AfterWindow Company in San Leandro, CA
Window and door replacement in San Leandro typically runs $800 – $2,400 per opening depending on the product line, with most projects scheduled within one to two weeks of the estimate. We work across the city’s post-war housing stock, from Washington Manor’s original tract homes to bayfront properties near the Marina, where marine-layer humidity and decades of micro-seismic movement create conditions you won’t find in newer East Bay suburbs. Every job starts with a written, itemized price before we touch anything, backed by our 365-Day Done Right Promise. Call (562) 478-8017 to schedule your free estimate.
Why San Leandro Homes Are Different
San Leandro sits directly in the seismic shadow of the Hayward Fault, and that geological reality shapes nearly every window and door job we do here. The post-WWII wood-frame tract homes that dominate Washington Manor, Bay-O-Vista, and surrounding neighborhoods were built between 1945 and 1965 on fill and alluvial soils that have settled and shifted through decades of micro-quakes. We routinely find door frames racked out of square and window openings distorted enough that a replacement unit won’t seat without first shimming, blocking, and reframing the rough opening.
The marine climate adds its own layer of complexity. Bayfront neighborhoods west of I-880, especially near the San Leandro Marina, see persistent salt air that corrodes aluminum window frames and steel door hardware faster than anything we encounter inland. Seasonal Diablo winds push hot, dry air against west- and north-facing elevations, drying out weatherstripping and stressing sealed units. In Estudillo Estates, original Craftsman-era wood-sash double-hungs often arrive with glazing compound turned to dust and sashes painted shut by decades of maintenance shortcuts.
One detail that surprises crews new to San Leandro: sliding glass doors installed in the 1950s and 1960s frequently have roller tracks so distorted by foundation movement that the frame must be shimmed and reblocked before a standard replacement will operate smoothly. It’s a step we build into every estimate for these homes, not a change order we discover mid-job.
Our Main San Leandro Services
Most San Leandro homeowners call us for one of three projects. Each has its own dedicated page with detailed pricing, product recommendations, and local job specifics.
Window Replacement in San Leandro
We replace original single-pane aluminum sliders in Washington Manor, fogged dual-pane units in Bay-O-Vista ranches, and painted-shut wood sashes in Estudillo Estates. Every replacement starts with a frame-squareness check, since Hayward Fault micro-movement often leaves openings out of plumb. We carry PGT and CGI impact-rated options for homeowners upgrading to modern energy standards, plus ViewLux vinyl lines that stand up to salt air without the maintenance burden of aluminum.

Window Installation in San Leandro
New window installation in San Leandro means working with openings that may have settled, shifted, or been modified by previous owners. We measure twice, square once, and never assume a new-construction rough opening. Our crews carry CWS and ECO Window Systems new-construction and retrofit flanges to match your siding, whether it’s original T1-11, mid-century stucco, or a later remodel. Shoe covers and drop cloths go down before any tool comes out. Window Installation in San Leandro
Door Installation in San Leandro
Door installation here often means reframing before the new unit goes in. Steel entry doors from the 1950s and 1960s have rusted at the threshold, and the frames behind them are rarely square after sixty years of soil movement. We stock Therma-Tru fiberglass entry systems and multi-point hardware that won’t corrode in marine air, and we shim every frame to operate true regardless of what the surrounding structure has done over the decades.

FAQs About Window Company in San Leandro
Most San Leandro estimates are scheduled within three to five business days, with installation crews available one to two weeks after you approve the written quote. Call (562) 478-8017 to check current availability.
Permit requirements depend on the scope. Like-for-like replacements in the same opening typically don’t trigger permitting, but enlarging openings, structural reframing, or changes to egress requirements do. We pull all necessary permits as part of the job and schedule inspections so you don’t have to coordinate with the city.
Many San Leandro HOAs, especially in Washington Manor and Bay-O-Vista, maintain design guidelines for visible elevations. We review your CC&Rs during the estimate and specify products that meet both the HOA’s aesthetic requirements and California’s energy code. Written documentation for HOA submission is included at no extra charge.

What San Leandro Customers Say
"Replaced six windows. The crew laid runners through the house and vacuumed each room as they finished. With a crawling baby, that no mess thing meant a lot. Windows are gorgeous."
- Rosalind Kemp"Lovely windows and a tidy install. One window came in a couple weeks late from the factory, so that opening finished after the others. They kept me posted and the rest was spotless."
- Mia Donnelly"Quiet, considerate install of several windows. They cleaned the glass and the sills and vacuumed every room. You'd never know a crew had been through. House is quieter and brighter."
- Brent Sakamoto
