Pet Odor Removal — Orange County, CA
Bought a Home in Orange County and Now It Smells Like Cat Urine Coming Through the Subfloor?
Most Orange County buyers find us within days of moving in — they walked the home twice, signed the papers, and now the smell is unbearable. Surface cleaning won
If you’ve already tried cleaning and the smell keeps coming back, the problem is not on the surface.
Cleaning may remove visible urine, but when the smell remains, the odor is coming from urine embedded below 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.
In many Orange County homes, the urine is embedded in the subfloor, drywall, or concrete below the surface. It will continue to come back until the source is properly identified and treated.
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.
Serving Anaheim, Santa Ana, Irvine, Huntington Beach, Garden Grove, Orange, Fullerton, Costa Mesa, Mission Viejo, Westminster, Newport Beach, Lake Forest, and all Orange County for 30+ years.
Most projects start with a quick phone call to determine if an inspection is needed.
If you can smell it, we can find it. If we can find it, we can eliminate it at the source.

If This Sounds Familiar
If You're Dealing With Any of These — You're in the Right Place

- Bought a home in Orange County and now it smells like cat urine

- Removed old flooring and the smell is still there
- Our pets ruined our carpet and we're replacing it — we want the subfloor odor gone before new carpet is installed
- You've already tried cleaning and the smell keeps coming back
- Planning new flooring installation and need subfloor evaluated first
Local Patterns We See
Common Odor Problems by Area in Orange County
30+ years of work across Orange County means we’ve seen the contamination patterns specific to each part of the county. Here’s what we typically find by area.
Anaheim / Fullerton / Buena Park — Smell Through Fresh Paint After Closing
Closed on a house in Anaheim last week. Seller painted everything before we closed but my wife is allergic to cats and the smell is still coming through the walls. We can't move in like this — what do we do?
Here’s what we found: the odor was coming through the paint from cat spray absorbed into the drywall.

Santa Ana / Garden Grove / Orange — Carpet Pulled Mid-Renovation, Subfloor Reeks
Our flooring guy pulled up the carpet in our Orange townhome yesterday and the smell hit us like a wall. He won't install LVP over it. We need this fixed before he comes back Monday — what do you charge to seal a subfloor?
Once the carpet came up, cat urine had penetrated the OSB subfloor below. New flooring laid over it traps the source, so the subfloor gets sealed before the new floor goes in.

Mission Viejo / Lake Forest / Aliso Viejo — Dog Urine on Garage Concrete from Years of Kennel Use
We kept our two dogs in the garage for the last six years. Now we're listing the house and our agent says the garage smells like a kennel. We've pressure-washed it three times. Doesn't matter. The smell is in the concrete itself. Listing photos next Wednesday.
The odor wasn’t on the surface — dog urine had saturated the concrete slab. Pressure washing pushes the contamination further in, not out. The slab itself gets sealed before pre-listing presentation work.

Huntington Beach / Newport Beach / Laguna Beach — Buyer in Escrow with Allergy, Smell Detected
We're about to close escrow on a house that smells like cats and I'm allergic. The flooring installer pulled up a corner of the carpet and the odor was very strong. Our agent says we need this resolved or buyers walk. Need help.
Here’s what we found: cat urine had absorbed into the carpet pad, wicked into the subfloor, and bled into lower drywall sections — all reactivated by the marine humidity. The inspection report tells the buyer what we found, what it will cost to fix, and gives them the information they need to decide how to proceed.

Westminster / Cypress / Stanton — Tenant Moved Out, Next One Signs Friday
Tenants moved out of our Costa Mesa duplex last week with two cats and a dog. The unit reeks. Our cleaner spent eight hours and said it's not coming out. Next tenant signs Friday and they're already asking about the smell. We need someone fast.
The cleaner couldn’t reach what was already past the surface — cat urine and dog urine had saturated the carpet pad, wicked into the subfloor, and trapped in lower drywall. Multi-substrate remediation gets the unit re-rentable before the move-in date.

Where to Start / Special Situations
Pet Odor Inspection
Required first step on every project. Itemized estimate, written summary report.
Baseboard Odor Damage
Swollen, contaminated baseboards from urine wicking or water intrusion.
Carpet Removal Service
Full carpet and pad removal when contamination has saturated flooring materials.
If You Wait
What Happens If You Don't Fix It
Odor inside materials doesn’t go away — it becomes more noticeable as the home heats up, closes up, or sits over time.
The smell intensifies
Urine remains embedded in subfloor, drywall, concrete, or framing and reactivates 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 indoor humidity.
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 slab so it’s clean and odor-free — ready for your contractor or flooring installer.
Remediation cost increases
The longer urine sits in subfloor, drywall, and framing, the deeper it penetrates. Today’s $3,500 job is next year’s $7,500 job.
Property value drops
Pet urine odor can reduce resale value by 5–15% — often more than the cost of proper remediation.
Remediate now, or remediate later at higher cost.
