our 24–48 hour oxidizing treatment to neutralize contamination before encapsulation.
Step 5: Seal with Our Odor Encapsulator
Our specialized odor encapsulation system goes on every contaminated surface. Not primer. Not paint. A professional-grade barrier that stops off-gassing permanently. Applied by professionals with over 35 years of experience.
Step 6: Hand Off to Your Contractor and Flooring Installer
Once sealing is verified and the odor is confirmed gone, your contractor can install new drywall, baseboards, and trim on a clean, odor-free structure. Your flooring installer can lay new flooring over odor-free subfloors and concrete. We handle the odor. They handle the rebuild. That’s why our results last — and why we offer a 5-year guarantee.
Our Process Works. Every Time. Done Right the First Time.
Call 877-386-3677 to get started.

We treat the structure. We remove damaged materials, access contaminated subfloors, concrete, drywall, and framing. We dry them with professional equipment. We prep them. We seal them with our odor encapsulation system. And we back it with a 5-year guarantee.
If we inspect, access, treat, and seal according to our standards and the odor returns, we make it right. We come back at no additional charge and correct the problem. Ask any carpet cleaner, cleaning company, or ozone provider what their guarantee is. Most don’t have one. That tells you everything.
Common Situations That Lead to Our Cat Urine Odor Removal Service
Bought a Home That Smells Like Cat Urine
The seller covered it up with cosmetic updates. You moved in, closed the windows, and the odor came flooding back. The contamination is in the subfloor, concrete, and drywall behind those new surfaces. Get a pet odor inspection before closing — or call us now if you already own it. Learn more about urine damage in a house for sale.
Bought a Remodeled Home That Now Smells Like Cat Urine
The flip looked great. But within days of closing up the house, the smell is everywhere. New flooring was installed over a saturated subfloor. New paint covered contaminated drywall. The remodel was cosmetic. The contamination is structural. Now the new materials have to come up to reach the source.
Inherited a Home with Severe Cat Urine Damage
A relative passed away and left a home where multiple cats lived for years. Overwhelming. You’ve tried cleaning products and air treatments. Nothing works. The home needs structural assessment and systematic remediation so it can be sold, rented, or occupied.
Selling a Home with Cat Urine Damage
Buyers walk through and leave. Interested buyers negotiate hard after inspection. Remediating before listing protects your asking price, reduces time on market, and removes the biggest objection buyers have. Learn more about urine damage in a house for sale.
Garage Used as a Cat Habitat for Years
Concrete floor saturated. Drywall destroyed along the bottom. Framing has absorbed urine. Standard cleaning doesn’t touch this. The concrete needs treatment and encapsulation, damaged drywall and baseboards need removal, framing needs drying, prepping, and sealing. See our garage odor removal service.
Whole House Smells Like Cat Urine After Removing Carpet
You pulled up carpet expecting the smell to leave. The subfloor is stained and saturated. The odor is stronger than before because the carpet was containing the off-gassing. The fix: access, dry, prep, and seal the subfloor with our odor encapsulator before your flooring installer lays new flooring.
Cat Urine Smell Won't Go Away
You’ve tried every product and service. Nothing works because nothing reaches contamination in building materials. Until those materials are accessed, dried, and sealed, the smell keeps coming back.
How Much Does Cat Urine Odor Removal Cost?
Inspections start at $350, depending on the size of the property and scope of damages. Call for a free phone quote. Remediation cost depends on severity, scope, and contaminated materials. Level 4 single-room work costs significantly less than Level 9–10 whole-house remediation. We provide detailed estimates after inspection. Doing it right once is always less expensive than doing it wrong three times.
Who Uses Our Cat Urine Odor Removal Service
- Homebuyers who discovered severe odor after closing

We don’t come to your home to see if we can get rid of the odor — we tell you how we’re going to do it before we even start.
Level 4 single-room: 2–3 days. Level 9–10 whole-house: 1–2 weeks. Drying time is often the limiting factor.
5-year guarantee when all identified contaminated materials are treated with our encapsulation system. If the odor returns under our standards, we come back at no additional charge and correct the problem. If we identify walls and you skip them, we can’t guarantee subfloor-only work will eliminate the odor.
Ask about the guarantee. The longer the guarantee, the more confident the company is in their work. We offer a 5-year guarantee, unmatched in the urine odor removal industry. Also ask what they specialize in. We work exclusively on dog, cat, rodent, and human urine odor — nothing else.
Get a pet odor inspection before closing. Know what’s contaminated and what remediation costs. Negotiating power. Don’t trust cosmetic updates — even a brand-new renovation can be hiding severe structural contamination. See our page on urine damage in a house for sale.
Carpet cleaners clean the carpet — great for fresh accidents and routine maintenance. We remediate the structure underneath — subfloors, concrete, drywall, framing, wall cavities. Different services for different problems. If your odor is embedded in building materials, carpet cleaning won’t solve it.
Not unsellable, but it impacts value and time on market significantly. Remediating before listing is almost always the smarter move.
Heat and humidity reactivate uric acid crystals in contaminated materials. The contamination is always present — conditions just make it louder.
Still Smelling Cat Urine? It's Not Going Away on Its Own.
If the odor has reached your subfloor, concrete, or walls, no amount of cleaning will fix it. No amount of waiting will make it fade. No air freshener, enzyme, or ozone machine will reach the source. The only way to eliminate it permanently is to access the contaminated materials and seal them at the structural level.
Every week you wait is another week living with the smell. Every dollar you spend on a method that can’t reach the source is a dollar that doesn’t get you closer to a solution. The odor isn’t going to resolve itself. But we will resolve it for you.
We may not be the first company you called. But we’ll be the last one you need. Over 35 years of experience. A proven odor remediation system that works every time. Thousands of satisfied customers. We specialize exclusively in urine odor. And our 5-year guarantee is unmatched in the industry — because we treat the source, not the symptom.
We don’t use deodorizers or masking agents. We find and eliminate the odor source. Done right, by us, the first time.
