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 |
Average Total Cost: $30–$75 per spot for light treatment; $75–$250 per room for pad-level treatment; $500–$1,500 for pad replacement and subfloor sealing
Factors That Impact Cost
Depth of contamination
Urine 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
Per-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
Old 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
Wool and some nylons hold urine dyes more stubbornly and limit which chemistry can be used safely. Specialty-fiber handling carries a premium.
Subfloor material
Plywood 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. Potential savings: $100–$300
- 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. Potential savings: $50–$200 per accident
- 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. Potential savings: $75–$150
- 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. Potential savings: $500–$1,000
