AfterWindow Company in San Lorenzo, CA
Window and door work in San Lorenzo comes down to one reality: this is a mid-century housing market, and most of the windows still in place are original to homes built in the 1940s and 1950s. Single-pane aluminum frames, worn weatherstripping, and patio sliders that stick when the marine layer rolls in off the Bay. We replace, install, and service windows and doors here full time. The job is matching modern glass and frames to older openings without ripping out stucco or trim that’s better left alone. If you’re pricing a project in San Lorenzo, call (817) 686-2228 and we’ll put the number on paper before any work starts.
Why San Lorenzo Homes Are Different
San Lorenzo was built as one of the Bay Area’s first planned communities, and the housing stock reflects it. Most of the single-family homes off Hesperian Boulevard, Paseo Grande, and Bockman Road date to the 1944 – 1958 build-out, which means standard window rough openings, but also six decades of settling, stucco patches, and homeowner modifications. We regularly see openings that have shifted a quarter inch or more since the original sash went in. That changes how we measure, order, and flash every unit.
The other factor is the wind. San Lorenzo sits in the Hayward wind corridor, and the prevailing afternoon breeze off the Bay puts real pressure on west-facing windows and patio doors. Frames that flex in the wind leak air, and air leaks are what drive heating and cooling costs up. Homes closer to the BART corridor and the San Lorenzo Creek drainage also deal with more morning humidity, which accelerates wood rot around sills and door thresholds. None of this is exotic. It just means the install details matter more than the brand sticker on the glass. Our crews are trained to shim, square, and seal to the opening that actually exists, not the one on the original blueprint.
Our Main San Lorenzo Services
Window replacement and installation are the two calls we get most from San Lorenzo homeowners, and patio door work runs a close third. Each service has its own page with pricing, process, and local specifics.
Window Replacement in San Lorenzo
Replacement in San Lorenzo usually means pulling an original single-pane sash out of a wood or aluminum frame and setting a new double-pane insert into the existing opening. It’s the right move when the frames are still square and the homeowner wants better glass without tearing into stucco. We carry PGT and ViewLux lines that fit the common 1950s rough openings here, and we measure every unit before we order a thing. Full details are on the Window Replacement in San Lorenzo page.
Window Installation in San Lorenzo
New-construction or full-frame installation is for openings where the old frame is too far gone to save: rotted sills, heaved corners, or water damage from years of leaking flashing. In San Lorenzo that often means the original wood frame on the east side of the house, where winter rains hit first. We remove the old frame down to the rough opening, install a new one, and flash it properly before the trim goes back on. See the Window Installation in San Lorenzo page for what’s involved.
Patio Door Installation in San Lorenzo
The original aluminum patio sliders in San Lorenzo ranchettes and post-war plans are usually the first thing to fail. Rollers wear out, tracks bend, and the door ends up needing two hands and a hip check to move. We install modern sliding and hinged patio doors from CWS and CGI, sized to the existing rough opening, with new thresholds sealed against the damp ground-level conditions common along the Hayward corridor. More on the Patio Door Installation in San Lorenzo page.

What pushes the number up in San Lorenzo is usually stucco repair around a full-frame install, rotten sheathing hidden behind the old flashing, or an opening that needs re-squaring before the new unit can sit right. All of that goes in the written quote. You’ll know the price before we order a single window.

FAQs About Window Company in San Lorenzo
We schedule San Lorenzo calls by the week, not the month. Most replacement and installation jobs are on the calendar within five to seven business days of the written estimate. Hardware repairs and urgent seal failures usually get a visit sooner. Call (817) 686-2228 and we’ll tell you the next open slot.
Some San Lorenzo Village HOAs have architectural review rules for visible exterior changes, particularly street-facing windows and front doors. If your street falls under one, we’ll note it during the estimate and work the approval into the schedule so the installation doesn’t stall mid-project. It’s an extra step, not a deal-breaker.
Every window and door we install in San Lorenzo is covered in writing for 365 days. If the installation fails or the workmanship isn’t right, we come back and fix it at no charge. That guarantee is on the paperwork before we start. The product warranties from PGT, CGI, CWS, and ViewLux run separately and are registered at completion.
We can give you a rough range over the phone using the window count, sizes, and material you’re after. But the number we stand behind comes from a site visit. Measuring the actual opening, checking the framing, and looking at the exterior finish is what keeps the written price from changing when the old window comes out.
