Siding Replacement Across Snohomish County

Every Era of Northwest Siding, All in One County

Drive from Everett's old mill-town blocks out Highway 2 toward Monroe and you pass a complete museum of Pacific Northwest cladding. Cedar bevel siding on the prewar homes near the waterfront. T1-11 plywood on the ranches and split-levels that filled the county in the 1960s and 70s. The pressed-composite lap sidings of the 80s and 90s on subdivisions from Mill Creek to Lake Stevens — product lines whose region-wide failures ended in lawsuits and taught every contractor here what wood fiber does when it cannot dry. Each era fails in its own way, and Snohomish County's climate, with the convergence zone piling extra rainfall onto its central band, accelerates all of them.

We spend our days replacing all three. The cedar is often worth saving where it is old-growth and sound. The T1-11 is usually delaminating at the bottom edge from decades of splash-back. The 90s composite is swelling at every butt joint and nail head, and once that starts, no paint job on earth is more than a delay.

What Replacement Should Include in This Climate

Modern fiber cement is our workhorse recommendation for most county homes — it holds paint through freeze-and-soak cycles, resists the woodpeckers that riddle composite claddings, and comes in lap widths that suit everything from a 1925 Everett foursquare to a 1995 two-story in Marysville. But the product matters less than the wall behind it. Every Alpine Exteriors siding job includes lapped and taped weather barrier, flashing at window heads and trim transitions, kick-out flashings at roof-wall intersections, and a rainscreen gap so the wall can dry between the county's two hundred wet days. That assembly, not the plank, is what a free on-site estimate from us is really pricing.

We work across the whole map — Everett, Lynnwood, Marysville, Snohomish, Monroe, and the unincorporated stretches between — and handle each jurisdiction's permitting ourselves.

The Difference in the Details

• Tear-off and inspection, always — rot and sheathing damage fixed in the open, with photos.
• Rainscreen assembly standard — a drying gap engineered for convergence-zone rainfall.
• Trim and transition craftsmanship — belly bands, corners, and casings that finish the house, not just cover it.
• Factory-primed or pre-finished options — color warranties measured in decades.

Alpine Exteriors has put 25 years into exterior work in western Washington and carries the lessons of more than 2,000 completed projects onto every wall we open. The 25-year workmanship warranty we attach to each job is the plainest statement of intent we can make: we expect to drive past this house for decades, and we intend to be glad we did. If your siding is swelling, checking, shedding paint, or simply carrying its age badly, have us look now — in this county, a cladding problem is always a moisture problem in progress, and the walls keep score.
