Window Company in Costa Mesa, CA
Westlight Windows & Doors replaces and installs windows and doors throughout Costa Mesa, and this page is the best place to start if you’re weighing window or door work on a home here. Costa Mesa’s housing stock is mostly 1950s through 1980s tract homes, many with original aluminum frames and single-pane glass that have spent decades in coastal salt air. After thirty or forty years of marine layer and UV exposure, most of those frames are pitted, the seals are blown, and the tracks are too rough to slide. We give every Costa Mesa homeowner a written price before any work begins, and you can reach a live person at (424) 414-2048 any time, day or night. For the full picture on each service, see our dedicated Window Replacement in Costa Mesa, Window Installation in Costa Mesa, and Door Installation in Costa Mesa pages.
Why Costa Mesa Homes Are Different
Costa Mesa sits close enough to the Pacific that the morning marine layer is a fact of life, and with it comes salt-laden air that settles on metal surfaces year-round. Aluminum window frames, sliding door tracks, and door hardware here corrode faster than they do a few miles inland, so any replacement should be built around materials that can handle chloride exposure. We recommend corrosion-resistant frames and stainless hardware on most Costa Mesa jobs, and we’re specific about flashing details because coastal moisture finds its way into openings that dry-climate contractors treat casually.
The typical Costa Mesa home is a single-story ranch or two-story tract build from the 1950s through the 1970s. Many still have the original single-pane aluminum sliders, and in the Mesa Verde and College Park tracts, the 1960s sliding doors often arrive with tracks so pitted from decades of salt air that the rollers catch and the door binds. Newer infill construction in Costa Mesa trends the other direction: contemporary custom homes with large expanses of glass, often multi-panel stacking sliders and fixed picture windows that need precise leveling on raised foundations. The job changes from block to block, which is why our Costa Mesa estimates always start with a site visit rather than a phone-only quote.
Our Main Costa Mesa Services
The three jobs Costa Mesa homeowners call us about most are full window replacement, new-construction or major-remodel window installation, and entry or patio door installation. Each has its own Costa Mesa page with detailed pricing, local conditions, and specific FAQs.
Window Replacement in Costa Mesa
Replacing original aluminum windows in a 1960s Costa Mesa ranch means pulling frames that may have been moisture-wicking for fifty years, repairing any rot at the sill, and setting new units with proper flashing so the marine layer doesn’t work its way back in. We carry eight manufacturer lines, including impact-rated PGT and CGI, so the right glass gets matched to the exposure: a west-facing window on a Mesa Verde street takes more afternoon sun than an east-facing bedroom in College Park, and the coating choice changes with it. Low-e glass (a thin coating that reflects heat back into the room in winter and back out in summer) is standard on most of our Costa Mesa replacements. Full details are on the Window Replacement in Costa Mesa page.
Window Installation in Costa Mesa
Window installation in Costa Mesa often means new openings, not just swaps, because so much of the recent building here is custom contemporary work with large fixed and mulled units. These jobs need extra framing coordination and load calculations, especially on second-story walls facing the ocean breeze. For tract homes where a window is being added or enlarged, Costa Mesa’s planning rules and HOA requirements can both come into play, and we handle the paperwork so the installation doesn’t stall. See the Window Installation in Costa Mesa page for what’s involved, from rough opening through trim.
Door Installation in Costa Mesa
Door installation in Costa Mesa splits into two very different jobs: replacing a weathered entry door with a new pre-hung Therma-Tru unit, or replacing an original aluminum slider whose track and rollers have been eaten by salt air. Slider work usually means pulling the old frame completely and addressing any corrosion at the threshold. Entry doors on older Costa Mesa homes sometimes sit out of square after decades of minor settling, so the pre-hung unit has to be shimmed and sealed carefully or the door binds within a year. Full pricing and process details are on the Door Installation in Costa Mesa page.

Coastal conditions push Costa Mesa pricing up in one predictable way: older aluminum frames that have been corroding for decades often hide rot or moisture damage behind the rough opening, and that repair work gets added to the job before the new unit goes in. The Kingswell Guarantee means the number we write on your proposal is the number you pay; we don’t revise quotes at the door. If a repair fails within the guarantee period, Westlight returns and corrects it at no charge.

Yes. For replacement in kind, Costa Mesa rarely requires a permit, but HOA reviews are common in the tract communities, and we handle the paperwork and any pre-approval submittals. For new openings or structural changes, we pull the permit and coordinate inspections. The written quote includes any permit fees, so there’s no surprise line item later.

What Costa Mesa Customers Say
"Our sliding patio door had come off its track years ago and we just lived with it. New one is smooth as butter. They hauled off the old one and vacuumed up before they left."
- Jessica Landry"Our energy bill in summer was brutal. New windows made a real dent in it. Salesman wasn't pushy and didn't do the fake "today only" discount thing the others tried."
- Bethany Oh"Two bedroom windows that never opened and one that wouldn't stay up. All replaced in an afternoon. The crew was clean, hauled off the old frames, and the quote held."
