Window Installation in Calabasas: What It Costs and How HOA Review Affects the Timeline
Window installation in Calabasas typically runs $800-$2,400 per opening for standard retrofit work, and $1,500-$4,500 per opening when full frame replacement with WUI-compliant tempered glass and ignition-resistant frames is required. Most Calabasas jobs take 2-5 days of on-site work, but the architectural review committee step in communities like The Oaks and Calabasas Park Estates adds 3-6 weeks before a city permit can be pulled. If you’re planning replacement windows in Calabasas, start the HOA submittal now, not after the windows are ordered. Call (888) 635-0804 and we’ll walk you through the sequence from committee sign-off to final inspection.

Calabasas Window Installation Is Different From the Rest of the Valley
We get calls from Calabasas homeowners who already replaced windows once and failed inspection, or who tore out a wall of glass only to have the HOA send a stop-work notice. Calabasas is not Woodland Hills. The city sits inside the Woolsey Fire burn scar and Los Angeles County’s Very High Fire Hazard Severity Zone, so every exterior window replacement must meet wildland-urban interface standards: multi-pane tempered glass, ignition-resistant or non-combustible frames, and ember-resistant construction details that are not required in neighboring Woodland Hills or Agoura Hills. A window that passes in Canoga Park will get rejected in Calabasas.
Then there’s the HOA layer. In The Oaks at Calabasas and Calabasas Park Estates, every exterior window or door replacement requires architectural review committee sign-off before the city will even look at a permit. Contractors who don’t know this put non-conforming windows in and get forced to tear them out. We’ve been through it enough times to know exactly what the committee wants to see, and we file the packet ourselves.
TruePane Windows & Doors is led by Dale Kessler, a second-generation glazier who started this company in 2008 on a simple rule: if the pane is not true, the job is not done. Our Window Installation team has spent years working Calabasas, from the 1980s tract homes off Mulholland Highway to the gated luxury communities above Las Virgenes Road. Dispatch is coordinated from our Los Angeles office, but the crews on your job live and work locally. A live person answers at (888) 635-0804, 24 hours a day. Not a voicemail tree. Not a callback form.
Why TruePane Windows & Doors Is Calabasas’s Preferred Window Installation Company
Calabasas homeowners ask the same questions every time: Can you get the HOA packet right the first time? Will the windows pass WUI inspection? Will you still answer the phone in five years if a seal fails? We answer yes, yes, and yes, and we put it in writing.
We register both manufacturer warranty layers in writing before the truck leaves your driveway. That’s The Keystone Standard. If something is not done right within 90 days, we make it right. No paperwork fight. No arguing. We also employ background-checked, uniformed technicians who measure every opening twice and quote manufacturer lines side by side on paper, so you see exactly what you’re buying before you sign.
We’re an authorized installer for more than a dozen manufacturer lines, including, PGT, CGI, and ES Windows. In Calabasas, we lean heavily on PGT, CGI, and Ply Gem because those lines carry the WUI-rated products this city’s building department requires. We don’t sell you a brand we wouldn’t install in our own homes.
Our Window Installation Services in Calabasas
Calabasas housing skews two directions: late-1970s to mid-1980s tract homes with original aluminum single-panes, and 1990s-2000s luxury homes with wood-clad and aluminum-clad premium systems. We handle both, and everything in between. Here’s what we install most often across the 91302 ZIP code.
Casement Windows
Casement windows are the most common upgrade for those 1980s Calabasas tract homes because they seal tight on all four sides and hold up against the Santa Ana wind pressure differentials that roll through the Santa Monica Mountains passes. We install casements with multi-point locking hardware and tempered, WUI-compliant glass. In Calabasas, casement windows typically run $900-$2,200 per opening for full replacement.

Fixed & Picture Windows
Homes along Mulholland Highway and in the hillside communities above Las Virgenes Road lean hard on fixed and picture windows for the ridgeline views. These are the windows that fail WUI inspection quickest when spec’d wrong: a big fixed pane facing the wildland edge must be tempered, must use an ignition-resistant frame, and must be set square. We stock and install PGT and CGI picture windows rated for the VHFHZ. Expect $800-$2,400 per opening in Calabasas, depending on glass package and frame material.

Single & Double Hung Windows
Double-hungs are the workhorse of the Calabasas tract home, but cheap ones fail fast. We see fogged panes and lost argon within five years on original 1980s double-hungs because the Santa Ana pressure differentials stress the seals. We install double-hungs rated for high wind zones, with extruded frames and balanced sashes that don’t sag. In Calabasas, double-hung replacement runs $700-$1,800 per opening for standard retrofits, more when the rough opening needs reframing.

Sliding Windows
Sliding windows show up on Calabasas mid-century lots and ranch-style homes in the flats. The failure mode is usually in the track: warped aluminum from decades of summer heat. We replace sliders with reinforced tracks and rollers that handle the thermal expansion. Prices in Calabasas typically land between $750 and $1,900 per opening.

Common Window Installation Problems We See in Calabasas Homes
- Skipping the HOA architectural review committee step. Homeowners put in non-conforming windows and are forced to tear them out. The standard 3-6 week review calendar catches every contractor who doesn’t know The Oaks or Calabasas Park Estates rules. We file the packet before we order the windows.
- Windows spec’d for coastal LA fail Calabasas WUI inspection. Standard dual-pane glass and vinyl frames that would pass in Valley suburbs get rejected here. The Calabasas building department requires tempered, ignition-resistant products. We quote accordingly from day one.
- Santa Ana wind pressure kills cheap seals. The northeast wind corridor through the Santa Monica Mountains passes creates sustained pressure differentials that accelerate dual-pane seal failure. We see fogged panes and lost argon on windows less than five years old when the original install used budget double-hungs.
- Thermal stress on south and west-facing frames. Calabasas summer daytime temperatures run 10-15°F above coastal LA. Dark frames on south and west elevations absorb that heat and warp. We recommend lighter frame colors and thermally broken frames in these exposures.
What Gets Approved in Calabasas (And What Doesn’t)
If you live in The Oaks at Calabasas or Calabasas Park Estates, your architectural review committee wants to see three things in the submittal packet: product cut sheets for the exact window you’re ordering, frame color samples that match the community’s approved palette, and grid or muntin pattern drawings that match neighboring homes. They don’t want to see a bid sheet from a contractor who hasn’t read the CC&Rs.
In The Oaks at Calabasas, our crew replaced a wall of failing aluminum single-panes with Marvin Ultimate wood-clad casement windows, but not before we filed the architectural review packet with cut sheets, frame color samples, and grid pattern drawings. The HOA review added four weeks, so we staged the order and scheduled demolition to begin only after committee sign-off. No half-finished openings, no failed inspection. That’s how you do it in this city.
We file the packet. We track the committee calendar. We order the windows to arrive the week approvals clear. Then we build the full permit set for the city, pull the permit, and schedule the work so windows come out and new ones go in the same day. You’re never living with a boarded-up opening waiting on a review board.

FAQs - Window Installation in Calabasas
No. Only homes inside HOA-governed communities like The Oaks at Calabasas and Calabasas Park Estates require committee sign-off. If your home sits outside an HOA, we go straight to the city permit step. To know for sure, pull your CC&Rs or call us at (888) 635-0804 and we’ll check your address against the association map.
Calabasas sits inside Los Angeles County’s Very High Fire Hazard Severity Zone, a designation most Valley suburbs don’t carry. The 2018 Woolsey Fire burned directly through the hills surrounding this city, so the building code requires multi-pane tempered glass, ignition-resistant or non-combustible frames, and ember-resistant details on all exterior window replacements. Woodland Hills has different exposure maps and different requirements. We quote to Calabasas code every time, because we know the inspector will check.
Santa Ana winds funnel aggressively through the Santa Monica Mountains passes near Calabasas, creating sustained pressure differentials that stress window seals and hardware. For double-hungs, that means we specify reinforced frames, higher-grade weatherstripping, and balanced sashes that don’t rattle or bind when the wind shifts. Cheap double-hungs installed in this corridor fog up fast. A properly spec’d double-hung handles it fine. Call (888) 635-0804 for a detailed quote on wind-rated double-hungs.
It depends on the condition of the rough opening and the existing frame material. Most 1980s Calabasas tract homes have aluminum frames that are not ignition-resistant, so retrofitting sashes alone won’t pass WUI inspection. Full frame replacement with a non-combustible or ignition-resistant frame is usually required. In some cases, we can reuse the opening with a direct-set window and skip the new frame. We’ll tell you which path applies to your house after we measure. Estimates are free.
Start 3-6 weeks before you want work to begin. The review committee in The Oaks typically takes that long to review product cut sheets, frame color samples, and grid pattern drawings. We recommend starting the packet the moment you know you’re going to replace windows. We file the submittal for you, track the meeting date, and stage the window order so everything arrives the week approvals clear. Call (888) 635-0804 and we’ll map out the whole calendar so you’re not living with half-finished openings.
Window Installation in Calabasas Should Not Feel Like a Gamble
You’ve lived in this house for twenty years. You plan to stay. You don’t want a contractor who shows up once, slaps in a window that fogs in four years, and stops answering the phone. Call TruePane Windows & Doors at (888) 635-0804. We’ll come measure, quote the manufacturers side by side on paper, file whatever HOA packet your community requires, and install windows that pass Calabasas inspection the first time. Dale Kessler founded this company on a rule that hasn’t changed in years of glazing: if the pane is not true, the job is not done.
