Start Here — What best describes your situation?
Most people fall into one of these:
Hoarding cleanup with severe pet contamination
Property is uninhabitable due to combined urine and biological hazards
Multi-pet death situation requiring full structural cleanup
Tenant abandoned property with severe biohazard conditions
Foreclosure or estate property with extreme contamination
Real estate property too contaminated to list as-is
Biohazard Odor Cleanup — When the Situation Has Gone Past Normal
When Standard Cleanup Isn't Safe — and Standard Companies Won't Take the Job.
Some situations have moved past what surface cleaning, professional carpet cleaners, or routine pet odor work can handle. Hoarder conditions. Severe multi-animal contamination. Biological accumulation from long-term neglect. Estate properties where decades of contamination have built up. These aren't normal projects, and they don't get treated like normal projects.
If you’re calling about a parent’s home, a tenant property, or an estate where the contamination is severe — you don’t have to be the one figuring out how to handle it. We’ve handled these for over 30 years.
These projects involve real health risks — pathogens in dried waste, ammonia exposure in confined spaces, biological residue inside structural materials. They require proper PPE, containment protocols, and biohazard disposal. They also require something most cleanup companies don’t offer: discretion. We handle these jobs without judgment of the homeowner, the family, or the circumstances that led there.
This is not a service you should DIY. It’s also not a service most cleanup companies will take. We do it because it needs doing — and we’re set up to do it safely.
Our structural remediation is backed by a 5-year written guarantee. Discretion is built in.
This service handles severe contamination at the structural level — safely, discreetly, and completely.
Call when you're ready — we'll listen first.

You may also be dealing with:
You walked into the property and didn't know where to start.
The smell. The damage. The scope of what needs to happen.
You called a couple of cleaners. They quoted, looked, then declined the job.
That's why you're here.
We’ve handled hundreds of these situations. Quietly. Completely. Without judgment. You’re not the first family to make this call — and you don’t have to figure this out alone.
If you haven't had an inspection yet, start there first.
Most problems involve multiple surfaces, and treating one area without a full diagnosis can waste time and money. Our inspection identifies which surfaces are actually contaminated — so the remediation plan addresses the real scope, not just what’s visible.
Quick Qualifier
Make Sure This Is the Right Service
This service is for:
- Hoarder conditions or severe long-term neglect
- Whole-house multi-pet contamination beyond standard remediation
- Estate, eviction, or trauma-affected property cleanup
This is NOT for:
- Standard pet odor or single-room contamination
- Crime scene or unattended-death cleanup (specialized)
- Hazmat or chemical contamination (different specialty)
We handle severe pet and biological contamination — safely, structurally, and discreetly.
If standard cleanup companies have declined the job — that's why we exist.
The Reality
This Isn't a Cleaning Project.
It's Not Safe to Ignore — and Not Safe to DIY.
When biological contamination has built up over months or years, the situation crosses a threshold. Dried animal waste contains pathogens that aerosolize when disturbed. Ammonia concentrations in confined spaces can reach levels that cause real respiratory harm in minutes. Decomposed material in carpet, furniture, and building materials contains bacteria that standard cleaning supplies aren’t formulated to address.
This isn't something that can be handled with standard cleaning methods. The materials, the contamination, and the safety considerations are different.
A family member who tries to “just start cleaning it up” can end up with respiratory irritation, infections from contaminated surfaces, or simply overwhelmed within an hour of starting. This is not a failure of effort. It’s a problem that requires PPE, containment, and biohazard disposal — not a stronger cleaner.
In situations like this, it’s not just about odor. It’s about knowing what is safe to handle — and what isn’t.
You don't have to figure this out yourself. That's what we're here for.
Standard pet odor remediation handles standard cases. When the situation has moved past standard, that’s the line where this service begins.
The Severity Threshold
Why Severe Contamination Requires a Different Approach
Here's what makes these projects fundamentally different:
It's not just more contamination. It's a different category of problem.
A single accident or even years of moderate pet activity can usually be addressed through standard remediation: remove the carpet, treat the subfloor, replace the materials. Severe contamination crosses into territory where the contamination itself is biologically active, structurally invasive, and hazardous to handle without proper protocols.
The threshold isn't always obvious from outside the property. Inside, it usually is.
What Crosses the Threshold
Pathogen load
dried animal waste, biological residue, and fecal accumulation harbor bacteria and pathogens. Disturbing them without containment aerosolizes the contamination.
Ammonia exposure
concentrated urine in poorly-ventilated spaces creates ammonia levels that cause respiratory injury within minutes of unprotected exposure.
Painted finish only on the front
the manufacturer paints the visible faces. The back, bottom, and cut ends are usually raw wood or raw MDF — exposed to absorption from any direction.
Insect and biological activity
long-term contamination attracts secondary contamination: maggots, mites, mold, bacterial colonies. These compound the problem and the health risk.
When two or more of these are present, the project has crossed into biohazard territory.
What This Service Includes
This isn’t an upsold version of standard cleanup. It’s a different operational approach.
PPE protocols on every team member: respirators, Tyvek suits, gloves, eye protection. Contained removal of contaminated materials with sealed disposal protocols. Biohazard disposal procedures for the materials we extract. Structural treatment of the underlying framing, subfloor, and drywall after removal. Verification at completion.
We also handle these projects with discretion. We don't park branded vehicles where they'll draw attention. We don't discuss the property with neighbors. The project is between us and the family or the executor — no one else needs to know.
If you've called other companies and they've declined, or quoted in a way that made it clear they don't actually want the job — that's the pattern. Severe contamination work isn't a normal call. It requires setup, protocols, and crew that most odor and cleaning companies don't have. We've been set up for this since 2012.
Audience Match
Real Biohazard Cleanup Scenarios We Handle
Start here — find your situation: Every scenario below is a project we’ve handled. If yours isn’t on the list but feels related, the call is still the right next step.
- ★ Most Common Call
"My parent's home — we didn't realize it had gotten this bad"
Adult children calling about an aging parent’s property. Sometimes the parent is still living there; sometimes they’ve passed or moved to assisted living. The contamination has built up gradually over years and is now overwhelming. We work with the family on pace, scope, and discretion. No judgment of the parent or the family. The call is confidential.
- ★ Most Common Call
"Severe multi-pet contamination — way past standard remediation"
Hoarding-pattern situations involving large numbers of cats, dogs, or other animals, where contamination has saturated flooring, walls, furniture, and HVAC systems throughout the property. Standard pet odor work isn’t sufficient at this scope. Whole-property remediation including disposal, structural treatment, and reconstruction prep.
- ★ Most Common Call
"Estate property — we need to sell it but it's not showable"
Executors and adult children dealing with estate properties post-passing. The home often hasn’t been touched while the family processed the loss. Remediation needs to happen before listing, walkthroughs, or in some cases probate inspection. Documentation provided for estate, insurance, and disclosure purposes.
- ★ Most Common Call
"Tenant left the property in extreme condition — eviction or abandonment"
Landlords and property managers calling about properties left in conditions far beyond normal turnover. Pet contamination, biological accumulation, abandoned property and waste throughout. We document the scope for legal/insurance use and remediate to a re-rentable condition. See our tenant move-out pillar for context.
If you're in this situation, the next step is a call. We'll listen first, then talk through what's involved.
"Inherited property — decades of accumulation"
Properties passed down through the family that haven’t been cleared in 20+ years. Contamination from animals, deferred maintenance, water intrusion, biological accumulation. Often discovered during pre-sale prep or while clearing personal effects.
"Investor-acquired distressed property"
Real estate investors purchasing properties that need biohazard remediation before any rehab work can begin. Documentation-grade scoping for renovation budgeting and insurance. We work directly with the rehab GC to coordinate sequencing.
Whichever scenario matches yours — the first call is the hardest. After that, we handle it.

Where It Concentrates
Where Severe Contamination Tends to Build Up
Cat urine doesn’t spread evenly. It concentrates in patterns. This is where we find it.
Whole-Property Flooring Saturation
In severe long-term cases, carpet, pad, and subfloor are saturated across multiple rooms — sometimes the entire property. Hard-surface flooring isn’t immune: tile grout, vinyl seams, and hardwood joints absorb contamination over time. Whole-property flooring removal is common in these projects.
Furniture, Mattresses & Soft Goods
Upholstered furniture, mattresses, and soft goods absorb biological contamination beyond what can be cleaned. In severe cases, these items typically can’t be remediated — they need to be disposed under proper protocols, and replaced after the structure is treated.
Walls, Lower Drywall & Baseboards
Long-term contamination at floor-line wicks up the bottom 12-24 inches of drywall and saturates baseboards. In severe cases, contamination can run higher — full-wall replacement zones rather than spot repair. Drywall remediation is part of the scope.
HVAC, Ductwork & Air Handlers
HVAC systems running through severely contaminated properties absorb and redistribute the contamination. Ducts, return air boxes, filters, and the air handler all need attention. Otherwise the system continues to spread the problem to “clean” rooms after remediation.
Under Furniture, Behind Appliances
Spaces concealed for years often hold the most extreme contamination. Under beds and dressers, behind refrigerators and stoves, inside laundry alcoves. These zones are typically discovered only after the property has been cleared of belongings — and the scope often expands at that point.
Attics, Crawlspaces & Garages
Adjacent spaces often share air with the main living area. Garage contamination, attic rodent activity (see our rodent service), and crawlspace accumulation all contribute to the overall property contamination scope.
Severe contamination is rarely contained to one space. The full scope shows up during inspection.
We address the property at full scope — not piecemeal cleanup of the loudest rooms.
Why This Can’t Wait
What Happens If This Goes Unaddressed
Biohazard-level contamination doesn’t stabilize on its own. Each week of waiting, the biological activity continues. Pathogens remain viable. The property continues to degrade. Most importantly: anyone entering the property without protection — including family members trying to “just check on it” — is exposing themselves to real, measurable health risk.
This is the one service category where waiting genuinely makes things worse — for the property, for the family, and for anyone with access to the home.
Direct Health Risk to Anyone Entering
Pathogens, ammonia exposure, mold spores, and biological contamination affect respiratory health, eye health, and skin. Family members “checking on the property” without PPE expose themselves with every visit. Severity scales with both contamination level and time spent on-site.
Structural Damage Compounds
Untreated biological contamination breaks down wood framing, subfloor, drywall paper, and insulation over time. What might have been a remediation project becomes a remediation-plus-reconstruction project. The longer the wait, the more rebuilding becomes part of the scope.
Property Value Continues to Decline
A property in this condition is unsellable on the open market and unrentable to most tenants. Until the remediation is complete, the property is effectively held in stasis — and ongoing degradation reduces its eventual market value further.
Insurance & Disclosure Complications
Some severe contamination situations involve insurance claims, estate proceedings, or disclosure obligations to potential buyers. Documentation produced during proper inspection serves all of these. Without documentation, the path forward is harder.
Family & Caretaker Strain
Family members who feel responsible for “handling it themselves” often end up burned out, sick, or in conflict with each other before the property is addressed. Calling in help isn’t giving up. It’s recognizing this is bigger than what one person can handle alone.
Secondary Contamination Develops
Long-standing biological contamination attracts insects, rodents, and bacterial colonization. What started as one problem becomes layered with secondary contamination — making the eventual remediation more involved and more expensive than addressing it earlier would have been.
When standard solutions don't fit, the situation has reached a level where waiting genuinely costs more than addressing it. A phone call is the first step, and we'll listen first before talking through scope.
If this is what you're dealing with, call now and get the exact scope and cost.
The Process
How We Handle Severe Contamination Projects
We handle everything step by step — so you don't have to manage the process yourself:
No surprises. No judgment. No shortcuts on safety.
Confidential Inspection
We start with a confidential on-site inspection. Documentation-grade scoping with full PPE. Output: itemized estimate showing materials to remove, structural treatment scope, disposal protocols, and projected timeline. We talk you through it without pressure.
Containment & Setup
Project area is established. Containment barriers, negative-pressure setup where needed, PPE protocols for the entire crew. We don’t park branded vehicles where they’ll draw attention. The neighbors don’t need to know what’s happening at the property.
Contaminated Material Removal
Carpet, pad, contaminated furniture, soft goods, baseboards, and affected drywall are removed under proper biohazard protocols. Sealed disposal. The structure comes back to bare materials so the actual scope is visible — and addressable.
Structural Treatment
Exposed subfloor, framing, accessible drywall back-sides, and concrete receive our proprietary Odor Encapsulator. The product penetrates the porous materials, bonds at the molecular level, and locks any remaining trace contamination inside the substrate.
Verification & Sign-Off
Before we close the job, we verify the property is structurally clean. The reconstruction phase (drywall, flooring, paint) is handled separately. 5-year guarantee on the structural treatment starts the day we sign off.
At the end of this process, the property is safe to enter without PPE, the contamination is gone from the structural materials, and the family can move forward.
Our structural remediation is backed by a 5-year written guarantee.

Services Often Combined With This Work
Severe contamination projects rarely involve just one surface. The full property scope often touches multiple specialty services:
For multi-cat hoarding cases that haven’t quite reached biohazard threshold but are well past standard scope. Whole-house cat urine remediation is our most common project type.
Almost always part of severe contamination scope. Once the carpet and pad come out, the subfloor below requires structural treatment before any new flooring can be installed.
Severely contaminated properties often have secondary rodent activity in attics and crawlspaces. Both projects can run in parallel as part of the overall property remediation.
Required first step. The inspection produces the documentation needed for estate, insurance, legal, and renovation budgeting purposes — and the itemized scope.
For tenant move-out scenarios involving severe contamination, see also our tenant pet damage pillar. For homes where the family is processing significant change (death, illness, relocation), the call is the first step — we’ll listen first and figure out the right path together.
FAQ
Frequently Asked Questions
Cost varies widely based on property size, contamination scope, materials requiring disposal, and structural treatment scope. Severe contamination projects are typically larger than standard remediation — but every project starts with our inspection, which produces an itemized estimate. Free phone quote available — call 877-386-3677 and we’ll listen first.
Yes, completely confidential. We don’t park branded vehicles where they’ll draw attention. We don’t discuss the property with neighbors. The project is between us and you — or whoever has authority over the property. Discretion is built into how we work, not an upcharge.
For severe contamination, no — and not because of cost. Pathogens, ammonia exposure, and biohazard materials in dried waste pose real respiratory and skin health risks. Most family members underestimate the scope until they’re on-site, then end up overwhelmed within an hour. PPE, containment, and proper disposal protocols matter on these projects. This is the one situation where DIY genuinely isn’t safe.
It depends on the situation. Some projects can be staged so the resident remains in part of the property while we work. Others require temporary alternative housing during the work. We’ve handled both. The conversation about how to coordinate is part of the inspection. We approach it with care for the resident, not just efficiency for the project.
We provide documentation-grade scoping reports, photographic documentation, itemized estimates, and post-completion verification. These are useful for estate proceedings, insurance claims, disclosure requirements, and renovation budgeting. We work with attorneys, executors, and listing agents regularly.
Our structural remediation is backed by a 5-year written guarantee. Every area treated with our Odor Encapsulator is covered. If odor returns in a treated area within 5 years, we retreat at no charge. After remediation, the property is structurally clean — the reconstruction phase (drywall, flooring, paint) brings it back to fully finished condition.
Every week the property sits in this condition is another week the contamination is active, the structure degrades, and anyone entering takes on health risk.
One number. Itemized. From the team that takes the jobs others won't.
