Exterior Work Built for March Point's Waterfront Exposure
March Point sits out on the water just south of downtown Anacortes, and that location comes with a specific set of challenges for anything mounted to the outside of a house. Homes here catch salt-laden air off the bay, take driving rain straight off open water during winter storms, and sit under enough shade and moisture through the fall and winter to grow moss on almost any surface that holds damp. It's a beautiful place to live, but it is not a forgiving place to own a house with the wrong siding, roofing, or trim.
We work throughout Skagit County, and March Point is one of the areas where we see the clearest difference between exterior materials that were built for this climate and materials that were not. Salt air accelerates corrosion on fasteners and hardware. Wind-driven rain finds its way into seams and laps that would stay dry in a more sheltered location. And a long, wet moss season means anything with texture or porosity is going to collect growth if it isn't the right product, installed the right way.

Why We Install James Hardie and Nothing Else
We are a James Hardie-only siding contractor. We don't install vinyl, LP SmartSide, Cemplank, Allura, primed spruce, or cedar, and that's a deliberate standard, not a lack of options. Fiber cement from James Hardie is non-combustible, dimensionally stable, and engineered specifically for the wet, marine-influenced climate of the Pacific Northwest. Hardie's HZ5 product line, in particular, is formulated for regions with more moisture exposure, which describes March Point about as well as anywhere in the county.
Wood-based siding products, including engineered wood, depend heavily on an intact factory coating and careful field sealing at every cut edge and joint. In a spot exposed to constant salt spray and driving rain, any gap in that protection becomes an entry point for moisture, and moisture is what leads to swelling, delamination, and rot over time. Vinyl siding can hold up structurally in this climate, but it doesn't resist moss and mildew growth the way a factory-finished fiber cement product does, and it doesn't offer the same fire performance or long-term color retention.
James Hardie's ColorPlus factory finish is baked on and warranted separately from the substrate, which means the color holds up under UV and salt exposure without the chalking or fading that repainted wood surfaces tend to show. Combined with Hardie's transferable warranty, it's a system built to be maintained with an occasional wash rather than a repaint cycle.
What Moss Season Does to an Exterior
Anacortes and the surrounding islands get a real moss season, usually running from late fall through spring, when shaded and north-facing walls stay damp for weeks at a time. On porous or textured siding, that moisture sits in the surface and gives moss and algae something to grip. Over years, that growth traps even more moisture against the wall.
Fiber cement doesn't eliminate moss and algae entirely, but its smooth, factory-sealed surface sheds water better than raw or lightly coated wood products, and it doesn't absorb moisture the way untreated wood substrates can. Correct installation matters just as much as the material choice here. Proper flashing, rainscreen gaps where called for, and correct caulking at penetrations all keep bulk water moving off the wall instead of sitting against it, which is exactly what a March Point exterior needs.
Roofing, Windows, and Decks Facing the Same Conditions
Siding isn't the only exterior system dealing with this environment. We also handle roofing, windows, and decks, and the same salt air, wind, and moisture that affect siding show up in those systems too.
- Roofing on waterfront and near-waterfront homes needs attention to flashing details and fastener corrosion resistance, since salt exposure speeds up wear on standard hardware.
- Windows need tight, correctly flashed installation so wind-driven rain doesn't push past the frame during winter storms coming off the water.
- Decks exposed to constant moisture and shade need materials and fastening that won't trap water against structural framing, especially where moss and algae growth is common.
Looking at the whole exterior together, rather than one component at a time, is how small moisture problems get caught before they turn into structural repairs.
Why a Local Crew Matters Here
A contractor working out of a different climate zone doesn't always account for what a marine environment like March Point does to a building over ten or twenty years. We're based in the Anacortes area, we work in Skagit County regularly, and we've seen firsthand how salt air, wind exposure, and moss season play out on real homes here, not in a general sense but on this specific stretch of coastline. That's part of why we standardized on a single, climate-appropriate siding system instead of offering whatever's cheapest for a given job.
Correct installation is just as important as material choice. Flashing details, fastener spacing, caulking, and clearance from grade all affect how well a siding system performs in wind-driven rain, and those details are easy to get wrong if a crew isn't used to building for this kind of exposure.
Get a Straightforward Look at Your Home's Exterior
If you own a home in March Point and you're noticing moss buildup, fading, soft spots, or drafts around windows, it's worth getting an honest assessment before those issues turn into bigger repairs. We offer free, no-pressure estimates for siding, roofing, window, and deck work, and we'll tell you plainly what we see and what we'd recommend, whether that's a full siding replacement or a smaller repair.
