Dry Rot & Siding Repair in North Bonneville, WA
Diagnosing and repairing dry rot and water intrusion, done right.
North Bonneville is part of our wider Southwest Washington service area in Skamania County. When it comes to dry rot & siding repair, the details that matter here are specific to North Bonneville homes.
Near the western gateway to the Columbia River Gorge, North Bonneville sees both heavy Pacific Northwest rain and real east-county wind, so dry rot & siding repair here means planning for moisture, rot resistance, and wind-rated exterior detailing — with James Hardie's HZ5 guidance where siding is involved.
This page covers dry rot & siding repair specifically for North Bonneville. For the full service details, see our Dry Rot & Siding Repair page, or explore all the remodeling work we do in North Bonneville.
North Bonneville has an unusual history: the original townsite was relocated and rebuilt in the 1970s to make way for the second powerhouse at Bonneville Dam, so most of the city's housing dates to that planned rebuild rather than growing organically over decades. As with the rest of the Columbia River Gorge, wind is a real factor here alongside the region's heavy rainfall, which shapes how we spec siding fasteners, flashing, and trim.
From North Bonneville to the rest of North Bonneville, we match every dry rot & siding repair project to the age, construction, and condition of your specific home rather than a one-size-fits-all spec.

Moisture Investigation
We start by finding the actual water source — not just the visible damage. That means tracing flashing, siding laps, deck-ledger connections, and grade/drainage around the foundation before we scope any repair.
- 02
Open-Up & Assessment
We open the affected wall or trim area to see the full extent of the rot and confirm how far it's spread through the sheathing and framing, then document what we find with photos before pricing the repair.
- 03
Structural Repair
Damaged framing and sheathing are cut back to sound wood and replaced with new, properly protected lumber. We don't patch over rot — anything soft or compromised comes out.
- 04
Correct the Moisture Path
We install proper flashing, a rain-screen gap, and correct drainage detailing at the source of the original leak, so the rebuilt wall doesn't fail the same way again.
- 05
Re-Siding & Finish
New siding, trim, and paint or stain finish the repair to match the surrounding exterior, and we walk the completed work with you.
Typical timeline: Varies by scope and extent of damage. We provide a written schedule after assessing your North Bonneville home.

How do I know if I have dry rot?
Common signs are soft or spongy trim and siding, paint that's bubbling or peeling in one spot, a musty smell near an exterior wall, or discoloration around a window, deck ledger, or roofline. Dry rot often starts hidden behind siding, so by the time it's visible from outside it's usually been developing for a while. If you're seeing any of these signs, it's worth having it assessed before it spreads further.
What usually causes dry rot in Southwest Washington homes?
Almost always a failure somewhere in the moisture path — missing or corroded flashing, siding installed without a rain-screen gap so it traps water against the sheathing, a deck ledger that was never properly flashed where it meets the house, or a soffit vent that lets moisture build up in an eave. Our long, wet season means any one of those gaps has months to do damage every year.
Do you just patch the damaged area, or fix what caused it?
Both, and in that order — we can't do one without the other. Rebuilding a rotted wall without correcting the flashing or drainage that let water in just sets up the same failure again. Every repair includes finding and correcting the actual moisture source, not just replacing the wood you can see.
Is dry rot repair urgent, or can it wait?
It's worth addressing promptly. Dry rot spreads as long as the moisture source stays active, and what starts as a soft trim board can migrate into structural framing, sheathing, and eventually the wall's ability to carry load. Catching it early is almost always a smaller, less invasive repair than waiting.
Can this be done alongside a re-side or deck project?
Yes, and it often should be. A re-side is the natural time to correct flashing and add a rain-screen gap across the whole wall; a deck rebuild is the time to properly flash the ledger connection. We coordinate rot repair with those projects so you're not paying to open the same wall twice.
Do I need a permit for dry rot & siding repair in North Bonneville?
It depends on the scope. City of North Bonneville — Building Department sets the requirements for North Bonneville, and they can differ from neighboring Washington jurisdictions. We confirm what your project needs before we start and handle the permit and inspection process as part of the job.
Do you handle dry rot & siding repair on both older and newer North Bonneville homes?
Yes. From North Bonneville to the rest of North Bonneville, North Bonneville in Skamania County spans a range of housing eras and construction types, and we tailor the dry rot & siding repair plan to the age and condition of your specific home rather than a one-size-fits-all template.
