Blaine Exterior Exterior Work Built for Lynden's Weather
Lynden sits inland from the water compared to some of our Whatcom County service area, but that doesn't mean the exterior of your home gets an easy ride. Homes here still deal with the same driving rain systems that roll off the Pacific and through the Nooksack Valley, long stretches of damp fall and winter weather, and a moss season that seems to start earlier every year. Add in the salt-tinged air that reaches inland on a west wind, and you've got a combination that wears down cheap materials faster than most homeowners expect.
Blaine Exterior Co works throughout this part of Whatcom County, and Lynden is a regular stop for us. We know what the local weather does to siding, roofing, windows, and decks over time, and we build our recommendations around what actually holds up here, not what looks good in a showroom.
What the Climate Does to a Lynden Home
Moisture is the common thread behind almost every exterior problem we see in this area. It's rarely one big storm that causes damage; it's the slow, repeated cycle of wet-then-dry, freeze-then-thaw, shade-then-sun that breaks down materials over years.
- Siding: Wood-based and engineered wood products can swell, delaminate, or take on moisture at seams and cut edges when they're rained on for months at a stretch. Once moisture gets behind the surface, paint failure and rot often follow.
- Roofing: Prolonged damp conditions and shaded rooflines are ideal for moss growth. Left unchecked, moss holds moisture against shingles and lifts them at the edges, shortening the life of an otherwise good roof.
- Windows: Aging seals and worn flashing let wind-driven rain find its way into wall cavities, which shows up later as staining, soft trim, or drafts.
- Decks: Uncovered or lightly shaded decks stay damp longer through the fall and winter, accelerating wear on fasteners, boards, and finishes.
Why We Install Only James Hardie Fiber Cement Siding
We get asked fairly often why we don't offer vinyl, LP SmartSide, or other engineered wood siding products. It's not that these products have no merit — vinyl is inexpensive and low-maintenance in mild conditions, and engineered wood siding can look good when it's new. But we've made a professional decision to install only James Hardie fiber cement siding, and it comes down to how these materials perform over the long haul in a climate like ours.
Engineered wood siding relies on resin-treated wood strands, and its long-term performance depends heavily on maintaining an intact factory coating and tight caulking at every seam and cut edge. In a region with as much sustained damp weather as Whatcom County gets, that's a maintenance burden we don't think homeowners should have to carry. Vinyl siding, for its part, can warp or become brittle with temperature swings and UV exposure over the decades, and it's a poor match for the wind-driven rain events that come through here.
James Hardie fiber cement doesn't share those weaknesses. It's non-combustible, it doesn't swell or rot from moisture the way wood-based products can, and it's engineered specifically for climates like ours through Hardie's HZ10 product line, which is formulated for wetter, harsher weather regions. The ColorPlus factory finish is baked on and warrantied against fading and peeling, so you're not relying on field-applied paint to hold up against years of rain and salt air. Combined with Hardie's strong transferable warranty, it's the product we're comfortable putting our name behind on Lynden homes.
Roofing, Windows, and Decks Done Right for This Area
Siding is only part of the picture. A roof in this area needs proper ventilation and moss-resistant materials, along with attention to valleys and flashing where water concentrates during heavy rain. Windows need flashing details that account for wind-driven rain, not just a bead of caulk. And decks benefit from materials and fastener choices that won't corrode or swell after a wet Whatcom County winter.
We approach all four of these systems as parts of one connected exterior. A new roof that isn't flashed correctly can undermine good siding work, and siding installed without attention to window and door transitions can let water in no matter how good the material is. Getting the details right at every seam and transition is what actually keeps a Lynden home dry over the long run.
Why a Local Crew Matters
Exterior contractors who don't work in this specific climate zone regularly can miss the details that matter here — the flashing details, the fastener choices, the siding clearances that keep moisture from getting trapped against the wall. We work this part of Whatcom County on an ongoing basis, so we're not guessing at what the weather does to a house over ten or twenty years. We're accounting for it in every job.
