Anacortes Exterior Why March Point's Exposure Changes What Siding Should Do
March Point sits out on a low, open peninsula along Fidalgo Bay, and that location matters more than most homeowners realize when it comes time to re-side a house. Homes here catch wind and salt-laden air moving straight off the water, with little in the way of tree cover or terrain to break it up the way you'd get further inland in Anacortes proper. That combination of salt air, driving rain off Puget Sound weather systems, and a long damp season is a tougher environment for exterior materials than a typical Skagit County suburb.
Salt air is corrosive to metal fasteners and trim, and it accelerates the breakdown of anything that relies on a painted or coated surface film to stay protected. Driving rain — wind-blown rain that hits siding at an angle instead of falling straight down — pushes moisture into laps, seams, and fastener penetrations that would stay dry on a calmer site. And the long gray stretch from fall through spring that Western Washington is known for gives moss and algae months of damp, shaded surface to colonize before summer sun ever dries things out. None of this means March Point is an impossible place to side a house. It means the material and the installation details matter more here than they would somewhere drier and more sheltered.
What March Point Homes Actually Need From Their Siding
Given that exposure, we look at four things whenever we evaluate a home out here:
- Moisture management behind the cladding — not just a siding surface that sheds water, but a wall assembly built to drain and dry when moisture inevitably gets past the outer layer.
- Dimensional stability — a product that won't swell, cup, or delaminate after repeated wet-dry cycles through the winter and spring.
- A factory finish that holds up to salt air — field-applied paint fails faster in this environment than a baked-on factory finish, especially on south and west exposures that also take direct sun.
- Resistance to moss and algae growth — surfaces and details that don't trap standing moisture in shaded, north-facing wall sections where growth takes hold first.
Those four requirements are exactly why our recommendation for this area doesn't waver from house to house — the climate is consistent even when the homes aren't.
Why We Only Install James Hardie Fiber Cement
We install James Hardie fiber cement siding exclusively. We don't install vinyl, LP SmartSide, cedar, primed spruce, or other fiber cement brands like Allura or Cemplank. That's a deliberate professional standard, not a sales preference, and it comes down to what actually holds up in a place like March Point.
Fiber cement is non-combustible, dimensionally stable, and doesn't rely on a thin surface coating the way vinyl and untreated wood products do. Hardie's ColorPlus factory finish is baked on under controlled conditions rather than field-applied, which gives it better adhesion and fade resistance than site-painted siding — a real advantage when salt air is working against the finish year-round. Hardie also engineers specific product lines for different climate zones; the HZ5 line used throughout the Pacific Northwest is formulated for our wetter, milder climate rather than the hot, dry conditions other regions deal with. On top of the material itself, Hardie backs its products with a strong transferable warranty when the installation is done to their specification — which is the other half of this equation, and where a lot of siding jobs actually fall short.
We're not going to claim other products are junk — vinyl is inexpensive and easy to find installers for, and cedar has real appeal if you like the look and are willing to keep up with it. But for a house exposed to salt air and driving rain on a peninsula like this, we've made the call that fiber cement done right is the product worth standing behind, and we only put our name on work we're confident will hold up.
Where Other Products Fall Short Out Here
Vinyl siding can warp or bow under sustained direct sun and temperature swings, and its seams and J-channels give wind-driven rain more opportunities to work moisture behind the panel over time. LP SmartSide and other wood-strand products are engineered wood — better than raw cedar in some respects, but still wood-based, meaning any breach in the surface treatment lets moisture in at the core, which is a real risk in a climate that stays damp for months at a stretch. Cedar and primed spruce are natural wood products that need ongoing painting or staining to stay protected; skip a maintenance cycle in a salt-air environment and you'll see it in the finish within a year or two.
What a Correct Siding Installation Actually Involves
The siding itself is only part of the system. Most siding failures we see out here — regardless of brand — trace back to installation shortcuts, not the material.
Weather-Resistive Barrier and Flashing
Every wall gets a continuous weather-resistive barrier behind the siding, with flashing detailed at every window, door, and penetration so water is directed out and down rather than trapped behind the cladding. On a site exposed to driving rain, sloppy flashing work is where leaks start — often years later, long after the crew that did the work is gone.
Fastening and Clearances
Hardie siding has specific fastening patterns and requires corrosion-resistant fasteners — a detail that matters even more in salt air, where the wrong fastener can rust and streak the siding face within a few seasons. We also hold proper clearance between the bottom of the siding and grade, roof lines, decks, and hardscape, so water and debris don't wick moisture into the bottom edge of the boards.
Caulking, Trim, and Gaps
Butt joints, trim edges, and penetrations get sealed per manufacturer spec, using sealants rated for exterior exposure — not just whatever caulk was on the truck. Gaps left uncaulked, or caulked with the wrong product, are one of the most common places we find hidden moisture damage when we tear off older siding.
Our Process for a March Point Siding Project
Assessment and Measurement
We start by walking the whole exterior, checking existing siding, trim, and sheathing condition, and paying particular attention to wall sections facing the water and prevailing wind. We look for existing moisture damage before we ever talk about new siding, because covering up a wet wall assembly with new material doesn't fix anything.
Tear-Off and Prep
Old siding comes off, sheathing is inspected and repaired as needed, and the weather-resistive barrier and flashing are installed correctly before a single piece of new siding goes up. This is the stage that determines how the house performs for the next several decades — it's not visible once the job is done, but it's the part we won't rush.
Installation
Hardie panels, planks, or trim go up per manufacturer specification — correct fasteners, correct spacing, correct clearances, proper caulking at joints and penetrations.
Final Walkthrough
We walk the finished job with the homeowner, check every elevation, and confirm trim, caulking, and touch-up paint are complete before we consider the job done.
Cost Factors for a March Point Siding Project
Every home is different, but these are the main variables that move the price of a siding job in this area:
| Factor | Why It Matters |
|---|---|
| House size and wall complexity | More elevations, dormers, and trim details mean more cutting, flashing, and labor time |
| Existing wall condition | Rotted sheathing or hidden moisture damage found during tear-off adds repair scope |
| Product selection | Lap siding, panel siding, and shingle-style Hardie products carry different material and labor costs |
| Trim and accessory work | Fascia, soffits, and trim boards replaced alongside siding add scope but improve the final result |
| Site access and exposure | Waterfront or wind-exposed sites may need additional flashing and sealant detail |
We give every homeowner a written estimate that breaks these factors down, so you know what you're paying for and why — not a single lump number with no explanation behind it.
Signs Your Current Siding Is Already Failing
If you're not sure whether your March Point home needs new siding yet, look for these signs before committing either way:
- Soft or spongy spots when you press on the siding, especially near the bottom edge
- Persistent moss, algae, or dark streaking that returns soon after cleaning
- Paint that's peeling, bubbling, or chalking heavily on wood or previously painted surfaces
- Visible warping, cupping, or gaps opening up at panel seams
- Rust streaks running down from fasteners or trim
- Rising interior humidity, musty smells, or peeling interior paint near exterior walls
Any one of these on its own might just need attention rather than full replacement — but a few together, especially on the wind-facing side of the house, usually means the wall assembly is due for a real look.
What to Look For When Hiring a Siding Contractor in This Area
A crew that already works March Point and the rest of Anacortes regularly will know how differently a house on this peninsula ages compared to one a few miles inland — that's not something a contractor coming from outside Skagit County necessarily accounts for. When you're vetting a siding contractor here, ask directly:
- Do they install to the manufacturer's written specification, and can they explain what that includes?
- Do they carry current licensing and insurance, and will they provide proof without being asked twice?
- Will they show you the flashing and weather-barrier detailing before it's covered by siding, not just the finished exterior?
- Do they offer a manufacturer-backed warranty, and do they explain what voids it?
- Can they speak specifically to how salt air and moisture affect materials in this area, rather than giving a generic answer?
