AfterWindow Company in San Bernardino, CA
Westlight Windows & Doors is the San Bernardino window company built for homes that take a beating from the Cajon Pass. We replace and install windows and doors in postwar tract houses that still carry their original single-pane aluminum frames, in neighborhoods where 105°F summers and wind-driven Mojave grit punish every seal and roller. If your windows are original to a home built between 1948 and 1975, they’re leaking conditioned air and working against you every month. Call us at (903) 354-7134 and we’ll give you a written price before any work starts – not after.
Why San Bernardino Homes Are Different
San Bernardino sits directly in the path of Santa Ana winds funneling through the Cajon Pass just north of the city. Documented gusts exceeding 60 to 80 mph put sustained wind loads on window glass and door frames that neighboring Riverside or Ontario rarely see. That same corridor pushes fine Mojave desert particulate into weatherstripping, track channels, and door jamb gaps, degrading them measurably faster than in wind-sheltered parts of the Inland Empire.
The housing stock compounds this. Most San Bernardino homes were built between the late 1940s and mid-1970s, and the majority still have original single-pane aluminum-frame windows with no thermal break. Decades of thermal cycling in 105°F-plus summers have left those frames dimensionally non-standard and structurally tired, so direct replacement is more labor-intensive than it would be in newer markets. Up against the San Bernardino National Forest, many northern neighborhoods also fall inside CAL FIRE’s Wildland-Urban Interface fire hazard severity zones, where replacement windows and exterior doors need ember-resistant assemblies you won’t find specified deeper in the valley.
Our Main San Bernardino Services
Most San Bernardino homeowners call us about two things: windows that are failing in the heat and wind, and doors that no longer seal or slide the way they should. Each service has its own page with full pricing and local detail.
Window Replacement in San Bernardino
Replacing original single-pane aluminum frames in San Bernardino tract homes means working with openings that have shifted over 50 to 70 years of thermal cycling. We measure every opening individually and specify frames sized to the actual rough opening, not the original label. In WUI-designated neighborhoods near the National Forest boundary, we also make sure the replacement units meet ember-resistant assembly standards. Read the full breakdown at Window Replacement in San Bernardino.
Window Installation in San Bernardino
When you’ve already bought the windows or need a crew to install units in a new addition or remodel, we handle the installation with the same written-price process. San Bernardino’s extreme diurnal temperature swings – 105°F days followed by 20-degree overnight drops – mean the sealant and flashing details matter more than most homeowners realize. We spec materials that hold up to that expansion and contraction. Get the specifics at Window Installation in San Bernardino.
Door Installation in San Bernardino
Exterior doors in San Bernardino work harder than anywhere else in the Inland Empire. The Cajon Pass wind corridor blasts ultra-fine desert grit into sliding patio door tracks, where it seizes rollers years ahead of schedule. We spec sealed-bearing roller hardware and clean and re-lubricate tracks as a standard part of every door service call – a step most installers trained in coastal markets never learn. Full detail is on the Door Installation in San Bernardino page.

Brands We Service in San Bernardino
We carry and install eight manufacturer lines, so the product matches the job rather than the other way around. For San Bernardino’s wind and WUI requirements, we commonly specify impact-rated our brands like PGT and CGI, plus CWS and ViewLux for replacement projects that need a particular look. Turnaround on standard orders is predictable because we keep common sizes and parts stocked locally.

What San Bernardino 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"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
