Why San Leandro Homeowners Choose TruePane Windows & Doors
San Leandro calls are different. The homes are older, the salt air is real, and the scope of work behind a “drafty window” often surprises people. We measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers in writing before we leave. That’s The Keystone Standard, and it’s not a marketing phrase. It’s the founding rule Dale Kessler keeps on the whiteboard: if the pane is not true, the job is not done. Homeowners in Washington Manor and Broadmoor have called us after out-of-area installers quoted a simple retrofit, showed up, and found rotted subframes they didn’t expect. We expect it, because we’ve seen it in San Leandro hundreds of times. Our Done Right Promise is in writing: if it’s not done right, we make it right, with no paperwork fights.
Windows & Doors Services We Offer in San Leandro
Window Installation
New-construction and full-frame window installation for San Leandro homes, including the mid-century ranches that dominate this city. We work with manufacturer lines like Andersen, Pella, Marvin, and Milgard, and we’ll walk you through the differences side by side on paper.
Learn more about our Window Installation in San Leandro.
Door Installation
Entry doors, patio doors, and exterior doors installed square and true, with hardware that won’t bind in July. If your current door sticks when the humidity spikes, that’s a frame issue, not a door issue. We fix the opening before we set the slab.

Window Replacement
Replacing original aluminum sliders and jalousie windows from the 1940s through 1960s is our bread and butter in San Leandro. We check the rough opening for rot before installing, not after. No surprise line items on the bill.

Impact Windows & Doors
Impact-rated windows and doors built for windborne debris protection. San Leandro homes don’t face hurricane-force storms, but impact glazing also reduces noise from I-880 and adds a layer of security that standard dual-pane glass doesn’t.
Energy-Efficient Windows
Dual-pane, low-E glass tuned for the East Bay’s marine layer and fall Diablo winds. If your east-facing windows bake in afternoon sun in the Broadmoor district, a low-E coating makes a measurable difference in the same week it’s installed.
Sliding & Patio Doors
Sliding door tracks in San Leandro get gummed up with salt and oxidation. We replace track systems, rollers, and full door units, and we set the frame so the door glides on day one and year ten.
Glass Railing Systems
Frameless and semi-frameless glass railing for decks, balconies, and staircases. Structural glass is a specialty few contractors do well; our crews are glaziers first, which is why the glass sits plumb and the hardware doesn’t rattle in wind.
Custom Windows & Doors
Non-standard openings, historic-sympathetic replacements near Estudillo Estates, and fully custom units made to order. San Leandro’s pre-war Craftsman homes need windows that match the trim and proportion, and we handle those carefully.
Neighborhoods We Serve in San Leandro
San Leandro is a city of distinct mid-century neighborhoods, and we work all of them. Typical response time for a quote in the 94577 ZIP code is one to two business days, and we schedule installation around your timeline, not ours.

Why San Leandro’s Climate & Housing Affect Windows & Doors
San Leandro sits at the receiving end of marine layer intrusion off the Bay, and the western third of the city, especially around the Marina District, gets persistent salt-laden fog that oxidizes aluminum frames faster than anywhere inland. Original 1950s sliders in Washington Manor and Broadmoor often have corroded weep holes that have quietly directed moisture into the rough opening for decades. By the time a homeowner calls about a drafty window, there’s frequently hidden subframe rot that requires a full buck-out and framing repair before the new unit can be set. That’s the scope-creep pattern that catches out-of-area installers quoting a simple retrofit. We quote the real job, which is why our pricing includes opening inspection before the unit is ordered. Seasonal Diablo winds in fall also thermally shock dual-pane seals already weakened by year-round moisture cycling, which is why fogged glass is a common San Leandro complaint.
Pricing for Windows & Doors in San Leandro
Window replacement in San Leandro typically runs $700 to $1,400 per opening for mid-range dual-pane vinyl or fiberglass units, installed. Entry door replacement generally falls between $1,200 and $3,500 depending on the door slab, hardware, and whether the rough opening needs reframing. Impact windows add 20 to 35 percent over standard dual-pane. Custom units and historic-sympathetic work near Estudillo Estates run higher because the openings are often non-standard and the trim details are exacting. We give written, line-item quotes before work starts, and the price on the quote is the price on the bill. There are no surprise line items and no change orders without your signature. Call (888) 635-0804 for an exact quote, and ask about the permanent 5% discount for seniors and veterans.

What San Leandro Customers Say
"Whole-house window replacement at 71 years old is not something you want to do twice. Dale walked the house himself for the quote. Crew was the same three men all four days, and the foreman knew every window by room."
- Pat and Ray L."Eleven windows replaced in two days. The crew chief, Marcus, showed me the level on every single frame before they caulked it. My wife noticed the street noise was gone before I did."
- Ronald P."A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G.
