AfterFast, Reliable Window Replacement Across Calabasas
Window replacement in Calabasas is not a pick-a-number job. Most homes here were built between the late 1970s and mid-1980s with original aluminum single-pane windows, and those units now fail two codes at once: California Title 24 energy standards and Los Angeles County’s Very High Fire Hazard Severity Zone requirements. A full-frame replacement on a typical Calabasas tract home runs $900-$1,800 per opening, while insert replacements run $550-$1,100 per opening, depending on glass spec and frame material. Call (888) 635-0804 and we’ll give you a written line-item quote before any work begins.
We’re TruePane Windows & Doors, and we’ve worked Calabasas long enough to know its hillside streets, its HOA rulebooks, and its inspectors. When you call, a live person answers. Not a voicemail tree. Not a callback form. The same steady voice every time.
Why TruePane Windows & Doors Is Calabasas’s Preferred Window Replacement Company
Calabasas homeowners keep our number because we show up when we say, we measure twice, and we put our warranty in writing before the truck leaves the driveway. Dale Kessler founded this company in 2008 on a simple rule: if the pane is not true, the job is not done. That rule governs every Window Replacement we install, from a single fogged insert in Calabasas Park to a full hillside retrofit above Mulholland Highway.
We’re not the cheapest bid in Calabasas, and we don’t try to be. Cheap bids here usually mean glass that fails VHFHZ inspection or vinyl that warps under Santa Ana heat. What we offer is a square deal: upfront pricing, both manufacturer warranty layers registered in writing, and a Done Right Promise that means something. If the work isn’t done right, we make it right. No paperwork fights. No fine print.
Our crews are background-checked and uniformed. They stage carefully on tight Calabasas lots, keep dust and debris contained, and respect HOA work-hour rules without being asked. We’ve replaced windows in The Oaks, Calabasas Hills, and gated communities off Las Virgenes Road. We know the architectural review process in each one.
Our Window Replacement Services in Calabasas
Full Frame Replacement
Full-frame replacement means the old window, frame, and trim come out to the rough opening. In Calabasas this is often the only path when the original 1970s aluminum frame has corroded, lost its thermal break, or no longer supports compliant glass. We rebuild the opening with new flashing, new jamb extensions, and a frame that meets both Title 24 and VHFHZ standards. A full-frame replacement in Calabasas typically runs $900-$1,800 per opening for double-pane, low-E, tempered units.
Insert Window Replacement
If the existing frame is square and sound, we can set a new insert window inside it. This is the most common route for Calabasas tract homes where the stucco is intact and the homeowner wants to avoid disturbing exterior finishes. Inserts go in faster and cost less, typically $550-$1,100 per opening. The catch is that an insert only passes Calabasas inspection if the glass itself meets current fire-hardening and energy requirements, which many big-box off-the-shelf units do not.
Storm Window Replacement
Santa Ana winds push hard through the passes near Calabasas, and older storm windows on 1980s homes are often bent, cloudy, or missing weatherstripping by now. We replace exterior storm windows with new aluminum or vinyl units that cut wind noise, reduce drafts, and add a second boundary against ember intrusion during red-flag days. Storm window replacement in Calabasas runs $300-$700 per window installed.
Energy-Efficient Upgrade
Summer temperatures in Calabasas regularly run 10-15 degrees hotter than coastal LA, and south- and west-facing walls take the worst of it. Upgrading to low-E, argon-filled, dual-pane units cuts that heat load and drops PG&E costs measurably. We quote side by side on paper, manufacturer against manufacturer, so you see exactly what the glass coating, gas fill, and frame material cost. Energy-efficient upgrades here run $700-$1,500 per opening depending on glass package and frame choice.

Trusted Brands We Service in Calabasas
TruePane is an authorized installer for more than a dozen manufacturer lines, including, PGT, and CGI. For Calabasas jobs we often spec PGT and CGI impact-rated lines because their multi-pane tempered glass and ignition-resistant frames clear VHFHZ inspection without argument. We also carry Ply Gem for homeowners who want a solid mid-range option. Because we order directly and register both warranty layers in writing, Calabasas customers skip the supply-chain delay that plagues big-box orders.
Common Window Replacement Problems We See in Calabasas Homes
- Off-the-shelf vinyl with non-tempered glass fails inspection. A homeowner buys windows at a big-box store, gets them installed, and then the city inspector flags the glass because it does not meet Calabasas VHFHZ fire-hardening standards. The fix means pulling the windows and starting over. We quote compliant glass from the first conversation.
- HOA architectural review stalls the job midway. In communities like The Oaks, a general contractor starts pulling windows before the review committee signs off. The city stops the permit, the opening sits exposed for weeks, and the homeowner eats the delay. We submit product cut sheets, frame color samples, and grid pattern drawings before we ever schedule a truck.
- Santa Ana pressure differentials kill dual-pane seals. The northeast wind corridor through the Santa Monica Mountains creates sustained pressure stress on window seals. We see fogged panes on 15-year-old windows that should have lasted twice that. Replacement glass for these units must still meet Calabasas fire code, not just match the original spec.
- Narrow hillside streets turn staging into a code-enforcement problem. A crew parks a box truck across a neighbor’s driveway on a tight cul-de-sac, and the city gets a complaint before the first pane is set. We stage from the homeowner’s driveway, use sealed debris bags, and keep noise inside HOA hours.

FAQs - Window Replacement in Calabasas
Full-frame replacements always require a city permit in Calabasas, and so does any replacement that changes the glass type or frame material. A straightforward insert with identical glass and frame sometimes does not, but because Calabasas sits inside the Very High Fire Hazard Severity Zone, most replacement glass must be upgraded to multi-pane tempered units, which triggers a permit anyway. We pull permits, pass inspections, and handle the paperwork. Call (888) 635-0804 and we’ll tell you exactly what your job needs.
Most Calabasas HOAs, including The Oaks, require product cut sheets, frame color samples, and grid or muntin pattern drawings before they’ll sign an architectural review application. The review alone adds 3 to 6 weeks to the timeline. We prepare the package, submit it, and track the approval so the city permit isn’t held up. Homeowners who skip this step end up with an open window opening and a code enforcement letter. Call (888) 635-0804 and we’ll start the review process with you.
Yes, fogging between panes is a dual-pane seal failure. It means the insulating gas has escaped and moisture has entered the air space. In Calabasas it matters for fire code because a failed seal means the window no longer performs as a rated assembly, and any replacement glass must meet current VHFHZ standards, not just match what was there before. We’ll spec compliant replacement glass and register the warranty in writing. Call (888) 635-0804 for an exact quote.
We stage from the homeowner’s driveway, not the street. All sash, jamb, and glass debris goes into sealed bags before it leaves the opening. Crews park single-file, never block a neighbor’s driveway, and finish loud work before the HOA’s noise cutoff. On a recent job in The Oaks, we kept a full replacement moving on a postage-stamp lot with a shared property line without a single neighbor complaint and had the architectural review committee’s pre-approved frame color in hand when we pulled up. Call (888) 635-0804 and tell us about your lot; we’ll build access into the quote.
Yes. Calabasas sits inside Los Angeles County’s Very High Fire Hazard Severity Zone as a city, not just on the hillside. The 2018 Woolsey Fire burned directly through surrounding neighborhoods, and the fire-hardening code applies to most residential replacement glass throughout the 91302 ZIP. That means multi-pane tempered glass, ignition-resistant or non-combustible frames, and ember-resistant flashing details, even on flat lots. We quote compliant glass from the first conversation. Call (888) 635-0804 for a written estimate.
If you’re replacing windows in Calabasas, start with a company that knows the VHFHZ code, the HOA review process, and the tight-lot access rules cold. Call (888) 635-0804 and ask for a free estimate. We’ll come out, measure every opening twice, and put the numbers on paper. Done right, in writing, before any work starts.
