Why Malibu Homes Are Different
Malibu sits in a regulatory position that almost no other U.S. city shares: the entire municipality is both a California Coastal Zone and a state-designated Very High Fire Hazard Severity Zone. That means every replacement window and door must satisfy two extreme demands at once. The Pacific side needs marine-grade, anodized aluminum or fiberglass frames that won’t corrode from salt air within three to five years, while the canyon-facing elevations need Chapter 7A WUI-rated, multi-pane tempered assemblies with non-combustible or ignition-resistant frames to pass post-Woolsey Fire permit inspections.
The housing stock reflects this tension. Roughly 13,000 residences range from 1950s beachfront bungalows and stilted PCH cottages with original single-pane aluminum sliders to post-2018 luxury rebuilds constructed entirely to current WUI standards. In Serra Retreat and along Malibu Road, we regularly find hollow-core wood doors and single-pane windows that fail both current fire code and Title 24 energy standards, making full-code upgrades the only legal path forward. Santa Ana winds funneling through Malibu Creek, Topanga, and Las Virgenes canyons add extreme positive pressure and live firebrand exposure that standard assemblies simply aren’t engineered to handle.
Our Main Malibu Services
Malibu homeowners call us most often for two types of jobs: replacing failed or code-noncompliant existing units, and installing new openings in additions or rebuilds. Each service has its own Malibu page with detailed pricing and process information.
Window Replacement in Malibu
Window replacement in Malibu almost always involves a code upgrade, not a simple like-for-like swap. The older stock in neighborhoods like Serra Retreat typically has single-pane aluminum sliders that fail current WUI and energy standards, so we specify dual-pane tempered glass with non-combustible or ignition-resistant frames and ember-resistant screening. On ocean-facing walls, we shift to marine-rated anodized aluminum or fiberglass to prevent the salt-air corrosion that seizes standard tracks within a few seasons. We pull all permits, pass all inspections, and put the written price in front of you before any work starts. Window Replacement in Malibu

Window Installation in Malibu
New window installation in Malibu usually happens in post-Woolsey rebuilds, second-story additions, or conversions of garage or basement space. These jobs require fresh rough openings, structural headers, and full Chapter 7A compliance from day one. We coordinate with your architect or builder on frame specs, flashing details, and egress requirements, and we stock marine-grade hardware from brands like CGI and ES Windows for the salt-air elevations. Our crews work with drop cloths and shoe covers, and we photograph the clean-up before we leave. Window Installation in Malibu

Door Installation in Malibu
Door installation in Malibu covers entry systems, patio sliders, and French doors, each with its own compliance path. Entry doors need ember-resistant assemblies with non-combustible thresholds and jambs for WUI zones, while patio doors facing the ocean need marine-grade tracks and corrosion-resistant hardware that won’t bind after two seasons of salt spray. We carry Therma-Tru and ViewLux for entry systems and can source multi-slide or lift-and-slide hardware for the larger openings common in newer construction. Every door gets a written price before we start. Door Installation in Malibu

FAQs About Window Company in Malibu
Yes. The city requires permits for all window and door replacements, and most projects trigger Chapter 7A WUI compliance review. We pull the permit, submit the product cut sheets, and schedule the inspection as part of every job. Call (562) 478-8017 and we’ll walk through whether your specific property needs a full code upgrade or qualifies for a repair exemption.
Many Malibu neighborhoods, including parts of Serra Retreat and the Colony, have design review boards or HOA architectural committees. We provide full product submittal packages with finish samples, frame profiles, and installation details to speed approval. Call (562) 478-8017 and we can review your CC&Rs before the estimate.
PCH closures, canyon fire weather, and gated community access can all affect timing. We confirm entry codes or guard gate protocols before the crew departs, and we reschedule at no charge if Caltrans or fire conditions block access. A live person answers our phone 24/7, so you never reach voicemail when conditions change.

What Malibu Customers Say
"Replaced six windows. The crew laid runners through the house and vacuumed each room as they finished. With a crawling baby, that no mess thing meant a lot. Windows are gorgeous."
- Rosalind Kemp"Lovely windows and a tidy install. One window came in a couple weeks late from the factory, so that opening finished after the others. They kept me posted and the rest was spotless."
- Mia Donnelly"Quiet, considerate install of several windows. They cleaned the glass and the sills and vacuumed every room. You'd never know a crew had been through. House is quieter and brighter."
- Brent Sakamoto
