Rotting Wood Spreading Fast? Professional Dry Rot Repair in Vancouver WA & Portland OR
In the Pacific Northwest, constant rain and humidity create perfect conditions for wood-destroying fungi. Left unchecked, a small patch of dry rot on your trim can spread to fascia, sheathing, and structural framing — turning a $500 repair into a $5,000 problem.
The Hidden Threat Inside Your Walls
More Than Just Soft Wood
That peeling paint or spongy trim board isn't just cosmetic. In the PNW's relentless moisture, wood-destroying fungi silently eat through your home's structure, compromising safety and sending repair costs climbing every month you wait.
Structural Compromise & Safety Risk
Dry rot doesn't stop at trim. The fungus follows moisture paths into wall framing, rim joists, and subfloors. In our experience, over 40% of fascia rot jobs in Salmon Creek and Hazel Dell reveal hidden framing damage behind the visible decay — damage that weakens your home's structural integrity.
Escalating Costs & Property Value Loss
Every month of delay lets rot spread further. A single rotted trim board that costs $400 to fix today can grow into $3,000-$5,000 in structural framing repairs within a year (source: National Association of Home Inspectors). Home inspectors flag dry rot as a major deficiency that kills deals and reduces offers.

Types of Wood Rot We Repair
Not all rot is the same. Our trained repair crews identify the type and extent of decay to apply the right treatment and replacement strategy for lasting results.
Dry Rot (Brown Rot)
Caused by Serpula lacrymans fungus. Produces brown, cubical cracking and can spread through masonry to reach new wood far from the moisture source. Risk: Rapid spread to structural framing even in relatively dry conditions.
Wet Rot
Occurs where wood stays consistently damp — around leaking gutters, failed caulk joints, and ground contact. Wood darkens, softens, and eventually crumbles. Risk: Subfloor and rim joist failure if moisture source isn't corrected.
White Rot (Soft Rot)
Breaks down lignin in wood, leaving a pale, fibrous, spongy texture. Common on decks, fence posts, and exterior stairs exposed to PNW rain and ground moisture. Risk: Sudden structural failure in load-bearing elements like deck posts and stair stringers.

Solid Wood, Like New Again
808+ Local Homeowners Protected
"Found soft, crumbling wood under our bathroom window and panicked. All Seasons came out next day, found it had spread into the framing behind the siding. They replaced everything — trim, sheathing, two studs — for $2,800. Took about a day and a half. Painted to match perfectly. You'd never know there was damage."

Our Methodology
Professional 5-Step Dry Rot Repair Process
Comprehensive Rot Inspection
We probe all trim, fascia, siding, and structural wood with moisture meters and awls to identify every area of decay — including hidden rot behind paint that looks fine from the ground.
Damage Mapping & Estimate
We document every affected area with photos, measure the extent of rot, and provide a transparent estimate broken down by repair zone so you know exactly what you're paying for.
Rot Removal & Treatment
All compromised wood is cut back to solid, healthy material. We apply borate-based fungicide to surrounding wood to eliminate remaining spores and prevent regrowth.
Structural Repair & Rebuild
New rot-resistant lumber (cedar, composite, or treated wood) is custom-fitted and installed to match your home's existing profiles. We reinforce framing where structural integrity was compromised.
Seal, Prime & Paint
Every repair is sealed with exterior-grade caulk, primed, and painted to match your home. We ensure moisture barriers are intact so the new wood stays protected for years.
Why All Seasons?
We don't just patch over rot with filler and paint. Our crews cut back to solid wood, treat with fungicide, and rebuild with rot-resistant materials — cedar, composite, or borate-treated lumber. That thoroughness is why our dry rot repairs last for years, not months.
