Dry Rot & Siding Repair in Camas, WA
Diagnosing and repairing dry rot and water intrusion, done right.
Camas is one of the Vancouver-metro communities in Clark County that we serve across Southwest Washington. When it comes to dry rot & siding repair, the details that matter here are specific to Camas homes.
Camas sits at roughly 82 feet, low on the valley floor, where a high water table and slow-draining ground keep crawlspaces, foundations, and the bottom courses of siding damp well after the rain stops. PRISM's 1991-2020 climate normals put it at about 49.2 inches of precipitation a year. For dry rot & siding repair, this climate is the whole problem: water gets behind cladding at flashing details and unsealed penetrations, then sits against sheathing and framing that never fully dries, which is why we chase the source and the drainage path rather than only replacing what looks rotten. Camas also sits at the western gate of the Columbia River Gorge, where east wind drives rain horizontally into walls that would stay dry elsewhere in the county — so dry rot & siding repair here is detailed for wind-driven water, and any James Hardie cladding follows the HZ5 guidance for this zone, all under the Washington State Energy Code.
This page covers dry rot & siding repair specifically for Camas. For the full service details, see our Dry Rot & Siding Repair page, or explore all the remodeling work we do in Camas.
Camas's housing stock tells the story of a former paper-mill town turned fast-growing suburb. Downtown Camas and the streets closest to the old mill hold smaller early-to-mid-1900s homes with real character and, often, original single-pane windows and dated wiring. Up the hill, Prune Hill and Dawson's Landing are dominated by 1990s-onward and newer custom and semi-custom construction with open layouts and larger lots. Because Camas sits at the mouth of the Columbia River Gorge, homes here see stronger, more consistent wind than communities further from the river, which we factor into siding fastening schedules, flashing details, and exterior trim as much as the region's rain and moisture.
From Downtown Camas, Prune Hill, and Dawson's Landing to the rest of Camas, 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 Camas 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 Camas?
It depends on the scope. City of Camas — Community Development sets the requirements for Camas, 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 Camas homes?
Yes. From Downtown Camas, Prune Hill, and Dawson's Landing to the rest of Camas, Camas in Clark 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.
How does Camas's weather affect dry rot & siding repair?
Camas averages about 49.2 inches of precipitation a year in PRISM's 1991-2020 climate normals. That is the constraint every detail on a dry rot & siding repair project has to answer to: assemblies need a drainage path and the ability to dry, and exterior stages get scheduled around the weather rather than against it. We plan the sequence so nothing is left open to the rain.
What should Camas homeowners know before starting dry rot & siding repair?
Two things specific to Camas. First, permits run through City of Camas — Community Development, whose requirements differ from neighboring Washington jurisdictions — we confirm what your address needs before work starts. Second, Camas sits at roughly 82 feet, and that low, slow-draining ground means crawlspace moisture and ground-contact detailing deserve a close look before anything is closed up. Both feed into the written scope and schedule you get before we start.
