Window Company in Larkfield-Wikiup, CA
Westlight Windows & Doors is a Larkfield-Wikiup window company that works on a housing stock shaped by fire. A large share of homes here were rebuilt after the 2017 Tubbs Fire under tightened WUI codes, while many surviving legacy homes still carry original aluminum single-pane windows. That split means we see two very different jobs in the same neighborhood: fire-rated retrofits on 1960s and 70s tract homes, and premature seal failures on dual-pane units installed quickly during the 2018-2020 rebuild rush. Call (903) 354-7134 for a written quote before any work starts.
Why Larkfield-Wikiup Homes Are Different
Larkfield-Wikiup sits in an inland Sonoma County corridor where summer Diablo wind events push temperatures into the upper-90s while humidity drops to single digits. Ember transport during those events makes window and door fire-resistance ratings a genuine life-safety issue here, not a code formality. Pre-fire Ranch-style and mid-century tract homes built between the 1960s and 1980s often still have single-pane aluminum frames and hollow-core doors that do not meet current WUI standards. Homeowners in those houses face real pressure from insurers and county requirements to retrofit.
The post-2018 rebuild cohort has its own problem. Many of those homes used code-minimum vinyl-frame fire-rated windows installed at speed. Four to six years on, we regularly see warped frames and failed IGU seals on those units. Wet, cool winters with wide seasonal temperature swings accelerate the thermal seal breakdown. A Larkfield-Wikiup homeowner who lived through the rebuild often knows exactly what we mean when we describe a second-wave replacement cycle.
Our Main Larkfield-Wikiup Services
Three services account for nearly every call we take from Larkfield-Wikiup homeowners. Each has its own page with pricing detail and a walkthrough of how the job runs.
Window Replacement in Larkfield-Wikiup
Replacing windows in Larkfield-Wikiup usually means pulling out old aluminum single-panes on legacy homes, or removing failing dual-pane vinyl units on post-fire rebuilds. The job often includes upgrading to dual-pane tempered glass to satisfy WUI fire-code requirements, plus low-e coatings (a thin layer that reflects heat back into the room in winter and out in summer). We quote the exact window model and frame material before work begins. Full detail is on the Window Replacement in Larkfield-Wikiup page.

Window Installation in Larkfield-Wikiup
Window installation here covers new-construction and retrofit work. On surviving older homes, we often find rough openings that have shifted over decades and need re-flashing before the new unit goes in. On rebuild-era homes, installation quality varies widely – some frames were set without proper drainage planes during the rush. We correct that before sealing anything. The Window Installation in Larkfield-Wikiup page covers the process and pricing in detail.

Door Installation in Larkfield-Wikiup
Door installation in Larkfield-Wikiup frequently involves replacing standard hollow-core entry doors with fire-rated assemblies, or upgrading sliders to impact-rated units on WUI-adjacent lots. We also handle interior door installs where rebuild-era work left frames out of square. Every door job gets a written price and a committed arrival window. See the Door Installation in Larkfield-Wikiup page for full scope and numbers.

What Larkfield-Wikiup Customers Say
"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"Two bedroom windows that never opened and one that wouldn't stay up. All replaced in an afternoon. The crew was clean, hauled off the old frames, and the quote held."
- Colette Rhee
