Windows Built for Old Town's Particular Climate
Old Town Anacortes sits close enough to the water that its houses take a different kind of weather beating than homes even a few miles inland. Salt-laden air off the marine waters works on metal fasteners and hardware year-round. Driving rain, pushed sideways by wind off the water, tests every seal and sill on the west and south faces of a house. And the shade from mature trees and close-set older lots means a long moss season that keeps siding, trim, and window sills damp for weeks at a stretch. None of that is unique to any one house in the neighborhood — it's just what Skagit County waterfront living does to a building envelope over the decades.
Custom windows matter here for a simple reason: a lot of Old Town's housing stock predates modern standard window sizing. Off-the-shelf replacement units often don't fit the openings without reframing, shimming, or trim modifications that compromise both the look and the weather-tightness of the house. Getting this right takes measuring, material choices, and installation detail suited to this specific neighborhood — not a generic replacement job.

What "Custom" Actually Means Here
Non-Standard Openings
Many homes in this part of Anacortes were built before window manufacturers standardized on today's common sizes. Rough openings can run narrower, taller, or oddly proportioned compared to what ships in a catalog. A custom window is built to the exact opening — or the opening is corrected properly rather than papered over with wide trim boards that hide a bad fit and give water somewhere to collect.
Matching the House's Character
Old Town has a real mix of older bungalows, craftsman-influenced homes, and later infill construction. Grille patterns, sash proportions, and trim profiles all affect whether a new window reads as part of the house or as an obvious retrofit. Custom sizing and configuration options let us keep the visual proportions the house was built with, even when the glass and hardware inside are entirely modern.
The Climate Factors That Should Drive Your Choice
Salt Air and Hardware
Salt air accelerates corrosion on anything ferrous — screws, hinges, cranks, and lock hardware. It's slow, so a lot of homeowners don't notice until a window starts sticking or a lock won't turn smoothly anymore. We pay attention to the hardware finish and fastener specification on every install here, not just the frame material, because hardware failure is usually what makes an otherwise good window feel old before its time.
Driving Rain and Water Management
Wind-driven rain doesn't just hit a window — it gets pushed up and under trim, sills, and poorly lapped flashing. The exposure a window faces (which direction, how sheltered by roof overhang or neighboring structures) should change how much attention goes into flashing detail and sealant choice. A window that's fine on a sheltered north wall can leak within a couple of seasons on an exposed west-facing wall if it's installed the same way.
Moss, Shade, and Moisture Cycling
Shaded, tree-covered lots stay damp longer after a storm, and that moisture cycling — wet, humid, wet again — is hard on caulk lines, wood sills, and any gaps in the weather barrier. Moss and algae growth on sills and lower sashes isn't just cosmetic; it holds moisture against the surface. Material choice and detailing at the sill are where this shows up first.
Comparing Window Materials for This Environment
| Material | Salt Air / Moisture Behavior | Maintenance Level | Fit for Old Town Homes |
|---|---|---|---|
| Vinyl | Won't corrode; performs well in salt air and rain exposure | Low — occasional cleaning | Good value option; limited custom color/profile range on some older-style openings |
| Fiberglass | Very stable in temperature and moisture swings; strong long-term performance near water | Low | Handles custom sizing well; higher upfront cost |
| Wood-Clad | Exterior cladding protects the wood, but any breach in the cladding lets moisture into the core | Moderate to higher — cladding and seals need periodic inspection | Best for matching historic sightlines and interior wood trim |
| Aluminum | Prone to corrosion and condensation issues in a marine climate unless thermally broken | Moderate | We generally steer homeowners away from bare aluminum frames in this specific environment |
There's no single "right" material for every house — it depends on the exposure of that particular wall, the look you're trying to keep, and your budget. We'll walk through the actual trade-offs for your house rather than push one option across the board.
Our Installation Process
The window itself is only part of a good installation. Most window failures we get called out to look at trace back to installation detail, not the window unit failing on its own. Our process for Old Town Anacortes homes includes:
- On-site measurement of each opening individually — older homes rarely have identical openings from window to window
- Inspection of the existing framing and sheathing for hidden rot or moisture damage before the new unit goes in
- Proper sill pan flashing so any water that does get past the window has somewhere to drain, not soak into the framing
- Correct lapping of house wrap and flashing tape, shingle-style, so water always sheds outward and downward
- Marine-grade or high-performance sealants rated for the temperature and moisture swings this coastal climate produces
- Shimming and squaring the unit so sashes operate smoothly and locks engage fully — misaligned units are what let wind-driven rain in
- Interior and exterior trim work finished to match the surrounding house, not just caulked and left
- Full cleanup and haul-away of old units and packaging
We also check the condition of the rough opening before we ever set a new window. If there's rot or water damage from years of exposure, replacing the window without addressing that framing just seals a problem behind new glass.
Common Mistakes We See on Older Window Jobs in This Area
A few patterns show up repeatedly when we're called in to fix or replace work done elsewhere in the neighborhood:
- Standard-size replacement units forced into non-standard openings with excess shimming and caulk instead of proper resizing
- Flashing skipped or reversed (taped in the wrong order), which traps water against the sheathing instead of shedding it
- Bare aluminum or low-grade hardware used without accounting for salt-air corrosion
- Caulk used as the only water barrier, with no mechanical flashing behind it — caulk is a backup, not a strategy
None of these are dramatic mistakes on day one. They show up two, five, or ten winters later as soft trim, fogged glass, or windows that won't latch — right around the time driving rain season finds the gap.
Maintenance That Actually Matters Here
Good installation reduces maintenance, but it doesn't eliminate it. In a salt-air, moss-prone environment like Old Town Anacortes, a short annual routine goes a long way:
- Rinse sills and lower sashes to clear salt residue and organic buildup before it holds moisture
- Check and lubricate hardware annually — cranks, hinges, and locks are the first parts salt air affects
- Inspect exterior caulk lines for cracking or separation, especially on west- and south-facing exposures
- Trim back vegetation that keeps a window shaded and damp for extended periods
Why a Crew That Already Works Old Town Anacortes Matters
Window installation quality is mostly about judgment calls — how much flashing overlap a given wall needs, whether an opening needs reframing or just careful shimming, which material handles a shaded, moss-prone north wall better than a sun-exposed west wall. Those judgment calls get better with repetition in the same conditions. A crew that regularly works this specific stretch of Skagit County has already seen how these houses age, where water tends to find its way in, and what actually holds up through a few winters of driving rain and salt air — versus what looks fine on installation day and fails quietly a couple of years later.
We're not guessing at what this climate does to a window installation. It's the same weather, the same housing stock, and largely the same problems we see across this neighborhood, job after job.
Get a Straight Answer for Your House
Every house in Old Town Anacortes has its own mix of opening sizes, exposure, and existing condition, and that's exactly what determines the right window approach — not a one-size-fits-all recommendation.
