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.

Common Dry Rot Repair Locations

  • Exterior door frame rot — bottom corners and threshold areas

  • Interior wall backing rot — behind shower enclosures and near plumbing
  • Structural post base rot — common in older homes with minimal post clearance from concrete

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.
