Can you just replace the rotten boards?

If the structure behind them is sound, yes — and we'll match your existing profile so the patch disappears. But if the sheathing is soft, swapping boards seals rot inside your wall. The probe tells us which situation you have, and we show you rather than tell you.

When is repair the wrong answer?

When rot shows on multiple elevations, when the siding is a failed product generation (like '80s–'90s LP-era boards), or when a west-facing wall is failing wholesale from strait exposure — repairing one board at a time on a wall the weather has beaten evenly is a treadmill. At that point full replacement costs less over ten years, and we'll show you the math either way.

Does homeowners insurance cover rot repair?

Usually not for gradual rot, which insurers treat as maintenance — but sudden water damage from a specific event sometimes qualifies. We document everything with photos either way, which gives you what you need if you pursue a claim.

How fast can you get to a rot repair on San Juan Island?

Repairs are smaller projects that slot into the schedule faster than full re-sides, and our Anacortes showroom is one sailing across the water — out-island roads are a planning item, not an obstacle. If a wall is actively taking on water, tell us — we can usually get it dried in quickly and schedule the full restoration from there.

WHY ROT HAPPENS HERE

How San Juan Island Walls Rot From the Inside

Weather off Haro Strait arrives with open-water momentum — rain driven sideways into west-facing walls through every failed seam and unsealed penetration, salt riding with it to corrode the fasteners that were supposed to hold the wall tight. Once water is behind the siding it can't dry out, and on out-island homes the damage often runs longer before anyone catches it: a farmhouse sill or a bluff-side wall can rot quietly for years between close looks.

That's why painting over a soft spot, caulking a gap, or swapping one board usually fails within a couple of winters — the water source and the rotten structure are still there. Real rot restoration means opening the wall to sound material, rebuilding the framing and sheathing, correcting the flashing detail that let water in, and only then re-siding the patch.

And when the damage is limited, a repair is genuinely the right call — we do them all the time, and we'll tell you when it's enough. When rot shows on multiple elevations of an older home, we'll show you the photos and the math on why a full re-side costs less than chasing failures wall by wall.

Where We Find It in San Juan Island

Bottom courses and sills on west- and south-facing walls, the original wood of homestead-era farmhouses in the valleys, window corners where flashing was skipped, and deck ledger connections on view homes — the strait finds the same weak points on every road out of town.

THE RESTORATION

How We Restore a Rotted Wall

Probe & Photograph

We find the true extent of the rot — it's always bigger than the visible spot — and document it before quoting.

Open to Sound Material

Siding and sheathing come off until we reach solid wood. No sealing rot inside the wall.

Rebuild & Re-Flash

Framing and sheathing restored, then the flashing or barrier failure that let water in gets corrected — the part quick fixes skip.

Re-Side & Blend

New siding matched to your existing profile and color so the repair doesn't show from the street.

Matching your existing siding profile is part of the job — lap reveals, shingle patterns, and trim details blended so the repair doesn't announce itself from the street.
