If your Cary 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 Cary pet owners since 1981.

Cary is one of our closest neighbors — about 14 minutes north of our Algonquin headquarters via IL-31 and IL-14. We've been cleaning carpets in Cary for so long that most of our calls are referrals from previous customers or their neighbors. The village is small enough that word travels fast about who actually fixes a problem versus who just covers it up.
Cary's housing is dominated by 1980s and '90s subdivision construction — Greenfields, West Lake, Foxford Hills, and Maple Hills are all that era — with a smaller stock of older homes near downtown Cary Junction and the Fox River-adjacent Trout Valley area. Most of the homes have synthetic carpet over plywood subfloor, finished basements, and the typical pet-history pattern: a senior dog or repeat-offender cat, accidents in the same spot for months, surface cleaning that didn't work.
The Trout Valley homes are an exception. That older lakefront area has homes with crawl spaces under the living rooms, and pet urine that gets into the pad can wick down into the crawl space and create a smell that surface cleaning will never reach. Those are the jobs where our process makes the biggest difference — we treat the pad, treat the underside if needed, and pull the dissolved urine out completely.
Same-week scheduling is normal for Cary jobs and we routinely handle fresh-accident calls within 24 hours. Cary Grove Animal Hospital and The Animal Doctor both refer customers to us when their patients have 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 Cary-area technician arrives in about 14 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 Cary homes — with real before-and-after results.
A Foxford Hills 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 — the dogs' "too late to make it outside" zone. Single-visit treatment, full pad extraction, and the smell hasn't returned through a full summer.
A Trout Valley homeowner had a persistent cat smell in the living room that no carpet cleaning had fixed. The home was built over a crawl space and the urine had wicked down into the floor joists. We treated the carpet and pad, then addressed the underside through the crawl space access. Single-visit fix, smell gone for good.
A new owner of a Greenfields ranch found cat smell in the master bedroom from previous owners with multiple cats. UV showed five overlapping deposits. One visit, full extraction, and the bedroom is finally usable as a sleeping space.
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 McHenry 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 →
“Two dogs and a great room — I was about to replace the carpet. AOK saved it for a fraction of the cost and the smell is completely gone. Best money I've spent on this house.”
“Our crawl space was holding the smell from cat urine that had soaked through. Other companies couldn't even diagnose it. AOK figured it out and fixed it in one visit.”
“Bought a home with a previous-owner cat history. AOK found way more contamination than I'd been told about. Fixed everything in one afternoon and the smell hasn't come back.”

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 — the older homes in Trout Valley and around the Fox River often have crawl spaces under the living areas, and pet urine can wick down into the floor joists. Our process treats the carpet and pad, and we address the underside through the crawl space access when needed. Most of these jobs are completed in one visit.
We're about 14 minutes from Cary via IL-31 north then IL-14 east. 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.
