Water Damage Restoration Cost Estimator

Estimate the total cost of water damage restoration based on affected area, water damage category, material types, and required services.

Affected Area (square feet)

Water Damage Category

Category 1 – Clean Water (burst pipe, rain) Category 2 – Grey Water (appliance overflow, toilet overflow without feces) Category 3 – Black Water (sewage, floodwater)

Water Damage Class (extent of moisture absorption)

Class 1 – Minimal absorption (part of one room) Class 2 – Significant absorption (entire room, carpet, walls) Class 3 – Greatest absorption (ceilings, walls, floors, insulation) Class 4 – Specialty drying needed (hardwood, plaster, concrete)

Primary Flooring Type

Carpet Hardwood Tile / Vinyl Concrete / Slab

Wall / Ceiling Damage

None Minor (surface only) Moderate (drywall replacement needed) Severe (structural damage)

Mold Remediation Required?

No Yes – Minor ( Yes – Moderate (10–100 sq ft) Yes – Extensive (> 100 sq ft)

Contents Restoration / Pack-Out?

No Yes – Basic (furniture drying) Yes – Full pack-out and restoration

Emergency / After-Hours Service?

No – Standard hours Yes – Emergency / after-hours

#### Formula

Drying Cost = Area × $3.75 × Category Multiplier × Class Multiplier

Flooring Cost = Area × Flooring Rate/sq ft (Carpet $5.50 | Hardwood $12.00 | Tile $7.00 | Concrete $2.50); Class 1 / Cat 1 = 30% of rate (cleaning only)

Wall Cost = Area × Wall Rate (None $0 | Minor $0.80 | Moderate $3.50 | Severe $7.50)

Mold Cost = Minor: $1,000 flat | Moderate: $3,000 + $5 × (area − 10) | Extensive: $5,000 + $8 × (area − 100)

Contents Cost = Area × $0.75 (basic) or Area × $2.50 (full pack-out)

Emergency Surcharge = Drying Cost × 25% (if after-hours)

Total = (Drying + Flooring + Wall + Mold + Contents + Emergency) × 1.15 (overhead & profit)

Range = Total × 0.80 to Total × 1.20

#### Assumptions & References

Water damage categories (1–3) and classes (1–4) follow IICRC S500 Standard for Professional Water Damage Restoration.
Base extraction and drying rate of $3.75/sq ft reflects national averages per HomeAdvisor, Angi, and Xactimate pricing guides (2023–2024).
