If your Algonquin 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 Algonquin pet owners since 1981.

Algonquin is home base for us. Our headquarters is at 1129 W Algonquin Road, and we've been cleaning carpets for Algonquin families since 1987. Anyone who's lived here a while has probably driven past our trucks loading in the morning. That familiarity matters when it's time to call someone about a problem in your home — you're not gambling on a stranger from a Google search. You're calling the people you've already seen around the village.
Algonquin's housing stock makes for an interesting mix of pet odor jobs. Old Town along the Fox River has homes that go back to the early 1900s — narrow lots, hardwood floors downstairs, smaller carpeted bedrooms upstairs, and original lath-and-plaster walls. Pet accidents in those homes tend to be concentrated and easier to trace. Out in Far West Algonquin and the Manchester Lakes / Spring Creek subdivisions, the homes are 1990s and 2000s builds with synthetic carpet over plywood subfloor — bigger great rooms, more open floor plans, and usually a finished basement where dog accidents tend to accumulate over a winter.
Both housing types have one thing in common: when a pet has been going in the same spot for more than a year or two, the urine has reached the pad. Our 7-step process is built to find every spot with a UV blacklight, treat down to the contamination layer, and extract the dissolved crystals — not mask them. Because we're local, our technician can usually be at your door in under 15 minutes if there's a fresh accident before company comes over. Same village, same phone number since 1987.
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 Algonquin-area technician arrives in about 5 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 Algonquin homes — with real before-and-after results.
A century-old home in Old Town Algonquin had a small upstairs bedroom that had been a previous owner's cat's territory. The carpet was new but the original pine subfloor underneath had absorbed years of urine. We pulled back the carpet edge, treated and sealed the wood subfloor directly, and re-laid the carpet. The smell that the new owners had been masking with plug-ins for a year was gone in one visit.
A Manchester Lakes family had a 14-year-old retriever who had been having accidents in their finished basement family room throughout the winter. UV mapping showed five distinct deposit zones. We treated the pad in each, dwelled, and extracted with our truck-mounted system. The carpet was walkable in three hours and the smell hasn't returned through a full summer.
A Far West Algonquin home with three indoor cats had developed a strong odor in the great room that the homeowner couldn't trace. Our blacklight inspection found seven spots over an area she'd thought was clean. Single-visit treatment, full extraction, and a follow-up walk-through two weeks later confirmed zero residual smell.
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 →
“These guys are local — my neighbors have been using them for years. Showed up on time, found the spots in five minutes with the UV light, and the carpet was dry that afternoon. Highly recommend.”
“We had a senior dog issue in our basement that two other companies had failed to fix. AOK came out, treated it once, and it's been gone for nine months. Best money we've spent on the house.”
“Honest, fast, and they didn't try to upsell us anything we didn't need. They told us one spot was minor and could wait, and treated only the areas that mattered. Genuinely good 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.
