If you live in Los Altos, you probably know the signs already. The aluminum slider to the back patio sticks in July but rattles in January. The big picture window facing the street fogs between the panes every morning from May through October. The original single-pane glass in a 1962 ranch lets heat pour out all winter while the furnace runs double shifts. TruePane Windows & Doors handles window and door work for Los Altos homeowners every week, and our crews know exactly what they’re going to find before they pull into the driveway. Call (888) 635-0804 and a live person answers, any hour, any day.

Why Los Altos Homeowners Choose TruePane Windows & Doors
Most of the calls we take from Los Altos start the same way. A homeowner has lived in the house for twenty or thirty years. They’ve patched a fogged seal once, maybe twice. They had a contractor out who said the rough opening was fine, then the new slider bound up six months later. We get those calls because Dale Kessler founded this company on a rule he keeps on the whiteboard to this day: if the pane is not true, the job is not done. That standard carries through our Done Right Promise. If the work isn’t right, we make it right. No paperwork fights, no arguing about who shimmed what. The Keystone Standard means both manufacturer warranty layers are registered in writing, with durations stated, before the truck leaves your driveway.
We work regularly in North Los Altos and South Los Altos, from the ranch rows around Heritage Oaks Park to the wider lots off Magdalena Avenue near the country club. Los Altos homeowners tend to know their neighbors, and they ask around before hiring. Our name comes up because we show up on time, in uniform, with background-checked technicians who measure every opening twice and quote manufacturer lines side by side on paper.
Windows & Doors Services We Offer in Los Altos
Window Installation
We install picture windows, casements, double-hungs, and full wall-to-wall glass systems throughout Los Altos. Every unit gets measured twice and set true before the first fastener goes in. A window that’s installed out of plane will sag, bind, and void its warranty eventually. We set it right the first trip.
Learn more about our Window Installation in Los Altos.
Door Installation
Entry doors, French doors, and custom wood units go in square and plumb, with proper threshold support and weather sealing. Los Altos ranch homes often have settling slabs, so we account for out-of-level floors rather than masking them. The door will swing clean and latch true when we leave.

Window Replacement
Original windows on 1950s and 1960s homes in Los Altos are almost always single-pane aluminum. Replacing them with dual-pane insulated glass changes condensation, noise, and heating behavior on the same day. We remove old frames down to the rough opening, correct any framing issues, and reset everything properly.

Impact Windows & Doors
We install and replace impact-rated units including PGT and CGI lines. While Los Altos doesn’t face hurricane force winds, impact glass adds meaningful security and sound reduction, and many homeowners pair it with their renovation for the structural rigidity it provides.
Call (888) 635-0804 to discuss impact-rated options for your home.
Energy-Efficient Windows
Low-E coatings, argon-filled dual panes, and thermally broken frames deliver real reductions in summer heat gain and winter heat loss. Los Altos sits in a Title 24 compliance zone, so we quote systems that meet or exceed current California energy code. We’ll register the manufacturer’s energy and glass warranties in writing before we leave.
Call (888) 635-0804 to schedule a free estimate on energy-efficient windows.
Sliding & Patio Doors
Multi-panel sliders and folding door systems are standard renovation choices in Los Altos, not luxury afterthoughts. We install and replace them with attention to track condition and rough-opening square. If the old track has bowed from decades of morning dew, we correct the framing before the new door goes in.
Call (888) 635-0804 to talk through slider and patio door options for your home.
Glass Railing Systems
Frameless glass railings and stair balustrades are common on Los Altos remodels and additions. We fabricate and install tempered glass panels to exact measurements, with clean hardware lines and code-compliant anchoring. The work is finished to the same standard as our windows and doors.
Call (888) 635-0804 for glass railing pricing and a free estimate.
Custom Windows & Doors
For odd rough openings, architectural-grade wood-clad units, or a wall of glass that spans twenty feet, we handle full custom work. We quote manufacturer lines side by side on paper so you see exactly what you’re buying. Custom fabrication takes longer, but the finished product is built to the exact opening, not adapted to it.
Call (888) 635-0804 to discuss your custom project with our team.

Why Los Altos’s Climate & Housing Affect Windows & Doors
Los Altos is built on 1950s through 1970s single-story ranch homes, and that housing stock drives almost every window and door decision we see. Low-pitched roofs and wide eaves protect walls but leave full-width front picture windows fully exposed. Original aluminum single-pane sliders to rear patios have been taking morning dew for sixty years. That routine overnight condensation, even in the so-called dry months, accelerates seal failure on dual-pane retrofits and corrodes the anodized aluminum frames on original units. We routinely open up walls on the east side of town and find 1960s slider tracks that have bowed and pitted so badly the rough opening is no longer square. That’s a framing correction, not a simple slider swap, and it’s exactly the kind of thing a homeowner can’t see until the drywall comes down. Los Altos homes are also overwhelmingly renovated rather than torn down, due to the city’s design-review culture. That means whole-home window and door replacement is the norm, and the work has to hold up because the owner is staying put.
Because median home values in Los Altos sit comfortably above $3M, the baseline expectation on most jobs is premium. We quote PGT and CGI impact lines, ES Windows for architectural aluminum, and thermally broken wood-clad systems far more often than vinyl. Los Altos homeowners treat a twenty-foot multi-panel slider or a wall of floor-to-ceiling fiberglass picture windows as a standard renovation spec. Our job is to know those product lines cold, quote them honestly, and install them clean.

What Los Altos Customers Say
"Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A."Two entry doors. Showed up when they said, second day was a half day like they said, and the painter they recommended confirmed the frames were dead plumb. The financing was explained in actual dollars, not a brochure."
- Janet R."Impact windows on the whole house. They handled the permit, the inspection, and gave me a folder with every approval number for the insurance company. My windstorm premium dropped enough to notice."
- Bill T.
