Cherry Point's Siding Problem Isn't Like Everywhere Else
Cherry Point sits right up against Georgia Strait, which means homes here take a different kind of beating than a house ten miles inland in Blaine proper. You've got salt-laden air coming off the water, wind-driven rain that hits siding sideways instead of straight down, and a moss season that can run eight or nine months out of the year given how much shade and moisture Whatcom County gets. Any siding product installed here has to handle all three at once, not just one of them.
We've worked enough homes in this area to know the failure patterns before we even walk the property: paint that chalks and fades faster on the water-facing walls, moisture trapped behind poorly flashed siding that never gets a chance to dry out, and moss and algae staining that shows up first on north- and west-facing elevations. A siding job that doesn't account for those three things from the start is a siding job you'll be dealing with again in five to eight years instead of thirty.

Why Fiber Cement Fits This Location
Fiber cement isn't a fashion choice out here — it's a practical one. It's made from cement, sand, and cellulose fibers, so it doesn't absorb water and swell the way wood-based products can, and it doesn't corrode or pit the way some metal siding does when it's constantly exposed to salt air. For a property this close to the water, that resistance to moisture absorption is the single biggest factor in how long the siding actually lasts.
What Salt Air Does to the Wrong Siding
Salt air accelerates the breakdown of a lot of building materials. It pulls moisture into anything porous, it speeds up corrosion on fasteners and trim, and it degrades cheaper paint finishes faster than inland exposure would. Vinyl siding can become brittle and discolored faster in this environment, and wood-based composite products are more vulnerable to the swelling and edge deterioration that come from repeated wetting near the coast. Fiber cement, done correctly, resists all of that far better.
What Driving Rain Does to a Bad Installation
Wind off the strait doesn't let rain run straight down a wall — it drives it sideways and forces it into every gap, seam, and fastener hole it can find. This is where installation quality matters more than the product itself. Even the best siding material will fail early if the flashing, house wrap, and seam gaps weren't done to handle wind-driven moisture. We've seen call-backs on other contractors' work where the siding itself was fine but the water management behind it wasn't, and the sheathing underneath paid the price.
What a Correct Fiber Cement Job Looks Like in Cherry Point
There's a difference between siding that's nailed up and siding that's installed to spec, and in a coastal-exposure area like this the gap between those two shows up fast. A correct job includes:
- Proper weather-resistive barrier installed and lapped correctly before any siding goes up
- Rainscreen or drainage gap where conditions call for it, so any moisture that gets behind the siding has somewhere to go
- Correct fastener type and placement — coastal exposure means fastener corrosion resistance matters more than it does inland
- Flashing at every window, door, and roof-to-wall intersection, not just the obvious spots
- Proper clearance from grade, decks, and roof lines so the bottom edge of the siding isn't sitting in standing moisture
- Factory-finished panels installed with manufacturer-specified gaps and sealant, not caulked tight everywhere out of habit
Skip any one of these and you're not really getting the benefit fiber cement is supposed to give you — you're just getting a more expensive version of the same moisture problems.
Moss, Algae, and the Cherry Point Shade-and-Moisture Combination
Long moss seasons aren't just a roofing problem. Siding that stays damp for extended stretches — because it's shaded by trees, facing away from the sun, or sitting close to landscaping that holds moisture against the wall — will grow moss and algae over time regardless of the material. What changes is how the surface holds up to it and how easy it is to clean.
James Hardie's ColorPlus factory finish is baked on and cured in a controlled environment, which gives it better resistance to the surface staining and streaking that come from prolonged moisture and organic growth compared to field-applied paint. It won't stop moss from ever landing on a shaded wall, but it holds its color and cleans up better over the years than a lot of alternatives, and it doesn't need repainting on the same cycle a wood-based product would.
Why We Only Install James Hardie
We don't install LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar, and that's a deliberate call, not an oversight. Each of those products has real strengths, but in a coastal Whatcom County environment the trade-offs stack up against them: wood-based composites are more sensitive to sustained moisture exposure, vinyl can become brittle and show UV and salt-air wear faster, and field-finished or unfinished wood siding demands a maintenance schedule most homeowners don't want to keep up with for thirty years.
James Hardie's fiber cement is engineered specifically for demanding climates, backed by a factory finish warranty on ColorPlus products, and has a long track record in exactly this kind of coastal, high-moisture environment. We install exclusively with Hardie because we're not interested in putting something on a Cherry Point home that we'll be back to explain in eight years — we'd rather install it once, correctly, with a product built for this exposure.
Cost Factors Specific to This Job
| Factor | Why It Matters Here |
|---|---|
| House wrap / drainage plane condition | Coastal wind-driven rain demands a functioning water management layer behind the siding — replacing a failed one adds labor but is not optional |
| Fastener and flashing spec | Corrosion-resistant fasteners and full flashing at every penetration cost more up front but prevent early failure near salt air |
| Trim and color selection | ColorPlus factory finish carries a different cost than field-painted trim, but performs better long-term in this environment |
| Existing siding removal and sheathing condition | Homes with prior moisture intrusion may need sheathing repair before new siding goes on — this isn't discovered until tear-off |
| Access and elevation exposure | Water-facing walls may need extra prep time and attention to detailing versus more sheltered elevations |
We'll never give you a number over the phone that ignores what's actually on the wall. A walk-through tells us what condition the sheathing and existing water barrier are in, which is usually the biggest cost variable on a coastal re-side.
Our Process for a Cherry Point Home
1. On-Site Assessment
We look at sun exposure, wind direction relative to the structure, existing moisture damage, and how the current siding has held up — that tells us more than a satellite photo ever could.
2. Tear-Off and Sheathing Check
Once the old siding is off, we check the sheathing and existing barrier for hidden moisture damage before anything new goes up. This is the step that gets skipped on rushed jobs and it's the one that matters most in this climate.
3. Water Management Installation
Correct house wrap, flashing, and drainage detailing come before a single piece of Hardie panel gets hung.
4. Fiber Cement Installation to Manufacturer Spec
Proper gaps, fastener schedule, and sealant per James Hardie's installation instructions — not shortcuts based on what's faster.
5. Final Walkthrough
We go over trim, seams, and flashing details with you directly before calling the job done.
Why Local Experience with This Exposure Matters
A contractor who mostly works inland jobs in Whatcom County isn't necessarily thinking about wind direction off the strait, salt exposure on fasteners, or how a north-facing wall near Cherry Point will hold moisture differently than a south-facing one three miles away. Those details don't show up in a generic estimate — they show up five years later as callbacks. Working this specific stretch of coastline repeatedly means we already know where the moisture problems tend to start on these homes, and we build the installation around avoiding them instead of reacting to them later.
A Quick Homeowner Checklist Before You Re-Side
- Ask what water-resistive barrier and drainage approach the contractor plans to use, not just what siding brand
- Ask about fastener type and corrosion resistance for a coastal property
- Ask how flashing will be handled at windows, doors, and roof lines specifically
- Ask whether sheathing will be inspected during tear-off, and what happens if damage is found
- Ask what warranty covers the factory finish versus the installation labor
