- Elevating Exteriors – From Concept to Completion
Windows in this corner of Washington take a specific kind of beating. Between the driving winter rain off the Sound, wind that funnels across the open Skagit flats and through the Strait of Juan de Fuca, and the salt air that rolls onto Camano Island and Anacortes, window seals, frames and hardware wear out faster here than in drier inland climates. Most homeowners do not think about their windows until something is obviously broken, but by then the damage is often more than glass deep. Below is a practical look at the warning signs worth acting on, what causes them locally, and how to tell whether you are looking at a same-season replacement or something you can reasonably plan around.
Most windows installed in the last few decades in this area are double-pane insulated glass units, with a sealed air or gas-filled gap between two panes and a desiccant strip in the spacer bar to keep that gap dry. When the seal fails, outside moisture works its way in, and it fogs the inside of the sealed unit rather than the surface you can wipe clean. This shows up faster on windows that face prevailing weather, particularly west- and south-facing units that catch the brunt of winter storms rolling in off the water. Once a seal has failed, cleaning does nothing, and the fog tends to come and go with humidity and temperature until it eventually becomes permanent.
Run a hand around the perimeter of a window sash on a windy day and you should not feel air moving. If you do, the weatherstripping has compressed or dried out, or the frame itself has warped enough to break the seal against the sash. This is a common complaint in homes exposed to the wind that comes off the Skagit flats and picks up speed with nothing to slow it down between Mount Vernon, Burlington and La Conner. Older wood and aluminum frames flex slightly under sustained wind pressure, and over years that flexing opens gaps that were not there when the window was new.
Wood swells with moisture and shrinks as it dries out, and in a climate with as much winter rain as this one, that cycle repeats every year. Eventually the frame or sash warps just enough that the window binds in the track, won't stay propped open on its own, or the lock no longer lines up with the strike. This is mechanical wear, not a cosmetic issue, and it usually means moisture has already gotten past the exterior paint or cladding and into the wood itself.
Press a thumb into the wood at the bottom corners of a window sill or frame. If it gives slightly, feels spongy, or the paint is bubbling and peeling in that spot, moisture has been sitting there long enough to start breaking down the wood fibers. Bottom corners and sills fail first because that is where water collects and drains slowest, especially on north- or shade-facing walls where the wood never fully dries out between storms. Left alone, soft wood spreads and eventually compromises the window's structural fit in the rough opening, not just its appearance.
This is different from fog trapped inside a sealed unit. This is moisture forming on the interior-facing surface of the glass itself during cold snaps. It is common with older single-pane or early double-pane windows that simply cannot keep the interior glass surface above the dew point in a cold, damp house. It is worsened by daily life, showers, cooking, houseplants, drying laundry, and by any window whose insulating performance has fallen behind current standards. Recurring condensation is worth attention beyond fogged glass, because sustained moisture on window sills and sashes is what eventually leads to the wood rot described above.
Homes on Camano Island, in Anacortes, and elsewhere within reach of salt air see faster corrosion on aluminum window frames, hinges, and cranks than homes further inland. Look for white powdery pitting on aluminum, rust bleeding from steel fasteners, or hardware that has gone stiff and hard to operate. Vinyl frames don't corrode the same way, but salt-laden air combined with UV exposure can leave a chalky residue on the surface over time. Corroded hardware is often the first component to fail on an otherwise sound window, and it is worth checking separately from the glass and frame itself.
Windows are rarely the only culprit behind a higher bill, but they are an easy one to rule in or out. Hold a hand near the glass on a cold morning; if the interior surface feels noticeably colder than the wall around it, that window is doing very little insulating. Homes with a mix of original and replaced windows often show this clearly: rooms with older single-pane or poorly sealed units are harder to keep comfortable and cost more to heat than rooms with newer, code-compliant glass.
A gradual increase in how much wind, rain, or road noise you hear indoors is a slower, easier-to-miss sign of the same seal and glazing failures described above. As gas fill leaks out of a failed insulated glass unit, or weatherstripping compresses, the window's ability to dampen sound drops along with its ability to hold heat. If a room that used to feel quiet during a windstorm off the Strait now rattles or lets in more sound, that is worth investigating even if the glass still looks clear.
Not every sign on this list means a window needs replacing this month. Some are cosmetic and can be scheduled around a normal budget; others point to ongoing water intrusion that gets more expensive the longer it sits.
The honest caveat here: a fogged or drafty window is an inconvenience and a slow energy drain, not an emergency, and there is no need to rush a decision out of anxiety. Rotting wood around a window, on the other hand, tends to spread into the surrounding wall framing and sheathing if it sits through another wet winter, and that turns a window job into a larger repair.
Start with a walk around the exterior on a dry day, and a hand-check of every window from the inside on a windy or rainy one. Most of the signs above are things you can find yourself without any special tools. Take note of which windows are affected, which direction they face, and whether the problem looks cosmetic or structural. If more than a couple of windows show real signs of wear, or if you find soft wood anywhere in a frame, it is worth having someone look at the whole house rather than patching one window at a time, since exposure and age tend to affect windows on the same wall or elevation together.
Replacement windows installed in Washington today have to meet the U-factor and performance requirements in the Washington State Energy Code, which is worth asking about directly. A contractor should be able to tell you the U-factor of the units they are proposing and how that compares to what is currently in your walls. Alpine Exteriors walks homeowners through that comparison as part of every window estimate, along with a straightforward look at what is failing, what can wait, and what a realistic cost range looks like before any commitment is made.
In some cases the sealed glass unit itself can be swapped out of an existing frame if the frame is still sound, which costs less than a full window replacement. This only makes sense when the frame, sash and hardware are in good shape and the window style is still one the homeowner wants to keep. If the frame is also worn, or the window is old enough that matching glass units is difficult, full replacement usually ends up being the more practical option.
A single window can often be replaced in under an hour once the crew is on site, but a whole-house project depends heavily on the number of windows, their size, and whether any are full-frame replacements versus insert units into an existing frame. Most residential jobs in this area run from a single day for a handful of windows up to a week or more for a larger home with many openings.
It depends on the scope of the work and the jurisdiction. Straightforward like-for-like replacements are often permit-exempt, while changes to the size of an opening, structural work, or larger whole-house projects typically do require a permit and inspection tied to the Washington State Energy Code's window performance requirements. A licensed contractor should be able to tell you what applies to your specific project and city or county before work starts.
Newer windows built to current energy code standards insulate significantly better than older single-pane or early double-pane units, so most homeowners do see a real reduction in heating costs, particularly in rooms that previously felt drafty or cold near the glass. That said, windows are one part of a home's overall envelope. Insulation, air sealing elsewhere, and the furnace or heat pump all play a role too, so it is reasonable to expect a meaningful improvement rather than a specific guaranteed percentage.
If you are seeing one or more of these signs on a home in Mount Vernon, Anacortes, Burlington, Sedro-Woolley, La Conner, Stanwood, Camano Island, Bellingham, or anywhere else in Skagit, Island or Whatcom County, Alpine Exteriors can take a look and give you a clear, no-pressure read on what is actually going on: which windows can wait, which shouldn't, and what a realistic budget looks like for the work that matters. Alpine Exteriors holds Washington contractor license ALPINI751OW and handles roofing, windows, decks and gutters across this region, so a window inspection can also flag related issues, like sill damage tied to a gutter or roof problem, before they turn into separate projects.
