Pet Stain & Odor Carpet Treatment Cost Guide (2026)
💰 Cost Breakdown
| Item | Low | Average | High |
|---|---|---|---|
| Topical enzyme spot treatment (per area) Enzyme pre-spray and extraction on fresh or surface-level accidents. Effective only when urine has not saturated the pad. | $30 | $50 | $75 |
| Sub-surface flush treatment (per room) Enzyme solution flooded into the pad and extracted with a weighted sub-surface tool. The standard fix for odor that returns in humidity. | $75 | $150 | $250 |
| Black-light inspection and odor mapping Identifies every contaminated area, not just the visible ones. Often free with treatment, charged separately as a diagnostic otherwise. | $40 | $100 | |
| Pad replacement with subfloor sealing (per room) Carpet pulled back, contaminated pad cut out and replaced, subfloor cleaned and sealed with odor-blocking primer, carpet re-stretched. | $300 | $700 | $1,500 |
| Whole-room deodorizer or ozone/hydroxyl treatment Air and surface odor neutralization after source removal. A finishing step, not a substitute for treating the pad. | $50 | $125 | $300 |
Topical enzyme spot treatment (per area)
Enzyme pre-spray and extraction on fresh or surface-level accidents. Effective only when urine has not saturated the pad.
Sub-surface flush treatment (per room)
Enzyme solution flooded into the pad and extracted with a weighted sub-surface tool. The standard fix for odor that returns in humidity.
Black-light inspection and odor mapping
Identifies every contaminated area, not just the visible ones. Often free with treatment, charged separately as a diagnostic otherwise.
Pad replacement with subfloor sealing (per room)
Carpet pulled back, contaminated pad cut out and replaced, subfloor cleaned and sealed with odor-blocking primer, carpet re-stretched.
Whole-room deodorizer or ozone/hydroxyl treatment
Air and surface odor neutralization after source removal. A finishing step, not a substitute for treating the pad.
📊 Factors That Impact Cost
Depth of contamination
High ImpactUrine that reached the pad cannot be fixed from the surface. The price difference between tiers is real labor: sub-surface flushing takes several times longer than a topical treatment.
Number of affected areas
High ImpactPer-spot pricing adds up fast. Past four or five areas in one room, whole-room sub-surface treatment is usually cheaper than itemized spots.
Age of the stains
Medium ImpactOld urine crystallizes into salts that re-activate with moisture. Aged contamination needs longer enzyme dwell times and sometimes repeat visits, which some companies build into a higher first quote.
Carpet fiber type
Medium ImpactWool and some nylons hold urine dyes more stubbornly and limit which chemistry can be used safely. Specialty-fiber handling carries a premium.
Subfloor material
Medium ImpactPlywood and OSB absorb urine and must be sealed; concrete usually needs only cleaning. Sealing adds material and dry-time labor to a pad replacement job.
💡 Money-Saving Tips
Ask for a black-light inspection before approving a treatment plan
Paying for spot treatments in two areas while six more sit invisible guarantees a second service call. A full map lets you buy the right treatment once.
Treat fresh accidents immediately yourself
Blotting fresh urine and applying a quality enzyme product within hours keeps most accidents in the cheap surface tier instead of the pad tier.
Combine treatment with a full carpet cleaning
The equipment is already in your driveway. Pet treatment added to a whole-home cleaning is usually discounted versus a standalone odor-only visit with its own trip minimum.
Compare pad replacement against carpet replacement on older carpet
If the carpet is 10+ years old and contamination is widespread, a $1,200 remediation on carpet worth less than that is poor math. Get a replacement quote as a sanity check.
