If your Inverness home smells like dog or cat urine, store products and regular carpet cleaning won't fix it — the urine crystals are trapped deep in the pad and subfloor. We eliminate them completely. Not mask. Not reduce. Gone. Serving Inverness pet owners since 1981.

Inverness is a small, low-density Cook County village about 25 minutes east of Algonquin via IL-62 and Ela Road. What makes it unusual in our service area is the lot size and the housing scale — most Inverness homes sit on one-to-three-acre wooded parcels, and the houses themselves are almost entirely 1960s-80s custom builds of 3,500 to 6,000 square feet. That means a lot of carpet, usually across a master suite, multiple bedrooms, a main-floor family room, and a finished basement.
The pet odor pattern in Inverness is driven by the combination of that scale and the age of the housing. Many Inverness homes were built in an era when carpet pad was standard in every room of the upstairs, and that original pad is often still in place 40 or 50 years later. Add multiple pets across two or three generations of owners, and you get layered contamination spread across large carpeted areas. Summers bring the smell back every year until someone actually treats the pad.
The finished basement is the other common Inverness job. Most Inverness basements are fully finished family-and-entertainment spaces on poured concrete slabs, and that's where a senior dog's winter accidents tend to collect. We regularly treat and seal the slab through the carpet for these jobs.
Inverness families are used to working with specialists. We tell them the truth about what treatment can and cannot fix, and we stand behind the guarantee regardless of square footage.
You've scrubbed the spot, tried enzyme sprays from the pet store, maybe even hired a carpet cleaner. It smells fine for a few days — then on the next humid afternoon or when the heat kicks on, the odor is back. You're not doing anything wrong. The problem is that pet urine doesn't stay where you can reach it.
When a dog or cat urinates on carpet, gravity pulls the liquid down through the fibers, through the carpet backing, and into the pad. In repeated or severe cases, it reaches the subfloor. As the moisture evaporates, what's left behind are uric acid crystals — microscopic, odor-producing compounds that are invisible, nearly indestructible, and completely unaffected by standard carpet cleaning.
Pet urine spreads wider and deeper than the visible stain on the surface. Store products and standard carpet cleaning can't reach the crystals trapped in the pad and subfloor.
Enzyme cleaners from the pet store only penetrate the top carpet fibers. They can't reach the pad or subfloor where most of the urine has settled. You're treating 20% of the problem.
Standard carpet cleaning uses deodorizers that mask the smell with fragrance. The uric acid crystals are still there. When the perfume fades, the urine odor returns — often stronger.
A dog or cat's nose is 10,000 to 100,000 times more sensitive than yours. Even when you can't smell anything, your pet can — and will return to the same spot until the uric acid is completely eliminated.
This is why we built a process specifically designed to reach every layer — fiber, backing, pad, and subfloor — and destroy the uric acid crystals at the source. It's the only way to guarantee the odor is truly gone. See our 7-step process →
Same 7-step process for every job, refined over 40+ years. Here's the short version — for the deep-dive on each step, see the main process page.
Our Inverness-area technician arrives in about 25 minutes from our Algonquin headquarters and maps every contaminated spot before quoting.
We tell you honestly which spots are treatable and which need replacement.
We apply our urine-targeted solution directly to the affected pad and subfloor.
The chemistry breaks down uric acid crystals over a controlled wait period.
We pull contaminated solution out of the pad — not just the surface.
The carpet fibers get a complete clean as the final pass.
If you can still smell urine after the carpet dries, we come back at no charge.
We don't use stock photos or made-up stories. These are actual pet urine removal jobs from Inverness homes — with real before-and-after results.
An Inverness Ridge home with 40 years of owner turnover had layered cat-urine contamination in the master bedroom pad. UV mapped seven spots. Single long visit, full pad treatment across the room, and the smell has stayed gone through summer.
A Pine Lake home with an aging Mastiff had basement family-room accidents that two prior cleanings hadn't held. Concrete slab was the source. We treated the slab directly and re-extracted the carpet. Zero return.
A Braymore Hills custom home had three cats and a diffuse main-floor odor the owner couldn't trace. UV found twelve spots across the great room and dining area. One long visit, treated and extracted all of them.
Most carpet cleaners offer pet urine treatment as an add-on. We built our entire process around it. Here's what separates AOK from every other option in Cook County.
No other carpet cleaner in the area makes this promise. Most use hedge language like "reduces odors" or "up to 90% removal." We guarantee the odor is completely gone once the carpet dries — or we come back and retreat at no charge. If we can't fix it, you don't pay.
AOK has been cleaning carpets in Northern Illinois since 1981. We've handled thousands of pet urine situations — from a single puppy accident to multi-year cat urine saturation through the subfloor. There isn't a scenario we haven't seen.
If your carpet can be saved, we'll save it. If it can't — if the urine has saturated the subfloor beyond what treatment can reverse — we'll tell you to replace the carpet instead of charging you for work that won't hold.
Our truck-mounted system generates significantly more suction and heat than the portable units most competitors use. That extra power is what allows us to extract dissolved urine from deep in the pad.
Our treatment solutions are non-toxic and safe for children and animals once dry. No harsh chemical fumes, no residue left behind. Your pets can be back on the carpet the same day.

Both dog and cat urine cause persistent odor problems, but for different reasons. Here's how we handle each.
Dog urine tends to spread across larger areas and soaks down quickly into the pad. The volume per accident is bigger, but the urine is generally less concentrated than cat urine.
Treatment usually focuses on a few specific zones — often near doorways, water bowls, or favorite resting spots.
Cat urine is more concentrated and harder on carpet fibers. The crystals lock in tighter and reactivate with humidity.
Repeat offenders almost always require treatment of the pad and sometimes the subfloor. Full breakdown on our main page →
“Forty years of pets in the master suite carpet. AOK found all of it and treated it. The room smells normal for the first time in my memory.”
“Our Mastiff had taken over the basement. AOK treated the concrete under the carpet and the smell is gone. Best money we have spent on the house.”
“Three cats, one diffuse smell, no idea where it was coming from. AOK found twelve spots with the UV light and fixed every one.”

Cost depends on the number of affected spots, how deeply the urine has penetrated, and total square footage. Every job starts with a free UV inspection so we can give you an accurate quote based on what we actually find.
In most cases, yes. Our treatment is designed to save the carpet by neutralizing urine deep in the pad. In severe cases where the urine has soaked into the subfloor, replacement may be the better call — we'll tell you honestly which it is.
No. When the uric acid crystals are fully neutralized and extracted, the odor does not return. If you can still smell urine after the carpet has fully dried (24–36 hours), we come back and retreat at no charge — that's the guarantee.
Most jobs are completed in a single visit. A typical 2–3 room job takes about 2–3 hours including inspection, treatment, dwell time, and extraction. Carpets are walkable in hours, not days.
Yes. Our solutions are non-toxic and safe for children and animals once dry. There are no harsh chemical fumes during or after the process.
Yes — most Inverness jobs are multi-room and often span both the upstairs and a large finished basement. Our truck-mounted extraction is sized for jobs of 3,000+ square feet, and the guarantee is the same for a single zone or a full-house treatment.
We're about 25 minutes from Inverness via IL-62 east to Ela Rd. Same-week appointments most weeks. Every job is backed by our 100% odor removal guarantee — if you can still smell it, you don't pay.
