Window Company in Westlake Village, CA
Window and door work in Westlake Village follows a different set of rules than almost anywhere else in the Conejo Valley. Most homes here were built between 1967 and the mid-1980s as part of a master-planned lake community, which means we’re regularly replacing original aluminum single-pane windows and oversized sliding glass doors that have been baking in inland heat and taking Santa Ana wind gusts for 40 to 55 years. A big portion of the community also sits in a Very High Fire Hazard Severity Zone, so many replacements must meet California CBC Chapter 7A ember-resistance standards. If you’re pricing new windows or doors in Westlake Village, call us at (903) 354-7134 and we’ll walk you through what your specific home needs.
Why Westlake Village Homes Are Different
Westlake Village wasn’t built piecemeal over a century. The American-Hawaiian Steamship Company planned it as one continuous lake community, which is why so many streets share the same architectural DNA: Spanish Colonial, Mediterranean, and California ranch styles, most with rear walls of glass built to capture lake or hillside views. Those original aluminum-frame sliding doors and picture windows are now the biggest replacement target in the city. Their size is the kicker. A 12-foot sliding glass door costs far more to replace than a standard patio slider, both in product and in labor, and Westlake Village has a lot of them.
The climate speeds things up too. Westlake Village sits in an inland bowl, so summers run hotter and drier than what Malibu gets ten miles away. Diablo and Santa Ana wind events hit the area regularly, and they’re rough on weatherstripping and aluminum door frames. We see sliding doors that have racked out of square from years of wind pressure, and window seals that failed early because of the heat load. On top of that, the city straddles the Los Angeles-Ventura County line. A permit can come from the City of Westlake Village on one job and from Ventura County on a job a few blocks away, with different inspectors and different code interpretations. Experienced crews know to verify the county before scheduling anything.
Our Main Westlake Village Services
Most Westlake Village homeowners call us about one of three things, and each has its own dedicated page with local pricing and specifics.
Window Replacement in Westlake Village
Replacing original aluminum single-pane windows in Westlake Village usually means upgrading to dual-pane glass with low-e coatings, which cuts heat gain during Conejo Valley summers and quiets street noise. Many homes in the fire hazard zone also need tempered or fire-rated glazing to satisfy code and insurance requirements. Sizing matters here because original picture windows are often non-standard widths, so most jobs involve custom ordering rather than stock sizes. Owen Satterfield and our crew measure, order, and install to fit the existing openings without resizing the rough framing. See Window Replacement in Westlake Village for pricing and timelines.

Window Installation in Westlake Village
Window installation in Westlake Village covers new-construction windows in additions and remodels, plus retrofits where the old frame stays intact and the new unit slides into the existing opening. The county-line issue shows up here often. A project on the Los Angeles County side may run on a City of Westlake Village permit, while the same build a few blocks east needs Ventura County inspection. We handle the paperwork either way and coordinate inspections so the job doesn’t stall. Many homeowners building out their view walls also choose impact-rated glass from PGT or CGI for wind and fire resistance. Details are on Window Installation in Westlake Village.

Door Installation in Westlake Village
Door installation here skews toward oversized sliders and wide entry doors, because the original homes were designed around indoor-outdoor living. We install solid-core entry units that meet ember-resistance standards for homes in the fire hazard zone, plus new slider systems that glide instead of binding like the old aluminum frames. Weatherstripping gets a lot of attention in Westlake Village because Diablo winds find every gap. A properly hung door with good seals makes a real difference in July and September. Owen Satterfield can talk through material options, including Therma-Tru entry doors. See Door Installation in Westlake Village for more.

Brands We Service in Westlake Village
We install from eight manufacturer lines, so the product gets matched to the house rather than forcing the house to fit one brand. For Westlake Village homes we frequently recommend ViewLux for clean sightlines on view-facing walls, PGT or CGI for impact and fire-rated applications, and CWS for solid mid-range value. Parts for most lines are stocked locally through our supply chain, and standard orders typically land within two to three weeks. You can see the full range on our brands page.

We usually schedule estimates within one to three business days. Scheduling is coordinated from our Los Angeles office, with crews serving Westlake Village locally throughout the week. Call (903) 354-7134 and a live person will set a time window for your visit.
It depends on which county your home sits in. Jobs on the Los Angeles County side run through the City of Westlake Village, while Ventura County handles the other side, each with different inspectors and timelines. We verify the jurisdiction before scheduling any inspection. Replacement windows generally need permits for structural changes; simple retrofits often don’t, but we flag the requirement on every quote.
We don’t file HOA applications, but we’ll provide the product specifications and drawings your association needs to review. Many Westlake Village neighborhoods have design standards for window styles and door finishes, and we’re familiar with what those boards look for. Getting pre-approval before ordering products keeps the job from stalling.

What Westlake Village 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
