Anacortes Exterior Old Town Anacortes Homes Face a Tougher Siding Job Than Most
Old Town Anacortes is one of the older residential pockets in the city, and homes here carry decades of exposure that newer subdivisions simply haven't had time to accumulate. Many of these houses have already had one or two rounds of siding work done over their lifetime, sometimes well, sometimes as a quick patch job to get through another Skagit County winter. When we get called out to look at a siding replacement in this part of Anacortes, we're rarely dealing with a blank slate. We're dealing with a wall system that has a history, and that history matters for how the job gets done correctly.
Replacing siding on an older home near the water isn't the same project as siding a new-construction house on the edge of town. The framing, the sheathing, the original flashing details, and even the way the house was oriented to weather all factor into what a correct replacement looks like. Skipping that assessment is how a siding job looks fine for two years and then fails for reasons that had nothing to do with the new siding itself.
What Salt Air, Rain, and Moss Actually Do to Siding Here
Anacortes sits close enough to saltwater that airborne salt is a real factor in how exterior materials age, not just a talking point. Combined with the steady driving rain common to Skagit County winters and a moss season that can stretch for months on shaded, north-facing walls, siding here takes on moisture and organic growth at a rate that inland homes just don't experience.
- Salt air accelerates corrosion on exposed fasteners, trim, and any metal flashing that isn't properly protected or has started to fail.
- Driving rain, especially wind-driven rain off the water, pushes moisture into seams, laps, and joints that would stay dry in calmer weather.
- Extended moss and algae growth holds moisture against the siding surface far longer than a quick rain shower would, which is especially hard on wood-based products and older paint films.
None of these are exotic problems. They're just constant, low-grade stress that adds up over years. A siding product and installation detail that would hold up fine in a drier climate can wear out faster here simply because it never gets a chance to fully dry out between weather events.
Why Older Homes Need a Different Approach
Older homes in this part of Anacortes were often built before modern weather-resistive barriers, rainscreen gaps, and integrated flashing systems were standard practice. That doesn't mean they were built poorly for their time, but it does mean a straightforward "remove old siding, nail up new siding" approach can leave the same underlying moisture problems in place, just hidden behind a fresh face.
We've also found that many older homes have had siding replaced or repaired at least once already, sometimes with materials layered over each other rather than fully removed. That can mask rot, trapped moisture, or sheathing damage that isn't visible until the old layers come off. A correct replacement on a home like this starts with finding out what's actually happening under the surface, not just what the exterior looks like from the curb.
Common Issues We Find on Older Anacortes Homes
- Sheathing softened by long-term moisture intrusion behind old siding laps
- Missing or deteriorated flashing around windows, doors, and roof-to-wall transitions
- Multiple layers of old siding or trim built up over decades
- Paint films failing and trapping moisture against wood substrates
- Gaps or settling around foundation transitions common to older framing
What a Correct Siding Replacement Actually Involves
A proper siding replacement is a sequence, and skipping steps to save time is exactly how a job that looks good on installation day starts failing within a few wet seasons. For an Old Town Anacortes home, the sequence generally looks like this:
- Full removal of existing siding and inspection of the sheathing underneath
- Repair or replacement of any damaged sheathing, framing, or trim boards found during tear-off
- Installation of a proper weather-resistive barrier, lapped and sealed correctly at every seam
- Correct flashing at all windows, doors, and any roof-to-wall intersections
- Installation of the new siding to manufacturer specification, including proper fastening, clearances, and joint treatment
- Detailing of trim, corners, and caulking points designed to shed water rather than trap it
Every one of those steps matters more in a climate that gives siding less time to dry out. A house near the water with heavy moss exposure needs the water management details done right the first time, because the margin for error is smaller here than it is in a drier inland town.
Old Siding Materials We Commonly Encounter vs. What Replaces Them
| Existing Material Found | Typical Condition After Years of Exposure | What We Install Instead |
|---|---|---|
| Original wood lap siding | Paint failure, cupping, rot at butt joints and bottom edges | James Hardie fiber cement lap siding |
| Older aluminum or steel siding | Denting, fading, corrosion at fasteners near the water | James Hardie lap or panel siding |
| Vinyl siding added in a prior remodel | Warping, fading, brittleness in cold snaps | James Hardie ColorPlus lap siding |
| Patched or mixed materials from repairs | Inconsistent appearance, hidden moisture points at transitions | Full-wall Hardie system, consistent detailing |
Why We Install Only James Hardie Fiber Cement
We made a decision as a company to install James Hardie fiber cement siding exclusively, and we don't treat that as a marketing detail. It's a standard we hold ourselves to because of what we've seen happen to other materials in this exact climate. Fiber cement doesn't absorb water and swell the way wood-based products can, and it doesn't have the expansion and contraction behavior that causes vinyl to warp or pull away from trim in temperature swings. It's also non-combustible, which matters to homeowners regardless of siding brand.
James Hardie's HZ5 product line is engineered specifically for climates like ours, with wetter weather and more moisture exposure than the HZ10 line built for hot, dry regions. The factory-applied ColorPlus finish is baked on and warranted against fading and peeling in a way that field-applied paint on wood siding simply can't match, which matters on a home getting constant rain and salt air. We don't install LP SmartSide, vinyl, cedar, or other fiber cement brands, not because those products have no merit anywhere, but because we've standardized on the one system we trust to hold up on Anacortes homes for the long haul, backed by a strong transferable warranty if the home changes hands.
Our Process for Old Town Anacortes Projects
Every project starts with an in-person walk-around of the home, not a drive-by estimate. We look at the current siding condition, check for soft spots and moisture signs, and take note of anything specific to the home's age, orientation, and exposure to weather. From there we put together a clear scope: what's being removed, what repairs are needed underneath, and exactly which Hardie products and colors fit the home.
During the job, we handle the tear-off carefully so we can properly assess the sheathing rather than just covering it back up. Any rot or damage gets addressed before a single piece of new siding goes up. We install the weather barrier and flashing details to spec, then install the Hardie siding itself with the fastening, clearances, and joint treatment the manufacturer requires to keep the warranty valid. We finish with trim and caulking details built to shed water, which matters more on a home taking on driving rain off the water than it does further inland.
Cost Factors for Older Home Siding Replacement
Costs vary based on the home's size, current condition, and how much repair work is needed underneath the old siding, so we don't quote a number without seeing the house. What we can tell you is what tends to move the price up or down on projects like these.
| Factor | Why It Matters |
|---|---|
| Extent of hidden sheathing or framing damage | Older homes with a history of moisture intrusion often need repair work before new siding goes up |
| Number of layers of existing siding | Multiple layers take longer to remove and dispose of than a single layer |
| Trim and detail complexity | Older architectural details often require more custom trim work than a simple modern facade |
| Siding profile and color selection | Certain Hardie profiles and premium ColorPlus shades carry different material costs |
| Access and site conditions | Tight lots, mature landscaping, or multi-story sections can affect labor time |
Signs Your Old Town Anacortes Home May Need Replacement Now
- Paint that keeps failing within a year or two of repainting
- Soft or spongy spots when you press on the siding, especially near the bottom edges
- Visible cracking, warping, or buckling in the existing siding
- Persistent moss or algae staining that comes back quickly after cleaning
- Gaps opening up at trim, corners, or window and door surrounds
- Rising energy bills that may point to moisture-compromised insulation behind the siding
Why Local Experience in Old Town Anacortes Matters
A crew that regularly works in this part of Anacortes has already seen how the local combination of salt air, rain exposure, and moss affects older homes specifically, not siding in general. That experience shows up in the details: knowing where water tends to collect on homes with this style of construction, understanding what to expect once old siding comes off an older wall, and being able to spot which repairs are genuinely needed versus which are just upselling. It also means showing up reliably for a multi-day project in a neighborhood where homes are close together and weather windows can be tight.
