Ferndale Siding Exterior Work for Custer Homes
Custer sits in the rural stretch of northern Whatcom County between Ferndale and the Canadian border, close enough to Birch Bay and the Strait of Georgia that salt-laden air is a fact of life for anyone who owns a home out here. Add in the driving rain that comes off the water in fall and winter, plus a moss season that can stretch for most of the year under the tree cover many Custer properties have, and you've got a climate that is genuinely hard on exterior building materials. We've worked on homes throughout this part of the county long enough to know what that combination does to siding, trim, roofing, and anything else on the outside of a house.
What the Climate Does to a House Out Here
Custer's homes tend to sit on larger, more rural lots than in town, often with more tree cover and less direct sun exposure on at least one side of the house. That shade retains moisture longer after a rain, which is exactly the kind of environment moss, algae, and mildew need to take hold. Combine that with the salt air rolling in from the coast and you get a slow, steady breakdown of paint films, caulk joints, and any wood-based product that isn't sealed and maintained on a strict schedule.
- Moss and algae growth on north-facing walls and anywhere tree canopy blocks direct sun
- Paint and caulk failure happening faster than in drier parts of the state
- Moisture intrusion at trim, window, and door transitions where seals age and crack
- Wood rot in older siding, fascia, and deck framing that wasn't detailed for constant wet exposure
- Roof moss buildup that traps moisture against shingles and shortens roof life
Why We Standardized on James Hardie Fiber Cement
We install James Hardie fiber cement siding exclusively. We don't install vinyl, LP SmartSide, Cemplank, Allura, or primed wood species like spruce or cedar. That's a deliberate standard, not a sales pitch, and it comes directly from what we see on homes in climates like this one.
Fiber cement is non-combustible and dimensionally stable, so it doesn't expand, contract, warp, or delaminate the way wood-based and some engineered products can when they take on repeated moisture cycles. Hardie's ColorPlus finish is baked on at the factory rather than field-applied, which matters a great deal in a climate where paint failure is one of the most common callbacks we see on other products. Their HZ5 product line is engineered specifically for wetter, colder Pacific Northwest conditions, and the warranty coverage is transferable if the home sells. None of that is marketing shorthand — it's the reason we're comfortable putting our name behind the installation for years after we leave the job site.
We're honest that this isn't the cheapest option up front, and it's not the only siding product that can perform well when installed correctly. But given what we see fail on homes throughout Whatcom County, Hardie fiber cement is what we choose to stand behind, and it's the only siding system we install.
Siding, Roofing, Windows, and Decks
Most Custer properties we work on need more than one thing addressed at once, which is why we handle the full exterior rather than just siding.
| Service | What We Look At |
|---|---|
| Siding | Moisture-damaged sections, moss-prone wall faces, trim and flashing details around openings |
| Roofing | Moss accumulation, ventilation, flashing at valleys and penetrations |
| Windows | Seal failure, condensation between panes, flashing integration with siding |
| Decks | Ledger board attachment, framing rot, surface materials suited to constant wet exposure |
Looking at these together matters because a failure in one system often shows up as damage in another. A leaking window or poorly flashed roof valley can rot the siding and framing around it long before the problem is visible from the outside, and by the time it is visible, the repair is bigger than it needed to be.
Why a Local Crew Matters
Custer doesn't get the attention that Bellingham or even Ferndale proper does from larger regional contractors, but the climate challenges here are just as real, sometimes more so given the tree cover and proximity to the water. A crew that works this part of Whatcom County regularly knows which wall orientations grow moss fastest, which older homes were built with siding products that are now past their reasonable service life, and how to detail a new installation so it actually holds up to what this weather does year after year. That knowledge doesn't come from a manual — it comes from working on houses in this exact climate, season after season.
If you're noticing moss buildup, soft or discolored siding, paint that won't hold, or a roof that seems to stay wet longer than it should, we're happy to take a look. We offer free, no-pressure estimates for homeowners in Custer and the surrounding area — no obligation, just an honest assessment of what your home actually needs.
