Fast, Reliable Windows & Doors Across Westlake Village
Window and door work in Westlake Village runs into two approval layers most homeowners never see coming: the city’s Chapter 7A fire-hardening standards and your HOA’s architectural review. We’ve been navigating both for years, and that’s why Windows & Doors jobs here go smoother with a local crew. Barrett & Sons Construction handles everything from the first measurement to the final inspection sign-off. Call (877) 610-1318 for a free estimate, and we’ll walk your street, look at your exposure, and tell you straight what the job needs.
Why Barrett & Sons Construction Is Westlake Village’s Preferred Windows & Doors Company
Tom Barrett founded this company in 1998, and his sons run the crews. That’s not marketing copy. When we say the owner answers the phone, we mean it, and when we say a written change order arrives before any scope change touches the job, that’s the only way we work. Westlake Village homeowners looking for our Driveway & Pavers in Westlake Village or other exterior work tend to be done with phone quotes that don’t match the final bill. Our price goes on paper before the first deposit, and the 90-Day Done Right Promise goes on every contract.
We know the 91359 and 91361 ZIP codes well. We know that a home off Triunfo Canyon Road with west-facing glass bakes in the afternoon sun differently than a shaded lot off Lakeview Canyon. We know the HOA in Westlake Village’s First Neighborhood has different exterior rules than the custom estate area on the north shore of the lake, just as Westlake Village Kitchen Remodeling projects face their own distinct permitting and design standards. That local familiarity shows up in the details: we check the original wood framing behind the stucco before ordering a single unit, because homes built between 1968 and 1985 hide surprises. We coordinate with your HOA’s architectural committee before you spend a dollar on materials you might not be allowed to install. And we pull permits on every eligible job, because the inspector works for you, not for me.
Our Windows & Doors Services in Westlake Village
Window Replacement
Most Westlake Village homes are forty to fifty-five years old now, and the original aluminum-frame windows have lived through five decades of Santa Ana winds and valley heat. Window replacement in Westlake Village typically runs $4,500-$15,000, depending on how many openings, whether the framing behind the stucco has dry rot, and whether the HOA restricts materials. We’ll tear out the old unit, inspect the rough opening, and tell you before we order if the job is bigger than it looks. Written change order first, always.

Impact Windows & Doors
The 2018 Woolsey Fire burned to Westlake Village’s doorstep. Anyone who was here remembers the sky. That’s why impact windows and doors aren’t just a resale feature here, they’re practical engineering. Impact window installation runs $8,000-$25,000, and for homes in the Very High Fire Hazard Severity Zone, the units have to satisfy Chapter 7A fire-resistant construction standards. We install dual-pane, fire-rated glass with ember-resistant framing. We also carry brands like Simonton and PGT, which means we’re not trying to sell you whatever’s on the truck. We order what your home actually needs.

Door Installation
Exterior doors in Westlake Village carry the same dual burden as windows: fire rating plus HOA aesthetics. A front door with a combustible frame or non-rated glass can fail inspection on a VHFHSZ-listed home, and a door color that didn’t clear the architectural committee can trigger a stop-work order. We handle both approvals. From solid-core entry doors to fiberglass and fire-rated units, we install materials that pass the city and satisfy the HOA, and the price is fixed in writing before we order.

Custom Windows & Doors
Westlake Village has a lot of high-end estates on graded hillside lots, and those homes don’t want off-the-shelf anything. Custom windows and doors here mean architectural glass, specialty finishes, and long lead times. The lead time is the calendar. A custom glass package for a hillside estate off Lindero Canyon Road can run fourteen weeks before it lands in our shop. Here’s what matters: we lock the price in writing before the first deposit is drawn, so the wait doesn’t come with a surprise invoice at the end. Westlake Village homeowners who have been burned by other contractors tell us that’s the difference.

Common Windows & Doors Problems We See in Westlake Village Homes
- Charcazel 7A conflicts with HOA aesthetics. Certain fire-rated vent covers and frame materials that satisfy the city don’t match the HOA’s approved palette. We’ve seen a homeowner buy a non-conforming fire vent and lose weeks to a stop-work order. We run both approvals before you buy.
- Dry rot behind the stucco. A $4,500 window replacement can turn into a structural repair when the original wood framing has been quietly rotting for decades. We check the rough opening, show you what’s there, and give you a written change order before any load-bearing work starts.
- Original aluminum sliders gone bad. Forty-plus years of valley heat and Santa Ana wind leaves old aluminum frames warped, pitted, and leaking conditioned air. The west-facing walls of Westlake Village homes cook every afternoon, and those old sliders are the weak point.
- Permit surprises. Some contractors tell homeowners permits are optional. In Westlake Village, they aren’t. Chapter 7A applies on exterior work, and the inspector will check. If the last contractor told you otherwise, call us for a free second opinion on any written estimate.

FAQs - Windows & Doors in Westlake Village
Yes. Because Westlake Village sits in a Very High Fire Hazard Severity Zone, exterior window and door work must comply with California Building Code Chapter 7A, and the permit inspection will check. Separately, most Westlake Village HOAs require architectural committee approval before you change exterior materials, colors, or styles. We run both approvals before ordering materials, so you never buy something you can’t install. Call (877) 610-1318 to start with a free estimate.
Because custom and fire-rated glass has a longer production queue. A standard double-hung might arrive in three weeks; a fire-rated, dual-pane custom unit for a hillside estate can run fourteen weeks. It’s the glass, not our labor, that sets the schedule. We lock your price in writing before the first deposit, so the wait never turns into a surprise invoice. Call (877) 610-1318 and we’ll map the whole timeline for you.
Not always. Westlake Village HOAs often restrict frame colors and sometimes materials. A fire-rated vent cover that satisfies the city may not match the HOA’s approved palette. We submit your selection to the architectural committee before ordering so there’s no stop-work order and no costly change order mid-project. Call (877) 610-1318 to start with a free estimate and we’ll review your HOA’s standards with you.
For existing homes, full impact glazing isn’t always mandatory on every opening, but any new window or door on an exterior wall in a VHFHSZ home must meet Chapter 7A fire-hardening standards, which often includes fire-rated glass and ember-resistant framing. Home Additions & ADU in Westlake Village and significant remodels trigger stricter requirements. Don’t guess. We’ll look at your specific lot, your exposure, and your HOA’s rules, then tell you exactly what the city will enforce. Call (877) 610-1318 for a free estimate.
Every scope, every allowance, every price change in writing before work happens. The permit obligation stated plainly. The HOA architectural approval timeline spelled out. The brand and model of every window and door, not just a category. The lead time for custom glass. The 90-Day Done Right Promise, on paper, not in fine print. If your contract doesn’t include those, call (877) 610-1318 and ask for a free second opinion on any written estimate.
