Anacortes Siding Old Town Anacortes is one of the older residential pockets in the city, and the homes here carry the kind of character you don't find in newer subdivisions — original wood siding, older framing, and windows that in many cases have never been touched since the house was built. That character is worth protecting, but it comes with a real cost: older window units in this neighborhood are usually the weakest point in the building envelope, and they're working against a coastal Skagit County climate that doesn't cut anyone a break.
Why Windows Take a Beating in Old Town Anacortes
Anacortes sits close to the water, and that proximity changes what a window has to deal with day to day. Salt-laden air corrodes exposed hardware, pits aluminum components, and breaks down cheap sealants faster than it would a few miles inland. Add in driving rain that comes in sideways off the water during winter storms, and any gap in flashing or a worn-out sash gets tested constantly rather than occasionally. Then there's the moss and mildew season, which around here can stretch across most of the year — anywhere moisture sits against wood trim or a sill without a way to dry out, you're building a rot problem in slow motion.
Older homes in this part of town often still have their original single-pane wood windows, or a mix of those and a dated aluminum-frame replacement from decades back. Both types share the same basic problem after enough years: the seals fail, the frames shift as the house settles, and what used to be a tight opening becomes a path for air and water. Homeowners usually notice it as a draft, a foggy pane, or a sill that's gone soft — but by the time it's obvious, there's a good chance moisture has already reached the framing underneath.
What a Correct Installation Actually Involves
Swapping in a new window is the easy part to picture. The part that actually determines whether the job lasts is what happens at the opening before the new unit ever goes in. In a marine climate like Anacortes, we treat every window opening as a water management problem first and a fit-and-finish problem second.
Inspecting and Prepping the Opening
Before anything gets installed, we pull the old unit and look at what's actually there — the condition of the framing, whether there's existing rot or staining, and whether the opening is still square. Older homes in Old Town Anacortes settle over the decades, and it's common to find openings that are slightly out of level or out of square, which means a modern window can't just be dropped in without some careful shimming and adjustment to get it sealing correctly.
Flashing and Water Management
This is the step that separates a window that lasts twenty-plus years from one that starts leaking in five. That means a proper sill pan to direct any water that gets past the exterior seal back outside rather than into the wall cavity, correctly lapped flashing tape integrated with the existing weather-resistant barrier, and sealant used deliberately — not as a substitute for good flashing, but as a backup to it.
Insulating the Gap
The space between the new window frame and the rough opening needs to be filled with a material that stays flexible and doesn't compress or shrink over time, which cuts down on drafts and helps prevent condensation from forming inside the wall. Spray foam that's rigid and over-expanded can actually bow a frame out of square, so this step takes a light hand, not just a full can of foam.
Choosing the Right Window for a Coastal Old Home
Material choice matters more here than it would in a drier inland climate, because whatever goes in has to hold up to salt air and sustained moisture exposure for decades. There's no single right answer for every home, but here's how the common options compare for a house like the ones in Old Town Anacortes:
| Frame Material | Performance in Salt Air / Moisture | Maintenance | Fit for Older Homes |
|---|---|---|---|
| Vinyl | Can become brittle with long-term UV and salt exposure; budget-friendly | Low, but hardware and seals wear over time | Works, though profiles can look modern against original trim |
| Fiberglass | Very stable in moisture and temperature swings; resists corrosion well | Low | Good option; holds paint if you want to match historic trim colors |
| Wood (new, factory-finished) | Authentic look for an older home, but needs a good exterior cladding or finish to handle rain exposure | Higher — finish needs upkeep | Best match for original character, if maintenance is acceptable |
| Aluminum-clad wood | Exterior aluminum sheds weather well; interior wood keeps the traditional look | Moderate | Common middle-ground choice for older coastal homes |
We'll talk through these trade-offs honestly rather than pushing whatever's easiest to install. A home with a lot of original trim detail might be worth the extra upkeep of a wood or clad option; a rental or a home where low maintenance matters more than matching original profiles might do better with fiberglass or a quality vinyl unit.
Single-Pane vs. Modern Insulated Glass
Almost every original window left in Old Town Anacortes is single-pane, which means it's doing next to nothing for energy efficiency and often has a good deal of condensation and drafting to show for it. Moving to a modern insulated unit — double-pane at minimum, with the option of upgraded gas fills or low-E coatings — makes a noticeable difference in comfort and in reducing the moisture that collects on cold glass during our wetter months. It won't change the character of the house if the frame profile and grille pattern are chosen to match what's already there, which is something we pay attention to on older homes specifically.

- Repair of any rot or damaged framing found during removal — not papered over, actually fixed
- Proper sill pan and flashing installation integrated with the existing wall assembly
- Setting, shimming, and squaring the new window, even when the original opening isn't perfectly square
- Insulating the gap and sealing the exterior with materials suited to a marine climate
- Interior and exterior trim work finished to match the home's existing look
- Final walkthrough so you understand what was done and what to watch for going forward
Signs an Old Town Anacortes Home Needs Window Attention
- Visible fogging or moisture trapped between panes on a supposedly sealed unit
- Drafts you can feel near the frame, especially during winter storms off the water
- Soft, discolored, or crumbling wood at the sill or bottom corners of the frame
- Windows that are difficult to open, close, or lock due to swelling or warped frames
- Paint that's peeling or bubbling on the interior trim near the window, which often points to trapped moisture
- Visible gaps between the frame and siding, or caulking that's cracked and pulling away
- Moss or dark staining building up on the sill or exterior trim
Any one of these on its own might not be urgent. Several of them together, especially on a home that's had the same windows for a few decades, usually means the building envelope is due for an honest look.
Permits and Working Within an Older Home's Character
Window replacement in the City of Anacortes typically requires a permit, and the specifics can depend on the scope of the work and the age of the structure. We handle that process as part of the job rather than leaving it for the homeowner to sort out. Because Old Town Anacortes has a concentration of older homes, we also try to be thoughtful about matching grille patterns, frame profiles, and trim details to what's already there, so a window upgrade improves performance without making the house look out of place next to its neighbors.
Why It Matters to Hire a Crew That Knows This Neighborhood
Older homes don't behave like new construction. Openings aren't always square, framing lumber dimensions can differ from what's standard today, and the original trim details often need to be worked around rather than replaced wholesale. A crew that's spent time on homes in Old Town Anacortes and similar older neighborhoods knows what to expect before they even open up the wall — that experience shows up in fewer surprises, fewer change orders, and a finished job that actually accounts for how this climate and this housing stock behave together. It also means showing up with the right expectations about weather windows, since installing windows during a driving-rain stretch off the water isn't something you want to rush.
Keeping New Windows Performing Long-Term
A correctly installed window in a coastal Skagit County climate should need very little from you, but a little seasonal attention goes a long way. Wipe down tracks and weep holes so they don't clog with debris or moss buildup, check exterior caulking once a year for cracking, and keep an eye on trim paint or finish so small chips don't turn into moisture entry points. None of this is a big job, but skipping it is how a well-installed window ends up with an avoidable problem a decade in.
