AfterFast, Reliable Impact Windows & Doors Across Los Angeles
Impact windows and impact doors in Los Angeles are governed by California’s Title 24 energy code, which sets a maximum Solar Heat Gain Coefficient of 0.25 for most residential windows in Climate Zones 9 and 10. That single requirement disqualifies a large share of off-the-shelf national product lines and is the reason so many Los Angeles homeowners end up replacing windows twice. TruePane Windows & Doors installs code-compliant impact-rated units the first time, with both manufacturer warranty layers registered in writing before our truck leaves your driveway. Call (888) 635-0804 for a free estimate on impact windows and doors anywhere in Los Angeles.
We know what opening up a 1930s stucco bungalow in South Central actually turns up: corroded steel casements set into arched rough openings, flashing tape that gave up years ago, and framing that needs engineered anchorage once LADBS gets involved. That is the work we do every week. If the pane is not true, the job is not done.
Why TruePane Windows & Doors Is Los Angeles’s Preferred Impact Windows & Doors Company
We are a second-generation glazier’s shop, founded by Dale Kessler in 2008, and we have been doing this work long enough that Los Angeles homeowners call us after the other crew walked away. Our Impact Windows & Doors team works in homes the way we would work in our own mother’s house: background-checked, uniformed, measuring every opening twice, and quoting manufacturer lines side by side on paper before any work begins.
The Done Right Promise is on every job. If something is not right, we make it right. No paperwork fights, no arguing. That promise sits on top of The Keystone Standard: both manufacturer warranty layers registered in writing, with durations stated, before the truck leaves the driveway. A live person answers our phone 24 hours a day, seven days a week. Not a voicemail tree. Not a call center. A person who knows Los Angeles and can pull up your job file.
We serve the whole city, from the dense 1930s-1950s bungalow blocks anchored by ZIP 90001 in South and Central Los Angeles up into the hillside neighborhoods where fire-zone requirements change the entire conversation. Our crews live in this city, train apprentices into journeymen here, and plan to be answering the phone in Los Angeles thirty years from now.
Our Impact Windows & Doors Services in Los Angeles
Hurricane Impact Windows
Los Angeles homes built before 1960 overwhelmingly still carry single-pane wood-sash or steel-frame windows that fail both current Title 24 energy thresholds and modern impact standards. We replace them with impact-rated units sized to the actual rough opening, not whatever the big-box store happens to stock. In a 90001 courtyard apartment we measured last fall, every original window was a slightly different width. Custom sizing is not an upsell there. It is the only way the job works.
Impact Sliding Glass Doors
Sliding glass doors are where Los Angeles homeowners feel the seasons. The prolonged dry season shrinks and checks wood door frames, the hardware binds, and the weatherstripping seals let go just before the winter rains arrive. We install impact-rated sliding doors with proper back-dam flashing at the rough opening, so moisture cannot hide behind stucco for months before it shows up as rot. Most jobs are completed in a single visit.
Impact Entry & French Doors
An entry door on a Spanish Colonial Revival home is not a commodity. It carries the visual weight of the whole front elevation. We quote impact-rated entry and French doors from lines like PGT, CGI, and ES Windows side by side on paper, so you see the difference in glazing, hardware, and fire rating before you spend a dollar. For homes in Los Angeles’s designated Very High Fire Hazard Severity Zones, which stretch from Hollywood Hills to Brentwood and Sunland-Tujunga, we specify fire-rated assemblies that satisfy the California Building Code the first time.
Impact Garage Doors
Garage doors rarely get the same attention as front windows, but in Los Angeles they sit on the windward side of the house more often than homeowners realize. We install impact-rated garage doors and service existing ones, including track alignment and panel replacement. The stucco-clad architecture that defines this city means every penetration needs careful flashing, and garage door openings are no exception.

Common Impact Windows & Doors Problems We See in Los Angeles Homes
- Stucco-concealed water intrusion around original steel casements. In 1920s-1940s bungalows across South and Central Los Angeles, original steel frames corrode silently behind stucco. The first sign is often a soft spot around the interior jamb after a winter rain. By then the flashing tape is gone and the rough opening needs to be stripped and rebuilt.
- Painted-shut double-hung sashes in 1930s courtyard apartments. Decades of paint layers weld the sash to the stop. Forcing it open warps the sash, cracks the jamb, and racks the glass until the seal fails. The repair is a full replacement with properly sized units, not another paint job.
- Non-compliant big-box dual-pane units failing Title 24 review. A national chain dual-pane window with a SHGC of 0.32 will not pass plan check in Climate Zone 9 or 10. Homeowners who already paid for those units end up tearing them out and starting over. We check the SHGC on every line we quote and write the number on the estimate.
- Arched rough openings that standard stock units cannot fill. Spanish Colonial Revival and Craftsman homes from the 1920s-1940s routinely have arched or decoratively shaped window openings. Off-the-shelf rectangular units do not fit, and filling the arch with plywood is the kind of shortcut that reads as a mistake for the rest of the house’s life. We size glazing to the actual opening.
Pricing for Impact Windows & Doors in Los Angeles, CA
A typical impact window replacement in Los Angeles runs $1,400 to $3,200 per opening, installed. Impact sliding glass doors generally land between $4,500 and $9,500 depending on panel count, glazing package, and whether the opening needs fire-rated assemblies. Impact entry and French doors run $5,000 to $12,000, with hillside fire-zone requirements adding meaningful material cost. Impact garage doors typically run $3,800 to $8,500.
What moves the number in Los Angeles specifically is Title 24 compliance documentation, which we include on every permitted job, and the condition of the rough opening once the old unit comes out. If framing is rotted or the anchorage needs engineering, the price moves and we tell you in writing before we touch it. We do not give low teaser bids and then change-order the difference. A square deal means the number on the estimate is the number on the bill, and any surprise is priced and approved by you first. Call (888) 635-0804 for a free estimate with line-item pricing.

FAQs - Impact Windows & Doors in Los Angeles
When you pull a permit for window replacement in Los Angeles, LADBS applies current Title 24 energy requirements to the new units, which means a SHGC of 0.25 or better for most residential openings in Climate Zones 9 and 10. You are not required to upgrade every window in the house at once, but every window in the permitted scope must meet current code. Call (888) 635-0804 and we will tell you exactly which units on your project need what.
Because the original rough openings in most 1920s-1940s Spanish Colonial Revival homes are arched or decoratively shaped, and standard rectangular stock units will not fill them properly. On a 1939 stucco bungalow off South Central Avenue in 90001, our crew pulled out original steel casement windows set into arched rough openings, sized custom impact-rated glazing to the arch, and re-textured the stucco so the new units matched the home’s Spanish Revival lines. The alternative is filling the arch and ruining the house’s face. Call (888) 635-0804 for a free measurement.
It means the seal between the glass panes failed and the insulating argon gas that fills the gap dissipated. In Los Angeles, where we get 300-plus days of high UV exposure, a failed seal shows up fast as interior condensation and a window that no longer blocks heat. The fix is a new sealed unit, not a patch. We replace the glass and register the new unit’s warranty in writing before we leave. Call (888) 635-0804 to get a quote on replacement glass.
Homes in Los Angeles’s designated Very High Fire Hazard Severity Zones, which include portions of Hollywood Hills, Brentwood, and Sunland-Tujunga, must use fire-rated window assemblies with tempered or fire-rated glazing under the California Building Code. Standard dual-pane units do not meet the requirement and LADBS will flag them on plan check. We quote fire-rated impact lines from PGT and CGI specifically for these zones. Call (888) 635-0804 for a free estimate that gets the fire rating right the first time.
We inspect first, write allowances into the contract, and price any surprise in writing before we touch it. On that South Central job, the corroded jambs had compromised the flashing tape and LADBS required engineered anchorage once the walls were open. We stripped back stucco, installed proper back-dam flashing, and re-textured the exterior so the new units matched the house. You approve the number before we spend it. Call (888) 635-0804 to schedule your free estimate.
