Window Company in Palm Desert, CA
Westlight Windows & Doors is a window company serving Palm Desert, CA with window replacement, window installation, and door installation. The desert puts real stress on a home’s glazing: summers above 110°F, relentless UV, and 40-degree temperature swings that tear apart window seals faster than almost anywhere else in California. If your Palm Desert home has fogged glass, warped frames, or a slider that sticks, call (903) 354-7134 for a free estimate and a written price before any work begins.
Why Palm Desert Homes Are Different
Palm Desert sits in California Title 24 Climate Zone 15, one of the hottest-rated zones in the state. The fenestration SHGC requirements here (often ≤ 0.25) are stricter than what you’d find in Riverside or San Bernardino, which shapes every window decision we make. But the city’s stock of mid-century modern homes in the Cove neighborhoods and along Highway 111 adds another wrinkle: floor-to-ceiling glass walls, clerestory windows, and jalousie openings that look beautiful but leak energy. Homeowners in HOAs like Sun City Palm Desert or Ironwood Country Club often need replacements that hit aggressive thermal specs while keeping the original architectural character intact.
The other factor is seasonal. Many Palm Desert homes are snowbird residences, left vacant with the AC off from May through September. Windows bake at 110°F+ for months with no interior thermal buffering. The result: insulated glass unit seals fail, and October and November are the busiest repair months of the year as returning owners find entire walls of fogged glass waiting for them.
Our Main Palm Desert Services
These are the three services Palm Desert homeowners call us about most often. Each has its own dedicated page with local pricing, product notes, and what to expect on the job.
Window Replacement in Palm Desert
Most replacement work in Palm Desert involves pulling out original single-pane aluminum frames from the 1950s-1970s and putting in thermally broken units with low-e glass (a thin coating that reflects heat back out in summer and keeps interior heat in during winter). The SHGC rating matters more here than almost anywhere else in the state, and we carry product lines like PGT and CGI that meet those Title 24 thresholds without forcing a generic look.

Window Installation in Palm Desert
New-construction and addition work in Palm Desert runs into the same code wall: Climate Zone 15 specs are strict, and the windows have to perform before the first summer hits. We match the right product line, from ViewLux to CWS, to the spec the project demands rather than forcing a single brand onto every job. See what installation involves on our Window Installation in Palm Desert page.

Door Installation in Palm Desert
Sliding glass doors to pool decks are nearly universal in 1980s-2000s tract homes across Palm Desert, and they take a beating from sun and sand. We install Therma-Tru entry doors plus patio doors with frames and hardware built for the heat and UV conditions here. Get the full picture on Door Installation in Palm Desert.

What Palm Desert Customers Say
"Replaced eight drafty old windows that were basically single pane. The house is warmer already and the street noise is way down. Crew was on time both days and the price was exactly the quote."
- Harold Bemis"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."
- Colette Rhee
