Window Company in Sunnyvale, CA
We’re Westlight Windows & Doors, an independently owned and operated Kingswell location serving Sunnyvale homeowners since our founding in 2009. What makes window and door work different here comes down to the housing stock: thousands of mid-century ranch and Eichler-style homes with floor-to-ceiling glass, thin aluminum frames, and sliding doors that have been fighting the weather for fifty or sixty years. Call (669) 333-7786 and you’ll reach a live person, not a voicemail box.
Why Sunnyvale Homes Are Different
Sunnyvale developed heavily between the 1950s and 1970s, which means most of the city is single-story ranch homes, Eichler-inspired designs with large glass walls, and a smaller share of 1980s and 1990s two-story stucco builds. Many of those original aluminum or wood window frames are still in place today, often with single-pane glass and frames that leak air at every seam. In the Birdland and Cherry Orchard neighborhoods especially, homeowners call us about original Eichler sliding glass doors that stick, bind, and let winter drafts pour through the track.
The climate compounds the problem. Sunnyvale’s Mediterranean pattern means cool, wet winters followed by dry, sunny summers with real UV load and occasional heat spikes. That combination rots wood frames, fades finishes, and causes condensation to pool on old single-pane glass every winter morning. Most of the work we quote in Sunnyvale is a dual-pane retrofit: new glass and frames that stop the drafts and the condensation while keeping the original architectural character. The west light in Sunnyvale is the late-afternoon sun that pours through a good window, and in an Eichler with a wall of glass, getting that light right matters.
Our Main Sunnyvale Services
Most Sunnyvale homeowners reach out about one of two things: windows that need replacing, or doors that need installing. Each service has its own dedicated Sunnyvale page with local pricing and specifics.
Window Replacement in Sunnyvale
Window replacement in Sunnyvale usually means pulling out original single-pane aluminum or wood frames and putting in dual-pane units that handle the winter condensation and summer UV that older glass never could. The trick with mid-century homes is matching the original sightlines: many Birdland homeowners want the new frame to look like the old one, only better sealed. Learn more on our Window Replacement in Sunnyvale page.
Window Installation in Sunnyvale
Window installation in Sunnyvale often involves new-construction or full-frame installs for remodels, additions, or homes where the rough opening needs rework before new glass goes in. On Eichler-inspired designs with large glass sections, we pay close attention to the load path and the seal detail so the new unit doesn’t just look right, but stays square and watertight through years of Bay Area weather. See our Window Installation in Sunnyvale page for specifics.
Door Installation in Sunnyvale
Door installation in Sunnyvale covers entry doors, patio sliders, and the oversized glass door systems that many mid-century homes were built around. The original sliding doors in Cherry Orchard and Birdland are a common failure point: worn rollers, warped tracks, and failed seals that let air move freely through the house. Our Door Installation in Sunnyvale page covers what the job costs and how we approach custom retrofit work.

Pricing for Window Company in Sunnyvale, CA
| Service | Typical range in Sunnyvale |
|---|---|
| Single-window replacement (standard size, vinyl frame) | $850 – $1,400 installed |
| Single-window replacement (large Eichler-style fixed glass) | $1,800 – $3,200 installed |

In Sunnyvale, the price moves most when the opening is oversized (common in Eichler-style glass walls), when the existing frame is rotted and needs structural repair, or when a homeowner wants impact-rated glass to match existing CGI or PGT units. Every figure above is a planning range: your written price comes before any work starts, and it does not change at the door.

FAQs About Window Company in Sunnyvale
We pull the permits when the scope requires them under Sunnyvale building codes, and we close them out after inspection.

Most Sunnyvale homeowners can get on our schedule within two to four weeks, depending on product lead times and whether the job involves custom sizing. A standard retrofit is usually faster than a full-home replacement or a large custom door. Call (669) 333-7786 for a specific window.

"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."
