Home › Pet stain & odor removal
If your carpet was cleaned and the dog smell came back a week later, the last company cleaned the surface. The odor lives in the pad. We find every spot with a UV lamp, treat below the carpet, and tell you honestly — before you pay — which spots a clean can fix and which can’t.
This is the complaint we read over and over in Tampa reviews, and the explanation is chemistry, not bad luck.
Urine goes through the carpet in seconds. It spreads out in the pad — a spot the size of a coffee cup on top is a dinner plate underneath — and often reaches the slab or subfloor. As it dries it leaves uric acid crystals and salts. Those salts are hygroscopic: they pull moisture out of the air. In Tampa, the air has plenty to give.
So a surface clean removes the visible stain, the “clean carpet smell” lasts a few days, and then the first humid afternoon rehydrates the salts in the pad and the odor is back. Deodorizer sprayed on top does nothing about it. That’s not a cleaning failure; it’s a cleaner who never went below the surface.
We wrote a longer explanation here: why the pet smell came back after your carpet was cleaned.
The walk-through decides this, not the phone call. We bring a UV lamp and a moisture meter to every pet job and show you what we find before we quote.
Fresh accidents or a few light spots that haven’t reached the pad. Enzyme pre-treatment, dwell time, hot water extraction with an acid rinse to dissolve the salts. Included in a normal carpet clean with a small per-spot charge.
Typical: puppy training, one-off accidents, a spot caught the same day.
The UV lamp shows spots larger underneath than on top, and the smell is obvious at floor level. We flood the area with enzyme solution to saturate the pad, let it work, then extract it with a sub-surface tool that pulls from the pad instead of the pile. Often two passes.
Typical: “the smell came back after the last cleaning”, older dogs, one favorite corner.
Years of use, cats, or a room that was closed up. The pad is saturated and the slab or wood underneath has absorbed it. Honest answer: cleaning improves this but doesn’t finish it. The fix is to pull the carpet, replace the pad, seal the subfloor, and re-lay. We quote it, or tell you it’s time for new carpet.
Typical: rental turnovers, inherited houses, a cat that was never fully trained.
Usually Level 1 or 2 and usually fully fixable. The exception is a spot used repeatedly for a year or more, which drifts into Level 3.
Stronger, more concentrated, and cats return to the same place. Expect Level 2 minimum. Spraying on walls and baseboards needs treating too or the room still smells.
Old urine bleaches carpet dye. The smell goes; the yellow patch may not. We show you under the lamp so there’s no surprise afterwards.
Same chemistry, different tool. Cushions with removable covers are easier; fixed-cushion sectionals with urine in the foam are quoted honestly — sometimes foam replacement wins.
Urine in a wool rug needs a full immersion wash off-site. See rug cleaning.
Pet treatment is added to a standard room clean. Nothing is added until you’ve seen the lamp.
| Treatment | From |
|---|---|
| Level 1 — per spot, with room clean | $35 |
| Level 2 — sub-surface flood & extract, per area | $85 |
| Level 2 — whole room saturation | $150 |
| Level 3 — pad replacement & subfloor seal | Quoted on site |
| Upholstery pet treatment, per piece | $45 |
Rental units push the urine deeper and wider into the pad with weak vacuum to pull it back. Every rental-machine attempt makes our job larger.
Fragrance masks for a day. Vinegar can set some dyes and does nothing to uric acid. Baking soda left in the pile just clogs the fiber.
White towel, press, don’t rub. Repeat with clean water. Then call us — same-day for fresh accidents when we can.
A cheap UV flashlight (365nm) shows urine as pale yellow-green splotches. Count them so you can tell us roughly how many areas there are.
If it smells at carpet level but not standing up, it’s probably pad. If it smells everywhere including near the baseboards, tell us — that’s usually cat spray and we treat the walls too.
Small items and anything under beds. We move the furniture.
What to do in the first ten minutes, what makes it worse, and how each carpet fiber behaves.
Tell us the rooms and the fiber and we'll quote it on the phone in a couple of minutes. Same-day slots most weekdays.
