Window Company in University of California-Davis, CA
Westlight Windows & Doors replaces and installs windows and doors across Davis, and most jobs here come down to one thing: keeping a 1970s ranch house livable through a Sacramento Valley summer without running the AC nonstop. We’re an independently owned and operated Kingswell location, which means every job starts with a written price before any work begins and ends with a written guarantee in your hand. If you’re looking at failed seals, sticking sliders, or a front door that no longer closes square, call (903) 354-7134 and we’ll walk you through what it takes.
Why University of California-Davis Homes Are Different
Davis nights are built around the delta breeze. That’s the cool air that rolls in from the Sacramento-San Joaquin Delta after sundown, and generations of Davis homeowners have used it to flush out 100°F-plus afternoons by opening windows instead of cranking the thermostat. That only works when casement cranks turn, double-hungs stay where you put them, and screens keep moths and mosquitoes out. A seized operator or a blown-out screen in July isn’t a cosmetic problem here; it’s the difference between a 68°F bedroom and an 82°F one at midnight.
Most of the housing stock feeding into those breezes dates from the 1960s through the 1980s, built during UC Davis’s big enrollment expansions. Ranch and tract homes with original aluminum single-panes and aging sliding glass doors are everywhere, and a large share have spent years as student rentals where deferring maintenance was the financial default. By the time someone calls us, window hardware is often a decade past functional, door rollers are ground flat, and weatherstripping has turned brittle. The delta breeze that makes Davis unique also finds every gap in an old assembly.
We also see what the flat Yolo County terrain does to exterior openings. Afternoon valley winds push steadily against west-facing doors and windows, accelerating seal wear and pulling frames slightly out of square. Homes on the west and north edges, the ones bordering UC Davis research fields and working farms, collect a fine agricultural dust that packs sliding door tracks solid and abrades vinyl seals. You won’t see that failure mode two miles east in Woodland. It’s a Davis problem, and it changes which products we recommend.
Our Main University of California-Davis Services
The two calls we take most from University of California-Davis homeowners are for replacement windows and for doors that no longer operate the way they should. Each has its own page below with pricing and what to expect.
Window Replacement in University of California-Davis
Replacing original single-pane aluminum with modern low-e glass (a thin coating that reflects heat back the way it came) is the single biggest comfort upgrade a Davis ranch home can get. We focus on low-solar-gain glazing for west- and south-facing openings because those catch the hardest Valley sun, and we match the product to the exposure rather than putting the same glass in every opening. See the full breakdown, including typical Davis price ranges, on our Window Replacement in University of California-Davis page.

Window Installation in University of California-Davis
Some homes need glass replaced in existing frames, while others are better served by a full tear-out and new-construction install. In Davis, we also pay close attention to screen condition and operability during any installation, because if the window can’t open smoothly on a delta-breeze night, the job isn’t finished. We walk you through both paths and what each costs before you commit. Details are on our Window Installation in University of California-Davis page.

Door Installation in University of California-Davis
Years of steady valley wind and tracked-in field dust are hard on Davis entry doors. Thresholds wear, hinges sag, and slider rollers grind themselves flat. We install Therma-Tru entry systems and match the door to the exposure, because a west-facing front door in Davis takes far more afternoon punishment than the same door in a shaded Sacramento street. Get specifics and pricing on our Door Installation in University of California-Davis page.

Brands We Service in University of California-Davis
We carry eight manufacturer lines and install PGT and CGI impact-rated products, ViewLux, and CWS among them, which lets us match the product to the exposure instead of the other way around. Common parts for these lines are stocked locally in our service vehicles, so most hardware repairs don’t wait on a freight shipment. See our brands for the full list.

- Craig Dillard"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."
