AfterFast, Reliable Custom Windows & Doors Across Los Angeles
Custom windows and doors in Los Angeles are rarely a simple swap. The city’s housing stock runs heavily to 1920s and 1930s stucco bungalows and Spanish Colonial Revival homes, and those houses were built with steel casements, arched rough openings, and framing practices that don’t line up with modern off-the-shelf products. We measure every opening twice, quote manufacturer lines side by side on paper, and write allowances into the contract for what might be hiding behind the stucco before the first wall is opened. If you’re in Los Angeles and the windows are original or the door binds in July, call (888) 635-0804 for a free estimate. We do the work the way we’d do it in our own mother’s house.
Why TruePane Windows & Doors Is Los Angeles’s Preferred Custom Windows & Doors Company
We’ve been at this long enough to know what Los Angeles walls actually hide. Dale Kessler founded TruePane in 2008 after years of watching out-of-true installs and voided warranties become someone else’s expensive problem. The whiteboard in our shop still reads: if the pane is not true, the job is not done. That rule governs every opening we touch in Los Angeles, from the smallest bungalow in 90001 to a hillside home in Brentwood.
Our crews are background-checked, uniformed, and trained as apprentices into journeymen. We hire local and we plan to be in Los Angeles in thirty years. That’s not a slogan. We sponsor county fairs and church roof funds here because our reputation walks the same streets our customers do. Every job is covered by the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves your driveway. A live person answers the phone 24 hours a day, 7 days a week. Not a voicemail tree. Not a callback form. Call (888) 635-0804 and you’ll talk to a person who can answer questions about Los Angeles window code and schedule your free estimate.
Our Custom Windows & Doors Services in Los Angeles
Custom Shape Windows
Arched, radius, and cathedral openings are standard fare in Los Angeles’s Spanish Colonial Revival and Craftsman homes, and they demand more than a standard rectangle dropped into a framed hole. We pattern every curve, order the glazing to match the exact radius, and set the unit so the stucco reintegration looks original. In neighborhoods throughout Los Angeles with 1930s construction, we routinely replace original single-pane steel casements set into decoratively shaped rough openings with custom-sized units that meet current Title 24 requirements.
Architectural Grilles & SDLs
Homeowners in Los Angeles who bought a 1920s Craftsman didn’t buy it to make it look like a tract house. Simulated divided lites and architectural grilles preserve the divided-lite look while the insulated glass unit behind them does the real energy work. We quote SDL patterns side by side with true divided lite options on paper, so you can see the difference in both appearance and cost before you commit. The goal is a window that looks like it belongs in a Los Angeles bungalow and performs like a modern unit.
Oversized Glass Panels
Floor-to-ceiling glass, picture windows, and sliding door walls are popular in Los Angeles renovations that open the back of the house to a patio or a view. These panels are heavy, and they don’t forgive sloppy flashing or a soft rough opening. Our crews reinforce framing where needed, set the panel true, and detail the waterproofing so the first winter rain doesn’t find a gap. We’ve handled panels large enough that they required a crane, and panels small enough to carry through a courtyard apartment gate in 90001. The process is the same: measure twice, set true, flash properly, stand behind it.
Commercial Storefront Glazing
Los Angeles storefronts take a beating: sun, smog, and the occasional shopping cart. We replace and service commercial storefront glazing for small property owners and retail businesses throughout Los Angeles, including curtain wall systems for mid-rise retrofit projects. Work is scheduled around business hours when it matters, and every commercial job gets the same written warranty registration as our residential work. If you own a storefront in Los Angeles and the glass is cracked or the frame is pulling away from the stucco, call (888) 635-0804.

Trusted Brands We Service in Los Angeles
TruePane is an authorized installer for more than a dozen manufacturer lines, including PGT, CGI, and ES Windows, and we service and install products from. That matters in Los Angeles because Title 24 Climate Zone 9 and 10 requirements disqualify some national product lines on paper, and we can tell you which ones before you spend money on a product that won’t pass LADBS inspection. We keep commonly needed parts and hardware in Los Angeles for faster turnaround on service calls, and we can quote multiple manufacturer lines side by side so you compare real numbers on a written sheet.
Common Custom Windows & Doors Problems We See in Los Angeles Homes
- Concealed water intrusion behind stucco. A flashing failure at a window rough opening stays hidden for months in Los Angeles because the dry season is long. Then the first winter rain event arrives and the homeowner notices bubbled plaster or a musty smell near the window. By then the sheathing is wet and repair costs have moved up. We detail back-dam flashing and tape every opening so water gets managed before it ever reaches the wall cavity.
- Corroded steel casement frames from 1930s construction. Original steel casements in Los Angeles bungalows rust into the jambs and seize shut over decades. A full-frame tear-out is the only real fix, and that triggers permit-driven upgrades to wiring and structural framing. We know what LADBS will flag when walls are open, so it goes into the contract as a written allowance instead of a surprise change order.
- Title 24 code non-compliance at permit inspection. A homeowner decides to replace a few windows, and the old single-pane glazing fails the SHGC requirement for Los Angeles’s Climate Zone 9 or 10. Now the project needs low-E dual-pane units after the walls are open, and the price moves. We flag this on the first visit and quote compliant units from the start.
- Fire-zone requirements in the hills. Los Angeles’s Very High Fire Hazard Severity Zones cover hillside communities from Hollywood Hills to Brentwood and Sunland-Tujunga. The California Building Code requires fire-rated window assemblies with tempered or fire-rated glazing on permitted replacement work in those zones. Out-of-area contractors miss this. We don’t. The glazing spec and the added material cost are in your quote on day one.
Pricing for Custom Windows & Doors in Los Angeles, CA
A standard custom vinyl replacement window in Los Angeles runs $900 to $1,800 per opening installed, depending on size and the condition of the rough opening. Custom shape windows with arched or radius tops add 20 to 40 percent over a rectangle of similar size. A full-frame tear-out of an original steel casement in a 1930s stucco bungalow starts around $2,200 per opening and moves upward if the framing is rotted or the flashing failed and the sheathing needs repair. Oversized glass panels and commercial storefront glazing are quoted per project, typically $150 to $400 per square foot installed depending on glazing type and access.
Several things move the price in Los Angeles: whether the project triggers a permit with LADBS, whether the home sits in a fire hazard severity zone, what’s behind the stucco when we open the wall, and which Title 24 climate zone applies to your address. We write allowances into the contract for known unknowns, and nothing gets changed without a written approval and a written price first. That’s a square deal. Call (888) 635-0804 for a free written estimate on your home in Los Angeles.

FAQs - Custom Windows & Doors in Los Angeles
A full-frame window replacement in a 1930s stucco home in Los Angeles does not automatically trigger a separate electrical inspection, but it frequently triggers a code upgrade requirement once the wall is open. LADBS inspectors enforce current electrical code on any work they can see, and if knob-and-tube wiring runs through the rough openings, the inspector will flag it. That’s why TruePane writes a per-opening allowance into the contract for possible rewiring and new tempered glazing before we open the wall. The price gets approved in writing first. If you’re planning window work in a 1930s Los Angeles bungalow, call (888) 635-0804 and we’ll walk the house and give you a written estimate that anticipates what the inspector will see.
For a west-facing window in Los Angeles Climate Zone 10, Title 24 requires a maximum Solar Heat Gain Coefficient of 0.23 or lower depending on the permitted window area and orientation. West-facing glass takes the full brunt of afternoon sun in Los Angeles, so a standard dual-pane unit that fails that threshold won’t pass LADBS inspection. We quote low-E coatings specifically to meet or beat the 0.23 SHGC requirement on paper, registered with the manufacturer before installation. For the exact value your project requires based on window size and overhang shading, call (888) 635-0804 and we’ll run the numbers on your specific opening.
Steel casements in Los Angeles Spanish Colonial bungalows cost more to replace because they require a full-frame tear-out rather than a simple sash replacement, and because the arched and decorative rough openings they sit in don’t match standard stock window sizes. The original frames are usually rusted into the jambs, the rough opening is often out of square after ninety years, and the stucco reintegration around the new unit has to be detailed so water doesn’t find a path behind the wall. Then there’s the permit: LADBS will look at what’s exposed, and old wiring or undersized framing may trigger a code upgrade. We write these allowances into the contract in writing before we touch the wall. Call (888) 635-0804 for a detailed quote on your bungalow.
Yes. Simulated divided lites and architectural grilles let you keep the Craftsman divided-lite appearance while the insulated glass unit behind them meets California’s Title 24 SHGC and U-factor requirements. The grilles sit either between the panes or on the interior and exterior surfaces, depending on the manufacturer and the look you want. TruePane is an authorized installer for PGT, CGI, and ES Windows, and we quote SDL options side by side with true divided lite pricing on paper so you see the full cost trade-off in writing. Call (888) 635-0804 and we’ll bring samples to your Los Angeles home for a free estimate.
Homes in Brentwood that fall within a Very High Fire Hazard Severity Zone must use fire-rated window assemblies with tempered or fire-rated glazing under the California Building Code. That means a custom window replacement in those Los Angeles hillside neighborhoods can’t use standard annealed glass, and the added material cost is meaningful: fire-rated glazing adds 25 to 45 percent over comparable non-rated units. LADBS enforces this on permitted replacement work, and out-of-area contractors often miss the requirement until the inspector flags it. We check the fire hazard zone for every Los Angeles address before we quote, so the glazing spec and the cost are on the paper the first time. Call (888) 635-0804 for a free estimate on your Brentwood home.
