OdorXpert™
Who Do You Call When the Whole House Smells Like Cat or Dog Urine?
Most people land here after other services and cleaning products have addressed the surface but the smell keeps returning — if that’s you, you’re in the right place.
If you’ve already tried cleaning and the smell keeps coming back, the problem is not on the surface.
If you haven’t identified where the odor is coming from, you’re guessing — and guessing is what leads to repeated cleaning, failed repairs, and wasted money.
Bought a home that smells like cat urine. Tenant moved out and left dog urine behind. Entire house smells like cat pee. Garage concrete smells like urine and you’ve cleaned it over and over — and it’s still there.
If you’re here, you’re not dealing with a surface problem. You’re dealing with urine embedded in the subfloor, drywall, concrete, or framing below the surface.
We’re not a cleaning service — we identify and treat urine odor embedded in the subfloor, drywall, concrete, and framing below the surface. Backed by a 5-year written guarantee on structural odor remediation.
30+ years serving California — Los Angeles, Orange, San Diego, Ventura, Riverside, Santa Barbara, and counties statewide.

Every Real Odor Problem Starts With an Inspection
Cleaning may remove visible urine, but when the smell remains, the odor is coming from urine embedded below the surface.
If you don’t identify the source, you will never get rid of the odor.
Every decision — what to remove, what to treat, and what it will cost — depends on identifying that source.
Our Pet Odor Inspection Service finds the source, maps the scope of contamination, and documents the damage. You get an itemized estimate and a written summary report — a professional document that works hard for you in disclosure issues, real estate negotiations, and more.
And the smell keeps coming back.
None of those methods reach urine that has soaked into the subfloor, drywall, concrete, framing, or wood. That’s structural urine damage — and it can’t be cleaned, deodorized, or painted over.

- Rodent Odor Removal Urine, feces, and infestation odor from mice, rats, and other rodents in walls or attics.

- Carpet Removal Service Full carpet and pad removal when contamination has saturated flooring materials.
If You're Dealing With Any of These — You're in the Right Place
- Bought a home and now it smells like cat urine
- Tenant moved out and left pet urine odor behind
- Removed old flooring and the smell is still there
- House smells worse when closed up or in warm weather
- You’ve already tried cleaning and the smell keeps coming back
- Planning new flooring installation and need subfloor evaluated first
Every one of these comes back to urine embedded in the subfloor, drywall, concrete, or framing below the surface. Every one is addressed by the services above.
What Happens If You Don't Fix This
Pet urine inside building materials doesn’t improve on its own. It gets worse.
The smell gets stronger over time
Urine can remain embedded in subfloor, drywall, concrete, or framing and reactivate when temperature or humidity changes — which is why the smell often gets stronger when the home warms up, when windows have been closed, or after rain raises the humidity inside the house.
New flooring over contamination doesn’t last
New flooring may temporarily suppress the odor, but if the subfloor or concrete is contaminated, the smell will come back. We remove contaminated flooring and dispose of it, then treat the subfloor or concrete so it’s clean and odor-free — ready for your contractor or flooring installer.
Property value drops
Pet urine odor is one of the most common buyer dealbreakers. An odor problem in your home reduces resale value by 5-15% — often more than the cost of proper remediation.
Disclosure liability grows (if you’re selling)
California requires sellers to disclose known material defects. A known pet odor issue that’s not disclosed is grounds for post-closing lawsuits. Documented remediation protects you legally.
Remediation cost keeps increasing
The longer urine sits in subfloor, drywall, and framing, the deeper it penetrates. What’s a $3,500 job today may be a $7,500 job next year.
The math is simple: remediate now or remediate later at a higher cost.

What You've Already Tried — And Where It Stopped Working
Most of our clients have already tried everything:
- Ozone machines
- Hydroxyl generators
- Chlorine dioxide treatments
- Enzyme cleaners
- Repainting walls
- Replacing flooring
- Scrubbing concrete over and over
And the smell keeps coming back.
None of those methods reach urine that has soaked into the subfloor, drywall, concrete, framing, or wood. That’s urine embedded below the surface — and it can’t be cleaned, deodorized, or painted over.
When the smell is coming from urine embedded in the subfloor, drywall, concrete, or framing below the surface, surface methods cannot reach the source.
Every Job Falls Into One of These Patterns. See Yourself in Any of Them?
The Stinky Clean House
Looks new — but smells bad. Everything was just cleaned, but the odor is still there.
The Hide-the-Stink House
Properties intentionally covered up to hide the urine damage from prospective buyers.
The Masked House (formerly “Pooperi”)
Staged with furniture, candles, plug-ins, and fresh air fresheners in every room.
The Flipped Flop House
The remodeled home that looks brand new but will have to be torn apart to get rid of the odor and put back together.
The DIY Delight House
First-time buyers or owners trying to fix it themselves without removing the source.
Sometimes the issue is disclosed on the Seller’s Questionnaire. Many times it isn’t — even though the questionnaire is specific to previous urine damage.
Either way, the smell is still embedded in the subfloor, drywall, concrete, or framing below the surface.
A visible stain doesn’t always mean there’s an odor — and an odor doesn’t always mean there’s a visible stain. That’s why surface cleaning often misses the problem. Cleaning may remove visible urine, but it doesn’t always remove the invisible odor stain left behind in the material.
Our Process — How Whole House Odor Removal Works
Step 1 — Free Phone Quote
Call for a free phone quote — we'll give you a realistic range based on your situation. If you can describe what you're dealing with, we can give you an idea of what it will take to remediate and a realistic price range.
Step 2 — Pet Odor Inspection
UV black light, moisture detection, odor and stain mapping, photo documentation, written report, and an itemized estimate delivered to your email within 24-72 hours.
Step 3 — Remediation
We remove what's contaminated, dry what's wet, and seal the substrate with our proprietary Odor Encapsulator. Starting with urine-stained carpet removal, we remove drywall as needed, dry out the structure, and seal the exposed substrate.
Step 4 — 5-Year Written Guarantee
Every area treated with the Odor Encapsulator comes with a 5-year guarantee in writing. If odor returns in a treated area within 5 years, we retreat at no charge.
Why OdorXpert
30+ Years and Thousands of Properties
Started in 1989. Serving cities across California. Thousands of completed structural remediations.
5-Year Written Guarantee
Every area treated with the Odor Encapsulator is covered for 5 years in writing. If odor returns, we retreat at no charge.
Structural Odor Remediation, Not Surface Cleaning
We’re not carpet cleaners. Not deodorizers. Not janitorial. We come in when the contamination has reached the structure.
Different Tools for Different Zones — No Ozone, No Hydroxyl, No Chlorine Dioxide
Ozone, hydroxyl generators, and chlorine dioxide can be effective for odors in the air and on exposed surfaces. When contamination has soaked into materials like subfloor, drywall, or concrete, those materials continue to release odor from within — which is the zone we work in.
Hidden Damage Detection on Flipped Properties
We read the layers a flipper applied — Odo-Ban, fresh paint, new flooring, shellac, fresh texture — and work backward to find what’s underneath.
Owner-Operated by a Certified Home Inspector
Pet odor inspections are conducted by a certified home inspector with water damage training and 30+ years of structural odor experience.
