AfterWindow Company in Los Gatos, CA
Westlight Windows & Doors handles window replacement, window installation, and door installation across Los Gatos, from the flatland Craftsman bungalows near downtown to the hillside estates along Kennedy Road and up toward Lexington Reservoir. Los Gatos jobs are different from neighboring towns because of two overlapping realities: the Town’s Historic Preservation Committee reviews most visible exterior changes on pre-1930s homes, and hillside parcels above roughly 400 feet fall under California’s Wildland-Urban Interface fire codes. That combination means the right window or door here is rarely the one a big-box store sells off the shelf. If you’re pricing a project, call (903) 354-7134 and we’ll walk you through what actually applies to your street.
Why Los Gatos Homes Are Different
The housing stock in Los Gatos splits into two distinct groups, and each brings its own complications. Downtown and the old-town grid hold late-1800s to 1930s Victorians, Craftsman bungalows, and Colonial Revivals, many still carrying original wood sash windows. The Historic Preservation Committee reviews exterior alterations on these homes, and they routinely reject standard vinyl replacements that fail to replicate the original wood profiles and sightlines. We’ve helped homeowners navigate that review by specifying products that match the character without sacrificing performance.
Then you have the foothills. Belgatos, Kennedy Road, and the slopes rising toward Lexington Reservoir sit inside the Santa Cruz Mountains’ Wildland-Urban Interface. Building code there mandates ember-resistant, fire-rated glazing and non-combustible or ignition-resistant frames, because ember cast from a ridge fire is a genuine threat, not a theoretical one. A standard vinyl slider package sold freely in San Jose fails that WUI review outright. Compounding matters: the Loma Prieta earthquake epicenter in 1989 sat just a few miles from town, and some older Los Gatos homes still carry slightly racked or shimmed rough openings from that event, which complicates retrofit work when a new window or door is set into a frame that is not perfectly square.
Our Main Los Gatos Services
Most calls we take from Los Gatos homeowners come down to two situations: a window or door has failed and needs replacement, or a remodel or addition calls for new openings and new units. Here’s how each works in this town.
Window Replacement in Los Gatos
Replacing windows in Los Gatos means pulling the old sashes and setting new units into existing openings. On a downtown Craftsman or Victorian, we match the original muntin patterns and wood profile so the Town’s design review does not stall your project. On a hillside home, we document WUI-compliant framing and glass so the inspector’s compliance check goes through the first time. The work is measured to your actual rough opening, which matters in a town where 1989 left some openings slightly out of square. Window Replacement in Los Gatos
Window Installation in Los Gatos
New window installation in Los Gatos typically comes up with additions, remodels, and new construction on foothill lots. The job is different from replacement: the rough opening gets framed, flashed, and sealed before the window is set, which means the waterproofing detail matters as much as the glass. Hillside exposures along the Highway 17 corridor get strong downslope winds and hard afternoon sun, so we pay close attention to flashing and sealant specification on the west-facing elevations.

Door Installation in Los Gatos
Entry doors in Los Gatos range from period-appropriate wood doors on old-town homes to custom iron and glass pivot doors on the ridgeline estates. Historic review applies downtown; WUI ignition-resistance requirements apply above 400 feet. We set the door, adjust the threshold, and make sure the reveal is even so the door actually latches properly and seals against the canyon winds. Door Installation in Los Gatos

What pushes a Los Gatos price higher than a Campbell or Santa Clara quote is usually WUI compliance on the hillside or historic-review requirements downtown. Either way, you get your written price before any work starts, and that price does not change at the door.

FAQs About Window Company in Los Gatos
Yes, in most cases. Hillside parcels above roughly 400 feet elevation trigger a WUI compliance check, and downtown homes in historic districts need design review before exterior changes proceed. We handle the paperwork and know what the Town’s inspector will ask for.
The Historic Preservation Committee reviews proposed exterior changes on contributing structures, which usually means any visible window or door replacement. The review looks at profile, sightlines, materials, and muntin patterns. We can help you build a submittal package that gets approved without multiple rounds. Call (903) 354-7134 to talk through your specific block.
Yes. Above the elevation threshold, the Town requires ember-resistant, fire-rated glazing and non-combustible or ignition-resistant framing. Standard vinyl sliders sold in San Jose fail that review. We specify compliant products up front so the inspection runs clean the first time.

What Los Gatos 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
