Smoke Damage Cleanup Cost Calculator
Price a smoke & soot cleanup from the area affected, the cleaning rate on your quote and the cost of sealing surfaces to lock in residual odor.
Calculator
Cleaning smoke damage over 600 sq ft at $6.00/sq ft plus $500.00 of sealing is about $4,510.00. Sealing surfaces with a stain-blocking primer locks in residual odor. Enter your quoted price; a planning estimate, not a bid.
Smoke damage is deceptive: the fire may have been small and contained, yet smoke and soot travel through the whole house, staining surfaces and leaving an odor that returns every time the humidity rises. Cleaning it is a labor job priced by the area treated, plus the cost of sealing porous surfaces so the smell does not bleed back through fresh paint.
This calculator estimates that cleanup from the rate on your own quote — no national price is baked in. It is the companion to the fire damage restoration tool when the structure is intact but the smoke went everywhere.
Formula
The estimate is a simple, transparent identity:
total = (affected_sqft × $/sq ft + sealing) × (1 + contingency%)
- affected_sqft × $/sq ft — the cleaning labor over the smoke-affected area.
- + sealing — stain-blocking primer/sealer that locks residual odor into the substrate.
- × (1 + contingency%) — a 5–20% buffer for residue hiding in cavities, ductwork and porous contents.
The rate is a price you enter; the tool never invents one.
Worked example
Suppose smoke reached 600 sq ft of walls and ceilings. Your cleaner quotes $6/sq ft and $500 to seal the affected surfaces, with a 10% contingency:
(600 × $6 + $500) × 1.10 = ($3,600 + $500) × 1.10 = $4,510
Sealing looks optional until you skip it: without a stain-blocking primer, wet-smoke odor commonly comes back through new paint within weeks — a re-do that costs far more than the $500 line.
Dry, wet and protein smoke
Not all smoke is the same. Dry smoke from a hot, fast fire leaves a powdery soot that often dry-sponges off. Wet smoke from a slow, smoldering fire leaves a sticky, smeary residue with a strong odor that clings to everything and frequently requires replacement rather than cleaning. Protein smoke (from a kitchen fire) is nearly invisible but discolors finishes and carries an intense smell. The rate you enter should reflect which one you are dealing with.
Odor is the part homeowners underestimate. Cleaning the visible soot is only half the job; the smell hides in wall cavities, insulation, HVAC ducts and soft contents. That is why professionals seal cleaned surfaces and often run air scrubbers or thermal fogging — see the soot & odor removal and air scrubber / negative-air CFM tools for those lines.
Two areas are worth a dedicated line on your quote. The HVAC system pulls smoke through the whole house and then re-circulates the odor every time it runs; having the ducts cleaned after a fire is often the difference between a smell that fades and one that lingers — price it with the air duct cleaning cost tool. And soft contents — upholstery, drapes, clothing, mattresses — absorb odor deeply; some are cleaned on-site, others are packed out for specialist treatment or written off as non-restorable, which shifts cost from this cleanup line to a pack-out or your contents claim.

Reference table
Typical planning bands for the labor-and-materials rate — a sanity guide only. Enter the rate from your own written quote; costs vary with severity, materials, access and local labor.
| Work type | Typical $/sq ft (labeled band) | What drives it |
|---|---|---|
| Structural fire damage | $15–$40/sq ft | Char depth, framing/drywall replacement, severity multiplier |
| Smoke & soot cleaning | $3–$8/sq ft | Residue type (wet vs dry smoke), surface area, sealing |
