Quick Cost Reference
Cost by Tier
Minor damage repair - replacing 2-3 damaged floor joists or wall studs, no structural members affected, surface-level cosmetic restoration.
Moderate damage affecting several floor joists, subfloor sections, or wall framing, sistering damaged members, partial flooring replacement.
Extensive damage to structural members, sill plates, rim joists, and subfloor throughout a significant area, requiring engineer assessment and full framing replacement.
How This Calculator Works
This termite damage repair cost calculator estimates your total project cost from four inputs: project size, quality tier, the options you select, and your location. It combines material and labor rates for your chosen tier, adds typical permit costs, then applies a regional cost multiplier so the estimate reflects pricing in your state.
Estimates use 2026 cost data cross-referenced from multiple industry sources. Treat the result as a planning range, not a quote. Your final price depends on your specific scope, material choices, and local contractor availability, so collect at least three itemized bids before you set a budget.
What Affects Your Termite Damage Repair Cost
Extent and Location of Damage
$300 - $60,000+Surface-level damage to window trim or non-structural wood costs $300-$1,000 to repair. Damage to floor joists or wall studs runs $1,500-$8,000 depending on how many members are compromised. Damage to sill plates, rim joists, and girders - the most structurally critical members - costs $5,000-$25,000+. Widespread infestation affecting multiple areas can exceed $50,000 in severe cases.
Type of Termite and Infestation History
$1,000 - $20,000Subterranean termites (most common in the US) damage wood from the inside out, often leaving a thin outer shell. Drywood termites are more common in coastal and Southern states. Formosan subterranean termites - found in the Deep South - are by far the most destructive and can cause catastrophic structural damage in 5-10 years if untreated. Treatment must precede repair.
Structural Member Type
$500 - $25,000Non-structural members like fascia, trim, and decorative wood are cheapest to replace at $100-$300 per piece. Floor joists can be sistered (reinforced alongside) for $200-$600 each. Load-bearing wall studs require temporary shoring during replacement at $1,500-$4,000 per affected section. Damaged sill plates - the wood in direct contact with the foundation - cost $2,000-$5,000 per 10 linear feet to replace.
Access and Demolition Required
$500 - $15,000Damage visible in an open crawl space is the least expensive to access. Damage under a concrete slab or behind finished walls requires demolition first. Removing flooring, drywall, or exterior siding to access damaged framing adds $500-$3,000 in demolition and $2,000-$12,000 in restoration. Crawl space access difficulty adds $500-$2,000 in labor.
Prior Termite Treatment
$1,000 - $5,000 (separate cost)You cannot permanently repair termite damage without first eliminating the infestation. Liquid soil treatment for subterranean termites runs $1,000-$3,000. Fumigation (tenting) for drywood termites costs $2,000-$5,000 for a typical home. Bait stations are $1,000-$2,500 with annual monitoring fees. Repair contractors will not warranty their work unless treatment is documented.

How can I lower my termite damage repair cost?
