Window Company in San Bruno, CA
Window and door work in San Bruno comes down to three things: fog, wind, and homes built on hillsides. We’re Juniper Windows & Doors, the window and door specialist inside the Relay Home Co. family, and we handle replacement, installation, and door swaps across the city with one standard that never changes: a written price before a single screw turns, backed by our 365-Day Done Right Promise. Call (682) 281-2168 for a free estimate, and you’ll talk to a real person, not a voicemail.
Why San Bruno Homes Are Different
San Bruno sits on the eastern slope of the Santa Cruz Mountains, which means two things for windows and doors. First, the marine layer rolls in from the Pacific most mornings and settles over the hillsides west of El Camino Real. That persistent damp air finds its way into old wood frames around Huntington Park, Crestmoor, and Rollingwood, and once a frame starts to soften, the window loses its seal and the fogging begins. Second, wind comes off the gap between San Bruno Mountain and Sweeney Ridge with enough force to rattle a poorly seated window or send a hollow-core door slamming against its frame.
Much of the housing stock dates from the 1950s through the 1970s, when aluminum single-pane windows and thin steel doors were the standard. Those products were never designed for coastal air, and forty years of exposure leaves tracks that stick, locks that seize, and glass that does almost nothing for the heating bill. Homes on steeper lots in Portola Highlands and along San Bruno Avenue also deal with drainage against foundation walls, which makes proper flashing and sill sealing the difference between a door that lasts and one that rots from the bottom up.
Our Main San Bruno Services
Most San Bruno homeowners call us for one of three reasons: windows that no longer hold a seal, windows going into a new opening or addition, or a door that’s warped, drafty, or simply looks done. Each service has its own page with the full details, local pricing, and what to expect.
Window Replacement in San Bruno
Replacing windows in San Bruno usually means pulling out old aluminum or wood units and setting in new frames built for the marine climate. The most common jobs we see are fogged double-panes on homes near Junipero Serra Park and single-pane originals throughout the Crestmoor tract. We carry PGT and ViewLux lines with low U-factors, which matters when the fog sits on the glass until noon. Every job starts with a written quote. Window Replacement in San Bruno

Window Installation in San Bruno
New construction and additions call for window installation rather than replacement, and San Bruno’s hillside lots make rough opening prep and flashing work the priority. Whether it’s a bedroom addition near San Bruno Avenue or a rebuild off Sneath Lane, the install needs to account for wind-driven rain and the ground shifting on the slope. We install the full range of sizes and styles, from fixed picture windows to casements, with the same upfront pricing on every opening. Window Installation in San Bruno

Door Replacement in San Bruno
Front doors in San Bruno take a beating from the morning fog and the afternoon sun off the bay. We replace warped wood entry doors, rusted steel units, and sliding patio doors, often with Therma-Tru fiberglass models that won’t swell or stick when the humidity spikes. The most common call we get is a door that’s dropped on its hinges and drags across the threshold, usually on homes near the downtown corridor off San Mateo Avenue. Door Replacement in San Bruno

What pushes a San Bruno quote higher is the hillside factor: steeper lots mean more leveling work around the rough openings, and older homes on post-and-pier foundations sometimes need extra structural blocking before new windows drop in. Whatever the number is, it’s in writing before we start, and it doesn’t change unless you change the scope.
Neighborhoods We Serve in San Bruno
We run jobs throughout San Bruno, from the flat streets near Tanforan up the hill into Portola Highlands and the ridge side of Crestmoor. Each area has its own rhythm: the older tract homes near downtown need more frame repair, the hillside subdivisions need more flashing and drainage work, and the newer builds off Sneath Lane mostly follow current code.
