Frequently Asked Questions
General Rot & Water Damage
You can, but you shouldn’t. Painting over rot is like putting a bandage on a deep infection. The paint traps the remaining moisture inside, actually accelerating the decay. The only permanent fix is to remove the affected wood entirely.
Our “shoulder seasons” (spring and fall) are long, damp, and cool—the perfect incubator for wood-decaying fungi. Unlike colder climates where rot goes dormant in freezing temps, our mild winters allow rot to eat away at your home nearly 365 days a year.
Despite the name, dry rot needs moisture to start. It refers to a specific type of fungi (Serpula lacrymans) that digests the parts of the wood that give it strength and stiffness. Once it starts, it can spread even through relatively dry timber, which is why it’s so dangerous for PNW homes.
Look for peeling paint, localized swelling, or a “spongy” feel when you press on the wood. If you see mushrooms or fungal growth sprouting from your siding, that’s a sign of a significant internal moisture problem.
In a way, yes. Fungal spores spread easily, and if the moisture conditions are right, rot will migrate from a piece of trim into your structural wall studs or rim joists. Catching it early is key to preventing a “house-wide” issue.
Costs, Insurance & Real Estate
It can, or it will at least lead to heavy price negotiations. We provide certified real estate reports and “fix-it” lists to help sellers address issues before they hit the market or help buyers understand the true cost of repairs.
It varies wildly based on the depth of the damage. A simple trim replacement might be a few hundred dollars, while structural beam replacement can range from $2,000 to $10,000+. We provide detailed estimates after an on-site inspection.
If the damage is limited to one wall or a few sections, repair is much more cost-effective. However, if more than 20-30% of your home has moisture issues, a full siding replacement with a modern moisture barrier is usually the better long-term investment.
Generally, no. Most insurance policies cover “sudden and accidental” damage (like a pipe bursting). Rot is considered “gradual damage” or a maintenance issue, which is why proactive inspections are so important for your wallet.
Decks & Exteriors
Fiber cement (like James Hardie) is the gold standard here because it’s rot-proof and fire-resistant. However, properly maintained Cedar is also excellent for our climate if you prefer a natural look.
Absolutely. This usually indicates either rotted support posts or a lack of proper lateral bracing. We can often reinforce the existing structure without needing a full rebuild.
Yes! Joist tape (butyl tape) is applied to the top of your deck framing. It seals around the deck screws, preventing water from seeping into the joist’s “end grain,” which can double the life of your deck frame.
The ledger board is where your deck bolts to your house. If this area rots, the deck can literally pull away from the structure, leading to collapse. It is the most critical safety point in any deck inspection.
Windows, Doors & Leaks
Door sills are high-traffic areas where water often sits. If the “pan flashing” under the door wasn’t installed correctly, every drop of water that hits the door eventually drains into the subfloor.
Not necessarily. If the window unit itself is still functional and sealed, we can often perform “trim-only” surgery, replacing the rotted wood with rot-resistant PVC or primed cedar.
Yes. That “occasional” leak is likely saturating the insulation and framing inside your wall every time it happens. Over time, this leads to hidden mold and structural decay that you won’t see until it’s a major project.
Safety, Mold & DIY
Small trim and siding repairs usually take 1–2 days. Larger structural projects or full deck rebuilds can take 1–2 weeks. We always provide a clear timeline before we strike the first hammer.
If it’s cosmetic trim, a handy homeowner can handle it. If it involves your foundation, wall studs, or floor joists, we strongly recommend professional repair to ensure your home remains structurally sound and stays within local building codes.
Mold grows on the surface and feeds on organic matter (like dust or paper backing on drywall), posing a health risk. Rot actually eats the fibers of the wood, posing a structural risk. You often find them traveling together.
In 99% of cases, yes. We use localized shoring to keep the structure safe. For mold-related repairs, we use containment barriers to ensure your indoor air quality remains high during the process.
Prevention & Maintenance
While we work year-round, the “best” time is whenever you find it. Waiting for a “dry spell” often allows another six months of rain to make the hole—and the bill—much larger.
We prioritize active water intrusion. If you have an active leak during a storm, we can often get a team out for “tarping and discovery” to stop the damage before it gets worse.
We primarily serve the I-5 corridor from Tacoma up through Seattle, Everett, Mt. Vernon, and Bellingham, including all surrounding communities near the Canadian border.
Absolutely. If gutters are clogged or overflowing, water runs down your fascia boards and behind your siding. This is one of the leading causes of “hidden” rot in Washington homes.
In the PNW, you should inspect your caulking every fall. High-exposure areas (south-facing walls) may need a refresh every 3–5 years to prevent water from sneaking behind your siding.
