Window Company in Los Angeles, CA
Westlight Windows & Doors is the Los Angeles window and door company that puts every price in writing before work begins. Window and door jobs across Los Angeles carry real complications most homeowners don’t see coming until the crew is already there: stucco exteriors that crumble at the rough opening, 1950s steel casements rusted shut in hillside homes, and building code that treats glass anchoring as a seismic issue. Owen Satterfield leads the team, and we answer the phone 24/7. Call (213) 810-3461 to get your written quote started.
Why Los Angeles Homes Are Different
Los Angeles window and door work is shaped by three things other cities just don’t face in the same way. First, the housing stock. A huge share of single-family homes here were built before 1980, and many still carry original wood-frame windows, aluminum sliders, and stucco exteriors that hide surprises behind the trim. Removing an old frame in a Los Angeles stucco wall often means the opening is no longer square, so flashing has to be cut and bent on site rather than pulled off a shelf. Second, the climate. Months of direct sun break down seals, warp vinyl, and fade anything facing south or west, while Santa Ana wind events test every weatherstrip and anchor point. The mild winters also mean many older Los Angeles homes were built with little insulation and single-pane glass, so energy costs get dragged upward by cooling loads in summer. Third, the terrain. In hillside neighborhoods like Mount Washington and others along the 110 corridor, original steel casement windows have rusted into place over decades, and replacement calls for custom fabrication because the rough openings were never built to modern dimensions.
Seismic code compliance runs through all of it. Los Angeles requires glass and frame anchoring that holds up in a quake, which is why we lean on impact-rated products from PGT and CGI alongside properly tied anchors. A sash replacement is never just swapping glass here; it’s making sure the whole assembly stays in the wall when the ground moves.
Our Main Los Angeles Services
Most Los Angeles homeowners call us about two things: replacing windows that have been failing for years, and putting in new doors or windows during a renovation. Below are the three services we run out of our Los Angeles office.
Window Replacement in Los Angeles
Replacing windows in Los Angeles usually means pulling out aluminum sliders or wood sashes from the 1970s and earlier, resizing the rough opening if it’s drifted out of square, and setting a properly flashed unit that holds up to UV exposure and the occasional wind event. We replace like-for-like where it makes sense and upgrade to low-e glass where cooling costs are the driver. This is our most-booked Los Angeles trade, and the page dedicated to it walks through the full process and pricing: Window Replacement in Los Angeles.
Window Installation in Los Angeles
New window installation covers the jobs where the wall opening is brand new or being reshaped, which happens a lot in Los Angeles additions and ADU builds. We frame and flash for stucco and post-and-beam conditions common across the city, and we match the glass to the exposure. If you’re working with a general contractor, we coordinate the opening dimensions before the walls go up so the windows aren’t rushed at the end. Read the full breakdown here: Window Installation in Los Angeles.
Door Installation in Los Angeles
Door installation in Los Angeles covers entry systems and exterior doors that see hard sun on the west side and seismic movement everywhere. We routinely replace rusted or sagging hinges, adjust jambs that have shifted, and set new slabs with proper sill flashing so the first rain doesn’t leak through. Product selection runs from Therma-Tru entry doors to specialty lines when the job calls for it. See the dedicated Los Angeles page here: Door Installation in Los Angeles.
