Window Company in San Lorenzo, CA
Window and door work in San Lorenzo follows the rhythm of the housing stock here: 1940s and 1960s ranch tract homes, stucco exteriors, and a lot of original aluminum sliders that were never meant to last sixty years. Cool, damp winters and fog intrusion put condensation on single-pane glass, and west-facing afternoon sun bakes older frames until they stick or warp. We quote every job with a written price before any work starts, and we back our work with a 365-Day Done Right Promise. Call (252) 675-6980 and we’ll walk you through what your San Lorenzo home needs.
Why San Lorenzo Homes Are Different
San Lorenzo’s post-WWII tract homes pack single-pane aluminum windows into shallow stucco walls, and because the unincorporated community enforces Alameda County’s strict energy code through its own building department, every window replacement requires a Title 24 prescriptive or performance compliance package. That’s a step homeowners in neighboring Hayward or Castro Valley don’t always face in the same way, and it catches people off guard when a “simple” window swap turns into a paperwork project. We handle the Title 24 documentation on every replacement, so the permit path is our job, not yours.
The housing stock here is dominated by 1940s through 1960s single-story ranches, many with original wood double-hung frames or aluminum sliders. Some homes have been re-sided with vinyl, others have had windows updated piecemeal over the decades. What that means in practice: rough opening depths and flashing details vary door to door, even on the same block. A window that fits flush on one house might need a custom jamb extension two houses down. We measure and order to the opening, not to an assumption.
Marine-influenced air brings cool, damp winters and fog that lingers well into summer mornings. Dual-pane vinyl or fiberglass frames with low-E glass (a thin coating that blocks heat while letting light through) make a measurable difference in condensation and energy loss here. Windows facing west and south also need solar heat gain control, which is a standard part of how we spec replacements for San Lorenzo homes.
Our Main San Lorenzo Services
Most San Lorenzo homeowners call us for one of three things: tired or leaking windows replaced, failing hardware or fogged glass repaired, and front doors that no longer close, lock, or seal the way they should. Each service has its own dedicated San Lorenzo page with pricing, timelines, and details.
Window Replacement in San Lorenzo
Replacing windows in a 1950s San Lorenzo ranch usually means pulling original aluminum sliders out of stucco openings and fitting modern dual-pane units into rough openings that may not be perfectly square. We handle the Alameda County Title 24 compliance package with every replacement, so you never have to guess whether the job will pass inspection. We carry lines including PGT, CGI, and ViewLux, and we match the frame material and glass package to the exposure and the opening, rather than pushing one product. Full details, including pricing, are on the Window Replacement in San Lorenzo page.

Window Repair in San Lorenzo
Fogged dual-pane glass, worn balances, broken locks, and cranks that have stripped out are common in San Lorenzo’s older tract homes, especially where original hardware has been painted over for decades. We repair what can be repaired and tell you straight when replacement makes more sense. Every repair carries a written guarantee; if it fails, the second visit is free. See Window Repair in San Lorenzo for what we fix and what it costs.

Front Door Replacement in San Lorenzo
Many San Lorenzo ranch homes still have their original wood entry doors, and sixty years of damp winters and afternoon sun leaves them swollen, warped, or out of square. A new Therma-Tru or ViewLux door, properly flashed and sealed for a stucco opening, changes both curb appeal and how the house holds heat. We handle the full install, including threshold and trim, and we quote a written price before any work begins. The Front Door Replacement in San Lorenzo page covers options and pricing.
