The Cost of Structural Repair from Termites

How Much Does Termite Damage Repair Cost?

The cost of repairing termite damage can vary considerably. Replacing a damaged piece of exterior trim is very different from repairing rafters, fascia boards, floor joists, headers, or other structural components.

For that reason, it is usually impossible to provide an accurate repair price until the damaged areas have been inspected.

What Affects the Cost of Termite Damage Repairs?

Several factors determine the final cost.

Extent of the Damage

Small, isolated areas generally cost less to repair than damage affecting several parts of a building. However, termite damage is not always fully visible from the surface. Additional damage may sometimes be discovered after a damaged board or covering material is removed.

Type of Wood or Building Component

The cost will depend partly on what must be repaired or replaced. Common termite-damaged components include:

• Fascia boards
• Rafters and rafter tails
• Roof sheathing
• Headers
• Patio covers
• Window and door trim
• Siding
• Subflooring and floor joists

Decorative or custom-sized wood may cost more to replace than standard lumber.

Accessibility

Damage located at ground level is generally easier to repair than damage in an attic, crawl space, beneath a deck, or high along a roofline. Difficult access may require additional labor, ladders, scaffolding, or the temporary removal of nearby materials.

Structural Versus Cosmetic Damage

Some termite damage affects only trim or another nonstructural component. Other damage may weaken wood that supports part of the building.

Structural repairs may require additional labor and more extensive replacement. In serious cases, further evaluation may be necessary before the repair method can be determined.

Painting and Finishing

Exterior wood repairs may also require priming, painting, or sealing. Although an existing paint color can usually be closely matched, an exact match cannot always be guaranteed because older paint changes as it is exposed to sunlight and weather.

Can Termite-Damaged Wood Always Be Repaired?

The proper approach depends on the condition and function of the wood.

Some damage can be repaired by removing the affected section and installing new material. In other situations, the entire board or structural component may need to be replaced. Wood fillers and surface patches may improve appearance, but they are not appropriate substitutes when the wood has lost its strength.

A termite inspection helps identify visible damage and determine which areas require attention. However, because inspections are generally limited to accessible areas, concealed damage may not be discovered until repair work begins.

Should Termites Be Treated Before the Wood Is Repaired?

Termite treatment and wood repairs should be coordinated carefully. Simply removing damaged wood may not eliminate termites elsewhere in the structure.

The appropriate treatment depends on the type and extent of the infestation:

• Drywood termites may be addressed with a localized treatment or whole-structure fumigation.
• Subterranean termites generally require treatment involving the soil, foundation area, or a baiting system.
• Damaged or infested wood may also be removed and replaced when appropriate.

The treatment recommendation should be based on an inspection rather than the appearance of the damaged wood alone.

How Can Homeowners Reduce the Risk of Future Damage?

No preventive measure can guarantee that a home will remain termite-free, but several steps can reduce conducive conditions:

• Repair plumbing and roof leaks promptly.
• Maintain proper drainage around the foundation.
• Avoid direct contact between structural wood and soil.
• Remove scrap lumber and buried wood from around the building.
• Store firewood away from the house.
• Keep exterior wood properly painted or sealed.
• Arrange a professional inspection if you find pellets, discarded wings, mud tubes, or suspicious wood damage.

UC Integrated Pest Management generally recommends termite inspections every three to five years. Homes with previous infestations or newly discovered evidence may need to be inspected sooner.
