Ferndale Siding Custom Windows for Kendall Homes
Kendall sits in the rural stretch of Whatcom County out toward Mount Baker, a mix of older farmhouses, cabins, and newer builds spread out on acreage with a lot of tree cover and river-valley moisture. It's a different environment than a subdivision in town, and it asks more of a window. Between long wet winters, humidity that lingers under the trees, and the kind of driving rain that comes sideways off a storm front, a window that's slightly out of spec or poorly installed will show it within a few seasons — fogged glass, soft sills, drafts you can feel standing next to the frame. This page covers what we actually look at when we replace or install custom windows for homes in the Kendall area, and why the details matter more here than they do somewhere drier.
What Kendall Homes Are Up Against
Whatcom County's marine-influenced climate means salt-tinged air moves inland further than people expect, and even away from the water it combines with near-constant moisture to accelerate wear on anything exterior-facing. Add in Kendall's tree cover and proximity to the Nooksack River drainage, and you get extra humidity sitting against the house longer than it would in an open, sunny lot. A few things follow from that:
- Wood window sills and frames that aren't properly sealed or clad will take on moisture and start to rot from the inside, often before it's visible from outside.
- Moss and algae find a foothold on horizontal trim and sills that stay damp, which traps even more moisture against the wood or composite underneath.
- Temperature swings between cold, clear foothill nights and mild, wet days drive condensation — both on the glass and, if a seal has failed, between the panes.
- Driving rain during winter storms tests flashing and sealant details that a fair-weather installation can get away with skipping.
None of this means Kendall needs exotic materials. It means the ordinary details — flashing, sealant choice, frame material, drainage — have to be done right the first time, because the climate doesn't give a bad install much runway before it fails.
Signs Your Windows Are Due for Replacement
Homeowners usually come to us after noticing one or two of these, not because they went looking for a window project. Worth checking your own windows against this list, especially on the north and west-facing walls that catch the most weather:
- Fogging or a visible haze between the panes of a double-pane window — that's a failed seal, and it can't be fixed without replacing the unit
- A noticeable draft near the frame, even with the window latched shut
- Windows that stick, won't stay open, or take real effort to latch
- Soft, spongy, or discolored wood at the sill or lower corners of the frame
- Visible gaps between the frame and the siding or trim around it
- Moss or dark staining building up on sills or horizontal trim faster than it used to
- A heating bill that's crept up without an obvious explanation
- Single-pane glass in a home that's otherwise been updated — the weakest link in the envelope
One or two of these might just mean a caulk touch-up. Several at once, especially rot or seal failure, usually means the window itself is done.
Choosing the Right Window for a Whatcom County Property
Frame material is the biggest decision, and it should be driven by how much moisture exposure the window will see and how much upkeep you're willing to do. Here's how the common options stack up for a property like the ones we see around Kendall:
| Frame Material | Moisture Resistance | Maintenance | Relative Cost | Best Fit |
|---|---|---|---|---|
| Vinyl | Very good — won't rot, doesn't need painting | Low — occasional cleaning | $ | Most homes; best value for rain and humidity exposure |
| Fiberglass | Excellent — very stable, minimal expansion/contraction | Low | $$$ | Homes wanting a wood look with less upkeep, or extreme temperature swings |
| Wood-clad | Good on the exterior clad side; interior wood needs care | Moderate to high | $$$ | Older or historic-style homes where interior wood trim matters |
| Aluminum | Fair — durable but conducts cold and can condense | Low | $$ | Limited use; not our first recommendation for this climate |
We steer most Kendall customers toward vinyl or fiberglass for anything facing the weather, simply because they don't give moisture anywhere to work. Wood-clad has its place on homes where the interior look is a priority, but it's a product that needs an honest conversation about upkeep before you commit to it — we'll walk you through that trade-off rather than talk you out of a look you want.
What a Correct Installation Actually Involves
Assessment Before Anything Is Ordered
We measure every opening by hand rather than assuming it matches a standard size — a lot of older homes in the Kendall area have openings that have shifted slightly over the decades, or were never quite standard to begin with. This is also when we check the condition of the framing and sill, since that determines whether it's a straightforward swap or a repair job first.
Removal and Framing Repair
Old windows come out carefully so we don't tear up siding or trim that's staying in place. If we find rot or soft wood in the sill or jambs — common on older homes that have taken on years of rain — that gets cut out and replaced before a new window goes in. Setting a new window into a compromised opening just hides the problem for a season or two.
Flashing and Sealing
This is the step that decides whether a window survives a Whatcom County winter or leaks by the second one. Flashing tape and water-resistive barrier have to be integrated correctly with the existing siding, lapped the right direction so water sheds outward, with sealant compatible with both the window frame and the siding material. Skipping or rushing this is the single most common cause of window leaks we get called out to fix on other contractors' work.
Finish Work
Interior and exterior trim gets reset or replaced, insulation gaps around the frame get filled (not overfilled, which can bow a frame), and everything gets a final check for square, level, and smooth operation before we call it done.
Our Process, Start to Finish
- Free estimate. We come look at your windows in person, measure what needs measuring, and talk through what you're trying to solve — energy loss, a specific failing window, a full-home upgrade.
- Product selection. We walk through frame material, glass options, and grille or style choices based on your home and budget, not a one-size pitch.
- Scheduling. Custom windows are ordered to your exact openings, so there's a lead time between order and install — we'll give you a realistic window for that.
- Installation day. Removal, any needed framing repair, flashing, setting the new window, and finish work, typically completed in a day for most single-window jobs.
- Walkthrough. We check operation on every window with you before we consider the job finished, and go over care and warranty coverage.
Permits and Rural Property Considerations
Kendall is unincorporated, so window work there falls under Whatcom County's permitting rules rather than a city building department — that matters for anything that changes the size of an opening, since a straight swap into an existing opening is usually treated differently than an enlarged or new opening. It also matters for egress requirements in bedrooms, which we check on any replacement in a sleeping room regardless of what was there before. On older or custom-built homes, which are common out that way, openings are also more likely to be non-standard sizes, which is exactly why we measure every job by hand rather than ordering off a standard size chart.
Why a Crew That Already Works in Kendall Matters
A lot of window problems we get called to fix started as a rushed job by a crew from outside the area that didn't account for how this climate actually behaves — flashing that worked fine somewhere drier, sealant that wasn't matched to the siding, framing repairs skipped to save a day. We work in Ferndale and the surrounding Whatcom County communities regularly, which means we're not guessing at how driving rain and long wet stretches treat a window over time — we've seen it, and we build the install to hold up to it. It also means if something needs a warranty check a year or two down the road, we're a short drive away, not a company that's moved on to the next region.
