Old Town Anacortes Has Its Own Siding Problem
Old Town Anacortes is one of the older residential pockets of the city, and homes here carry a different set of siding problems than a new build out on the edge of town. Older wall assemblies, decades of prior repaints, and a location close to the water all combine to put more stress on exterior siding than most homeowners realize until a wall starts showing it. When we get called out to a home in this neighborhood, we're rarely dealing with a blank slate — we're dealing with a house that has already been through a few rounds of paint, patch, and partial repair, sitting in one of the more exposed microclimates in Skagit County.
This page is specifically about fiber cement siding for Old Town Anacortes homes: what the local climate does to walls here, what a correct installation actually requires, and why we install James Hardie fiber cement exclusively rather than the cheaper or trendier alternatives on the market.

What Salt Air, Driving Rain, and Moss Actually Do to a Wall
Salt-laden air
Anacortes sits surrounded by saltwater — Guemes Channel, Rosario Strait, and Fidalgo Bay all push marine air across the city on a regular basis. That air carries fine salt content that settles on exterior surfaces day after day. On metal fasteners, trim flashing, and any exposed wood substrate, salt exposure accelerates corrosion and speeds up the breakdown of paint films. Siding materials that rely on a factory or field-applied coating to keep moisture out are the ones that show this wear first, usually as chalking, fading, or fastener bleed-through long before the material itself has failed.
Driving rain and wind-driven moisture
Western Washington rain is rarely gentle straight-down rain. In an exposed, waterfront-adjacent town like Anacortes, wind pushes rain sideways into walls, especially on west- and south-facing elevations and around window and door openings. That means siding here has to shed water horizontally, not just vertically, and every seam, joint, and penetration needs to be detailed as if it will get hit directly by wind-driven water — because it will.
The long moss and algae season
Skagit County's wet season stretches long, and Old Town Anacortes' older tree cover and close-set lots mean a lot of siding sits in partial shade for much of the year. That combination of moisture and shade is exactly what moss and algae need to take hold. On porous or wood-based siding, moss growth holds moisture against the substrate and accelerates rot from the inside out. On siding with a poor factory finish, algae staining becomes a recurring cosmetic problem that no amount of pressure washing permanently solves.
Why Fiber Cement Fits This Neighborhood
Character without the maintenance trap
Old Town Anacortes has a mix of architectural styles — older cottages, craftsman-influenced homes, and mid-century infill — and homeowners here are often trying to preserve a certain look rather than modernize it away. Fiber cement siding takes paint and texture well enough to match traditional lap profiles and trim details, so you don't have to trade the neighborhood's character for weather resistance.
Non-combustible and dimensionally stable
Fiber cement doesn't expand and contract with moisture and temperature swings the way wood does, and it won't ignite from a stray ember or nearby brush fire the way wood or vinyl-based products can. In a marine climate where wall assemblies are already absorbing more moisture cycling than an inland home would see, that dimensional stability matters — it's less filler cracking, less paint failure at the joints, and less chance of the siding itself becoming the source of a moisture problem.
What a Correct Installation Actually Involves Here
Product line selection
James Hardie makes climate-engineered product lines for a reason. For Anacortes and the rest of the Skagit County coastline, that means specifying the HZ5 line, engineered for wetter, harsher climates, rather than a generic version meant for drier inland regions. Getting this specification right up front is a small decision that has a large effect on long-term performance.
Flashing and moisture management first, siding second
Siding is the last layer in a wall system, not the whole system. Before a single piece of Hardie board goes up, the water-resistive barrier, window and door flashing, and drainage plane behind the siding need to be correct. On a marine-exposed, rain-driven site like Old Town Anacortes, we pay particular attention to head flashing above openings, kick-out flashing at roof-to-wall intersections, and a drainage gap that lets any moisture that does get behind the siding drain and dry out rather than sit against the wall sheathing.
Fastening, clearances, and joints
Fiber cement has to be fastened according to manufacturer specification — correct nail or screw type, correct spacing, and no over-driving, which can crack the board or compromise its water resistance at the fastener. Ground clearance and roof-line clearance matter too: siding installed too close to grade, a deck, or a roof surface holds moisture against the bottom edge of the board and invites the exact rot and staining problems homeowners are trying to avoid in the first place. Butt joints and inside/outside corners get properly caulked and, where called for, flashed — not just butted together and painted over.
Our Process for an Old Town Anacortes Project
- On-site assessment — we look at the existing siding, the wall assembly behind it where accessible, moisture staining patterns, and the specific exposure of each elevation to prevailing wind and rain.
- Scope and product plan — we specify the correct Hardie product line, profile, and ColorPlus or field-paint finish based on the home's style and the homeowner's preference.
- Tear-off and substrate check — old siding comes off and we inspect sheathing for hidden rot or moisture damage before anything new goes up, since covering a wet substrate defeats the purpose of a new install.
- Water-resistive barrier and flashing — house wrap, flashing, and drainage details get installed or corrected before siding starts.
- Installation to manufacturer spec — fastening, clearances, and joint treatment done to Hardie's published installation requirements, not shortcuts.
- Final detailing and walkthrough — trim, caulking, and touch-up paint reviewed with the homeowner before we call the job done.
Fiber Cement Compared to Other Siding Options
| Factor | James Hardie Fiber Cement | Vinyl | Wood / Cedar |
|---|---|---|---|
| Salt air resistance | Strong; factory finish resists chalking and fade | Can become brittle and discolored over time | Vulnerable without diligent, repeated sealing |
| Moss/algae resistance | Good with proper drainage detailing | Traps moisture behind panels if installed poorly | Prone to holding moisture and feeding rot |
| Fire resistance | Non-combustible | Can melt or deform near heat sources | Combustible |
| Maintenance | Occasional wash, repaint only if field-finished | Low maintenance but limited repair options | Regular sealing, painting, and spot repair |
| Longevity when installed to spec | Decades, backed by transferable warranty | Variable; seams and fasteners weather first | Shorter without consistent upkeep |
This isn't a knock on every other product on the market — it's the reason our crew standardized on one system we can install correctly and stand behind, rather than juggling multiple product lines with different failure points.
Signs Your Old Town Anacortes Home May Already Need New Siding
- Paint that's chalking, peeling, or fading faster than it used to, especially on west- or south-facing walls
- Dark streaking or persistent moss/algae growth that comes back within weeks of cleaning
- Soft spots, bubbling, or visible warping near the bottom courses of siding
- Rust streaks running down from fasteners or trim
- Gaps opening up at butt joints, corners, or around window and door trim
- A musty smell or visible staining on interior walls that share an exterior wall with a suspect area
Any one of these on its own might be minor. Several together, especially on a home that's had multiple repaints, usually means the siding is past the point where another coat of paint solves the problem.
Cost Factors Worth Understanding Before You Get Quotes
Every Old Town Anacortes home is a little different, but a few factors consistently move the price of a fiber cement project:
- Substrate condition — hidden rot found after tear-off adds repair work that a surface-level quote can't predict
- Home size and elevation complexity — homes with lots of corners, dormers, or trim detail take more labor per square foot than a simple rectangular wall
- Product finish — factory-applied ColorPlus finish costs more up front than field paint but saves on repainting over the life of the siding
- Access — tight lots, close-set neighboring homes, and limited staging area (common in this older part of town) can add time to a project
- Existing siding removal — full tear-off versus siding over an existing layer, where code and condition allow it
We don't publish blanket price lists because these variables genuinely change the number — but we'll walk your specific home with you and explain exactly what's driving your estimate before you commit to anything.
Why Hiring a Crew That Already Works Old Town Anacortes Matters
A crew that regularly works this neighborhood already understands the exposure patterns of these lots, the age range of the housing stock, and the kind of moisture problems that show up behind older siding here. That's not a substitute for a proper on-site assessment of your specific home, but it does mean fewer surprises and a crew that isn't guessing at how Anacortes' marine climate behaves against a wall. We install James Hardie fiber cement exclusively because it's the one system we're confident holds up to salt air, driving rain, and a long moss season when it's installed the way the manufacturer specifies — not shortcut, not improvised.
