Fast, Reliable Custom Windows & Doors Across San Leandro
Custom window and door work in San Leandro is not a one-size-fits-all job, and the difference shows up in the materials. For a typical Custom Shape Windows replacement in the Washington Manor neighborhood, homeowners should expect to pay between $1,800 and $4,200 per opening, depending on frame material and whether the original rough opening needs structural repair. We answer the phone at (888) 635-0804 around the clock, and we have worked enough tract homes between Farnsworth Avenue and the Marina District to know what hides behind a 60-year-old aluminum slider before we quote it. That local knowledge matters because San Leandro’s marine air punishes the wrong spec faster than nearly any other city in the East Bay.
Why TruePane Windows & Doors Is San Leandro’s Preferred Custom Windows & Doors Company
We have been at this since 2008 through a second-generation glazier’s craft tradition, and Dale Kessler founded this company in 2008 on a rule that still sits on the whiteboard: if the pane is not true, the job is not done. San Leandro homeowners tend to notice when a crew actually measures twice, quotes manufacturer lines side by side on paper, and registers both warranty layers in writing before the truck leaves the driveway. That is The Keystone Standard, and every job we run in 94577 gets it without having to ask.
Our Custom Windows & Doors team includes background-checked, uniformed technicians who have replaced original jalousie windows in Broadmoor, rebuilt rotted subframes in Washington Manor, and set oversized glass panels in Marina District homes where the salt fog off San Leandro Bay is hardest on hardware. Live people answer our phones 24 hours a day, seven days a week. When a San Leandro homeowner calls about a slider that has seized shut three days before a family visit, they speak to a person who can dispatch a local crew, not a call center.
Our Custom Windows & Doors Services in San Leandro
We install and replace windows and doors for residential homeowners across San Leandro, with particular experience in the custom work that mid-century and pre-war homes demand. Here is what that looks like on the ground.
Custom Shape Windows
San Leandro’s postwar ranches and stucco bungalows often have odd-shaped openings: eyebrow arches over entry doors, trapezoid panels beside rooflines, half-round vents in gable ends. A Custom Shape Windows job in a 1950s tract home typically runs $1,800 to $4,200 per unit, including templating and a marine-grade frame. We measure every opening twice and order the exact radius, because a window that is off by a quarter inch in San Leandro’s persistent humidity will bind within two seasons.

Architectural Grilles & SDLs
When San Leandro homeowners want the divided-light look of an original Craftsman window without rebuilding the wood sash, architectural grilles and simulated divided lites offer the same sightlines at a lower cost than full wood replacement. In Estudillo Estates, where pre-war Colonial Revival homes sit on Bancroft Avenue and the surrounding streets, we regularly match original muntin profiles in Andersen, Marvin, and Ply Gem lines. A typical SDL upgrade adds $120 to $260 per window over the base unit price, and the grille pattern is set inside the insulated glazing so it never collects fog or dust.

Oversized Glass Panels
Bay-facing homes in San Leandro’s Marina District and along the western edge of the city often have picture windows and patio sliders that span eight or more feet. Oversized glass panels for those openings require tempered or laminated glazing, heavier frames, and a crew that knows how to set a 400-pound unit in a rough opening that has been wetted by salt fog for decades. We quote these jobs at $3,200 to $7,800 depending on panel size and frame spec, and we never shortcut the flashing because that is exactly where the marine air attacks first.

Commercial Storefront Glazing & Curtain Wall Systems
San Leandro has a working commercial core along East 14th Street and Washington Avenue, and many of those storefronts are original aluminum from the 1960s and 1970s. We handle commercial storefront glazing and curtain wall systems for property owners who need storefront glass replaced without disrupting business hours. Curtain wall work in San Leandro typically runs $85 to $150 per square foot installed, with the higher end reserved for systems that need marine-grade framing and thermal breaks to handle bay humidity.

Trusted Brands We Service in San Leandro
We are an authorized installer for more than a dozen manufacturer lines, and on San Leandro jobs we commonly quote, PGT, and Ply Gem because those lines offer marine-grade frame options that hold up to salt air. We also carry local parts for CGI and CWS impact-rated products, which matter on the city’s bay-facing western edge where wind-driven rain hits hardest. When a San Leandro homeowner needs a replacement sash or a hardware kit for an existing window, we can usually source it faster than an out-of-area installer who has to order from a regional warehouse.
Common Custom Windows & Doors Problems We See in San Leandro Homes
San Leandro’s specific combination of 60-to-80-year-old housing stock and marine-layer humidity creates failure patterns we do not see ten miles inland. Here are the four we encounter most often:
- Corroded aluminum weep holes in original 1950s sliders. Washington Manor and Broadmoor tract homes were built with aluminum sliding windows whose weep holes were designed to drain condensation. In San Leandro’s salt fog, those tiny channels crust over with white oxide within a few decades, trapping moisture in the rough opening until the subframe rots behind the wallboard.
- Thermal shock failures in west-facing dual-pane glass. Fall Diablo wind events bring sudden hot, dry gusts that hit west-facing windows already weakened by year-round moisture cycling. Argon-filled seals crack, fogging appears between the panes, and the only real fix is a new insulated glass unit with a robust edge seal rated for marine air.
- Warped and seized sliding door tracks on bay-facing homes. Salt-laden humidity swells wood tracks and oxidizes aluminum rollers on original patio sliders. By the time a homeowner in the Marina District calls, the door often will not open at all without lifting the entire panel off its track.
- Hollow-core exterior doors that have swollen past the jamb. Bay-facing homes take the worst of it: unpainted bottom rails absorb salt-laden humidity, the door swells, the deadbolt no longer lines up, and the only solution is replacing the door with a solid-core or fiberglass unit with a fully sealed bottom rail.
Pricing for Custom Windows & Doors in San Leandro, CA
What you pay for custom windows and doors in San Leandro depends less on the window style than on what the marine air has done to the opening behind it. Here is what we quote, on average, for the most common jobs in the city:
- Custom shape window replacement: $1,800-$4,200 per opening, including marine-grade frame and templating.
- Standard single window replacement (vinyl or fiberglass): $850-$1,700 per unit, installed.
- Oversized glass panel or picture window: $3,200-$7,800, including tempered or laminated glass and heavy-duty framing.
- Architectural grilles and SDLs added to an existing quote: $120-$260 per window.
- Full buck-out and subframe repair (common in Washington Manor and Broadmoor): $600-$1,800 per opening, added to the window cost.
The gap between an inland-spec window and a marine-spec window for the same opening is usually $400 to $800. That is real money, and it is the cheapest money you will spend on that opening. An inland-spec aluminum frame will show visible pitting within five years a mile from the Bay, and the subframe rot will be worse than what we just tore out. We quote both options on paper, side by side, so you can see exactly what you are buying. Call (888) 635-0804 for a free estimate.

FAQs - Custom Windows & Doors in San Leandro
A marine-grade aluminum frame with an AAMA 2604 or 2605 finish lasts roughly 2.5 to 3 times longer than a standard mill-finish aluminum frame in San Leandro’s salt-fog zone. A standard frame on a Bay-facing home will show pitting and corrosion within 5 to 7 years; a marine-grade frame from the same manufacturer typically holds up for 18 to 22 years. Call (888) 635-0804 for an exact quote, and we will show you both options side by side on paper.
Because the original aluminum slider’s weep holes have been sending fog condensation into the rough opening for decades before you ever notice a draft. By the time we pull the old unit, the subframe is often rotted enough that a new window cannot be set square. A full buck-out and reframe adds $600 to $1,800 per opening, and we will always explain what we found before we proceed. Estimates are free, so call (888) 635-0804 if you suspect hidden damage.
Choose a dual-pane unit with at least a 90% argon fill and a low-E coating on surface two, plus a warm-edge spacer system. In Broadmoor, west-facing windows take the brunt of fall Diablo winds, and cheap edge seals crack under the temperature swings. We specify a marine-rated edge seal on every west-facing window we quote in the 94577, because a failed seal means fogged glass and a replacement unit within a few seasons. For a precise quote, call (888) 635-0804.
Yes. We use Architectural Grilles & SDLs from manufacturers like Andersen and Marvin to replicate the original muntin profiles, including era-correct widths, inside the insulated glazing. This gives you the look of true divided lites without the rot, air infiltration, and maintenance that plague original wood sash in San Leandro’s humid climate. The upgrade typically adds $120-$260 per window. Call (888) 635-0804 and we will bring grille samples to your home.
A marine-grade casement uses a frame and hardware rated for coastal salt exposure: stainless steel hinges, a sealed compression gasket system, and frame finish that resists pitting for 18 to 22 years. A standard casement uses zinc-plated hardware and a mill finish that will show corrosion inside a decade near the Bay. The marine spec costs $400 to $800 more per window, and it is the only spec we recommend for homes in the Marina District or any home within a mile of the water. We will quote both lines side by side. Call (888) 635-0804 for a free estimate.
