Ferndale Siding Siding Installation Built for Custer's Weather, Not Just Its Looks
Custer sits in a rural pocket of Whatcom County, close enough to Puget Sound and the Strait of Georgia to catch salt-laden wind off the water, open enough to farmland and tree lines to take driving rain sideways during winter storms, and shaded enough on many lots that moss and algae get a long season to work on anything that stays damp. Siding here isn't a cosmetic decision. It's the one layer standing between your framing and a climate that rarely gives a wall time to fully dry out between storms.
We install siding for homes in and around Custer with that reality in mind — not a generic install, but one sized to what this specific stretch of Whatcom County throws at a house year-round.
What Custer's Climate Actually Does to Siding
Salt Air
Even a few miles inland, salt-bearing wind off Puget Sound and the Strait accelerates corrosion on fasteners, flashing, and any metal trim that isn't rated for coastal exposure. Cheap or mismatched fasteners are one of the most common reasons siding fails early in this part of the county — not because the siding panel itself failed, but because what's holding it up rusted first.
Driving Rain
Open farmland and exposed lots around Custer mean wind-driven rain hits walls at an angle, not straight down. That puts real stress on laps, seams, and butt joints — any place water can be pushed sideways or upward instead of just running off. An installation that would be fine in a sheltered subdivision can leak here if the laps and flashing details aren't done to spec.
Moss and Algae Season
Shaded, tree-lined lots and the region's long wet season give moss and algae months to establish themselves on north-facing walls and anywhere airflow is blocked. Siding that stays damp for weeks at a stretch needs a finish and an installation gap that actually lets it dry, not just a coat of paint that looks clean on day one.
What a Correct Installation Involves
A siding job that holds up in Custer isn't just nailing panels to the wall. The parts nobody sees are what determine whether the job lasts fifteen years or fifty.
- A continuous weather-resistive barrier installed with proper laps and no gaps, tears, or shortcuts around penetrations
- Correctly flashed windows, doors, and any wall penetration, with flashing that directs water out and away rather than behind the cladding
- Rain screen or drainage gap where the wall assembly calls for it, so moisture that does get behind the siding has somewhere to go
- Fasteners rated for coastal and high-moisture exposure, driven to the manufacturer's depth and spacing — not just "close enough"
- Proper clearance between the bottom of the siding and grade, decks, patios, and roof lines, so splashback and standing water don't sit against the board
- Caulking and sealant only where the manufacturer specifies it — over-caulking traps moisture just as often as under-caulking lets it in
Skip any one of these and the siding itself becomes irrelevant. We've seen premium boards fail early because of a missed flashing detail, and we've seen modest siding hold up for decades because the install underneath it was done right.
Why We Install Only James Hardie Fiber Cement
We don't offer a menu of siding brands for Custer homes. We install James Hardie fiber cement, full stop, and we tell every homeowner why before they sign anything.
Fiber cement doesn't feed moss the way wood-based products can, and it doesn't swell, delaminate, or rot the way engineered wood siding can when a seam takes on water. It's non-combustible, which matters given how many Custer properties border open fields, brush, and treed lots where wildfire risk is a real consideration, not a hypothetical one. Hardie's ColorPlus factory finish is baked on under controlled conditions rather than field-applied, which means better, more even coverage than a site-painted product and less maintenance repainting over the life of the siding.
Hardie also engineers specific product lines by climate zone. For the Pacific Northwest's wet, marine-influenced conditions, that means a formulation designed to handle sustained moisture exposure rather than a one-size-fits-all board. That's a meaningful difference in a place where siding spends a good part of the year wet.
Why We Turn Down the Alternatives
We get asked about vinyl, LP SmartSide, cedar, and primed spruce fairly often, and we're straightforward about why we don't install them:
| Product | What it does well | Why it's a harder fit for Custer |
|---|---|---|
| Vinyl siding | Low upfront cost, low maintenance in mild climates | Can warp or crack in wind-driven storms; seams and laps are more vulnerable to the salt air and driving rain common here |
| LP SmartSide | Engineered wood strength, workable installation | Wood-strand core is more sensitive to sustained moisture exposure than fiber cement if any seam or cut edge is compromised |
| Cedar siding | Natural look, long regional tradition | Needs regular refinishing to resist moss and moisture in a climate that gives it little time to dry between rain events |
| Primed spruce | Lower material cost | Primer is a starting point, not a finish — ongoing paint maintenance is required to keep moisture out long-term |
None of these are bad products in every setting. They're just products we've decided aren't the right long-term fit for the moisture and salt exposure a Custer home deals with, and we'd rather turn down a job than install something we don't think will hold up here.
Our Process for a Custer Siding Installation
- On-site assessment. We walk the exterior, check current siding condition, sheathing, and any existing moisture or rot damage, and note exposure — which walls take the worst of the wind-driven rain and salt air.
- Plan the water management details. Before a single Hardie board goes up, we plan the weather barrier, flashing, and drainage gap specific to your home's layout and exposure.
- Tear-off and sheathing repair. Any damaged sheathing found during tear-off gets repaired before new siding goes on — covering rot doesn't fix it.
- Install to Hardie's fastening and clearance specs. This is where warranty coverage lives or dies. We install to the manufacturer's published requirements, not shortcuts.
- Trim, flashing, and final detailing. Corners, window and door trim, and penetration flashing get finished to shed water, not just look finished.
- Final walkthrough. We review the completed job with you before calling it done.
Signs a Custer Home Needs New Siding
- Persistent moss or algae staining that comes back within weeks of cleaning
- Soft spots, bubbling, or visible warping, especially on north-facing or shaded walls
- Paint that's peeling or blistering rather than just fading evenly
- Visible gaps at seams, corners, or trim where daylight or drafts get through
- Rising heating bills with no other clear cause, which can point to a compromised weather barrier
- Rust streaking from fasteners or trim, a common early warning in salt-air exposure
Any one of these on its own isn't necessarily an emergency. Several together, especially on a home that's had the same siding for fifteen-plus years, is usually a sign it's time for an honest look.
What Affects the Cost of a Siding Installation
| Factor | Why it matters |
|---|---|
| Home size and wall complexity | More corners, gables, and dormers mean more cutting, flashing, and labor time |
| Current siding condition | Tear-off and sheathing repair add time and cost if there's existing damage underneath |
| Siding profile and finish | Lap width, texture, and color options within the Hardie lineup affect material cost |
| Access and site conditions | Tree cover, slope, and setback affect staging, scaffolding, and crew logistics |
| Trim and detail work | Custom trim, extra flashing at penetrations, and detailed corner work add labor |
We won't quote a number without seeing the home, but these are the factors that actually move the price, not the sales pitch factors that don't.
Why It Matters That We Already Work in Custer
A crew that's installed siding on other Custer and Whatcom County homes already knows the local exposure patterns — which sides of a house typically take the worst rain, how moss establishes on shaded lots in this area, and what fastening and flashing choices actually hold up against salt air over time. That's not something you get from a crew doing its first job in the area. It's also worth knowing that a company committed to a single, correctly-specified product system tends to install it more consistently than a crew juggling four different manufacturers' installation requirements from job to job.
