AfterWindow Company in Sebastopol, CA
Window and door work in Sebastopol means dealing with older wood-framed homes, heavy fog cycles, and a building stock that runs from 1940s farmhouses to newer hillside builds. Most homeowners here call us after rot has set in around a sash or a patio door has started binding in its frame. We handle window replacement, window installation, and patio door installation, and we write the price down before any work starts. If you’re unsure what your project needs, call (817) 686-2228 and we’ll talk it through.
Why Sebastopol Homes Are Different
Sebastopol sits in a coastal-influenced pocket of Sonoma County where morning fog and damp winters put real stress on window frames and exterior doors. Older homes near Bodega Avenue and the downtown grid often have single-glazed sashes and uninsulated frames. The moisture cycle here means wood rot, stuck sashes, and condensation between panes show up more often than in drier inland cities. Homes on the hillsides above town also get heavier wind exposure, which loosens weatherstripping and makes patio doors rack out of square over time.
Many Sebastopol neighborhoods have homes from the 1960s and 1970s with aluminum-frame windows that were installed fast and never flashed properly. That leads to leaks inside the wall, not visible until the trim comes off. When we open a wall on a Sebastopol remodel, we routinely find sill rot that nobody saw from the outside. The local combination of fog, older framing, and hillside exposure means window and door jobs here need more than a box-store swap. They need someone who reads the house before ordering the product.
Our Main Sebastopol Services
Window replacement, window installation, and patio door installation are the three jobs Sebastopol homeowners call us about most, and each one has its own page with local pricing and detail.
Window Replacement in Sebastopol
Replacing windows in Sebastopol usually means pulling out a failed unit and installing a new one in the same opening. On older homes, we often find rotten sill plates or missing flashing behind the old frame, and that gets addressed before the new window goes in. Most replacement jobs here involve double-hung or casement windows, and the fog zone means we recommend low-E glass (a thin coating that reflects heat while letting light through). Window Replacement in Sebastopol has full local pricing by window type.
Window Installation in Sebastopol
New window installation comes up in Sebastopol when a homeowner is adding an addition, finishing a garage, or changing the opening size on a remodel. The county’s planning rules for new openings depend on the structure, and we’ll walk you through what needs a permit before any cutting starts. Window Installation in Sebastopol covers the process, timeframes, and what to expect on a new-opening job.
Patio Door Installation in Sebastopol
Patio doors in Sebastopol take a beating from westside fog and afternoon sun. Sliders bind when their track fills with grit, and older French doors leak at the threshold once the sill settles. We install new sliders, French doors, and multi-slide units, and we check the rough opening before anything is ordered. Patio Door Installation in Sebastopol has model-specific pricing and lead times.

What pushes the price up in Sebastopol is wall condition, not the window itself. Older homes with rot behind the frame, missing flashing, or out-of-square rough openings take more labor to set right. That’s why our price goes on paper before any work starts. It doesn’t move at the door.
