Windows in Old Town Anacortes Face a Different Kind of Wear
Old Town Anacortes is one of the older residential pockets of the city, with a mix of early-1900s homes and later infill sitting close to the water. Houses here were mostly built long before double-pane glass, weather-resistive barriers, and modern flashing details were standard practice. That means a lot of the original or early-replacement windows in this neighborhood are working against conditions they were never designed for.
Being this close to Rosario Strait and the greater Salish Sea marine environment means constant exposure to salt-laden air, wind-driven rain that hits window walls at an angle instead of straight down, and a moss and algae season that stretches for much of the year in the Pacific Northwest's wet, mild climate. None of that is unique to any one house — it's the baseline every window on a home in this part of Anacortes has to stand up to, year after year.

What Salt Air, Rain, and Moss Actually Do to a Window
Salt Air and Metal Components
Salt air accelerates corrosion on anything metal — window hardware, screen frames, and especially older aluminum sash or aluminum storm windows. Once corrosion starts on hinges, locks, or balance mechanisms, windows get harder to open and close, and the seals around them stop doing their job even if the glass itself still looks fine.
Driving Rain and Water Intrusion
Skagit County storms regularly push rain sideways, not straight down. On older homes, that means water gets tested against seams, sills, and trim joints that were sealed decades ago and were never built with a modern drainage plane behind them. Once water finds a path behind old trim or through a failed sill, it can sit in wall framing far longer than it would in a drier climate, because our air rarely gives wood a real chance to dry out.
Moss, Algae, and Prolonged Dampness
A long moss season isn't just a roof problem. On north-facing and shaded walls, algae and moss growth on siding and trim around windows holds moisture against the wood far longer than open, sun-exposed walls. That constant dampness is what eventually rots sills, sashes, and the trim boards that frame a window opening.
Signs an Old Town Home's Windows Need Attention
Most window problems in this neighborhood show up gradually, and homeowners often adjust to them without realizing how much has changed. Here's what we look for, and what you can check yourself:
- Windows that are difficult to open, close, or lock — often a sign of swollen frames or corroded hardware
- Visible gaps between the sash and frame, or daylight showing around the edges
- Soft or spongy wood at the sill, especially on the exterior face
- Condensation building up between panes of double-glazed units — a sign the seal has failed
- Peeling or bubbling paint on interior trim near the window, which often points to moisture getting in from outside
- A noticeable draft or cold spot near the window on windy days
- Visible moss, algae, or dark staining on exterior trim or sills
- Noticeably higher heating bills without another clear explanation
Any one of these on its own might not mean much. Several together, especially on the weather-facing side of the house, usually mean the window and the wall around it need a closer look, not just a new pane of glass.
Choosing Window Materials for This Climate
Material choice matters more here than in a drier, inland climate, because whatever you install is going to sit in salt air and near-constant humidity for its entire service life. There's no single "best" material for every home — it depends on your budget, your home's style, and how much upkeep you want to take on.
| Material | How It Handles This Climate | Trade-Offs to Know |
|---|---|---|
| Vinyl | Won't rot or corrode; handles moisture well with no painting needed | Limited custom color and profile options; can look out of place on older architectural styles if not detailed carefully |
| Fiberglass | Very stable in temperature swings and resists moisture better than wood; holds paint well if a custom color is needed | Higher upfront cost than vinyl |
| Wood (with cladding) | Matches historic and craftsman detailing best; exterior cladding shields the wood from direct weather | Interior wood still needs periodic maintenance; any breach in the cladding lets moisture reach the wood underneath |
| Aluminum | Strong and slim sightlines | Prone to corrosion in salt air unless properly finished and maintained; conducts cold, which shows up as condensation in our damp winters |
Because of how aluminum performs in marine air over time, and how much upkeep exposed, uncladded wood requires here, we generally steer Old Town customers toward vinyl, fiberglass, or clad-wood options depending on how closely they want to match the home's original look. We'll walk through the honest trade-offs for your specific house rather than pushing one material for every project.
Matching New Windows to an Older Home's Character
Custom Sizing Is the Norm, Not the Exception
Very few window openings in this part of Anacortes match today's standard manufacturer sizes. Homes here were framed by hand, openings settle over the decades, and prior repairs sometimes altered the rough opening slightly. That's exactly why "custom windows" isn't a marketing phrase for this neighborhood — it's usually the only way to get a proper, tight-fitting install without tearing into more of the wall than necessary.
Keeping the Right Look
Grid patterns, sash proportions, and trim profiles all matter for keeping an older home looking like itself. A window that's technically well-built but has the wrong grid pattern or a bulky modern profile can throw off the whole front elevation. We match sightlines and proportions to the existing house, not just the opening dimensions.
How We Approach a Custom Window Project
1. On-Site Assessment
We start by looking at the existing windows, the condition of the framing around them, and any signs of past water intrusion — not just measuring for new glass. On an older home, what's happening inside the wall matters as much as what the window looks like from the street.
2. Precise Measurement and Ordering
Because openings are rarely standard sizes, we measure each opening individually rather than assuming uniformity across the house, even for windows that look identical from outside.
3. Removal and Opening Prep
Old sashes and frames come out carefully so we can inspect the sill, header, and side jambs for rot or damage before anything new goes in. Any compromised wood gets replaced now — sealing new windows into a wet or rotten opening just hides the problem for a few years instead of fixing it.
4. Flashing and Moisture Barrier Detail
This is the step that matters most in our climate and the one that's easiest to shortcut. Proper flashing tape and drainage planes around each opening give wind-driven rain a path to shed away from the wall instead of behind it. We treat this step as non-negotiable, regardless of how good the window itself is.
5. Installation and Sealing
Windows get set plumb, level, and square, shimmed and fastened per manufacturer specs, then sealed with exterior-grade sealant rated for our wet, salt-air conditions rather than a generic caulk.
6. Trim, Cleanup, and Walkthrough
We finish or replace exterior trim to match the home's existing profile, clean up the work area, and walk through the finished windows with you before we consider the job done.
What Affects the Cost of a Custom Window Project
Every home in Old Town Anacortes is a little different, so costs vary. These are the factors that move the price up or down, so you know what you're actually paying for when you compare quotes.
| Factor | Why It Matters |
|---|---|
| Number and size of openings | More or larger windows means more material and labor |
| Material selected | Vinyl, fiberglass, and clad-wood carry different unit costs |
| Condition of the existing opening | Rot repair or reframing adds time and material beyond the window itself |
| Access and height | Second-story or hard-to-reach openings take longer and may need additional equipment |
| Trim and exterior finish work | Matching existing profiles or repainting trim adds labor |
| Grid pattern and glass options | Custom grids, tinted, or upgraded glass packages cost more than standard clear double-pane |
Beware of quotes that are dramatically lower than everyone else's — it usually means either the flashing and moisture-barrier work is being skipped, or a lower-grade window is being substituted without you knowing.
Why Hiring a Crew That Already Works in Old Town Anacortes Matters
A contractor who works this neighborhood regularly already understands how this area's homes were built, how salt air and driving rain behave against them, and what tends to go wrong when a window job skips steps. That's different from a crew that mostly works newer construction across the county and treats every job the same way.
Local experience also means fewer surprises mid-project — knowing roughly what to expect when an old sill comes off a house near the water, understanding how permitting and inspection work in this jurisdiction, and having a realistic sense of scheduling around our wet-season weather windows. That familiarity translates into fewer change orders and a more accurate quote from the start.
Caring for Your New Windows in This Climate
Even the best-installed window benefits from a little regular attention in a marine climate:
- Rinse salt residue and grime off frames and glass a few times a year, especially after storms
- Keep gutters and downspouts clear so overflow doesn't run down onto window trim
- Trim back vegetation that shades window walls and keeps them damp
- Check and refresh exterior caulk lines every couple of years, since sealant is the first thing to wear out
- Address any moss or algae on nearby siding and trim promptly rather than letting it spread onto window surfaces
None of this is difficult, but skipping it is how a well-installed window ends up needing early attention anyway.
