Termite Damage Repair Cost Calculator

Termite damage repair typically costs $1,000 to $5,000 for a moderate repair, though minor cosmetic repairs can be as low as $250 to $1,000, and significant structural damage can run $3,000 to $8,000 or more — extensive damage to a home's structure can even exceed $10,000 to $30,000+. The cost is driven by the extent of the damage (roughly the square footage of the affected area), the repair type (cosmetic/surface work like drywall and trim ~$12/sq ft, framing/subfloor/joist repairs ~$25/sq ft, and major structural repairs to load-bearing members ~$45/sq ft), the severity (minor localized vs. severe widespread), and the location/access (open, accessible damage is cheaper than damage in a crawl space, attic, or hidden behind finishes that requires demolition to reach). A ~$500 minimum applies. Note that damage repair is separate from termite treatment (killing the termites) — you generally need both, and you should treat first so the new wood isn't eaten too. Add-ons like replacing joists/beams, treatment, subfloor replacement, fixing the moisture source, and a WDO inspection stack on top. Enter your damaged area, repair type, severity, and access above for a localized estimate.

They're two separate services that solve different halves of a termite problem, and you typically need both. Termite treatment (a pest-control service) eliminates the active infestation and protects the home — using liquid termiticide barriers around the foundation, in-ground bait stations to kill the colony, wood injection/foam, or, for severe drywood infestations, whole-house fumigation (tenting). Its job is to kill the termites so they stop causing damage. Termite damage repair (a construction/restoration service) fixes or replaces the wood and structural elements the termites already damaged — framing, joists, subfloor, beams, studs — plus the cosmetic damage to drywall, trim, and paint. Its job is to restore the home's structural integrity and appearance. The order matters: treat the termites first (or at the same time), then repair, because repairing over an active colony means the termites just eat the new wood too. Often a pest-control company handles treatment and inspection while a contractor handles the structural repairs (some firms do or coordinate both). They're separate costs — treatment runs a few hundred to a few thousand dollars, while repair varies widely with the extent of damage. This calculator estimates the repair cost and includes a termite-treatment add-on, since you'll need to eliminate the termites too; a separate termite-treatment calculator covers the extermination side.

The distinction drives the cost, urgency, and safety, but it often takes a professional inspection to judge accurately since termite damage is frequently hidden inside walls and structural members. Cosmetic (non-structural) damage affects surface and finish elements that don't hold up the house — drywall, trim, baseboards, paint, window and door casings, and other non-load-bearing wood. Signs include small holes, blistered or hollow-sounding surfaces, and damaged trim; it's less urgent and cheaper to repair, though it can hint at a bigger hidden problem. Structural damage affects the load-bearing and support elements — floor joists, beams, posts, load-bearing wall studs, the subfloor, roof rafters, and sill plates. It's serious because it can compromise the home's stability, and the warning signs include sagging or springy floors, sticking doors and windows, cracks in walls or ceilings, bowing walls, hollow-sounding structural wood, and visible damage or mud tubes on joists and beams in the crawl space, basement, or attic. Structural repairs are more urgent, more expensive, and may need an engineer's assessment and permits. Because the full extent is usually more than what's visible, a pest inspector, structural engineer, or experienced contractor should probe the wood and sometimes open up walls to assess it. This calculator lets you pick cosmetic/surface, framing/subfloor, or major structural to estimate accordingly — when in doubt, get it inspected.

Generally, no — standard homeowners insurance does not cover termite damage or treatment, because it's considered a preventable maintenance issue rather than a sudden, accidental event. Insurance covers sudden, unforeseen perils like fire, storms, and theft, but it excludes damage from pests and insects, as well as neglect, lack of maintenance, and gradual wear. Termite damage happens slowly over time and is viewed as preventable through regular inspections, treatment, and controlling moisture and wood-to-soil contact, so insurers classify it as the homeowner's responsibility. There are rare, situational exceptions — for instance, if hidden termite damage causes a sudden structural collapse, some policies might cover the collapse itself — but these are often disputed, and the termite damage and treatment are not covered. The practical upshot: you'll typically pay out of pocket for both treatment and repair, which is exactly why prevention (annual inspections, keeping the home dry, and maintaining a treatment barrier) is so cost-effective. Some homeowners carry a termite bond/warranty with a pest-control company that covers re-treatment and sometimes damage if termites return — but that's a separate contract, not homeowners insurance. When buying a home, a termite/WDO inspection helps catch existing damage before you're on the hook for it. This calculator helps you estimate the repair cost you'll likely be paying yourself.

Yes — eliminate the termites before or at the same time as repairing, because repairing the wood while the colony is still active means the termites will just keep feeding and damage your brand-new repairs. Treating first stops the source so the repairs last. The recommended sequence is: get a professional inspection to assess the activity and the extent of damage; eliminate the active infestation with the appropriate treatment (liquid barrier, baiting, wood treatment, or fumigation for severe drywood cases); fix any moisture problems or conducive conditions (leaks, wood-to-soil contact, poor drainage) that attracted the termites in the first place; then repair or replace the damaged wood and finishes; and finally maintain ongoing prevention with a bond or regular inspections. In practice, treatment and repair are often coordinated closely — the termites are eliminated and then the repairs proceed. A pest-control company usually handles the treatment and inspection while a contractor handles the structural and cosmetic repairs, and some firms coordinate both. The key rule is never repair over an active infestation. This calculator estimates the repair cost and includes a termite-treatment add-on, reflecting that eliminating the termites is part of fully resolving the problem — and fixing the moisture source is what keeps them from coming back.

Catching termites early keeps the damage — and the repair bill — small, so it's worth knowing the signs. The clearest indicators are mud tubes (pencil-width tunnels of dirt) running up foundation walls, piers, or in the crawl space, which subterranean termites build to travel from the soil to wood. Discarded wings near windowsills or light sources signal a swarm, and swarming winged termites (which look like flying ants) inside the home point to an active colony. Wood that sounds hollow when tapped, or that's soft, crumbling, or shows a honeycomb/maze pattern inside when probed, indicates termites have been eating it from within. Other tells include frass (drywood-termite droppings that look like small piles of sawdust or coffee grounds), bubbling, peeling, or uneven paint (from moisture and tunneling just under the surface), tight-fitting or sticking doors and windows, sagging or soft floors, and small pinholes in drywall. Because subterranean termites work from the inside out and often in hidden areas, the visible damage is usually less than the actual damage. If you spot any of these, get a professional inspection promptly — the difference between a $500 cosmetic patch and a $10,000 structural repair is often just how long the infestation went unnoticed. A WDO inspection (an add-on here) documents the activity and damage.

It varies widely with the extent and type of damage — minor cosmetic repairs may take a day or two, while extensive structural repairs can take one to several weeks or longer. Repairing surface, non-structural damage (some drywall, trim, baseboards, paint, minor wood) is quick, often a day to a few days of finish work. Moderate repairs — framing, subfloor sections, a few joists, or a moderate damaged area — typically take several days to a couple of weeks, since the crew removes the damaged structural wood, installs new lumber, and then redoes the subfloor, flooring, and drywall on top. Major structural repairs — multiple joists or beams, load-bearing members, large framing areas, or significant reconstruction — can take a week to several weeks or more, involving demolition, structural work (sometimes with temporary supports, engineering, and permits/inspections), rebuilding, and finish restoration. Beyond the repair itself, allow time for termite treatment beforehand — fumigation in particular requires tenting and aeration over a few days — and for any permits, engineering, and inspections that structural work triggers. Hard-to-reach damage (crawl spaces, attics, behind walls) adds demo and access time, and associated moisture or wood-rot repair extends it further. So plan for a day or two on minor jobs up to a few weeks on major structural ones, plus the treatment lead time. Your contractor can give a firm schedule after assessing the damage.

Prevention is far cheaper than repair, and it comes down to removing what attracts termites — moisture and wood-to-soil contact — plus maintaining barriers and inspecting regularly. Control moisture first: fix plumbing and roof leaks promptly, grade the soil and run gutters and downspouts to drain water away from the foundation, and reduce humidity in crawl spaces and basements with ventilation, a dehumidifier, or vapor-barrier encapsulation. A dry home is much less inviting. Eliminate wood-to-soil contact: keep siding, framing, posts, and decks from touching the soil, don't store firewood, lumber, or mulch against the house, and keep mulch a few inches off the foundation and not too deep. Maintain treatment and barriers: keep a liquid termiticide barrier or bait-station system in place and renew it as recommended, and consider a termite bond/warranty with a pest-control company for ongoing monitoring, re-treatment, and sometimes damage coverage. Get regular professional inspections — annually, or more often in high-risk regions — to catch activity before it becomes structural, since early detection dramatically limits the damage and cost. Also reduce conducive conditions: remove dead stumps and roots near the home, seal foundation cracks and gaps around utility penetrations, and keep dense shrubs off the walls. When building or repairing, use pressure-treated or termite-resistant materials near the ground. This calculator estimates repair costs, but consistent moisture control, barriers, and inspections are what help you avoid them entirely.
