If your Arlington Heights 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 Arlington Heights pet owners since 1981.

Arlington Heights is one of the most stable, well-kept suburbs in our service area, but the housing stock tells a specific story when it comes to pet odor. The vast majority of single-family homes in Arlington Heights were built between 1950 and 1975 — ranches in Arlington Highlands and Arlington Manor, split-levels and bi-levels in Surrey Ridge, Colonial Revivals throughout Greenbrier and Laudymont Terrace, and Cape Cods near downtown. That means the carpet pad we're often treating is the original from the era when the house was built. It's been there for 40, 50, sometimes 60 years.
Original carpet pad isn't necessarily bad — but it's a sponge. Every accident from every pet that's lived in the home gets absorbed into the foam, and unless someone has actually treated the pad (not just the carpet), that history is still there. We routinely show Arlington Heights homeowners spots they didn't know existed because previous owners had pets and the smell only reactivates on humid days.
The other Arlington Heights pattern: finished basements. Heritage Park, Catino Estates, and the older Arlington Highlands homes almost all have finished family rooms downstairs, and that's where dogs that don't want to go out in a Chicago February tend to have accidents. Concrete subfloors don't show the problem visually but they hold uric acid for years.
Our process treats both layers — the pad in the upstairs bedrooms and living rooms, and the concrete or wood subfloor in finished basements. Most Arlington Heights jobs are one visit, and Arlington Heights is close enough to our Algonquin headquarters (about 32 minutes east on IL-62) that we can handle same-week scheduling reliably.
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 Arlington Heights-area technician arrives in about 32 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 Arlington Heights homes — with real before-and-after results.
A Surrey Ridge family bought a 1968 split-level and the smell hit them the first humid week. UV inspection showed multiple legacy contamination zones in the upstairs bedrooms — clearly from a previous owner's cats. The original carpet pad was still in place. We treated the pad through the carpet, dwelled, and extracted. The owner sent us a thank-you text two weeks later about the difference.
An Arlington Manor home with a senior Golden Retriever had accumulated winter accidents on the basement family-room carpet over two seasons. Concrete subfloor was holding the contamination. We treated and sealed the affected concrete sections, then re-extracted the carpet above. Six-month follow-up: zero smell return.
A Catino Estates ranch had been through four owners over 30 years, and at least two of them had pets. The new family inherited a layered odor problem. Blacklight mapping found nine overlapping spots across the master bedroom and hallway. Treatment took most of an afternoon but cleaned out three decades of inherited contamination. The home smells neutral for the first time in the family's memory.
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 bought a 1965 ranch and the cat smell from the previous owner became unbearable in the summer. AOK found spots we couldn't even see and the treatment worked. Wish every contractor was this competent.”
“Honest, professional, and they actually do what they say. Our basement smell is completely gone after one visit. The technician walked us through everything and didn't try to upsell.”
“Moved into a Catino Estates home with a 30-year history of pets. The smell was layered and complicated. AOK handled it in one visit and the difference is night and day.”

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 — we cover all of Arlington Heights, from the older neighborhoods near downtown out through Surrey Ridge, Catino Estates, and the Heritage Park area. We're about 32 minutes east of Arlington Heights via IL-62 (Algonquin Road), so same-week scheduling is normal and we run the corridor several days a week.
We're about 32 minutes from Arlington Heights via IL-62 (Algonquin Road) 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.
