Window Company in Westminster, CA
Meridian Windows & Doors handles window replacement, window installation, and patio door installation for homes across Westminster, CA. Most homeowners here live in single-family houses built between the mid-1950s and late 1970s, which means original aluminum-frame windows that have been through fifty-plus summers of Southern California sun. That aging stock, combined with Westminster’s coastal-adjacent climate, drives most of the calls we get. If you’re weighing replacement windows or a new patio door, call (817) 686-2228 and we’ll put a written price in front of you before any work starts.
Why Westminster Homes Are Different
Westminster’s housing stock skews older than nearby Fountain Valley or Huntington Beach. A large share of homes were built during the post-war boom, and many still have their original single-pane windows. That matters for two reasons: first, those frames warp over time, so a straightforward sash replacement can turn into a full-frame job once we open the wall. Second, single-pane glass does almost nothing to block the heat that builds up on streets like those off Bolsa Avenue in July and August.
The marine layer is another factor. Westminster sits about six miles inland, close enough to the coast that morning fog rolls in regularly, but far enough that afternoon temperatures climb into the 80s and 90s. Windows here need to handle humidity without swelling, and glass coatings need to reflect heat without making rooms feel dim. We spec low-E glass (a thin coating that reflects heat while letting light through) on most Westminster replacements for exactly that reason.
Some neighborhoods, particularly older pockets south of Westminster Boulevard, have original wood-frame window openings that are no longer square. That’s normal for homes this age, and it means the installer matters as much as the window. We measure every opening twice before ordering, and we build out the frame rather than forcing a stock size into a crooked hole.
Our Main Westminster Services
Window replacement and window installation are the two jobs Westminster homeowners call about most, followed closely by patio door work. Each has its own page with full pricing and details, linked below.
Window Replacement in Westminster
Replacement work in Westminster usually means removing original aluminum or wood sashes and swapping in new energy-efficient units, often full-frame jobs because the old frames have sagged. Homes near the Westminster Mall and along Goldenwest Street tend to have larger picture windows that face afternoon sun, so glass selection drives both comfort and the final price. We pull the old unit, inspect the rough opening for rot or settled framing, and set the new window square before sealing and trimming. Window Replacement in Westminster covers the full scope and local pricing.

Window Installation in Westminster
New installation comes up frequently in Westminster’s patio enclosures and room additions, where homeowners are adding square footage rather than swapping what’s already there. The work runs from cutting and prepping rough openings to flashing, setting, and finishing. Westminster’s older stud spacing sometimes means reframing an opening to meet current code, and we handle that rather than leaving an undersized header in place. Window Installation in Westminster walks through what a new-opening job involves here.

Patio Door Installation in Westminster
Many Westminster backyards open onto a covered patio, and the door between them is usually a worn aluminum slider with a track that drags. Replacing it changes how the whole back of the house works. We install sliding, French, and bi-fold patio doors, leveled and sealed against Westminster’s morning damp and afternoon heat. Patio Door Installation in Westminster details product choices and what the job takes from start to finish.
