Siding Replacement in Kent, WA | Alpine Exteriors

Drive the residential streets of Kent's East Hill or West Hill and you will see the same siding story on house after house: 1960s, 70s, and 80s ramblers and split-levels wearing original T1-11 plywood panels or first-generation lap siding, now several decades past their intended lifespan. The bottom edges wick water off the ground splash zone, the grooves channel rain into the panel seams, and the Green River Valley's damp air — fog hanging over the valley floor well into many mornings — never gives any of it a chance to fully dry. Alpine Exteriors replaces this aging cladding with siding designed for exactly this climate.

Why T1-11 and Early Lap Siding Fail in the Valley

T1-11 was the budget workhorse of Kent's boom decades, and it served its time. But plywood siding fails from the edges inward: ground splash rots the bottom course, unflashed horizontal seams let water behind the panel, and once the outer veneer delaminates, paint cannot save it. Early composite lap sidings from the same era have their own failure modes — swelling, edge-crumbling, and fastener pull-through. If your siding is soft at the base, mushrooming at the butts, or growing dark stains that repainting cannot cover, the material is telling you it is done.

What We Replace It With

For Kent homes we install cladding chosen for wet-side durability and honest value:

• Fiber cement lap siding — rot-proof, fire-resistant, and holds factory finishes for years in valley humidity
• Fiber cement panel with battens — a clean modern update for split-levels originally clad in T1-11
• LP SmartSide engineered wood — wood warmth with treated-strand durability, a strong mid-budget choice
• Premium vinyl systems — the lowest-maintenance path for rental properties and budget-focused projects

Every re-side includes full tear-off (never siding over rot), sheathing repair where we find damage, modern weather-resistive barrier, and metal flashing at every horizontal joint, window head, and penetration — the details Kent's original builders skipped and the reason their siding is failing now. We also correct clearances at grade and rooflines so the new material never sits in the splash zone that killed the old.
