Termite Damage Repair Cost Estimator
Estimate your termite damage repair costs based on the affected area, severity of damage, wood type, and regional labor rates.
Formula
Effective Area = Affected Area (sq ft) × Severity Factor
• Light = 0.30 | Moderate = 0.65 | Severe = 1.00
Material Cost = Effective Area × Material Rate ($/sq ft)
• Softwood $3.50 | Hardwood $7.00 | Engineered $9.50 | Treated $5.00
Labor Cost = Area × $6.00 × Severity Labor Premium × Location Factor × Regional Index
• Severity Premium: Light 1.00× | Moderate 1.25× | Severe 1.60×
• Location Factor: Subfloor 1.30× | Wall 1.20× | Roof 1.50× | Trim 0.80× | Deck 1.10×
Disposal Cost = Effective Area × $0.50
Repair Subtotal = Material + Labor + Disposal
Contingency = Repair Subtotal × 10%
Treatment Cost (optional) = Area × $2.50 × Regional Index
Total Cost = Repair Subtotal + Contingency + Treatment Cost
Estimated Range = Total × 0.80 (low) to Total × 1.20 (high)
Assumptions & References
- Material costs are national averages per RSMeans Building Construction Cost Data (2024) and Angi/HomeAdvisor cost guides.
- Base labor rate of $6.00/sq ft reflects a licensed carpenter; actual rates vary by contractor and market.
- Severity factors estimate the proportion of wood requiring full replacement vs. surface repair.
- Location complexity multipliers account for access difficulty, ancillary work (drywall, flooring removal), and safety requirements.
- Regional index sourced from U.S. Bureau of Labor Statistics regional wage differentials and local contractor surveys.
- Termite treatment cost of $2.50/sq ft is an average for liquid termiticide barrier or bait station systems (NPMA, 2023).
- A 10% contingency is standard practice for renovation projects with hidden damage potential.
- Estimates do not include permits, inspections, painting/finishing, or mold remediation if present.
- Always obtain at least three quotes from licensed pest control and general contractors before proceeding.
- Costs reflect 2024 USD; adjust for inflation in subsequent years.
