Anacortes Window Siding Built for Old Town Anacortes
Old Town Anacortes is the original core of the city — a walkable pocket of older homes close to the water, many of them built long before anyone was thinking about rain screens, factory-applied finishes, or engineered climate ratings for exterior siding. That's not a knock on the neighborhood. It's the reason siding work here is different from a subdivision re-side on the edge of town. These houses have already been through decades of exposure, and whatever goes back on the walls next has to hold up to the same conditions that wore out what's there now, plus another twenty or thirty years on top of it.
We install James Hardie fiber cement siding, exclusively, and this page is about what that looks like specifically for a home in Old Town Anacortes: what the local climate demands, what a correct installation actually involves on an older structure, and why the crew doing the work matters as much as the product itself.
What This Climate Actually Does to a Wall
Anacortes sits on Fidalgo Island, surrounded by marine water on nearly every side, and Old Town's proximity to that water means the exterior of every home here is dealing with a specific combination of stressors: salt-laden air, wind-driven rain, and a moss and mildew season that runs most of the year. None of the three is unusual by itself for western Skagit County. Together, over a couple of decades, they're a harder test on a wall than a lot of siding products were ever built to pass.
Salt Air Off the Water
Airborne salt accelerates the breakdown of paint films and speeds up corrosion on fasteners, flashing, and trim hardware. A finish that holds up fine in a drier inland town doesn't necessarily get the same service life a few blocks from Anacortes's waterfront, and that difference usually shows up slowly — as chalking, fading, or fastener staining — rather than as a sudden, obvious failure.
Wind-Driven Rain
Rain here rarely falls straight down. Wind off the water pushes it sideways, into lap joints, under trim boards, and into any seam where the water-management detailing isn't right. That's a much tougher test for caulked joints and painted surfaces than a simple annual rainfall number would suggest, and it's a big part of why installation detail matters as much as the siding material itself.
A Moss Season That Doesn't Really End
Mild temperatures and near-constant moisture mean moss and mildew stay active across most of the calendar, especially on shaded, tree-lined lots — common in Old Town, where mature trees and tight lot spacing keep walls damp longer after a rain. Organic growth on a siding surface traps moisture against the wall behind it, and that trapped moisture is where a lot of long-term siding failures actually start, regardless of the material.
The Extra Layer With Older Old Town Homes
A siding job in Old Town Anacortes isn't just a material swap. Many of these homes have original wall assemblies, older framing, and trim details that a newer subdivision house doesn't have, and all of that has to be respected or corrected as part of the work.
What's Usually Hiding Under the Old Siding
On a home this age, we plan for the likelihood of finding something once the old siding comes off: soft or delaminated sheathing, past water intrusion around windows or roof-to-wall transitions, or wiring and venting that was never sealed correctly the first time. A rushed crew ignores this or treats it as a change-order surprise. A crew that expects it builds the inspection into the process from the start and gives you a straight answer about what's actually there before closing the wall back up.
Trim, Corners, and Original Proportions
Older Anacortes homes often have narrower trim reveals, distinct corner details, and window and door proportions that don't match a modern production-built house. Matching those proportions with Hardie trim and siding profiles takes more layout planning than a straightforward new-construction install, and it's the difference between a re-side that looks like it belongs on the house and one that visibly doesn't.
Why We Only Install James Hardie Fiber Cement Here
We don't install vinyl, LP SmartSide or other engineered wood products, cedar, or primed spruce, and that's a deliberate standard, not a limited product list. Vinyl's lapped, unsealed joints and heat sensitivity aren't a good match for wind-driven rain and the temperature swings this coastal exposure can bring. Engineered wood and traditional wood siding both depend on a factory or field coating and every cut edge staying sealed indefinitely — a heavy maintenance burden in a climate where wet weather is the default, not the exception. James Hardie fiber cement is an inorganic material: a cured blend of cement, sand, and cellulose fiber that doesn't have a wood-based or foam core to absorb water, swell, or feed insects, and it's non-combustible.
HZ5 Engineering for This Region
Hardie engineers its siding by climate zone, and the HZ5 line is built for regions with sustained moisture exposure and freeze-thaw cycles — a closer match to Skagit County's winters than a product line engineered primarily for hot, dry regions. That's a concrete, verifiable reason we standardized on this manufacturer rather than fiber cement as a generic category.
ColorPlus Factory Finish
Rather than relying on a coat of paint applied on site, Hardie's ColorPlus finish is baked on in multiple coats under controlled factory conditions before the boards ever arrive at the house. It carries its own finish warranty, separate from the substrate warranty, and it's formulated specifically to resist the fading and chalking that salt air and UV exposure cause faster near the water.
Long-Term Maintenance
Once installed, Hardie siding doesn't need periodic repainting or recaulking the way a wood-based product does. Homeowners still need to keep gutters clear, trim back vegetation that shades and dampens the wall, and rinse off accumulated grime or moss growth occasionally — but that's routine upkeep, not the recurring maintenance schedule an organic or wood-fiber product requires to keep its protective coating intact.
What a Correct Installation Involves
Fiber cement's real-world performance depends heavily on installation quality — the material can only do its job if the details around it are right. This is what we hold every Old Town job to:
| Installation Detail | Why It Matters on an Old Town Home |
|---|---|
| Manufacturer clearances at grade, roofline, and decks | Keeps splash-back and standing moisture off the board edge, especially on older lots with less grading room |
| Correct fastener type, spacing, and depth | Prevents cracking and keeps the water-resistive barrier behind the siding intact |
| Flashing at every window, door, and roof-wall transition | Directs wind-driven rain away from seams instead of letting it collect at old, often re-flashed openings |
| Rain screen or drainage gap behind the siding | Lets moisture that gets past the surface drain and dry instead of sitting against original sheathing |
| Factory-cut edges used wherever the layout allows; field cuts sealed to spec | Preserves the factory finish's protection at every joint, corner, and trim return |
| Trim and reveal widths matched to the home's original proportions | Keeps the finished look consistent with the house's age and style instead of a generic modern reveal |
Our Process, Start to Finish
The steps are the same on every Hardie install we do, but on an older Old Town home, the early steps carry more weight because they're where the surprises usually show up.
- Site walk and estimate. We look at the existing siding, trim, and any visible signs of past water intrusion, and give you a straight assessment of scope before any contract is signed.
- Tear-off and sheathing inspection. Once the old siding is off, we inspect the sheathing and framing underneath and flag anything that needs repair before new siding goes on — with real numbers, not a vague allowance.
- Water-resistive barrier and rain screen installation. This is the layer that does the quiet work of managing moisture behind the siding for the life of the wall.
- Hardie siding and trim installation to manufacturer spec. Clearances, fastening, and flashing are done to the HZ5 spec, not adjusted on the fly to save time.
- Caulking, touch-up, and final detailing. Seams, trim returns, and any field-cut edges are sealed correctly before we call the job finished.
- Final walk-through. We go over the finished work with you directly and answer whatever questions come up before we consider the job done.
Cost Factors for an Old Town Siding Project
Every project is different, and we don't quote firm numbers without seeing the house, but these are the factors that most often move a bid up or down on an older Old Town home specifically.
| Factor | How It Affects the Project |
|---|---|
| Condition of sheathing and framing under the old siding | Hidden repair needs are more common on older homes and are usually the biggest source of change in scope |
| Trim complexity and matching original proportions | Custom trim layout takes more labor time than a standard modern reveal |
| Lot access and staging space | Tighter, older lots can slow material staging and require more hand-carrying versus machine access |
| Scope: full re-side versus partial or accent areas | Partial projects still require careful transition detailing where new siding meets existing material |
| Siding profile and ColorPlus color selection | Lap width, panel style, and finish choice affect material cost and how the home reads architecturally |
Choosing a Crew That Actually Works This Neighborhood
Old Town Anacortes rewards a contractor who's done this specific kind of house before — one who isn't guessing at what's behind original siding or improvising trim proportions on the fly. Before you hire anyone for a project like this, it's worth confirming:
- They're a manufacturer-certified James Hardie installer, not just generally experienced with siding.
- They can explain, specifically, how they'll handle sheathing repair if it turns up once the old siding is removed.
- They have a clear plan for matching trim reveals and corner details to the home's existing proportions.
- They carry current WA contractor licensing and liability insurance, and can produce it without hesitation.
- They give you a written scope that separates the base install from any conditional repair work, so a change order isn't a surprise.
- They'll walk you through the manufacturer's warranty terms, including what's covered on the substrate versus the ColorPlus finish.
