Sedro-Woolley Siding Replacement | Alpine

Siding a Timber Town's Homes for the Next Fifty Years

Sedro-Woolley was built by lumber — the mills, the loggers, and the streets of sturdy millworker homes they left behind. A century later, the town at the gateway to the North Cascades still has one of Skagit County's most character-rich housing stocks: early-1900s workers' cottages and farmhouses near the old downtown, mid-century ranches in the postwar blocks, and rural homes strung along Highway 20 as it heads up-valley toward Concrete. What most of them share is original or aging wood siding that has absorbed a hundred years of Skagit Valley weather and is asking for relief.

The valley's climate is quietly hard on walls. Winter fog settles over the flats and keeps everything damp for days; the river valley funnels wind and rain; and the shoulder seasons deliver freeze-thaw cycles that work every crack in old paint a little wider. Alpine Exteriors has re-sided homes in these conditions for 25 years, and we've learned that in Sedro-Woolley the job is half carpentry and half detective work — you never fully know what a hundred-year-old wall is hiding until the siding comes off.

What We Find, and What We Do About It

That's why our process is built around the tear-off. Rather than nailing new material over old problems, we strip to the sheathing and correct what we find:

• Sheathing repairs where decades of slow leaks around windows and hose bibs have softened the boards beneath
• A modern weather-resistive barrier — something most of these homes have never had a proper version of
• Flashing at every window head, door, and trim transition, the small metalwork that decides whether a wall stays dry
• New siding fastened to manufacturer spec, whether that's fiber cement lap, LP SmartSide, or cedar for owners keeping the traditional look

Fiber cement is the most popular choice in town for good reason: it ignores the valley's dampness, holds paint through fog seasons that would blister wood, and delivers the crisp lap-siding shadow lines these older homes were designed around. On farmhouses and heritage homes, we can match historic reveals and rebuild the wide corner boards and window casings that give them their proportions.

Farm Properties and Outbuildings Too

Plenty of our Sedro-Woolley work happens outside city limits — on acreage where the house, the shop, and the barn all face the same weather. We side and trim outbuildings to match the main home, and having completed 2,000+ projects across the county, we're comfortable scaling from a compact cottage to a full farmstead.

The Alpine Standard

Every installation carries our 25-year workmanship warranty, and every project starts the same way: a free on-site estimate where we walk the walls with you, probe the suspect spots, and put honest numbers on paper. If some elevations can wait a few years, we'll say so — a straight answer costs nothing and earns the next call.
