Fire Damage Restoration Cost Calculator
Estimate what it costs to restore a fire-damaged area from the price per square foot on your quote, a severity factor and the structure & contents line items — then add a contingency buffer.
Calculator
Restoring 500 sq ft of fire damage at $25.00/sq ft (1.00× severity) plus $2,000.00 of line items is about $15,950.00. Structural fire damage varies enormously with severity — enter your quoted price. A planning estimate, not a bid.
House fires rarely burn a whole home — but they touch far more than the flames reach. Between the char, the smoke that migrates through the structure, and the water used to put the fire out, restoration is a multi-trade job. This calculator gives you a planning number for the restoration line so you can sanity-check a contractor’s estimate before you sign.
It works the way a real scope of work is priced: a base cost of affected area × rate, scaled by a severity factor (light surface soot behaves very differently from heavy structural burns), plus the big line items — framing, drywall, contents cleaning and debris removal — and finally a contingency for the damage nobody sees until the burnt materials come out.
Formula
The estimate is a single closed-form identity:
total = (affected_sqft × $/sq ft × severity + line_items) × (1 + contingency%)
- affected_sqft × $/sq ft — the base restoration cost of the burned area.
- × severity — 1.0× light/surface, 1.5× moderate, 2.0× heavy/structural. A labeled planning multiplier you can override.
- + line_items — structure and contents work priced separately on your quote.
- × (1 + contingency%) — a buffer (5–20%) for hidden damage.
Every dollar figure is a price you enter from your own bid — the tool holds no restoration price of its own.
Worked example
Say a fire damaged 500 sq ft of a home. Your contractor quotes $25/sq ft for the restoration work, the damage is light/surface (severity 1.0×), and structure-and-contents line items add $2,000. With a 10% contingency:
(500 × $25 × 1.0 + $2,000) × 1.10 = ($12,500 + $2,000) × 1.10 = $15,950
Bump the severity to heavy/structural (2.0×) and the base doubles to $25,000, pushing the total to about $29,700 — which is exactly why the severity of the burn, not just the square footage, drives a fire estimate.
How fire restoration is scoped
Fire restoration typically runs in three overlapping phases. First, emergency board-up and water extraction stops further loss (the water used to fight the fire is itself a Category 2/3 water problem — see the water damage restoration cost tool). Second, structural repair — removing and rebuilding charred framing, drywall, insulation and flooring. Third, smoke, soot and odor removal, which is often the most stubborn part because smoke penetrates cavities and porous materials far from the burn.
Two things make fire estimates swing wildly. One is severity: dry-smoke soot from a fast, hot fire wipes off many surfaces, while wet-smoke residue from a slow, smoldering fire smears and requires replacement. The other is hidden damage — heat warps materials and smoke travels through the HVAC system and wall cavities, so the true scope only appears once demolition begins. That is what the contingency line is for.
Sequence matters, too. Reputable restorers stabilize the property first (board-up, tarping, water extraction), then let the structure dry and the smoke settle before pricing the full rebuild — which is why an early “total” number is really a range, not a fixed bid. Timelines commonly run from a couple of weeks for a contained kitchen fire to several months for a whole-structure loss, and the longer the job runs, the more the ancillary lines (storage, temporary housing, repeated deodorizing passes) add up. Building this into your planning number up front prevents sticker shock later.
This is a budgeting estimate, not a bid or an insurance valuation. Fire claims are usually handled through your homeowner’s policy; use the insurance out-of-pocket estimator for the deductible math, and confirm coverage with your insurer/adjuster.

| 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 |
