If your Roselle 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 Roselle pet owners since 1981.

Roselle is one of those middle-ring DuPage suburbs that built out almost entirely in the 1960s and '70s. The village has a consistent housing profile — single-family ranches and split-levels in the original neighborhoods, with duplexes and townhouses adding to the mix in the 1970s and '80s. Most of the village's homes were built around 1976, give or take a few years, which puts the original carpet pad at roughly 50 years old today.
The most common Roselle call we get is from a family in one of the established Ventura 21 or Parkview neighborhood homes whose senior dog or cat has had accidents in the same room for months or years. Surface cleaning kept the smell manageable until the first humid week of summer reactivated the pad contamination. Our UV inspection finds the actual problem, our process treats it, and the smell is gone for good in one visit.
The other Roselle pattern is finished basements — almost universal in the village's 1970s-80s split-level homes — where dogs that don't want to brave a Chicago winter have had accidents on the carpet over concrete slab. Concrete absorbs uric acid and surface cleaning never reaches it. We treat the slab directly when contamination has reached it.
Roselle is about 36 minutes southeast of our Algonquin headquarters via IL-25 down to Lake Street. Roselle Animal Hospital, Lake Street Animal Hospital, and Park Rose Animal Hospital all refer customers to us regularly. Same-week scheduling is normal.
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 Roselle-area technician arrives in about 36 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 Roselle homes — with real before-and-after results.
A Ventura 21 homeowner had a 17-year-old cat with declining bladder control and a master bedroom that had absorbed years of accidents. UV inspection found four overlapping spots in the original carpet pad. Single-visit treatment, full extraction, and the bedroom smells normal again.
A Parkview family with a 14-year-old Lab had basement accidents that had soaked through to the concrete subfloor. We treated and sealed the affected sections, then extracted the carpet. The basement is back in service.
A new owner inherited cat smell from previous owners. UV showed five overlapping spots across the living room carpet pad. Single-visit treatment cleaned everything out.
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 DuPage 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 →
“Senior cat in her last year, master bedroom accidents. AOK was kind and the smell is completely gone. Wonderful service.”
“Senior Lab, basement concrete problem, two other companies had failed. AOK actually fixed it in one visit.”
“Bought a home with an undisclosed cat history. AOK found everything and the smell hasn't come back.”

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 — Roselle's 1970s-80s split-level homes almost universally have finished basements with carpet over concrete. When contamination has reached the slab, we treat and seal the concrete directly. Most basement jobs are completed in one visit.
We're about 36 minutes from Roselle via IL-25 to Lake Street 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.
