Window Company in Oakland, CA
Westlight Windows & Doors is the Oakland window and door company built around a simple idea: the west light, that late-afternoon sun that pours through a good window, is bright, warm, and worth doing right. Oakland homes demand more from windows and doors than most Bay Area properties, and we match the right product to the job every time. From fog-worn Craftsman bungalows in Fruitvale to hillside homes in the fire zone above Highway 13, replacement work here has to account for things contractors in San Leandro or Emeryville never deal with. Call (903) 354-7134 and you’ll reach a live person who can talk through your project.
Why Oakland Homes Are Different
Oakland splits into two regulatory worlds within the same city limits. Hillside parcels above Skyline Boulevard and along much of Highway 13 fall under CAL FIRE’s Very High Fire Hazard Severity Zone mapping, which means Chapter 7A-compliant multi-pane tempered glazing and fire-rated door assemblies are legally required. Flatlands homes in Temescal, Fruitvale, and East Oakland follow standard Title 24 coastal energy rules. That dual-regime reality doesn’t exist in neighboring Alameda, Piedmont, or San Leandro, and it changes material costs by 20 to 40 percent depending on where a parcel sits.
The housing stock is just as split. The flatlands are packed with 1920s through 1950s Craftsman bungalows and Edwardian flats still carrying original single-pane wood double-hung windows, most of them badly out of square after a century of settling. Up in the hills, a large share of homes rebuilt after the 1991 Tunnel Fire are now 30-plus years old and entering their first full replacement cycle. On top of that, the Hayward Fault runs directly through the Oakland Hills, so door and window installations there routinely encounter frame racking and out-of-square openings that require shimming, reframing, or custom sizing before new units go in.
Oakland’s marine microclimate adds another layer. Persistent morning fog in the hills sits against wood frames and accelerates rot and failed IGU seals. Down near the Estuary and Jack London waterfront, salt-laden Bay breezes corrode aluminum hardware noticeably faster than inland East Bay cities. Frame material selection matters more in Oakland than in almost any comparable California market.
Our Main Oakland Services
Three services make up the core of what Oakland homeowners call us for. Each has its own detailed Oakland page below.
Window Replacement in Oakland
Most Oakland window replacement work starts with a truth homeowners already know: the original single-pane units in a 1920s bungalow were never square, and after decades of fog, Bay salt, and settling, they’re not getting better. We measure every opening individually, because in Fruitvale and East Oakland especially, no two are alike. Hillside parcels in the VHFHSZ require Chapter 7A glazing, and we confirm that designation before quoting so the price holds at permit submittal. Full details, including pricing, are on our Window Replacement in Oakland page.

Window Installation in Oakland
Window installation in Oakland often means working around conditions that other Bay Area cities don’t have. Out-of-square openings from fault-line settling, fog-worn sills that need repair before a new frame can sit properly, and hillside access constraints all shape the job. We carry units from ECO Window Systems and Mr-Glass that fit both the flatlands’ Title 24 energy requirements and the hills’ tougher fire-zone needs. The written price you get before work starts is the price you pay. See the full scope on our Window Installation in Oakland page.

Door Installation in Oakland
Entry door installation in Oakland shifts depending on where the home sits. Hillside properties in the VHFHSZ need fire-rated door assemblies; flatlands homes near the Estuary need frame materials that hold up to salt air. We install Therma-Tru entry doors and ViewLux units, matched to the specific exposure and code requirements of each address. Every door gets a written price up front and a written guarantee when the job is done. The full rundown is on our Door Installation in Oakland page.

Brands We Service in Oakland
We stock and install ViewLux, PGT, CGI, and CWS product lines, which lets us match the right window or door to Oakland’s specific conditions rather than forcing one brand onto every job. Parts for these lines are stocked locally, and most hardware orders turn around in days, not weeks. See our brands for the full breakdown of what each line offers.

Every quote Westlight gives is written, line-itemed, and fixed before work starts. No door-step revisions, no revised invoices.

What Oakland 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
