If your Round Lake 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 Round Lake pet owners since 1981.

Round Lake is about 30 minutes east of Algonquin via IL-134 and Fairfield Road. The broader Round Lake area — which includes Round Lake Beach, Round Lake Heights, and Round Lake Park — has some of the widest housing variety in our Lake County service area, and each era brings a different pet odor pattern.
The oldest homes are the 1920s-60s lakefront cottages around Round Lake itself. Many were originally summer homes, later converted to year-round use. These often sit on wood subfloors over crawl spaces or partial slab foundations, and cat urine in particular tends to migrate into the wood. Summer humidity brings the smell back every year until the subfloor is treated and sealed.
The mid-century homes in the central grid neighborhoods follow the typical post-war pattern: 1960s-70s ranches and splits with original carpet pad still present under replaced carpet. Layered pet contamination across multiple owners is common. Pad treatment clears it.
The 1990s-2010s subdivisions like Valley Lakes, Meadowview, and The Lakes of Round Lake Beach are newer Colonials and Craftsmans with finished basements on concrete. Senior-dog winter accidents in the basement are the main pattern. Treating the slab through the carpet is what fixes it.
Round Lake is a regular stop on our Lake County route — same-week appointments are reliable.
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 Round Lake-area technician arrives in about 30 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 Round Lake homes — with real before-and-after results.
A Round Lake Beach cottage from 1947 had a persistent cat smell in two rooms. Wood subfloor under successive carpets held the urine. We pulled the edges, treated and sealed the wood, and re-laid. Smell gone.
A Valley Lakes family with a senior Lab had winter basement accidents. Concrete slab was the source. We treated the slab directly and re-extracted the carpet. Zero return.
A Meadowview home with a new Lab puppy had multiple accidents in a master bedroom before housebreaking was complete. UV found four spots. Single-visit pad treatment, clean.
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 →
“Our cottage had smelled off every summer since we bought it. AOK treated the wood under the carpet and it is finally fresh.”
“Our Lab had ruined the basement. AOK treated the concrete and it is back in service.”
“New puppy, minor disaster. AOK fixed it in one visit. Totally worth it.”

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.
We serve all of them — Round Lake, Round Lake Beach, Round Lake Heights, and Round Lake Park. They share geography and we treat them as one service area on our route. Same-week scheduling is normal and we can usually batch with Grayslake or Antioch stops.
We're about 30 minutes from Round Lake via IL-134 / Fairfield 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.
