Dry Rot Repair on the Eastside
Structural and cosmetic dry rot removal, backing replacement, and finish-ready restoration for Kirkland, Sammamish, Redmond, Bellevue, and surrounding Eastside homes.
What We Do
The Pacific Northwest's wet climate makes dry rot one of the most common repair issues in Eastside homes. Window sills, exterior door frames, deck ledgers, and areas around roof penetrations are the most vulnerable — and dry rot that goes unaddressed spreads into structural framing faster than most homeowners expect.
We assess the full extent of affected wood before scoping the repair, remove all compromised material, replace with solid backing and finish wood, and leave the surface paint-ready or finish-matched to the surrounding trim. Moisture source identification is part of every assessment so the repair doesn't repeat.
What's Included
Full dry rot assessment, compromised wood removal, backing and structural replacement, and finish-ready surface restoration.
Common Dry Rot Repair Locations

Cost and Timeline
Cost Planning
Dry rot repair cost depends heavily on the extent of damage. Isolated window sill repairs run a few hundred dollars. Structural framing involvement or multi-location repairs can run mid-to-high four figures. We provide a written estimate after assessing the full scope.
Typical Timeline
Cosmetic repairs to window sills and door frames often complete in 1–2 days. Structural framing repairs or multi-location projects run 3–5 days. Paint and finish coordination may add additional time.

FAQ
Dry Rot Repair: Common Questions
Dry rot wood feels soft or spongy when probed, often discolors to brown or gray, and may crumble or pull apart in cube-like fragments. Common locations include window sills, exterior door frames, deck ledger boards, and areas near roof penetrations.
Yes. Dry rot fungi can spread through wood framing if moisture conditions persist. Early repair is important to prevent damage from expanding into structural members. We assess the full extent of affected wood during the site walk before scoping the repair.
Dry rot is typically excluded from standard policies as maintenance-related deterioration. If it resulted from a covered water event, a portion may apply. We recommend checking your specific policy before filing a claim.
Yes. Identifying and addressing the moisture source is part of every dry rot repair assessment. Repairing the wood without fixing the source leads to repeat damage within a few years.
