AfterWindow Company in Palo Alto, CA
Westlight Windows & Doors is the Palo Alto window company built around a simple promise: a written price before any work starts, a real arrival window, a clean job site, and a written guarantee handed to you when the job is done. Palo Alto homes are not one-size-fits-all. From 1920s Craftsman bungalows in Old Palo Alto to mid-century Eichler glass walls in Greenmeadow, this city demands products and install methods that most contractors never stock. Call (903) 354-7134 for a free estimate and we’ll talk through what your house actually needs.
Why Palo Alto Homes Are Different
Palo Alto sits inland enough from the Bay that summer afternoons routinely reach the high 90s to low 100s°F, far warmer than Menlo Park or Redwood City just a few miles west. That means solar heat gain coefficient, or SHGC (how much heat the glass lets through), is a real specification on south- and west-facing windows here, not a marketing footnote. Morning marine layer condensation cycles on older single-pane aluminum frames are another recurring issue, especially in Eichler homes, where that moisture accelerates frame corrosion and seal failure year over year.
The housing stock spans three very different eras. Old Palo Alto and Professorville hold 1920s to 1940s Craftsman and Colonial Revival homes, many protected by City of Palo Alto architectural review in the Professorville historic district. Greenmeadow contains one of California’s largest intact Eichler tracts, where post-and-beam construction and floor-to-ceiling glass panels make standard vinyl replacements structurally and aesthetically incompatible. And post-2000 luxury rebuilds across the city demand high-specification products, fiberglass, thermally broken aluminum, and triple-pane glass, even where code would allow far less. Each of these requires a different approach, and a different product line.
Our Main Palo Alto Services
These are the two jobs Palo Alto homeowners call us about most, each with its own dedicated page where you’ll find specific pricing and process details.
Window Replacement in Palo Alto
Replacing windows in Palo Alto often means working around architectural review in Professorville or structural constraints in Greenmeadow Eichlers, where window openings are load-bearing and the original aluminum frames are tied directly into post-and-beam construction. We stock thermally broken aluminum and specialty mid-century profiles specifically for these homes, alongside high-efficiency options for newer builds. Owen Satterfield and our team walk every job before quoting so the written price reflects what’s actually behind the drywall. Window Replacement in Palo Alto covers full details.
Window Installation in Palo Alto
New window installation in Palo Alto ranges from fitting modern triple-pane units into recent luxury rebuilds to retrofitting aging single-pane frames in 1950s Eichlers. Morning condensation cycling on old aluminum is one of the most common drivers we see, and proper flashing is the difference between a window that lasts twenty years and one that leaks in five. We carry eight manufacturer lines so the product matches the house, not the reverse. Window Installation in Palo Alto explains what each job involves.
Door Installation in Palo Alto
Door installation in Palo Alto frequently involves Eichler sliding glass doors whose original 1950s aluminum tracks were set directly into concrete slab thresholds. Replacing those tracks often means custom threshold transitions and a structural permit, a quirk that catches out-of-area crews on nearly every Greenmeadow project. We’ve worked through that inspection process enough times to quote it accurately up front. Entry door replacement in older Palo Alto homes brings its own set of framing and leveling challenges. Door Installation in Palo Alto has the specifics.

Eichler work pushes prices up because the structural glass walls and slab-set tracks demand custom fabrication and often a permit. Professorville historic district jobs also run higher due to architectural review and period-appropriate material requirements. Whatever the scope, your price is written down before any work begins, and it does not change at the door.

What Palo Alto 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
