Anacortes Siding Siding Built for the Old Town Anacortes Waterfront
Old Town Anacortes sits close to the water, which means its homes take a different kind of weathering than houses further inland in Skagit County. Salt-laden air off the Guemes Channel and Fidalgo Bay works on exposed fasteners and cut edges year-round, not just during storms. Add in Anacortes's driving winter rain, which tends to come in sideways off the water rather than straight down, and a long, damp moss season that can stretch from late fall into spring, and you have a combination that punishes siding systems that weren't built with coastal exposure in mind.
Many homes in this part of Anacortes are older — a mix of early-to-mid-century construction and later infill — which means the existing siding, trim, and water-resistive barrier underneath it were often installed to a different standard than we'd use today. When we're called out for a siding replacement in Old Town, we're rarely just swapping one material for another. We're usually also correcting drainage details, fastener choices, and clearances that were fine for their era but don't hold up to another 30 years of Anacortes weather.
Why Salt Air, Driving Rain, and Moss Season Matter Here
Salt Air and Metal Fasteners
Airborne salt accelerates corrosion on any exposed metal — nail heads, trim flashing, hose bibs, light fixture penetrations. Over years, corroding fasteners can streak siding, loosen boards, and create small gaps where water gets behind the cladding. A correct installation in a salt-air environment means using corrosion-resistant fasteners rated for the exposure, not whatever was cheapest at the yard.
Driving Rain and Wind-Driven Moisture
Anacortes storms frequently push rain horizontally, which puts far more pressure on lap joints, butt seams, and penetrations (hose bibs, vents, light fixtures) than a straight-down rain would. Siding that relies on caulk alone to keep water out at these points tends to fail first in exactly this kind of weather.
Moss and Prolonged Dampness
Skagit County's moss season isn't just a roof problem. Moss and algae growth on north-facing and shaded siding walls holds moisture against the surface for extended periods. Materials that are sensitive to sustained moisture exposure — through swelling, delamination, or paint failure — show it first on these walls.
What a Correct Siding Installation Actually Involves
The siding itself is only part of the system. What's underneath it, and how the pieces are detailed together, determines whether a siding job lasts 10 years or 40. On every Old Town Anacortes project, our installation includes:
- A continuous, correctly lapped water-resistive barrier (WRB) installed shingle-style so water sheds outward, never inward
- Proper flashing at every window, door, and penetration, integrated with the WRB rather than just caulked over the top
- Rainscreen or drainage gap detailing where conditions call for it, so any moisture that does get behind the cladding can drain and dry
- Correct fastener type, spacing, and embedment for the specific Hardie product being installed
- Manufacturer-specified clearances from grade, roof lines, and decks — a common failure point on older Anacortes homes where siding was run too close to the ground or a roof transition
- Factory-finished trim and starter strips, sealed and caulked only where the manufacturer's install instructions call for it
Skipping any one of these doesn't necessarily show up right away. It shows up in year six or year ten, as bubbling paint, soft trim, or streaking at fastener heads — problems that are far more expensive to fix once they're behind finished siding.
Why We Install Only James Hardie Fiber Cement
We standardized on James Hardie fiber cement siding for every project we take on, including in Old Town Anacortes, and we don't install vinyl, LP SmartSide, or other fiber cement brands. That's a deliberate choice, not a sales pitch. Hardie's fiber cement is non-combustible, dimensionally stable in wet-dry cycling, and available in HZ5 formulations engineered for cold, wet, coastal climates like ours. The ColorPlus factory finish is baked on under controlled conditions, which holds up better against salt air and UV exposure than field-applied paint, and it carries a strong, transferable warranty when installed to Hardie's specifications.
None of that replaces correct installation — a great product installed with the wrong flashing details will still fail. But it gives us a material we're confident recommending for exactly the kind of exposure Old Town Anacortes homes deal with, and it's the only fiber cement system we put our name behind.
Our Process for an Old Town Anacortes Siding Replacement
1. On-Site Assessment
We walk the exterior, check the current siding and trim condition, look at existing flashing and drainage details, and note any areas with moss growth, staining, or soft wood that indicate past moisture intrusion.
2. Removal and Substrate Check
Once old siding is off, we inspect the sheathing and framing underneath. Any rot or water damage gets addressed before anything new goes on — installing new siding over a compromised substrate just hides the problem.
3. Water-Resistive Barrier and Flashing
We install a continuous WRB and flash every penetration and transition before the first piece of siding goes up. This is the step that determines how the whole system performs in driving rain.
4. Hardie Installation
Siding, trim, and accessories go on per James Hardie's published installation instructions — correct fastener spacing, clearances, and joint treatment specific to the product line selected.
5. Final Walkthrough
We review the finished exterior with the homeowner, checking caulking, trim reveals, and paint touch-up at cut ends before calling the job complete.
Comparing Siding Approaches for Old Town Anacortes Conditions
| Factor | James Hardie Fiber Cement (HZ5) | Vinyl | Wood / Engineered Wood |
|---|---|---|---|
| Salt air resistance | Strong — factory finish, non-corrosive substrate | Can become brittle over time in coastal exposure | Vulnerable without diligent maintenance |
| Driving rain performance | Strong when flashed and lapped correctly | Prone to gapping at seams over time | Dependent on paint and sealant upkeep |
| Moss/moisture tolerance | Dimensionally stable, resists swelling | Doesn't rot, but traps moisture behind it if not vented | Susceptible to swelling and delamination if wet repeatedly |
| Fire resistance | Non-combustible | Combustible | Combustible |
| Finish longevity | Factory ColorPlus finish, long repaint interval | Color molded in, can fade | Field-applied paint, shorter repaint interval |
What Siding Replacement Costs Depend On
We don't publish flat prices because every Old Town Anacortes home is different, but the factors that move the number are consistent:
| Factor | Why It Matters |
|---|---|
| Substrate condition | Rot or water damage found after tear-off adds repair scope before new siding can go on |
| Home size and complexity | More corners, dormers, and roof transitions mean more flashing and trim detail work |
| Siding profile chosen | Lap, shingle, and panel Hardie products differ in material and labor cost |
| Existing drainage details | Adding rainscreen detailing where it's missing improves performance but adds labor |
| Access and site conditions | Tight lots, landscaping, or waterfront exposure can affect staging and scheduling |
We walk every factor through with homeowners during the estimate so there are no surprises once work starts.
Signs Your Old Town Anacortes Home May Need Siding Replacement
- Persistent moss or algae growth on siding, especially on shaded or north-facing walls
- Streaking or rust-colored staining below fastener heads or trim
- Soft or spongy siding or trim when pressed, especially near ground level or roof transitions
- Paint that's peeling, bubbling, or failing faster than expected on repainted surfaces
- Visible gaps opening up at lap joints or corner boards
- Warping, cupping, or separation of boards from the wall
- Interior signs like peeling paint or musty smell near exterior walls
Any one of these on its own isn't necessarily urgent, but a few appearing together, particularly on a home more than a few decades old, is usually a sign the siding system underneath has been letting water in for a while.
Why a Crew That Already Works in Old Town Anacortes Matters
A siding crew that's worked this specific stretch of Anacortes waterfront knows which walls take the worst of the wind-driven rain, how aggressively moss builds on shaded exposures here compared to more inland Skagit County properties, and what corrosion looks like on fasteners after just a few salt-air seasons. That local pattern recognition shapes real decisions on the job — where to add extra flashing attention, which walls justify rainscreen detailing, and what fastener spec actually holds up here rather than just on paper.
It also means fewer surprises during the estimate. We're not guessing at what Old Town's mix of older and newer construction typically hides behind the existing siding — we've seen it, and we plan for it up front.
