Siding Contractor in Watsonville, CA
Siding, windows, and doors — the exterior envelope that keeps everything we frame dry and sound.
Framing is the skeleton of a house. Siding, windows, and doors are the skin — and in a coastal fog belt like Watsonville, that skin has to actually work, not just look finished. A lot of the exterior problems we see on older Pajaro Valley homes trace back to one bad flashing detail at a window or a siding seam that let moisture behind the wall for years before anyone noticed.
This category covers the three exterior services we handle: siding installation and replacement, window installation, and door installation. All three get built with the same logic we use for structural framing — get the water management right first, then make it look good.
Whether it's new siding on an addition so it matches the original house, or swapping out old single-pane windows that fog and draft, we treat the exterior envelope as part of the structure, not a cosmetic afterthought.

Framers first
We understand what's behind the siding and around the window rough opening, because we're often the ones who framed it.
Flashing done right
Every window and siding seam gets flashed to shed water, not just look sealed.
Matches the existing house
On additions, we work to make new exterior finishes read as one house, not two.
