If your Gurnee 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 Gurnee pet owners since 1981.

Gurnee is at the far east edge of our service area — about 50 minutes from our Algonquin headquarters via IL-22 and IL-21 — but it's a regular run for us because Lake County keeps us busy and Gurnee's housing fits squarely in our wheelhouse. Most of the village was built out around 1988, give or take a few years, in the planned subdivisions of Fairway Ridge, The Oaks, Pembrook, The Pines, and Riverside Heights. The architectural fingerprint is consistent: split-levels and two-story Colonials with attached two-car garages, modest front yards, and finished basements.
What that means for pet odor: most Gurnee homes have synthetic carpet on plywood subfloors, original to the 1985-1995 build. The pad isn't ancient but it's been there 30-40 years and has absorbed whatever pet history the home has accumulated. The most common Gurnee call is a young family that bought a 1980s subdivision home from the original owners (whose senior dog or cat had aged in place), and they're noticing a smell in the lower-level family room that surface cleaning hasn't touched.
Finished basements are also a major Gurnee pattern. Almost every single-family home in Pembrook, Timberwoods, and Fairway Ridge has a downstairs family room with carpet over concrete slab, and that's where dogs tend to have winter accidents. Concrete subfloor holds uric acid for years.
Gurnee is also the home of PetSmart and the Banfield Pet Hospital inside it, and Animal Hospital of Gurnee — both refer customers to us when their clients describe a home that smells like the problem they're trying to solve.
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 Gurnee-area technician arrives in about 50 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 Gurnee homes — with real before-and-after results.
A Fairway Ridge family with an aging Golden Retriever had been managing basement accidents through the dog's last winter. Our blacklight found six overlapping deposit zones. Single-visit treatment, full extraction, and the basement is finally usable as a family space.
A Oaks family with two large dogs had been masking great-room odor with plug-ins for months. UV inspection found seven spots near the back patio door. Single-visit treatment, full pad extraction, and the smell hasn't returned through a full summer.
A new owner of a 1989 Pembrook home found cat smell in the master bedroom from previous owners. UV showed five overlapping spots in the original carpet pad. Single-visit treatment cleaned everything out.
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 Lake 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 →
“Senior Golden, basement accidents, plug-ins everywhere. AOK fixed it in one visit. The basement smells like a normal room for the first time in over a year.”
“Two big dogs and a great room. The smell was driving me crazy. AOK got it done in one visit. Highly recommend.”
“Bought a home from original owners with a senior cat history. AOK found everything and treated it in one afternoon. Honest people.”

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.
Gurnee is about 50 minutes east of our Algonquin headquarters via IL-22 and IL-21. We batch Gurnee with other Lake County jobs (Grayslake, Antioch, Libertyville) to keep the route efficient. Same-week scheduling is normal and we've been running the corridor for years.
We're about 50 minutes from Gurnee via IL-22 east to IL-21 (Milwaukee Ave) north. 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.
