Old Town's Older Homes Need a Different Approach to Windows
Old Town Anacortes is one of the oldest built-up areas on Fidalgo Island, and it looks it — in a good way. A lot of the homes here date back to the early-to-mid 1900s, with original wood-frame construction, tall double-hung windows, and the kind of character you don't get in a new subdivision. But that character comes with a catch: most of these homes were built long before anyone was thinking about high-performance glazing, weather barriers, or the specific punishment that Skagit County's marine climate puts on a window over 60 or 80 years.
When we're called out to Old Town for a window replacement, we're rarely dealing with a simple swap. We're dealing with old jambs that have shifted slightly with the house, trim that may be worth saving, and openings that were never flashed the way building science says they should be today. Doing this right means respecting the age of the house while bringing the actual window assembly up to a standard that will hold up against what this location throws at it.

What Salt Air, Driving Rain, and Moss Season Actually Do to a Window
Salt Air and Metal Components
Anacortes sits close enough to the water that salt-laden air is a constant, low-grade factor in how exterior materials age. On windows, this shows up first in the metal parts — hinges, balance mechanisms, screen frames, and any exposed fasteners. Aluminum-clad and steel hardware corrode faster here than they would 30 miles inland. Once hardware starts to seize or pit, windows get harder to open and close properly, and a window that doesn't seat and lock correctly isn't sealing correctly either.
Driving Rain and Wind-Driven Water
Storms coming off the Salish Sea don't just drop rain straight down — wind pushes it sideways, right into the vertical face of a house. Old Town's older siding and window trim weren't always detailed with the kind of flashing and drainage planes we'd use today, so wind-driven rain finds its way behind trim boards and into the rough opening around a window. Over enough winters, that moisture rots sill framing and sheathing whether or not you can see it from inside the house.
Moss and Sustained Dampness
Skagit County's long moss season isn't just a roof problem. Moss and algae growth on north-facing walls and horizontal trim surfaces keeps wood surfaces damp for extended stretches, which accelerates rot right at window sills and the bottom corners of frames — exactly where water already tends to collect. A window that looks fine from the street can still have a soft, saturated sill hiding behind a coat of paint.
Signs an Old Town Home's Windows Are Due for Replacement
Not every old window needs to go. Some just need better weatherstripping or a repaint. Here's what we actually look for before recommending full replacement:
- Wood that's soft, spongy, or crumbles when pressed at the sill or lower frame corners
- Persistent condensation or fogging between panes on any newer double-pane units, which means the seal has failed
- Windows that are difficult to open, won't stay up, or don't latch tightly
- Visible daylight or a noticeable draft around the sash when the window is closed
- Paint that keeps bubbling or peeling on the interior or exterior sill, often a sign of trapped moisture
- A musty smell near the window or staining on interior drywall or trim below it
- Noticeably higher heating bills in a house where the windows are original single-pane glass
Choosing a Window That Fits an Older Fidalgo Island Home
Old Town homeowners usually care about two things that can pull in different directions: keeping the look of the house intact, and getting a window that actually performs against this climate. The good news is you don't have to choose one or the other — but the frame material you pick matters more here than it would in a drier, more sheltered part of the state.
| Frame Material | How It Handles Salt Air & Rain | Maintenance | Best Fit |
|---|---|---|---|
| Vinyl | Won't corrode or rot; performs consistently in coastal air | Low — no painting, occasional cleaning | Budget-conscious replacements where matching original wood trim profiles isn't a priority |
| Fiberglass | Very stable in temperature swings and moisture; holds paint well if color-matching trim | Low to moderate | Homes where long-term durability matters more than upfront cost |
| Wood-clad (exterior-clad wood interior) | Good performance if cladding and flashing are done correctly; exposed wood trim still needs upkeep | Moderate — exterior clad low maintenance, interior wood as usual | Owners wanting to preserve a traditional wood-window look inside and out |
| Aluminum | Prone to corrosion and thermal transfer in this climate; condensation-prone | Higher | We generally steer homeowners away from bare aluminum for this reason |
We're not going to tell you a certain brand or material is "junk" — every option above has a legitimate use case. Our job is to walk through what you actually want out of the window (appearance, upkeep, budget, energy performance) and match that against what holds up on a house exposed to Rosario Strait weather.
Keeping the Character Intact
If your home has the tall, narrow double-hung proportions common in Old Town, we can usually match that sightline in a modern window — same visual grid pattern, same general sash proportions — without the maintenance burden or drafts of the original glass. Where trim is original and still solid, we build the replacement to work with it rather than ripping out everything and starting from bare studs.
What a Correct Installation Involves
The window itself is only part of the job. Most of the failures we see in older coastal homes trace back to how the opening was sealed, not the window product itself.
Removal and Inspection
Every old sash and frame gets pulled with the rough opening inspected for rot, soft framing, or prior water damage. If we find compromised wood, it gets addressed before anything new goes in — installing a new window into a wet or rotten opening just guarantees the same problem resurfaces in a few years.
Flashing and Drainage
Proper window flashing directs water that gets behind the siding back out, rather than letting it pool at the sill. This includes sill pan flashing, correctly lapped side and head flashing, and integration with whatever water-resistive barrier is behind the siding. This step is invisible once the job is done — but it's the single biggest factor in whether a window replacement lasts 20 years or leaks again in five.
Sealing and Insulation
Gaps around the new frame get properly insulated and air-sealed, not just caulked over on the surface. A window can be top-quality and still perform poorly if the gap around it is sealed sloppily.
Finish Work
Trim, casing, and any painting or staining are matched to the house so the replacement doesn't look like a patch job — particularly important on homes where the exterior character is part of the value.
Our Process for an Old Town Window Replacement
- On-site assessment — we look at each window individually, since older homes rarely have uniform conditions across every opening
- Honest scope — we tell you which windows need full replacement, which could get by with repair, and why
- Written estimate — clear pricing with the material options laid out, no pressure to upsize the job
- Scheduled installation — timed around weather where possible, since open wall cavities and rain don't mix well here
- Flashing and sealing done to current standards, regardless of the age of the surrounding construction
- Final walk-through — every window operates correctly, seals correctly, and looks right before we call it done
Why Local Experience in Old Town Anacortes Matters
A crew that mostly works new construction in drier parts of the state isn't necessarily thinking about salt air corrosion or wind-driven rain patterns off the water. Working regularly in Anacortes and across Skagit County means we've already seen how these older homes behave over decades — where the rot tends to start, which sills fail first, how much moss buildup is normal versus a drainage problem. That experience shows up in the details: the flashing sequence, the caulking choices, the hardware we recommend for salt exposure. It's the difference between a window that's replaced once and one that has to be revisited in a few years.
Energy and Comfort Payoff
Beyond stopping water and rot, replacing old single-pane or failed-seal windows makes a real difference in comfort during Anacortes' damp, windy winters. Modern double-pane (or triple-pane, for north- and west-facing exposures that take the brunt of storms) units cut down on drafts, reduce condensation on the interior glass, and ease the load on your heating system. In an older home, this is often one of the more noticeable upgrades a homeowner can make, since original windows are usually the single biggest source of heat loss in the building envelope.
