If your Lake in the Hills 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 Lake in the Hills pet owners since 1981.

Lake in the Hills is right next door to our Algonquin headquarters — about 8 minutes via IL-31 or Algonquin Road. We've been cleaning carpets in LITH for as long as the village has had subdivisions, and most of our current LITH calls come from neighbor-to-neighbor referrals. Word travels fast in a town this size.
The village has two distinct sides for pet odor work. The older "Original Section" near the namesake lake (with the Tree, Indian, and Presidents subsections) has homes from the 1950s-70s with smaller floor plans and tighter lots. Carpet pad in those homes is often original or only once-replaced, and decades of pet history has accumulated. The newer side — Boulder Ridge, Big Sky, Harvest Gate, Spring Lake Farm, and the Randall Road corridor — is dominated by 1990s and 2000s subdivision Colonials with finished basements, attached garages, and the typical synthetic carpet over plywood.
Boulder Ridge is the village's gated community and has a higher concentration of large dogs and multi-pet households. We get more "great room and finished basement" calls from Boulder Ridge than almost any other LITH neighborhood. Our process handles the multi-spot, multi-room jobs in a single visit.
Because LITH is so close to our headquarters, we can usually offer same-day or next-day service for fresh accidents. Animal Hospital of Randall Plaza and Healthy Paws both refer customers to us regularly — the village is small enough that the same names come up over and over.
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 Lake in the Hills-area technician arrives in about 8 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 Lake in the Hills homes — with real before-and-after results.
A Boulder Ridge family with two large dogs had been masking great-room odor 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 homeowner in the Original Section near the lake had a 1962 ranch with a multi-decade cat history. The smell hit them every July. UV showed legacy contamination across both upstairs bedrooms. Single-visit treatment, full pad extraction, and the home smells neutral for the first time.
A Spring Lake Farm family with a 14-year-old Labrador had been managing basement accidents through her last winter. Our blacklight found six spots near the back stairs. Single-visit treatment, full extraction, and the basement is back in service.
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 big dogs in a great room. AOK fixed it in one visit and the smell hasn't come back. They're literally minutes from us and showed up fast.”
“Our 1962 ranch had decades of cat history. AOK got it all out in one visit. Local company, local trucks, local people — that matters.”
“Senior Lab in her last winter. AOK was kind, fast, and professional. The basement smells normal again and the dog passed away in peace.”

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.
