Pet Urine Damage
Goes Deeper Than Carpet.
Surface cleaning removes what you can see and smell temporarily — but urine that has soaked through the carpet, into the padding, and down to the subfloor requires a different approach entirely. We go all the way down and fix it right.
The honest truth most companies won't tell you: When pet urine soaks through carpet and padding, it pools on the subfloor and crystallizes. Steam cleaning or even professional hot water extraction only treats the carpet face. The odor source is below — and it will keep coming back every time humidity rises until it's properly addressed.
Cleaning Only Gets The Surface.
Pet urine doesn't just sit on top of carpet. It wicks down through the carpet fibers, saturates the padding underneath, and soaks into the subfloor below. The padding acts like a sponge — it holds urine long after the carpet surface appears clean.
When humidity rises — especially here in Portland — those uric acid crystals in the padding and subfloor reactivate and the odor returns. That's why professionally cleaned carpet can still smell like urine weeks later.
The only way to fully eliminate pet urine odor is to address every layer it reached. That means pulling the carpet, removing the affected padding, treating and sealing the subfloor, and reinstalling with fresh materials.
Cleaning the carpet face
Removes surface contamination and temporarily reduces odor. The urine in the pad and subfloor remains. Smell returns — often within weeks — especially on humid Portland days.
The Carpet Surgeon approach
Pull carpet and pad, clean and seal the subfloor, install new pad and tack strip, reinstall or replace carpet. The odor source is eliminated — not masked. Done once, done right.
Surface cleaning + pet urine treatment
When damage is caught early and hasn't reached the subfloor, our specialized pet urine cleaning process can be effective. We'll assess honestly and recommend the right approach for your situation.
Our Full Restoration Process
Every photo below is from an actual Carpet Surgeon job. This is what proper pet urine restoration looks like — no shortcuts.
Assess the Damage
The first step is understanding the full extent of the damage. What's visible on the carpet surface is almost never the whole picture. We use blacklight inspection and moisture testing to map exactly where urine has penetrated — and how deep it's gone. No guessing. No assumptions.
Pull the Carpet & Expose the Pad
We carefully pull back the carpet to expose the padding beneath. In almost every severe urine case, the pad is heavily saturated — you can see the discoloration and often smell it immediately. This is what surface cleaning leaves behind. The pad must come out.
Remove Pad & Expose the Subfloor
Once the padding is removed, we can see the subfloor. Urine that has soaked through the pad leaves visible staining on the wood or concrete below. This is the odor source. Until this surface is treated and sealed, the smell will never fully go away — no matter how many times the carpet is cleaned.
Clean & Seal the Subfloor
We treat the subfloor with a professional enzymatic cleaner to break down the uric acid crystals, then apply an odor-blocking sealant. This locks in any remaining odor molecules and creates a barrier so they can't reactivate. This step is what makes the fix permanent.
Install Fresh Padding & Tack Strip
With the subfloor clean and sealed, we install new padding and replace any tack strips that were saturated. Fresh pad means no residual contamination coming back up. The carpet now has a clean, dry, odor-free foundation to sit on. Everything below is brand new.
Replace or Reinstall the Carpet
Depending on the carpet's condition, we either reinstall the original carpet (cleaned with our pet urine treatment process) or replace the affected section. When replacing, we often pull carpet from a hidden area like a closet — using matching carpet so the repair is invisible. The closet gets a similar replacement so nothing looks out of place.
Full Tack Strip & Pad Replacement
On heavily affected areas, we replace all tack strips as well. Tack strips absorb urine at the carpet edges and hold odor even after everything else is cleaned. This photo shows a separate job where we pulled all tack, sealed the floor completely, and installed fresh tack and padding throughout. Nothing is reused if it was contaminated.
Everything We Offer for Pet Urine Damage
We assess each situation and recommend the right level of treatment — from surface cleaning to full subfloor restoration.
Urine Damage Assessment
Blacklight and moisture testing to map exactly where urine has penetrated and how deep. Always free, always honest — we tell you what you actually need.
Pet Urine Carpet Cleaning
When damage hasn't reached the subfloor, our specialized pet urine hot water extraction process — with enzyme pre-treatment — can effectively eliminate odor and staining.
Pad Removal & Replacement
Pull and dispose of contaminated padding, clean and seal the subfloor, install fresh padding and tack strip. The permanent solution for deep urine damage.
Subfloor Cleaning & Sealing
Enzymatic treatment of the subfloor followed by professional odor-blocking sealant. Locks in remaining odor molecules permanently so they can never reactivate.
Carpet Section Replacement
When carpet is too damaged to save, we replace affected sections — often using matching carpet pulled from a closet so the repair is seamless and invisible.
Full Restoration Package
Assessment, pad removal, subfloor treatment and sealing, new tack strip, new pad, carpet reinstall or replacement. The complete fix — done once, done right.
