Ferndale Exterior Work in Kendall, Washington
Kendall sits up in the northeast corner of Whatcom County, close enough to the foothills that homes here see a different mix of weather than properties down along the water in Ferndale or Bellingham. It's still Pacific Northwest marine climate, but the terrain and tree cover change how that weather actually lands on a house. We work throughout Whatcom County out of our Ferndale base, and Kendall is part of that regular service area — not a place we occasionally drive out to when someone happens to call.
A local crew matters more here than people sometimes expect. Homes in Kendall tend to sit closer to timber, get more shade for more of the day, and hold moisture longer after a storm passes than a house out in the open near the coast. That changes what siding, trim, and roofing decisions actually make sense.
What the Climate Does to Homes in This Area
Salt Air and Driving Rain
Whatcom County's proximity to the Salish Sea means salt-laden moisture works its way inland on wind-driven storms more than people realize, even well away from the immediate shoreline. Combine that with the driving, sideways rain that comes through on winter fronts, and exterior materials take a steady beating on their south and west-facing walls in particular. Fasteners, trim joints, and any seam in the exterior envelope are where that moisture finds its way in over time.
A Long Moss Season
Kendall's tree cover and elevation mean shaded roof and wall sections stay damp longer after rain than they would on a more exposed lot. That extended damp period is exactly what moss, algae, and mildew need to get established. On roofs, moss lifts shingles and holds water against the deck. On siding, sustained moisture behind or on the surface of the wrong material is a slow path to rot, delamination, or paint failure. A long moss season isn't a cosmetic issue — it's a material-durability issue, and it's one of the main reasons we're selective about what we put on houses in this part of the county.
Why We Only Install James Hardie Fiber Cement
We get asked fairly often why we don't offer vinyl, LP SmartSide, or one of the other fiber cement brands like Cemplank or Allura. The honest answer is that after years of doing exterior work in exactly this climate, we standardized on one product line because it holds up to what this region actually does to a house.
- Non-combustible: Fiber cement doesn't burn, which matters more every wildfire season in Washington, even this far west.
- Moisture-stable: James Hardie's fiber cement doesn't absorb and swell like wood-based composite products can when a seam gets compromised.
- Factory-cured ColorPlus finish: The finish is baked on in a controlled environment, not field-applied, which matters when you're dealing with our rain windows.
- Climate-engineered HZ product lines: Hardie makes region-specific formulations, and we use the HZ5 line suited to our Pacific Northwest exposure.
- Strong transferable warranty: A real, written warranty on both the product and the ColorPlus finish, which follows the house if it sells.
Vinyl siding is inexpensive and low-maintenance in the short term, but it can warp in temperature swings, fade unevenly on sun-exposed walls, and doesn't hold up structurally the way fiber cement does over a 30-plus year horizon. LP SmartSide and primed wood products are wood-based — engineered to resist moisture better than raw lumber, but still vulnerable at cut edges and seams if caulking and flashing aren't maintained, which is a real risk in a moss-prone, high-moisture area like Kendall. Cemplank and Allura are also fiber cement and reasonable products in general, but we've chosen to build our installation expertise, warranty relationships, and color-matching inventory around one manufacturer rather than spreading thin across several. That focus is what lets us install correctly, every time.
Siding Installation Done Right
Correct installation is what actually determines how a fiber cement job performs over decades, more than the product itself. We follow James Hardie's installation specifications closely because deviating from them is where most siding failures actually start — not from the material, but from shortcuts in the install.
What Correct Installation Includes
- Proper water-resistive barrier and flashing details at every window, door, and penetration
- Correct fastener type, spacing, and depth per Hardie's published specs
- Minimum clearance from grade, roofing, and decking surfaces to avoid wicking moisture
- Properly caulked and sealed joints, with attention to butt joints and corners
- Rain-screen or drainage plane detailing appropriate to the wall assembly
Skipping any of these doesn't show up as a problem on day one. It shows up three, five, or ten years later as staining, soft trim, or paint failure — usually in exactly the shaded, damp wall sections that a Kendall property tends to have more of than a house out in the open.
Roofing, Windows, and Decks — The Rest of the Envelope
Siding is only one piece of how a house sheds water. We handle roofing, window replacement, and decks as well, because a siding job done in isolation while the roof is shedding water onto the wall below, or old windows are leaking at the flashing, doesn't actually solve the underlying moisture problem.
Roofing
Moss removal, ventilation, and underlayment condition all matter more in shaded, tree-covered lots like a lot of what you find around Kendall. A roof that holds moss longer ages faster, and moss that migrates onto the top course of siding accelerates wear there too.
Windows
Old or poorly flashed windows are one of the most common points of water intrusion behind new siding. When we replace siding around existing windows, we check flashing and integration as part of the job rather than working around a compromised opening.
Decks
Decks attached to the house create a siding-to-deck ledger connection that has to be flashed correctly, or water works its way into the wall assembly right at that joint — a common failure point we see on older homes throughout the county.
Comparing Exterior Siding Options
| Material | Moisture Behavior | Maintenance | Typical Lifespan | Fire Rating |
|---|---|---|---|---|
| James Hardie Fiber Cement | Dimensionally stable, resists moisture-driven swelling | Low — factory finish, occasional wash | 30+ years | Non-combustible |
| Vinyl | Doesn't absorb water but can warp/gap at seams | Low, but color fades over time | 20-30 years | Combustible |
| LP SmartSide / Engineered Wood | Vulnerable at cut edges and seams if not maintained | Moderate — caulk/paint upkeep | 20-30 years with upkeep | Combustible |
| Cedar / Primed Spruce | Absorbs moisture readily, prone to rot in shaded areas | High — regular refinishing needed | 15-25 years with diligent care | Combustible |
What Drives Cost on a Kendall Project
Every property is different, but a few factors consistently move the price on siding, roofing, or window work in this area:
- Existing siding removal: Tear-off adds labor, especially with old wood or multiple layers.
- Home size and complexity: Dormers, multiple stories, and cut-up rooflines add trim and labor time.
- Moisture damage found underneath: Rot repair to sheathing or framing, if present, is priced separately once it's exposed.
- Trim and detail package: Corner boards, window trim, and fascia choices affect both material and labor cost.
- Access and site conditions: Sloped lots, tree-covered access, and staging room all factor into scheduling and labor.
We won't know exact numbers until we've actually looked at the house, but we're upfront about these factors during the estimate so there aren't surprises once work starts.
Why a Local Crew Makes a Difference
We're based in Ferndale, which means the crew showing up at a Kendall property already understands the microclimate differences within Whatcom County — the difference between a wide-open coastal lot and a shaded, tree-lined property further inland. That's not something a crew driving up from out of the area picks up on the first job. It shows in where we recommend extra flashing attention, how we talk through moss and moisture history with a homeowner, and how we schedule around the wetter stretches of the year.
Being local also means warranty service and follow-up calls aren't a logistical hassle. If a question comes up two years after installation, we're not far away.
