Professional Dry Rot Repair in San Jose, CA
Dry rot in exterior wood is a common finding on San Jose’s older homes – particularly in Willow Glen, Rose Garden, and Naglee Park where original wood window sills, fascia boards, and door casings have been exposed to decades of moisture cycling from winter rain. The exterior surface can look painted and intact while the wood underneath has lost most of its structural integrity to fungal decay.
Painting over dry rot without repairing it is one of the most reliable ways to get a short-lived exterior paint job. The new finish bonds to compromised wood fiber, moisture continues to move through the damaged area, and the coating blisters and fails faster than it would on sound wood. The repair has to happen before the paint.

What's Included
- Physical probe inspection of all exterior wood trim, sills, fascia, and at-risk areas
- Epoxy consolidant applied to surface-level rot in otherwise structurally sound members
- Epoxy filler to restore original profile after consolidant has cured
- Full member replacement for structurally compromised fascia, sill sections, or trim pieces
- Recaulking of all repaired joints and penetrations as part of the repair scope
- Primer on all bare and repaired wood before topcoat
- Moisture entry point assessment and recommendations to prevent recurrence
Our Process
1
Probe inspection
Screwdriver or pick testing at all suspect exterior wood areas. Sound wood resists; rotted wood gives way. The extent of rot in each member was documented.
2
Assessment call
Epoxy repair vs. full replacement decision made for each affected member based on depth and extent of rot.
3
Epoxy consolidant
Applied to surface-rot areas in otherwise sound members. Consolidant soaks in and hardens compromised fiber.
4
Epoxy filler
Applied to restore the original profile once the consolidant has cured. Shaped and sanded to match adjacent surfaces.
5
Replacement
Structurally compromised members removed and replaced. All cut ends are primed before installation.
6
Caulk and prime
All repaired joints recaulked; all bare and repaired wood primed.
7
Walk-through
All repair locations are reviewed with the homeowner before painting begins.
Where Dry Rot Concentrates in San Jose Homes
Window Sills
Window sills are the highest-risk areas for dry rot in most San Jose homes. They're horizontal, so water pools rather than runs off. Failed caulk at the window frame joint allows water in. Original wood window sills in Willow Glen and Rose Garden homes have had decades to accumulate that moisture exposure.
Fascia Boards
Fascia boards run along the roofline and support gutters. Clogged gutters in San Jose homes under large valley oaks and sycamores concentrate moisture at the fascia through overflow. Rot here is often hidden behind the gutter until the gutter is removed - we check fascia condition specifically on every exterior estimate.
Door Casings and Corner Trim
Failed caulk at the joint between exterior door casing and the surrounding wall allows moisture to get behind the trim and establish rot over time. We check caulk condition at all exterior trim joints as part of every exterior assessment.
What a Finished Dry Rot Project Looks Like in San Jose
A homeowner in Naglee Park had five window sills with soft spots that had been painted over in previous exterior jobs. After probe testing, three sills received epoxy consolidant and filler repair; two sills required full replacement because the rot had gone through the full thickness of the wood.
After priming all five and painting to match the exterior, the sills were indistinguishable from sound wood. The homeowner said they’d been watching those sills get worse for three years before finally calling.
