Window Company in Los Altos, CA
Window and door work in Los Altos runs into three local realities on nearly every job: older ranch homes with original single-pane glass, strict tree-protection and sightline rules, and summer heat that pushes under-insulated frames hard. We spec and install windows, doors, and patio sliders that hold up to those conditions, and every project starts with a written price before any work begins. That is how Meridian Windows & Doors operates across Los Altos. Call (817) 686-2228 for a free estimate.
Why Los Altos Homes Are Different
Much of Los Altos was built between the 1950s and 1970s, and a lot of that original aluminum-framed glass is still in place. Those frames conduct heat, the seals dry out, and in neighborhoods like North Los Altos and the Country Club area, homeowners face a second layer: mature oaks and redwoods that shade windows in summer but also drive moisture and leaf litter against sills all winter. The result is a mix of fogged double-panes, stuck sliders, and frames that have quietly warped over decades.
Los Altos also enforces its own planning review for exterior changes on many properties, particularly anything visible from the street. If you are replacing windows on a home with protected heritage trees or within certain setback zones, the city may want to see the window schedule before sign-off. We work through those permit details with you and the city, and the quoted price accounts for the paperwork up front. A meridian is a fixed line you measure everything against, and that is what the name means and how we run every install in Los Altos.
Our Main Los Altos Services
Most Los Altos homeowners reach out for one of two reasons: existing windows have failed and need replacing, or a new build, addition, or remodel needs windows and doors installed from scratch. Below are the three services we handle in Los Altos, each with its own page.
Window Replacement in Los Altos
Replacement work in Los Altos usually means pulling aluminum or wood frames that have lost their seal, then setting new units into the existing openings. Older homes here often have non-standard rough openings, so we measure every opening individually and order to those dimensions rather than forcing a stock size. Low-E glass, which is a thin coating that reflects heat while letting light through, matters more on the west-facing walls that catch the afternoon sun off the foothills. Read the full breakdown on our Window Replacement in Los Altos page.

Window Installation in Los Altos
New-construction and addition work changes the sequence: the rough openings are framed, we set and flash the windows, and the exterior finishes go on after. Los Altos hillside lots add a wrinkle because many additions sit on elevated foundations with steeper drainage planes, so sill flashing and weep detailing have to be right the first time. We pull the permit, coordinate with the builder’s schedule, and leave the openings clean and square. Details are on the Window Installation in Los Altos page.

Patio Door Installation in Los Altos
Patio doors in Los Altos run from standard sliding glass doors on 1960s ranchers to multi-panel and French-style units on newer builds. The common failure points here are rollers that grind after years of dust and pollen from the oaks, and tracks that fill with fine clay grit from the adobe soil on the flatlands. We install new sliders, French doors, and multi-slide systems, level the track properly, and seal the threshold against winter rain. See Patio Door Installation in Los Altos for the full scope.

Prices in Los Altos push higher when the home sits on a hillside with limited staging access, when the city requires extra plan review for street-facing elevations, or when original openings are out of square and need reframing. Whatever the number is, it goes on paper before any work starts, and it does not move at the door.
