Pet Odor Removal — Los Angeles County, CA

Moved Into a Remodeled Home in Los Angeles County and the Smell Came Through the Fresh Paint?

If you closed escrow on a Los Angeles County home that looked move-in ready and now you're noticing pet odors coming through, the issue is likely hidden in the subfloor, drywall, or concrete below the surface.

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 Los Angeles 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. Our structural odor seal is designed to help contain and reduce embedded urine vapors. Backed by a 5-year written guarantee on qualifying work.

Serving Los Angeles, Long Beach, Santa Clarita, Glendale, Pasadena, Lancaster, Palmdale, Burbank, Santa Monica, Beverly Hills, Pomona, Torrance, and all Los Angeles County for 30+ years.

Common Odor Problems by Area in Los Angeles County

30+ years of work across Los Angeles County means we've seen the contamination patterns specific to each part of the county. Here's what we typically find by area.

Burbank / Van Nuys / Sherman Oaks — Smell Amplifies in Summer Heat After Years of Rental Turnover

"We just bought a house in Sherman Oaks and the smell is unbearable. Three previous tenants had cats. We've cleaned twice. Our daughter's allergies are flaring and we move in next weekend. What do we do?"

Three rounds of tenant cat urine has absorbed into the carpet pad and OSB subfloor underneath. Surface cleaning can't reach what's already past the pad.

A homeowner inherits a multi-cat property after closing escrow. Carpet contamination spans multiple bedrooms, with urine soaked through carpet and pad into the OSB or plywood subfloor. Carpet removal, subfloor sealing, and drywall treatment where staining is confirmed.

Cities served: Burbank, Van Nuys, Reseda, Sherman Oaks, Encino, Tarzana, Woodland Hills, North Hollywood, Studio City

Pasadena / Monrovia / Arcadia — Smell Returns After Cosmetic Remodel and Fresh Paint

"We closed on a 1920s craftsman in Pasadena last month. Seller refinished the floors and repainted everything before listing. The smell is back. Need to know what we're dealing with before we tear out the floors."

Here's what we found: cat urine had penetrated the original Douglas fir subfloor underneath the refinished hardwood.

Monrovia townhome — "newly remodeled" home with cat spray throughout the structure — Townhome had been recently painted and updated with new laminate flooring, new carpet, new baseboards, new doors, updated bathroom, and new kitchen cabinets. Inspection under UV blacklight revealed heavy cat spray on the kitchen wall 18 inches to 6 feet high — consistent with cats marking while standing on the refrigerator. Heavy urine deposits found on perimeter walls in the dining and living areas. Stains as high as 7 feet on the right side of the sliding glass door. Moisture detection confirmed wet urine had penetrated drywall and door jambs throughout the unit. This type of contamination typically involves cross-contamination from prior cleaning attempts (wall washing, paint rolling) that spread urine compounds beyond the original spray zones. The subfloor or slab is treated and sealed so the area is ready for new flooring installation.

Cities served: Pasadena, Monrovia, Arcadia, West Covina, Glendora, El Monte, Alhambra, Baldwin Park, Glendora

Koreatown / DTLA / Mid-City — Apartment and Condo Density: Cat Odor Migrating Through Shared Walls

"Multi-unit owner near Koreatown. The downstairs tenant just got evicted — left two cats and never used a litter box. The unit smells, but now the unit above is complaining too. Need this scoped before I can re-rent either one."

In high-density apartment and condo stock, contamination doesn't stay in one unit. Cat urine wicks into the subfloor and travels along framing into adjacent units — and through wall cavities into neighbors. Eviction cleanouts that get treated as "deep clean and re-paint" come back six months later when the next tenant smells what the paint covered.

Torrance / Long Beach / Manhattan Beach — Smell Discovered After Move-In When Humidity Rises

"Closed escrow on a Manhattan Beach home in May. Everything seemed fine. Now that summer's here and we keep the windows shut for the AC, the smell is overwhelming. Need help."

The smell is stronger when the AC is on. Cleaning can't reach pet urine that has saturated the carpet pad and the wood subfloor below.

Real South Bay Home Remodeled On Top Of Severe Cat Urine Job

Lakewood post-purchase discovery — fully remodeled home revealed cat urine inside the building materials after move-in — Buyer purchased a home where the seller had installed new kitchen, new bathrooms, and new flooring before listing. Everything looked fresh on walkthrough. Within weeks of moving in, the buyer began smelling cat urine that hadn't been detectable during showings. Inspection revealed urine compounds had wicked into the drywall, framing, and subfloor underneath the new finishes. Common pattern in cosmetically remodeled homes — surface upgrades cover what's beneath, but the odor source remains in the structural materials. The inspection provides the documented map and itemized estimate needed to determine next steps.

Cities served: Torrance, Redondo Beach, Lakewood, Manhattan Beach, Hermosa Beach, Carson, Long Beach

Santa Monica / Brentwood / Beverly Hills — Odor Behind Fresh Paint and Refinished Floors at Pre-Sale

"We're in escrow on a $3.8M property in Brentwood. The seller did a full remodel — new paint, refinished floors, new finishes. Buyers came back saying they smell something. We close in ten days. Need this resolved."

Here's what we found: cat urine had absorbed into the drywall and subfloor before the remodel — the new finishes covered it without addressing the source.

Beverly Hills Home Freshly Painted On Top Of Cat Urine Stains

A buyer's agent calls about a Beverly Hills home with new paint, refinished floors, and updated finishes — but a faint smell still surfacing. UV blacklight reveals contamination behind the cosmetic prep. The smell wasn't gone, just covered. Post-purchase discovery happens when buyers move in and find what the prep didn't address.

Cities served: Santa Monica, West LA, Brentwood, Beverly Hills, Pacific Palisades, Culver City, Mar Vista, Venice

Palmdale / Lancaster — Smell Stronger When the House Heats Up in Summer

"Bought a foreclosure in Palmdale. Previous owners had four dogs and a goat. Smell is intense — worse on hot days when the house is closed up. Tried enzyme cleaners twice. Doing a flooring tear-out next month and need this scoped before we start."

The smell is stronger when the house heats up. Multi-pet contamination over years has reached past the surface — full inspection identifies how deep before any tear-out goes ahead.

Antelope Valley Investor Realized After Buying The Odor Problem Was Too Big For His Crew To Handle

Acton multi-cat household — carpet, pad, subfloor, and concrete all contaminated — Single-family home with strong cat urine odor detectable in all carpeted rooms. Carpet had already been pulled back in some areas. Inspection revealed yellow-green urine staining under UV light across all carpet, with wet urine still present on drywall in the living room and on subfloor in the master bedroom, hallway, third bedroom, and stair landing. Common in long-term multi-cat households — contamination follows traffic patterns and concentrates at thresholds, hallway centerlines, and along baseboards. The subfloor or slab is treated and sealed so the area is ready for new flooring installation.

Cities served: Palmdale, Lancaster, Acton, Quartz Hill

Whittier / Downey / Pico Rivera — Concrete Slab Smell After Carpet Removal Over Concrete

"Pulled the carpet in our Whittier house ourselves to save money on the remodel. The slab smell is overwhelming — our contractor refused to lay new flooring over it. Need this sealed this week or the project stops."

Once the carpet came up, the dog urine had seeped into the concrete slab below. The slab gets sealed before any new flooring goes down.

Real South East LA Dog Urine Odor Removal Subfloor & Concrete Job

A homeowner pulls up the carpet to install new flooring and the contractor walks off the job because of the smell from the slab. Years of pet urine have reached the concrete. Concrete sealing required before new flooring goes down — carpet over a contaminated slab will not hold the smell back.

What Caused the Odor

Where to Start / Special Situations

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 ready for new flooring — 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.

Frequently Asked Questions — Los Angeles County

Do you actually come out to Los Angeles County?

Yes. Los Angeles County is within our regular service area. We cover LA, Long Beach, Santa Clarita, Glendale, Pasadena, Burbank, and all surrounding communities.

Do you work with multi-unit buildings, fourplexes, and apartment owners?

Yes. A large share of our LA work is multi-unit — apartment buildings, fourplexes, condos, and HOA-managed properties where contamination can migrate between units through framing and shared walls. We document scope per unit and treat structurally so the next tenant doesn't smell what the prior one left behind.

How much does pet odor removal cost in Los Angeles County?

Cost depends on contamination scope, surfaces affected, and square footage. Every project starts with our inspection, which produces an itemized estimate. Free phone quote available.

Do you work with Los Angeles County real estate agents?

Yes. We regularly work with Los Angeles County real estate agents on pre-listing remediation, post-purchase discoveries, and disclosure disputes. Work is coordinated with the property owner or their contractor as needed.

How long does the project take?

Most full-home projects are completed in several working days. The exact timeline depends on the size of the home and severity of contamination — your inspection report includes a project-specific timeline. The job isn't complete until the odor is gone and you approve it during the final walkthrough.

How long after treatment will the odor be gone?

In most cases, once sealing is complete, the odor is gone within 24 hours. Extreme cases may require a double coating but that's rare.

Is the 5-year guarantee in writing?

Yes. We provide a 5-year written guarantee on qualifying work. Documented on every project.
