Cat Urine Odor
Cat Urine Odor Removal — Structural Remediation
Whole house smells like cat urine? Cleaning reaches the surface — the urine is in the subfloor, drywall, or concrete. Most people land here after other services and cleaning products addressed the surface but the smell keeps returning.
Cat urine is the most aggressive pet odor we deal with; the compounds penetrate carpet, pad, subfloor, drywall, baseboards, and concrete. We’re not a cleaning service — we solve odor problems inside the building materials. Our structural odor remediation is backed by a 5-year written guarantee on qualifying work.

Why cat urine is different
Cat urine is chemically aggressive — its compounds bond to porous building materials (subfloor wood, drywall paper, concrete pores, baseboard MDF) at a molecular level.
Felinine
Breaks down into volatile sulfur compounds — worse the longer it sits.
Uric acid crystals
Reactivate every time moisture or humidity rises — even year-old contamination comes roaring back on a humid day.
Hormonal markers
Intact males produce potent urine that triggers more marking.
Bacterial breakdown
Produces ammonia and more sulfur compounds over time.
Where surface treatments stop working
Cleaning may remove visible urine but not the invisible odor inside the material — that’s why you can smell it even when you can’t see it.
Aged, accumulated, or marking contamination has usually absorbed into subfloor, drywall, or concrete, which requires a different approach than surface cleaning.

The 5-Year Written Guarantee
Qualifying surfaces treated with our proprietary Odor Encapsulator are backed by a written 5-year guarantee, subject to the documented treatment scope and written terms. The Odor Encapsulator is designed to help contain and reduce embedded urine vapors in the materials it is applied to.
It addresses pet-urine odor in the specific structural materials we treat. It does not make the property impervious to future pet accidents or odor from other sources, and it does not apply to inspections, estimates, oxidizer-only treatments, or allergen services.
