Glacier sits differently than the rest of Whatcom County. At roughly a thousand feet of elevation on the Mount Baker Highway, with heavy tree cover, short winter daylight, and weather that swings between soaking rain and hard freezes, a siding project here runs on a slightly different clock than one in Bellingham or Ferndale. This page walks through what actually happens, in order, when Alpine Exteriors replaces siding on a Glacier-area home — so you know what to expect before crews show up and what's reasonable to ask of any contractor working on your house.
Most single-family homes in the Glacier area take somewhere between one and three weeks from the first day of tear-off to the final walkthrough, depending on the size of the house, the siding material chosen, and how much of the wall sheathing underneath needs repair. That range is wider than you'd hear for a comparable job in town, and there's a reason: Glacier's dense fir and cedar canopy keeps siding damp longer after a rain, which means crews sometimes lose a half-day waiting for wall sheathing to dry enough to install a weather-resistive barrier correctly. Rushing that step to hit a deadline is how call-backs for trapped moisture happen two winters later.
A realistic sequence looks like this: one to two weeks of lead time for permitting and material ordering before any crew arrives, then three to ten working days of on-site labor depending on square footage, then a final week held loosely in reserve for weather delays, since Glacier can see rain, sleet, or an early snow event even in shoulder-season months when the lowlands are still dry. Homeowners who build in that buffer are rarely disappointed; homeowners who expect a five-day turnaround on a 2,400-square-foot house with rot repair are usually the ones who end up frustrated with the schedule, even when the crew is working efficiently.
| Phase | Typical duration | What's happening |
|---|---|---|
| Estimate & contract | 1–2 weeks | Site visit, moisture readings, material selection, written scope |
| Permitting & ordering | 1–4 weeks | Whatcom County permit review; siding, trim, and flashing ordered |
| Tear-off & sheathing repair | 1–4 days | Old siding removed; rot cut out; sheathing patched or replaced |
| Weather barrier & flashing | 1–2 days | House wrap, window and door flashing, seams taped |
| Siding installation | 3–8 days | New siding, trim, and accessories installed |
| Punch list & walkthrough | 1 day | Final inspection, caulking, cleanup, homeowner walkthrough |
Glacier is unincorporated, so siding permits go through Whatcom County Planning & Development Services rather than a city building department. A straightforward re-side (same footprint, no structural changes) is usually a simpler review than new construction, but if more than a small percentage of wall sheathing needs replacement, or if the scope opens up insulation cavities, the project can trigger a look at Washington State Energy Code requirements for wall insulation and vapor control. Alpine Exteriors pulls the permit and handles that review as part of the contract, but it's worth knowing it's happening in the background — it's one of the reasons the schedule includes a permitting window before tear-off ever begins.
Most Glacier properties are on private lots or small plats without a homeowners association, but if your home sits within one of the newer developments near the Mount Baker Rim area, check your covenants for exterior color or material restrictions before finalizing a product. It's a five-minute check that avoids a repaint or resubmission after the fact.
Material lead times are the other piece worth planning around. Vinyl siding in common colors is often the fastest to source, sometimes a couple of weeks. Fiber cement products like James Hardie lines run longer, often four to eight weeks depending on the profile and color, especially for factory-primed or pre-finished options. Cedar siding, still a popular choice in this part of the county for its look against the mountain backdrop, can have the longest lead time of all if a specific grade or width isn't in regional stock. None of this is unique to Glacier, but because the town itself has limited local supply and everything comes up the highway from Bellingham or Everett, it pays to lock in material selections early rather than mid-project.
Once permitting clears and materials are on hand, the physical work follows a set order, and skipping steps in that order is where problems start.
A little preparation on your end keeps the schedule moving. Clear a few feet of access around the perimeter of the house — move potted plants, patio furniture, and anything hanging on exterior walls. If you have exterior-mounted items like security cameras, string lights, or a satellite dish, let the crew know in advance so they can work around or temporarily relocate them. Vehicles should be moved out of the driveway on tear-off and delivery days, since materials often arrive on a boom truck that needs clear space to unload.
Inside the house, expect some noise and vibration during tear-off, especially near rooms that share a wall with the work area. If you have pets that are sensitive to noise or strangers in the yard, plan for that during the loudest days. And because Glacier homes often rely on well water and sometimes propane tanks or above-ground fuel lines along exterior walls, flag the exact locations of those to your contractor before work starts — it's a simple conversation that prevents an accidental strike.
Once installation wraps up, the county building inspector signs off on the permitted work where required, confirming the siding, flashing, and any structural repairs meet code. Alpine Exteriors then runs its own internal punch list before calling it done — checking caulking lines, fastener patterns, trim gaps, and touch-up paint.
Cleanup includes a magnetic sweep of the yard for stray nails and screws, removal of all old siding and packaging debris, and a final check that landscaping and hardscaping are back in their original condition. The final walkthrough is done with you, in daylight, so you can see the work up close rather than from the ground. This is the time to point out anything that doesn't look right — a caulk line, a color match at a seam, a trim detail — before the crew leaves the site.
New siding isn't maintenance-free, even in a climate this wet. Moss and algae growth on north-facing and shaded walls is common in Glacier given the tree cover, and a periodic soft wash — not a high-pressure blast, which can force water behind laps and seams — keeps growth from taking hold long-term. Gutters should be checked each fall before the rains set in, since overflow running down a wall is one of the more common causes of premature wear on any siding material. And after a hard freeze-thaw stretch, a quick visual check of caulk lines and trim joints is worth the ten minutes it takes.
Workmanship coverage from Alpine Exteriors and manufacturer warranties on the siding material itself are separate things, and it's worth understanding both before signing a contract. Manufacturer warranties typically cover material defects for a long term but often prorate over time and can have specific maintenance requirements to stay valid; workmanship warranties cover installation quality and are usually shorter. Ask for both in writing, and ask what voids each one — pressure washing technique and gutter maintenance are common exclusions worth knowing about up front.
Once tear-off starts, most single-family homes take one to three weeks of on-site work, with the wider end of that range reserved for larger homes, extensive rot repair, or stretches of persistent rain that slow drying time between stages. This is separate from the permitting and material ordering lead time that happens before the crew ever arrives.
Sometimes, and it's worth planning for the possibility rather than being surprised by it. Homes in shaded, high-moisture spots like Glacier see wood rot behind old siding more often than homes in drier, sun-exposed parts of the county, particularly on north walls and around windows with aging flashing. A written estimate should include a contingency process for how sheathing repair is priced if it's discovered mid-project, rather than leaving it as an open-ended surprise.
In most cases, yes, and it goes through Whatcom County Planning & Development Services since Glacier is unincorporated. Alpine Exteriors pulls the permit and manages the inspection process as part of the project, but the timeline for review is outside our control, which is part of why it's built into the front end of the schedule rather than assumed away.
There isn't a single right answer — it depends on your budget, maintenance tolerance, and the look you want. Fiber cement handles moisture and freeze-thaw cycling well and needs little upkeep beyond periodic washing. Cedar fits the mountain aesthetic many Glacier homeowners want but requires more regular maintenance to fend off moisture and staining. Vinyl is the most budget-friendly option and performs fine here, though it can become brittle in hard, sustained freezes. We'll walk through the tradeoffs for your specific home during the estimate rather than push one material by default.
If you're planning a siding replacement in Glacier or anywhere else in Whatcom County — Bellingham, Ferndale, Lynden, Blaine, Birch Bay, Sudden Valley, or the islands — Alpine Exteriors can walk your property, take moisture readings, and put together a written scope and timeline before any work begins.
