Windows & Doors Before & After in San Francisco, CA

A spec sheet can tell you the U-value of a window, but it won’t tell you what your living room will feel like at 7 p.m. in July when the fog rolls through the Sunset. That’s why we document our work. Below are real project scenarios from San Francisco homes, written the way we’d walk you through them on site: what was there, what we did, and what changed. The photos get dropped into the frames as each job wraps.

Recent Transformations

Single-Pane to Dual-Pane Replacement in the Richmond District

BeforeAfter

The house still had its original 1962 single-pane windows, and the homeowners told us they could hear the 38 Geary bus rattle the glass every twenty minutes. We pulled the old sashes and installed dual-pane low-E windows (a thin coating that reflects heat while letting light through) from our manufacturer portfolio. The result: the bus still comes every twenty minutes, but now they only know because they see it, not because the windows shake.

Fog-Rotted Frame Rebuild in the Outer Sunset

BeforeAfter

Years of damp marine air had turned the bottom corners of two front-facing window frames soft enough to push a screwdriver through. We removed the rotted wood, installed new pressure-treated frames, flashed the openings properly, and set new windows from the CGI line. The fog hasn’t stopped, but the frames now shed water the way they’re supposed to. The homeowner painted the trim herself three weeks later and told us the caulk lines were the straightest she’d ever seen.

Patio Door Swap in Noe Valley

BeforeAfter

The old aluminum sliding door had a track so worn that the door needed two hands and a hip check to open. We replaced it with a modern sliding patio door from the Mr-Glass line, set on a new, self-cleaning track. The homeowner, a woman in her seventies, now opens it with one finger. That’s the whole point of a patio door: you shouldn’t have to fight it to get to your own backyard.

Passive House Window Package on Telegraph Hill

This client approached us with a specific goal: cut heat loss without changing the look of a 1920s building that the neighbors know well. We worked with the ES Windows line, which builds high-performance frames that read as traditional from the street. Drafts are gone. The interior temperature holds steady now. And the facade still looks like 1926, which the client, the neighbors, and frankly we all appreciate.

Leaky Bay Window Remediation in the Marina

Water was tracking down the interior wall below a three-panel bay window every time a storm blew in off the Bay. We removed the window assembly, found the flashing had never been installed correctly, rebuilt the seat with proper pitch, and reinstalled new windows with correct flashing and sealing. The wall has been dry through two full winters. The Garrison Code applies here: we don’t patch over someone else’s mistake. We take it apart and fix it right.

Front Door and Sidelight Replacement in Bernal Heights

The original front door had warped enough that a half-inch gap of daylight showed along the top edge. That gap was also where the heat was leaving. We installed a Therma-Tru entry door along with new sidelight windows on either side. The entryway is now tight, quiet, and properly sealed. When the afternoon wind hits Bernal Hill, the door doesn’t move. That’s the standard.

Want Results Like These?

Every project starts the same way: you tell us what’s wrong or what you want, we walk the space, and we hand you a written price before any work starts. That price includes the full install and is covered by our 365-Day Done Right Promise. If it fails within the year, we return at no charge. Call (831) 273-7126 to schedule your estimate. A live person answers.
