In Edgemoor, siding damage after a storm is almost never one dramatic event — it's wind-driven rain finding a gap that was already there, made worse over years of Whatcom County's near-constant drizzle. If a windstorm off Bellingham Bay just came through, the most useful thing you can do is walk the bluff-facing side of your house and look for lifted panels, dark staining, or soft spots before you call anyone, including us.
Whatcom County doesn't get hurricanes or hail the way other regions do, so it's easy to assume siding here just doesn't take storm damage. That's not quite right. What we see after a strong southwesterly blow off the Strait of Georgia and Bellingham Bay is water intrusion, not blown-off panels in most cases. Wind pushes rain sideways and upward under laps, around window trim, and behind loose J-channel. Because our storms arrive on top of ground that's often already saturated from weeks of steady rain, that water doesn't dry out between events — it sits.
Over time this shows up as a few predictable problems: soft or spongy fiber-cement or wood siding near the bottom courses, dark streaking below nail heads or seams, bubbling paint, and a musty smell in the wall cavity that homeowners usually notice inside before they see anything outside. On older cedar-clad Edgemoor homes, we also see actual wood rot at butt joints and around outside corners, where caulking has failed and nobody's looked closely in a decade. None of this is unique to Edgemoor, but the bluff location and unobstructed exposure to the bay make it happen faster there than in more sheltered parts of Bellingham.
A few things about Whatcom County weather change how siding fails compared to drier or hotter climates:
After wind and rain, don't start with a full siding replacement quote — start with a targeted inspection. Here's the order that actually makes sense:
One honest caveat: not every storm-damaged section needs the same fix. Fiber-cement repairs can often be done panel-by-panel and blended in with reasonable success. Wood siding repairs are harder to match invisibly, especially if the original cedar has weathered for years — replacement boards will look different until they weather in themselves, sometimes for a season or two. And moss removal alone, without addressing the shade and moisture source causing it, is a temporary fix; it tends to come back within a year or two on north-facing walls under trees, which is most of Edgemoor's canopy-covered lots.
Cost depends heavily on scope. Spot repairs to a section of storm-damaged lap siding are a different project than replacing rot-compromised sheathing behind it, and pricing swings accordingly — a small trim and panel repair might run a few hundred dollars, while sections with sheathing replacement or a full elevation redo run into the thousands. Get a written scope from whoever inspects it so you're comparing the same work across quotes.
Storm damage tends to be localized and tied to a specific event — lifted or cracked panels on the wind-exposed side, new staining that appeared right after a windstorm, or water intrusion you didn't have before. Normal weathering from Whatcom County's rain shows up more evenly across the house as faded finish, general moss growth, and gradual softening at the most exposed low points. If you can't tell the difference, that's a reasonable question to bring to an inspection rather than guess at — insurers care about the distinction even if it looks similar from the ground.
Most Washington homeowners policies cover sudden wind and wind-driven rain damage, but they typically exclude damage attributed to long-term neglect, gradual moisture intrusion, or lack of maintenance. Coverage details vary by carrier and policy, so the honest answer is: read your specific policy and, if you're unsure, ask your agent before you assume either way. A dated inspection report and photos taken close to the storm event give you the best chance of a claim being processed cleanly.
Shade and moisture retention. North-facing walls, and anything under mature evergreen cover — very common on Edgemoor's larger lots — dry out slower after rain than sun-exposed walls. Moss and algae spores take hold in that persistent dampness, and once established, the moss itself holds even more water against the siding surface, which is why it tends to come back unless the shading or moisture source is also addressed.
Yes — a full siding replacement in Washington is subject to the Washington State Energy Code as it applies to the exterior wall assembly, which affects the weather-resistive barrier, insulation approach, and window/door flashing integration at the time of the work. A licensed contractor should be able to explain how that applies to your specific project rather than just quoting a material swap.
If a recent windstorm off Bellingham Bay has you wondering whether your siding actually needs attention or just a cleaning, Alpine Exteriors will come look and tell you which one it is. We're a Washington-licensed contractor (ALPINI751OW) serving Edgemoor, Bellingham, Ferndale, Lynden, Blaine, Birch Bay, Sudden Valley, and the islands, and we've seen how differently this county's weather treats a bluff-facing wall versus a sheltered one. Reach out for an inspection before you decide between a repair and a full re-side — it's a lot easier to make that call with someone who's actually looked at the damage than from a guess off a photo.
