Streamwood West Bi-Level — 50-Year Pad
A Streamwood West 1974 bi-level owner had summer odor reactivation for decades. Original pad held layered pet contamination from multiple prior pets. One-visit pad treatment cleared the upstairs bedrooms.
If your Streamwood 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 Streamwood pet owners since 1981.

Streamwood is about 25 minutes east of Algonquin via IL-58 and IL-72, and it's a frequent stop on our Cook County route. The village was largely built out as a mass-produced post-war suburb in the 1960s and '70s, and that's what dominates the housing: block after block of bi-levels, split-levels, and tri-levels on compact lots, with attached two-car garages. A smaller share of 1990s-2000s subdivisions fills in the north and east edges.
The mid-century tract housing drives most of the pet odor work here. A 1972 Streamwood bi-level typically has three bedrooms upstairs with carpet, a lower-level family room with carpet over slab or plywood, and a kitchen-dining combo on the main level. Original carpet pad from that era is still in place under replaced carpet in a surprising number of homes, and layered contamination from multiple generations of pets and owners accumulates there. Summer humidity reactivates it every year.
The lower-level family rooms are the other common Streamwood pattern. When the family room sits on a concrete slab — which is the case in a lot of bi-levels — a senior dog's winter accidents get absorbed into the concrete. Carpet cleanings don't reach it. We treat the slab through the carpet, extract, and the smell stays gone.
Streamwood is close enough to the shop that same-week scheduling is reliable, and we often batch with Hoffman Estates, Bartlett, and Hanover Park stops.
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 Streamwood-area technician arrives in about 25 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 Streamwood homes — with real before-and-after results.

A Streamwood West 1974 bi-level owner had summer odor reactivation for decades. Original pad held layered pet contamination from multiple prior pets. One-visit pad treatment cleared the upstairs bedrooms.

An Oak Ridge home with a senior Lab had lower-level family-room accidents over two winters. Concrete slab was the source. We treated the slab directly and re-extracted the carpet. Zero return.

A young family bought a Highlands tri-level and found cat contamination across two bedrooms. UV mapped eight spots. One visit, pad treatment, all gone.
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 →
“Our 1974 bi-level had a summer smell every year. AOK explained the original pad was holding decades of contamination and treated it. Completely different this summer.”
“Our Lab had destroyed the lower level over two bad winters. AOK treated the concrete and it is back in service.”
“Bought a tri-level, got the cat smell free. AOK fixed two bedrooms in one visit.”

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 — Streamwood bi-level and tri-level homes typically have lower-level family rooms sitting on concrete slabs, and that's a specific pattern we handle regularly. Treating the slab directly through the carpet is what fixes the winter-dog-accident problem that surface cleaning can't reach.
We're about 25 minutes from Streamwood via IL-58 (Lake St) / IL-72 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.
