Anacortes Exterior Why Old Town Anacortes Homes Wear Differently
Old Town Anacortes is one of the older residential pockets on Fidalgo Island, and the housing stock shows it. Many of these homes were built well before modern weather-resistive barriers, rain-screen gaps, or engineered flashing details were standard practice. That's not a knock on the original builders — it's just a different era of construction. When we replace siding here, we're rarely dealing with a simple like-for-like swap. We're usually correcting decades of moisture exposure that the original assembly was never designed to handle.
Add in the marine climate that defines this part of Skagit County — salt-laden air off the water, long stretches of driving rain, and a moss season that can run most of the year in shaded yards — and you have a set of conditions that ages siding faster here than it would forty miles inland. A siding replacement done right in Old Town Anacortes has to account for all of that, not just cover it up with new material.
What's Really Going On Behind Older Siding
Hidden moisture damage
On homes of this vintage, we often find sheathing that's absorbed years of moisture through nail penetrations, poorly lapped seams, or missing kick-out flashing at roof-to-wall intersections. From the street, the siding might look fine. Once it comes off, it's common to find soft or delaminated sheathing, rusted fasteners, and in some cases framing that needs repair before any new siding goes up.
Older siding materials
Depending on when a home in Old Town Anacortes was last re-sided, we sometimes encounter older cement-asbestos siding products from decades past. If we suspect that's what we're dealing with, we don't guess — we recommend proper testing and handling before tear-off begins. This isn't a scare tactic; it's standard, responsible practice on older housing stock anywhere in the country, and it protects everyone on the property.
No drainage plane
A lot of older siding was installed directly against the sheathing with no drainage gap and, in some cases, no continuous weather barrier at all. In a climate that gets as much sustained rain as this one does, that's the single biggest reason old siding fails from the inside out rather than the outside in.
The Salt Air and Moss Factor
Anacortes sits right on the water, and that proximity matters more for siding than most homeowners realize. Salt air accelerates corrosion on exposed fasteners, staples, and any metal flashing that isn't properly coated. Over enough years, that corrosion works its way into the siding attachment points themselves, which is part of why we see premature failure on homes that otherwise look well maintained.
Moss is the other constant. Mature trees and close-set lots in Old Town Anacortes mean plenty of shaded, slow-drying wall sections, especially on north- and east-facing exposures. Moss and algae hold moisture against the siding surface far longer than open, sun-exposed walls ever see, which shortens the life of paint film and accelerates rot on wood-based products in particular.
What a Correct Siding Replacement Involves
A proper siding replacement is not just pulling off the old boards and nailing up new ones. On an older Old Town Anacortes home, the job should include:
- Full tear-off and inspection of the sheathing underneath, with repair or replacement of any damaged sections before new material goes on
- Installation of a continuous, properly lapped weather-resistive barrier, correctly integrated with window and door flashing
- Corrosion-resistant fasteners rated for the coastal environment, not standard interior-grade hardware
- Correct flashing at every roof-to-wall transition, deck ledger, and penetration — the details that actually stop water, not just the siding itself
- Manufacturer-specified nailing patterns, clearances, and joint treatment so the warranty on the new siding actually holds up
Skipping any one of these steps is how a brand-new siding job ends up with the same moisture problems in ten years that the old siding had after forty.
Why We Install Only James Hardie Fiber Cement
We don't install vinyl, LP SmartSide, primed spruce, cedar, or other fiber cement brands. That's a deliberate standard, not a default. Vinyl expands and contracts with temperature swings and can warp or crack in impact-prone spots; it also traps moisture behind it if the install isn't flawless. Wood-based products — including engineered wood siding — depend on an unbroken paint or coating layer to keep moisture out, which is a hard promise to keep in a climate with this much sustained rain and moss pressure. Cedar and primed spruce need more frequent maintenance than most homeowners realize going in, and any lapse in upkeep shows up fast on a shaded, salt-exposed wall.
James Hardie fiber cement is non-combustible, dimensionally stable, and built in HZ product lines engineered specifically for wetter, marine-influenced climates like this one. The factory-applied ColorPlus finish resists fading and holds up to the kind of driving rain and salt air Anacortes sees, and it comes with a strong, transferable warranty backed by a manufacturer with decades of track record in coastal Pacific Northwest markets. It's not the cheapest material on the shelf, but it's the one we're willing to put our name behind after seeing how older siding actually performs in this exact climate, year after year.
HardiePlank vs. HardiePanel
Most homes in Old Town Anacortes are good candidates for HardiePlank lap siding, which mimics traditional wood lap siding and suits the older architectural character common in this neighborhood. HardiePanel, a vertical sheet product, comes into play more on accent walls, gable ends, or homes with a more modern detailing. Which one — or which combination — makes sense depends on the home's existing lines and how it's transitioning at trim, corners, and window surrounds.
Our Process for Old Town Anacortes Projects
Working in an established neighborhood like this one comes with practical realities that a generic siding crew might not plan for. Lots here tend to be smaller and closer together, driveways and street parking are tighter, and mature landscaping often needs to be protected or worked around rather than cleared. We scope for that up front — where material gets staged, how debris comes off the property without damaging fences or gardens, and how we keep a job site tidy on a street where neighbors are close by.
We also pay attention to the character of the home itself. A lot of Old Town Anacortes houses have trim details, porch elements, or proportions worth respecting rather than flattening out with a generic re-side. Our process includes a full exterior walkthrough, moisture and rot assessment, a written scope before any tear-off starts, and a clear sequence for sheathing repair, weather barrier installation, flashing, and Hardie installation — so there are no surprises once the old siding is off the wall.
Cost Factors for Siding Replacement in This Area
| Factor | Why It Matters in Old Town Anacortes | Effect on the Project |
|---|---|---|
| Sheathing condition | Older homes often have hidden moisture damage behind original siding | Can add repair scope not visible until tear-off |
| Access and lot size | Tighter lots and street parking limit staging and equipment access | May affect scheduling and material handling |
| Trim and architectural detail | Older homes often have more window, corner, and porch trim to work around | More labor-intensive than a simple flat wall re-side |
| Number of stories and roof lines | Multiple roof-to-wall transitions need correct flashing | Adds flashing detail work, not just siding panels |
| Existing moss or algae staining | Common on shaded, tree-covered lots near the water | May require additional prep or wall washing before install |
Every home is different, which is why we walk the property and give a specific scope rather than a generic square-footage number pulled from a phone call.
Maintenance After Replacement
James Hardie siding is low-maintenance compared to wood or vinyl, but "low-maintenance" doesn't mean "no maintenance," especially in a coastal, moss-prone environment. A short annual routine keeps a new install performing the way it's designed to:
- Rinse siding gently once or twice a year to clear salt residue and early moss or algae growth, especially on shaded walls
- Keep gutters clear so overflow doesn't run down the wall face and sit against the siding
- Trim back tree limbs and shrubs that keep a wall section damp and shaded longer than the rest of the house
- Check caulking at trim, window, and door joints every couple of years and re-seal if it's cracked or pulling away
- Walk the exterior after major storms to check for any impact damage or loosened trim
Choosing a Contractor Who Knows This Neighborhood
Siding replacement is one of those jobs where the difference between a good result and a bad one is almost entirely in details you can't see from the curb — the flashing, the weather barrier lap, the fastener choice, the sheathing underneath. A contractor who has actually worked on Old Town Anacortes homes has seen what this specific combination of age, moisture, salt air, and shade does to a wall assembly, and knows what to check for before the first board comes off. That experience shows up in fewer surprises mid-project and a finished job that's built for the climate it actually has to survive, not a generic one.
