Why Barrett & Sons Construction Is Westlake Village’s Preferred Windows & Doors Company
Westlake Village is a place where the same houses were built within a twenty-year window, so when we pull a 1970s slider out of a wall on Lindero Canyon Road, we already know what’s behind it. The framing is predictable. The stucco is original. The rough opening is rarely square. That’s not a problem; it’s just what the job is. More useful is that we know how the HOA architectural committees in the First Neighborhood and Three Springs operate, and we know how to sequence their approval with the fire marshal’s sign-off so your windows don’t sit in a warehouse while two boards argue about vent covers.
Our reputation in Westlake Village is built on written change orders and permits pulled on every job. No surprises. No “we discovered rot, here’s a new number” phone call. If a scope change comes up, you get it in writing before a nail moves. That’s how Tom Barrett has run this company since 1998, and it’s why the L.O.C.A.L. values code we work under starts with Local roots and Accountable. Ask anyone on your street, or look up the license number yourself. Tom publishes his name, his address, and his license number, and he lives close enough to care what your house looks like when the job is done.
Our Windows & Doors Services in Westlake Village
Our Windows & Doors team handles the full scope of replacement and new-installation work in Westlake Village. Here’s how the most common jobs break down.
Window Installation
Most window installations in Westlake Village are replacements in homes built between 1968 and 1985, which means we’re working with wood framing that predates Title 24 energy standards and stucco that has to be cut back cleanly for proper flashing. We pull the permit, order the units to the HOA-approved profile, and schedule the inspection. If the house is in the VHFHSZ, and most of Westlake Village is, the glass specification is different from what a big-box store will sell you off the shelf. We order to code, not to what’s cheap.

Door Installation
Entry doors in Westlake Village take a beating from Santa Ana winds funnelling off the ridgelines. A properly hung door here isn’t just level and plumb; it’s sealed against wind-driven dust and set so the deadbolt throws clean under load. We install wood, fiberglass, and steel entry doors, and we coordinate hardware selection with the architectural style the HOA has on file for your tract or custom lot.

Window Replacement
A typical window replacement project in Westlake Village runs $4,500 to $15,000 for a whole home. The range depends on how many windows, whether you’re in a single-story tract home or a two-story custom on a hillside, and whether the HOA requires a specific frame material or color. We quote every line item in writing, and the price doesn’t move unless you sign a change order.

Impact Windows & Doors
Impact windows and doors in Westlake Village are a practical decision, not a coastal luxury. The VHFHSZ designation means ember intrusion is a real risk during Santa Ana events, and the 2018 Woolsey Fire burned to the community’s doorstep. We install impact-rated glass from PGT and CGI, specified for Chapter 7A compliance, with the stainless steel mesh vent covers that fire code requires. Before we order, we check the HOA’s approved materials list so the first submittal has a real shot at approval.

Trusted Brands We Service in Westlake Village
We install Simonton, Ply Gem, and PGT windows and doors, and we carry parts for local service calls so we’re not waiting on a distributor in Van Nuys for a replacement roller or latch. When a Westlake Village customer calls about a failed balance on a Simonton double-hung, we can usually have it running right the same week. For impact work, PGT and CGI units are ordered directly to the size and finish the HOA approves. If the hardware your designer specified is backordered from Emtek or Schlage, we’ll tell you before you sign anything, and we’ll write the allowance so the price is fixed on paper, not discovered later.
Common Windows & Doors Problems We See in Westlake Village Homes
- HOA denial of fire-rated vent covers. The architecture committees in Westlake Village often reject standard Chapter 7A mesh vent covers as visually non-conforming. We’ve solved this repeatedly by pulling samples and walking the committee through the fire code rationale before ordering a single unit.
- Custom orders placed before HOA sign-off. A homeowner orders a custom door with a specific frame profile, gets the HOA’s approval on style, and discovers the approved profile doesn’t match what’s on order. That’s a change order and weeks of added lead time. We sequence the approvals first, then order.
- Title 24 failures on off-the-shelf units. Westlake Village homes built before energy mandates often have non-standard rough openings and post-tension slabs. A door or window from a big-box store can fail final inspection because the rough-in doesn’t match what the unit was designed for. We measure, then order to fit what’s actually there.
- Aluminum frames from the 1970s failing at the corners. The original aluminum sliders in Westlake Village’s early tracts are hitting fifty years old. The corners loosen, the frames rack, and the glass rattles every time the Santa Anas kick up. We see this in nearly every home we touch, and it’s a replacement job, not a repair.

HOA-required wood species or custom colors add to the order. And if the home sits in the VHFHSZ, which covers most of the city, every opening has to meet Chapter 7A.

FAQs - Windows & Doors in Westlake Village
Because nearly every home in the city falls under two jurisdictions: the city’s building department, which enforces California Building Code Chapter 7A fire-resistant standards due to Westlake Village’s location within a Very High Fire Hazard Severity Zone, and an HOA architectural committee that controls exterior appearance. One approval isn’t enough; you need both before an order goes to the manufacturer, or you risk paying for custom units that one board or the other will reject. We sequence the HOA submittal and the permit application in parallel so a single window doesn’t sit in our shop for three weeks. Call (877) 610-1318 and we’ll walk you through the timeline for your specific tract or custom lot.
We order the door only after the HOA architectural committee has signed off in writing on the species, the profile, and the finish. If the specified wood is a long-lead item, we tell you the honest timeline before you sign a contract. Some specialty wood doors run ten to fourteen weeks from order to delivery, and that’s the calendar regardless of who hangs it. We fix the price in writing before ordering, so a supplier’s price change doesn’t become your problem. Call (877) 610-1318 for a line-item quote that shows the actual lead time.
Yes, when the door is hung correctly and the hardware is specified for the exposure. An entry door on the windward side of a hillside lot in Westlake Village takes a much harder gust load than the same door in Thousand Oaks proper. We specify Schlage or Emtek hardware with a heavy-duty deadbolt throw and a reinforced strike plate, and we set the door so the latching hardware engages fully under wind pressure. A cheap deadbolt in a bowed frame will rattle and eventually fail, so we don’t install one. Call (877) 610-1318 and we’ll check your existing door’s wind seal while we’re there.
The answer depends on your specific HOA’s architectural guidelines, which vary by neighborhood. In our experience, fiber-cement trim and certain dual-glazed impact units with stainless steel mesh vent covers are acceptable to most committees once the fire code rationale is explained in person. On a custom hillside home in Three Springs, we replaced 1979 aluminum sliders with dual-glazed, low-E Milgard units specified for Chapter 7A, and the architectural committee initially flagged the required 1/16-inch stainless steel mesh vent covers as visually inconsistent. Our crew pulled samples, walked the committee through the fire code, and got approval that same week. The key is submitting the right materials the first time. We do that as standard practice. Call (877) 610-1318 to get the process started.
Yes, we do. Glass railing systems on decks overlooking Westlake Village’s open space corridors have to meet both structural loading requirements and the HOA’s aesthetic review, and designers often specify glass from suppliers with long lead times. We coordinate directly with your designer or architect, and we write the allowance so a hardware backorder or a specialty glass delay from a European supplier doesn’t hit your wallet as an overage. The price is fixed on paper before anyone orders a single panel. Call (877) 610-1318 to schedule a free estimate with our Windows & Doors team.
