Burlington Serving Mount Vernon: Siding Done Right
Mount Vernon sits in the heart of Skagit County, close enough to the water and the valley floor that its homes deal with a specific mix of weather stress: salty, moisture-laden air drifting in off Puget Sound and the Skagit River delta, long stretches of driving rain through fall and winter, and a moss and algae season that can run most of the year on shaded, north-facing walls. We're based just up the road in Burlington, so this isn't a region we're guessing at — it's the same climate our own crews work in every week.
What Mount Vernon Homes Are Up Against
The Skagit Valley's marine-influenced climate is generous with moisture. Homes here see prolonged damp periods where siding, trim, and roofing rarely get a full chance to dry out between rain events. Add in salt-tinged air moving inland from the Sound, and you get a combination that's tough on paint film, tough on fasteners, and tough on any exterior material that isn't built to shed water and resist rot at the core.
- Moss and algae growth on shaded siding, roof valleys, and north-facing walls, especially near mature trees common in older Mount Vernon neighborhoods
- Paint and caulk failure from repeated wet-dry cycling, which shows up as cracking, peeling, or chalking years before it should
- Trim and corner-board rot where water sits against wood-based products instead of running off
- Window seal and flashing wear from wind-driven rain finding any gap in the building envelope
Why We Install James Hardie Fiber Cement — and Nothing Else
We made a decision as a company to install James Hardie fiber cement siding exclusively. We don't install vinyl, LP SmartSide, Cemplank, Allura, primed spruce, or cedar. That's not a marketing line — it's a standard we hold because of what we've seen these products do, and not do, in exactly this kind of climate.
Vinyl is affordable and low-maintenance in mild weather, but it can warp or become brittle over time, and its seams and expansion joints give wind-driven rain more opportunities to work its way behind the cladding. Wood-based composite siding and primed spruce depend heavily on an intact paint film to keep moisture out; once that film is compromised by our wet-dry cycling, the substrate underneath is vulnerable to swelling and rot. Cedar is a beautiful, genuinely traditional material, but it requires ongoing staining or sealing to hold up against sustained moisture exposure, and that upkeep is a real, recurring cost for the homeowner.
James Hardie fiber cement is engineered differently. It's non-combustible, dimensionally stable, and resistant to moisture-driven swelling and rot in a way wood-based and vinyl products simply aren't built for. Hardie's ColorPlus factory-applied finish is baked on under controlled conditions, which gives it far better resistance to fading and chipping than field-applied paint, and it comes backed by a strong, transferable warranty. Hardie also engineers specific HZ product lines for different climate zones, so we can spec the version actually suited to the Pacific Northwest's rain and humidity rather than a one-size-fits-all product.
How We Approach Exterior Work in Mount Vernon
Siding is only part of the equation. Water management on a home is a system — roofing, windows, siding, and trim all have to work together, which is why we handle all four:
- Siding: James Hardie fiber cement installed to manufacturer spec, with correct flashing and clearances so water is directed away from the wall assembly, not trapped against it
- Roofing: Proper underlayment, flashing, and ventilation detailing suited to a climate that sees sustained rain rather than short, hard storms
- Windows: Correct flashing and sealing at every window opening, since this is one of the most common places wind-driven rain finds its way into a wall
- Decks: Materials and detailing chosen to hold up to year-round moisture exposure and the moss growth that comes with it
Correct installation matters as much as the product choice. Fiber cement siding performs the way it's designed to only when the flashing, fastening, and joint details are done right — cut corners on installation and even the best material will underperform. That's the standard we hold every job to.
Why a Local Crew Makes a Difference
Working out of Burlington means we're a short drive from Mount Vernon, not a crew flying in from out of the area. We see how homes in this valley actually weather over the years — which walls take the brunt of the rain, where moss tends to establish first, and what details hold up versus what fails early. That local track record shapes how we spec and install every project, and it means someone is nearby if a question comes up after the job is done.
