Siding for a Peninsula That Takes a Beating
Point Roberts sits in a spot most siding never has to deal with. It's a small peninsula hanging off the bottom of Whatcom County, surrounded on three sides by the waters of Boundary Bay and the Strait of Georgia. That geography is part of what makes the community special, but it's also why homes here age differently than homes fifteen miles inland. Wind off the water carries salt onto siding, trim, and fasteners year-round. Rain comes in sideways more often than it falls straight down. And the same marine humidity that keeps lawns green through the summer keeps north-facing walls and shaded siding damp long enough for moss and algae to take hold and stay.
We're based in Blaine and have worked exteriors across this stretch of Whatcom County long enough to know that a siding job here isn't the same job you'd spec for a house in a drier, more sheltered area. Point Roberts homes need a product and an installation approach that account for constant moisture exposure, not just occasional rain.

What Salt Air and Coastal Moisture Actually Do to Siding
Salt-laden air is corrosive. It works on exposed metal fasteners, flashing, and hardware over time, and it accelerates the breakdown of coatings that aren't built to handle it. Combine that with near-constant humidity and a long moss season, and you get a set of problems that show up earlier here than they would elsewhere:
- Coating failure — paint and factory finishes that aren't engineered for marine exposure chalk, fade, and peel faster near open water.
- Trapped moisture — siding that can't manage water at the seams and laps stays wet longer in a climate where things rarely get a chance to fully dry out.
- Moss and algae growth — shaded, damp wall sections become long-term growth over a few seasons if the siding material and installation don't shed water cleanly.
- Fastener and flashing corrosion — hardware that isn't corrosion-resistant loosens or stains the siding around it well before the siding itself is due for replacement.
None of this means Point Roberts homes are doomed to constant maintenance. It means the material and the installation details matter more here than in a lot of places.
Why We Install Only James Hardie Fiber Cement
We standardized on James Hardie fiber cement siding for every home we side, and a coastal community like Point Roberts is exactly the environment that decision was made for. Fiber cement is non-combustible and dimensionally stable — it doesn't absorb moisture the way wood-based products can, and it holds its shape through the wet-dry cycling that's constant this close to the water. Hardie's ColorPlus factory-applied finish is baked on under controlled conditions and backed by its own finish warranty, which matters a great deal in a spot where field-applied paint takes a beating from salt air and UV reflecting off open water.
Hardie also builds climate-engineered product lines — HardiePlank, HardiePanel, and related systems are formulated differently for different regions, and the versions suited to the Pacific Northwest are built with this kind of marine, high-moisture exposure in mind. That's a level of engineering we don't get from vinyl, LP SmartSide, primed wood, or cedar, all of which come with trade-offs — moisture sensitivity, coating maintenance, or combustibility — that we'd rather not put on a home facing Point Roberts' weather. We're not saying those products have no place anywhere; we're saying that after years of exterior work in this climate, fiber cement is what we're willing to stand behind with a warranty.
How We Handle a Point Roberts Job
Because Point Roberts is geographically separate from the rest of Whatcom County — reachable primarily by driving through Canada or by water — logistics for any contractor take a bit more planning than a job across town. We build that into our scheduling up front: materials, crew, and equipment are staged so a Point Roberts project runs on the same timeline and to the same standard as any other job on our books. We're not stretching to cover it as an afterthought; it's part of our regular service area.
On the installation side, coastal work gets extra attention to the details that determine how long siding actually lasts:
- Corrosion-resistant fasteners and flashing appropriate for marine exposure
- Correct lap and joint sealing so wind-driven rain can't work its way behind the siding
- Proper clearance and drainage planes so walls can dry out between wet spells
- Attention to shaded and low-airflow wall sections where moss and algae are most likely to take hold
We also handle roofing, windows, and decks, which matters on a peninsula where the whole building envelope — not just the siding — is dealing with the same salt air and moisture exposure. A roof with failing flashing or windows with degraded seals can undermine even well-installed siding, so we look at the exterior as one system rather than a series of unrelated projects.
A Straightforward Look at Your Home
If you own a home in Point Roberts and you're noticing moss buildup, peeling paint, soft spots, or siding that just looks tired, it's worth having someone take an honest look before small problems turn into bigger repairs. We'll walk the exterior with you, explain what we're seeing in plain terms, and talk through what James Hardie siding would look like for your specific home — no pressure, no upsell.
