Window and door replacement in Calabasas runs $180 – $1,200 per opening depending on the product, with most full-home projects landing between $8,500 and $22,000. Every job here carries a mandatory Wildland-Urban Interface compliance layer that flatland contractors rarely handle. Call us at (562) 478-8017 for a written estimate before any work starts.
Calabasas homes aren’t like the tract houses in the San Fernando Valley. The custom Mediterranean and Tuscan Revival builds from the 1990s and 2000s have arched openings, oversized pivot doors, and non-standard sizes that make off-the-shelf replacements impossible. The Santa Ana winds tearing down the Las Virgenes corridor degrade seals and warp frames years faster than they do in Burbank or Van Nuys. And the Very High Fire Hazard Severity Zone designation means Chapter 7A compliance isn’t optional, it’s code. We carry the eight manufacturer brands that actually make products rated for these conditions, and we know the dual-permit track that gated communities here require.
Why Calabasas Homes Are Different
The Woolsey Fire in 2018 burned straight through the adjacent hillsides, and that memory is still fresh when homeowners replace windows or doors. Chapter 7A of the California Building Code requires multi-pane tempered or heat-strengthened glass and ignition-resistant frames for any exterior opening in Calabasas. A contractor who doesn’t build this into the quote from day one will hit you with change orders when the inspector flags it, or worse, install non-compliant products that void your homeowner’s insurance.
The wind is the other factor that shapes every recommendation. Santa Ana gusts exceeding 60 mph drive hot, desiccating air against homes in the foothills, accelerating weatherstripping failure and forcing premature seal breakdown. Dual-pane low-E glazing with warm-edge spacers isn’t a luxury here; it’s what keeps your HVAC from running flat-out in August and what insurers increasingly document for fire-mitigation discounts.
Then there’s the HOA layer. In The Oaks at Calabasas and The Peaks, exterior modifications need architectural committee approval before the county will even see your permit. The committee meets monthly. Submit both applications simultaneously, or watch your project slip six weeks while the crew sits idle. We’ve watched out-of-area companies learn this the hard way.
Our Main Calabasas Services
Most Calabasas homeowners call us for one of three jobs. Each has its own page with full pricing, brand options, and local compliance details.
Window Replacement in Calabasas
We remove existing windows and install new units rated for Chapter 7A, with dual-pane low-E glass and ignition-resistant framing. In Calabasas, this almost always means custom sizing for arched or oversized openings from the 1990s – 2000s builds. We handle the LA County permit and, when needed, coordinate parallel HOA submission for gated communities. Our crews work with shoe covers and drop cloths on every visit, and we photograph the clean-up before we leave. Window Replacement in Calabasas has full pricing and brand options.
Window Installation in Calabasas
New-construction window installation in Calabasas typically involves hillside builds with structural framing challenges and exposed orientations that demand higher wind-load ratings than standard products offer. We spec CGI or CWS units with the DP ratings to match Santa Ana exposure, and we flash every opening to the Chapter 7A ignition-resistant standard. The written price covers full rough-opening prep, permit pulling, and inspection coordination. Window Installation in Calabasas has the complete breakdown.
Door Installation in Calabasas
Oversized pivot doors, French door systems, and multi-slide patio doors are standard in Calabasas custom homes, and they require precise structural support and weathersealing against wind-driven ember intrusion. We install Therma-Tru and ES Windows entry systems rated for WUI compliance, with proper sill pan flashing and tempered glass where code requires. HOA architectural review often applies, and we build that timeline into every quote. Door Installation in Calabasas covers brands and lead times.

- Andre Bellamy"They replaced a big foggy picture window. Careful with the furniture, laid down protection, and left no mess at all. Calm and respectful crew, and the view is clear again."
