Window Replacement Across Whatcom County, WA

Whatcom County asks a lot of a window. The same county contains salt-air waterfront at Point Roberts and Sandy Point, dairy-country farmhouses around Lynden and Everson, mid-century neighborhoods in Bellingham and Ferndale, and cabins in the Mount Baker foothills that see real snow load and hard frosts. Alpine Exteriors has replaced windows in every one of those settings over 25 years working in northwest Washington, and the right window is not the same in all of them.

The County's Windows Problem, in Two Parts

Most Whatcom County homes built from the 1960s through the 1980s got single-pane aluminum sliders, and those are the windows we replace most. Aluminum conducts cold straight through the frame, so on damp winter mornings the interior frame drops below the dew point and streams condensation. Years of that produces the stained sills, peeling paint, and musty window corners that county homeowners know too well. The second problem is wind. Winter southwesterlies off the bays and the notorious northeast outflow that pours through the Fraser gap toward Sumas and Lynden both drive rain and cold air through worn seals, and drafty windows in a heating-dominated climate show up directly on the utility bill.

Matching Windows to Where You Live

On a free on-site estimate, we look at your home's exposure before we recommend anything.

• Vinyl and fiberglass frames with warm-edge Low-E glass that end frame condensation in damp inland neighborhoods
• High wind and water ratings for exposed sites near the water and in the northeaster belt along the border
• Tempered and larger fixed units for view walls facing the bay, the valley, or the Cascades
• Egress-compliant bedroom windows when we are updating older farmhouses and cabins to current code

Farmhouses Deserve Careful Hands

The county's older farm homes around Lynden, Everson, and the Nooksack Valley often have out-of-plumb openings, deep wood casings, and layers of siding from past remodels. We take the time to square, flash, and insulate each opening properly, because a beautifully made window installed poorly performs like a cheap one.

One Contractor, County-Wide

From Blaine to Acme, our crews cover all of Whatcom County, and more than 2,000 completed projects in the region mean there is a good chance we have already worked on your road. We install full-frame or insert replacements depending on the condition of your existing frames, and we are honest about which your house needs, since insert windows over rotten frames just hide a problem.

Every window we install is protected by our 25-year workmanship warranty, covering the sealing and flashing that keep our famous sideways rain outside where it belongs. If your glass fogs between panes, your sills stay wet all winter, or certain rooms never warm up, have us out. The estimate is free, and the difference on the first cold morning is immediate.
