Most wood rot repairs in Houston cost $300–$2,500 in 2026. A single window sill or a short run of trim sits at the low end; long sections of fascia, siding or columns sit at the high end. The repair should replace or rebuild the rotted wood, prime it on all sides, fix the moisture source, and paint it so it matches the house.

Pricing is provided for general planning only and is not a final quote. Final pricing depends on paintable surface area, preparation, repairs, ceiling height, trim, doors, number of colors, paint products, access and project conditions. Houston Superior Painting provides a written estimate for the final scope and price.
Where rot shows up on Houston homes
- Window sills and the bottoms of window and door trim
- Fascia boards under gutters that overflow
- The bottom boards of wood siding and trim near the ground
- Porch columns, posts and railings
- Garage door trim and frames
What moves the price
- How far it goes: rot is often larger than it looks; the soft wood is probed and cut back to sound material.
- Replace or rebuild: badly rotted boards are replaced; small areas can sometimes be rebuilt with a wood epoxy.
- Profile and height: custom trim profiles and second-story fascia take longer.
- The cause: a leaking gutter, missing flashing or failed caulk has to be fixed or the rot returns.
- Paint: new wood is primed on all sides and painted to match.
Fix rot before you paint
Paint over rotted wood hides the damage while it spreads, and the new paint fails within a season or two. That is why rot repair is part of exterior prep and priced line by line in the estimate. See our wood rot repair page and the exterior painting prep guide.

How much does wood rot repair cost in Houston?
Most jobs run $300–$2,500 in 2026, depending on how far the rot goes, the trim profile and the height.
Why does wood rot so often in Houston?
Humidity, heavy rain and long wet periods keep exposed wood damp, especially where gutters overflow or caulk has failed.
Do you replace the wood or fill it?
Badly rotted wood is replaced. Small, contained areas can sometimes be rebuilt with a wood epoxy.
Can you repair the rot and paint in the same project?
Yes. Rot repair is part of exterior prep and is listed in the painting estimate.
