If your Des Plaines 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 Des Plaines pet owners since 1981.

Des Plaines sits along the Des Plaines River about 38 minutes east of our Algonquin headquarters via Algonquin Road, and most of the city's single-family housing tells a single story: post-war, 1950s-60s, ranch or split-level, original carpet pad underneath. That's the exact era of housing where pet odor problems hide in the layer between the carpet you can see and the subfloor you can't.
A typical Des Plaines call sounds like this: a family has been in a 1960s ranch for ten or twenty years, their current dog or cat is fine, but something about the way the house smells on humid days has started bothering them. When we get out with the UV light we usually find contamination from one or two previous pets, often going back decades. The original pad has absorbed every accident that was surface-cleaned but never extracted.
The second Des Plaines pattern is flood-related. The Des Plaines River floods, and homes along the river corridor and in Cumberland have had basement water events. When urine contamination combines with moisture history, concrete subfloors develop a particular kind of stubborn odor that requires treating the slab directly, not just the carpet. We see a handful of these every year.
Des Plaines is a common stop for us — close to the O'Hare corridor where we run several days a week — so scheduling is usually easy. Same-week appointments are the norm, and if you're near the Algonquin Road / IL-62 corridor we can often slot you in around an Arlington Heights or Mount Prospect job the same day.
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 Des Plaines-area technician arrives in about 38 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 Des Plaines homes — with real before-and-after results.
A Cumberland homeowner had owned her 1964 ranch since 1992 and had a cat, two cats, and a dog across those years. Summer humidity brought the smell back every year. UV showed four legacy zones. Single-visit pad treatment. Full summer since with no reactivation.
A Riverside home that had been through a minor basement flood years earlier had a dog-urine smell that never fully cleared after. We treated the concrete slab directly through the carpet, sealed two small zones, and the family room is back in service.
A young family moved into a 1968 Rand Park split-level and the upstairs bedroom smelled like cat the first warm week. Prior owners had multiple cats. One visit found and treated six spots in the master bedroom carpet pad.
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 →
“We have had the same ranch since the '90s and every summer the smell came back. AOK finally explained it was in the original pad, treated it, and we haven't smelled it this summer for the first time in years.”
“Basement had pet and water history. Three other companies couldn't fix it. AOK treated the concrete, not just the carpet, and we can finally use that room again.”
“Bought a split-level and found a cat smell the first hot day. AOK was fast, honest, and it's completely gone.”

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.
Des Plaines is about 38 minutes east of our Algonquin headquarters via IL-62. We run the Algonquin Road corridor several days a week, so same-week scheduling is normal and fresh-accident emergencies can often be worked in around existing Arlington Heights or Mount Prospect stops.
We're about 38 minutes from Des Plaines via IL-62 (Algonquin Rd) 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.
