Dry rot is a type of wood decay caused by fungus that thrives in moist, poorly ventilated areas. It often starts behind siding, trim, or around windows where water seeps in and can spread quickly once established.

Common signs include soft or crumbling wood, peeling paint, musty smells, or discolored siding. You might also notice trim pulling away from the wall or paint that bubbles after rain. A professional inspection can confirm the extent of the damage.

Typical dry rot repairs for homes cost approximately $500 to $5,000 for most fixes — with the national average around $3500. For very minor, surface-level issues the cost may be under $500. If rot has spread into structural framing (floor joists, roof beams), costs can exceed $6,000 to $10,000+.

In many cases, yes. If the rot is limited to small sections, we can remove and replace only the affected areas. However, when damage is more extensive or hidden behind multiple layers, partial siding replacement is usually more effective.

Frequent rain, poor drainage, and lack of proper sealing are common culprits. The Pacific Northwest’s damp climate makes homes especially vulnerable if flashing, caulking, or paint maintenance is neglected.

Most small to medium repair projects are completed in 1–3 days. Larger or more complex repairs that involve framing or extensive siding replacement may take up to a week, depending on weather and access.

Yes, our team provides seamless repairs that include priming and painting once the woodwork is complete. We match your existing colors for a consistent, finished look.

Absolutely. We have extensive experience repairing rot on historic and pre-1978 homes using lead-safe certified practices. We take care to preserve your home’s original character while addressing underlying issues.

Keep your siding sealed and painted, maintain proper drainage, and inspect caulking and flashing annually. Catching minor leaks or peeling paint early is the best way to prevent moisture intrusion and future rot damage.

We take a targeted approach to find the source of the problem. Our team carefully removes exterior finishes in strategic areas to uncover the root cause of the rot and understand the full scope of the damage. This allows us to repair the affected wood correctly, prevent future moisture intrusion, and restore the structure without unnecessary demolition.

With dry rot, hidden damage is common. Reputable repair specialists will pause work, document what they find, and review the situation with the homeowner before continuing. This ensures clarity, avoids surprises, and keeps the homeowner in control of next steps.

Yes. Dry rot spreads rapidly, especially in moisture-heavy climates like Seattle and the Puget Sound region. Prolonged exposure to rain allows rot to move deeper into framing and structural components, turning small, localized repairs into expensive reconstruction work if left untreated.

Dry rot is a structural issue, and proper repair requires specialized training. Handymen or low-cost contractors may patch only the surface damage, leaving active rot behind. This often results in recurring problems and higher long-term costs. Choosing a specialist helps ensure the underlying decay is fully removed and rebuilt correctly.

Many contractors request a significant deposit before beginning repairs. Homeowners should be aware that large upfront payments can shift control to the contractor and reduce protection if scheduling delays or issues arise. Some companies offer pay-as-you-go structures for added transparency and peace of mind.

Look for proper licensing, bonding, and insurance, as well as a clear process for communication and documentation. Reliable contractors provide photos, updates, and references, helping homeowners understand what’s happening and ensuring repairs are completed correctly.

Absolutely. Seattle’s extended rainy seasons and year-round moisture create ideal conditions for rot growth. Even small leaks or siding gaps can introduce moisture that spreads quickly through wood framing. Early inspection and repair are especially important in this region.

Waiting can be risky. Moisture intrusion continues throughout the year in the Pacific Northwest, and postponing repairs allows damage to worsen. Professional crews can perform dry rot repairs in any season using weather protection and moisture-control methods.

Most dry rot repairs can be performed with minimal disruption. Experienced crews often work around occupant schedules, maintain clean job sites, and provide daily progress updates. For rental or multi-family properties, access and communication can be coordinated to avoid major interruptions.
