Dry Rot Repair

Dry Rot Repair & Exterior Restoration

Dry rot is a moisture problem first and a carpentry problem second. We trace the source, replace what's compromised, and re-detail the wall so it doesn't come back.

Dry Rot Repair & Exterior Restoration

Why homeowners choose this with Sierra Siding

  • Find and stop the moisture source — not just replace the visible rot
  • Replace compromised framing, sheathing, fascia, and trim
  • Rebuild flashing and weather-resistive barrier where the failure started
  • Restore siding finish so the repaired area reads as one wall

Rot is a symptom, not the disease

Dry rot needs three things: wood, moisture, and time. Replacing the wood without removing the moisture path means we'll be back in two years. The first job on every dry rot project is identifying where the water is getting in — failed flashing, a reverse-lapped barrier, a deck-to-wall detail, ground contact, a leaky gutter, blocked weep paths — and closing it.

Where we find it most

Around windows and doors where flashing was reverse-lapped or skipped, at deck-to-wall connections, at the base of walls below failed gutters, behind unflashed hose bibs or light fixtures, and at fascia where ice or pooled water has worked behind the drip edge. Tahoe and the foothills add freeze-thaw to the mix; the Bay adds prolonged marine moisture.

Scope is honest, not scary

We probe the extent before we quote. Sometimes rot is contained to a single stud bay and a square of sheathing; sometimes it ran along a sill plate for ten feet. Either way the homeowner sees the same documentation we see, and the written scope reflects the actual conditions — not a worst-case estimate to pad the job.

FAQ

Common Questions

Soft spots in trim or siding that give under a probe, paint that won't stick or bubbles repeatedly, dark staining around windows or at the base of walls, or visibly punky wood at fascia and rafter tails. We can probe non-destructively during a free assessment.

Sometimes, when the rot is limited to fascia, trim, or an isolated section of sheathing accessible from outside. Larger rot zones typically require pulling siding back to expose and properly rebuild the assembly — and that's the right move when the alternative is recurring failure.

Usually not — most policies treat long-term moisture damage as maintenance, not a covered loss. Sudden water events (a pipe burst, storm impact) may be covered. We document conditions clearly so you can have an informed conversation with your carrier.
