Window Company in Stanford, CA
Westlight Windows & Doors is the window company Stanford homeowners call when the job has to be done right the first time. We replace, install, and service windows and doors across the Stanford area, and we’ve learned what makes these homes different: original 1920s steel casements in Professorville, wood-framed double-hungs on faculty housing built between the wars, and campus-adjacent properties where Stanford University Building Standards add a layer of requirements most contractors never see. If you’re pricing a window or door project in Stanford, call (669) 333-7786 for a written quote before any work starts.
Why Stanford Homes Are Different
Stanford’s Mediterranean climate does a number on wood window frames. Cool, wet winters swell sashes and rot sills, then dry summers shrink and crack them. After eighty or ninety cycles of that, original windows from the 1920s and 1930s often need more than a caulk line. We regularly see failed glazing putty, warped stiles, and weatherstripping that crumbled years ago on the double-hungs and casements common to Stanford faculty housing.
Professorville is its own category. Many of those homes still carry original steel casement windows from the 1920s. Steel frames rust, glass channels seize, and replacements are not sitting on a shelf at the supply house. They require custom fabrication or careful restoration using compatible profiles, and that work has to respect the historic character of the street. The wrong unit changes the look of the house from the curb, and Stanford homeowners notice.
For campus-adjacent properties, the Stanford University Building Standards govern window and door work, supplementing or overriding local codes in places. Legacy sandstone and tile-roofed buildings often require historic-compatible materials and specific energy-efficiency upgrades. If your project falls under those standards, we’ll work through the requirements with you before anything gets ordered.
Periodic drought years also push many Stanford homeowners toward low-e glazing and modern weatherstripping to cut HVAC load during dry summer stretches. The right glass coating keeps heat out in July and holds it in during January.
Our Main Stanford Services
Stanford homeowners call on us most for two things: replacing windows that have outlived their frames and installing doors that seal and hang properly. Here’s what each involves in this area.
Window Replacement in Stanford
Replacing windows on a 1940s Stanford Colonial or a Professorville original means matching frame profiles, trim dimensions, and sightlines that were set decades ago. We carry eight manufacturer lines, including PGT and Eco Window Systems, so the replacement unit suits the house rather than forcing the house to suit whatever’s in the truck. Energy codes and campus building standards sometimes add requirements, and we handle those on the front end. Window Replacement in Stanford has the full breakdown.
Window Installation in Stanford
New window installation in Stanford ranges from retrofit inserts in standard openings to full-frame installs on homes where rot or settling has compromised the rough opening. Older faculty housing often has out-of-square openings that need shimming and flashing done properly or the new unit will bind. On Professorville steel casements, installation often involves custom-fabricated replacements measured to the existing masonry opening. Window Installation in Stanford covers what to expect.
Door Installation in Stanford
Entry doors on Stanford’s older homes take direct sun on the west side and steady damp from winter rains. We install entry doors, patio sliders, and security doors, and we see real differences in how well a door holds up depending on the hardware and threshold detailing. Therma-Tru entry systems hold up well in this climate when flashed and sealed correctly. Door Installation in Stanford has pricing and product details.

"Windows are great and the install was solid. One of the installers was quieter and didn't explain much, but the lead walked me through everything at the end and made sure I was happy."
- Lamar Jennings"Front door was swollen and wouldn't latch half the year. New door and frame, done in a day. Looks great and actually seals. Written price didn't budge."
- Renee Saldana"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."
