We’re Window Replacement specialists who grew up in this trade. Not a franchise, not a sales org with subcontractors. Our crews know the difference between a Topanga Canyon hillside custom and a flatland Calabasas Park stucco box, because we’ve worked both since 2008.
Why TruePane Windows & Doors Is Woodland Hills’s Preferred Window Replacement Company
Dale Kessler founded TruePane in 2008 on a rule that still governs every install: if the pane is not true, the job is not done. That’s not a slogan. It’s the standard our background-checked, uniformed techs apply to every opening we touch in Woodland Hills, from Warner Center condos to the ranch tracts south of Ventura Boulevard.
We know what Woodland Hills heat does to single-pane aluminum. We know what a Santa Ana wind event does to a thin jamb with builder-grade weatherstripping. And we know what a permit inspector looks for when a full-frame replacement triggers compliance review under Chapter 7A. That local knowledge is why homeowners here call us first, and why they call us back when they add a second phase.
Every job carries the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves your driveway. No paperwork fights. No arguing. A square deal on paper.
We’ll be there when we say. Punctual, uniformed, prepared. Dispatch is coordinated from our Los Angeles office, but the crews we send to Woodland Hills are local hires who plan to be working this valley in thirty years.
Our Window Replacement Services in Woodland Hills
Full Frame Replacement
Older Woodland Hills homes, especially the 1950s-60s ranch tracts that dominate 91364, often have original aluminum windows set straight into framing with no proper flashing. Full-frame replacement removes the entire unit, letting us rebuild the rough opening, install new flashing tape to the water-resistive barrier, and set a window that’s actually square. In Woodland Hills this work frequently triggers a Chapter 7A compliance review, so we quote fire-rated multi-pane options side by side on paper so you see exactly what the permit requires.

Insert Window Replacement
If your existing frames are sound and the openings are square, insert replacement installs new sashes and hardware inside the old frame. It’s faster, typically $850-$2,400 per opening in Woodland Hills depending on size and glass package. But if we open that wall and find drywall mud where flashing should be, or a jamb that’s sagged from years of heat, we’ll stop, show you photos, and price the fix before we touch it.

Storm Window Replacement
Woodland Hills sits in a heat bowl that regularly holds multi-day stretches above 105°F, then gets hit with Santa Ana wind events that create extreme pressure differentials across glass. Storm windows here aren’t about winter. They’re about ember season and wind-driven ash. We install impact-rated and ember-resistant storm assemblies that keep smoke out when the gusts push hard against thin original sashes. For properties in the Very High Fire Hazard Severity Zone, this is often the difference between a defensible window and a failed inspection.

Energy-Efficient Upgrade
Woodland Hills holds the all-time Los Angeles County temperature record: 121°F on September 6, 2020. Original single-pane aluminum windows in this valley can hit interior surface temperatures above 120°F, which is why east- and west-facing rooms become unusable without continuous AC. We upgrade to dual-pane low-E argon-filled units with thermally broken frames, and we spec coatings based on which direction your glass faces. A west-facing wall on a 1970s ranch off Platt Avenue needs different glazing than a shaded north window. We quote it that way.

Historic Window Restoration
Some Woodland Hills owners want to keep the original look. We get that. Wood sashes from a 1950s ranch have a character you can’t buy off a shelf. We can rebuild those, replace the glass with energy-efficient panes that fit the original frame, and restore hardware instead of replacing it. What we won’t do is pretend a 70-year-old single-pane window meets current fire-hardening code. We’ll show you the gap in writing and let you decide.

Common Window Replacement Problems We See in Woodland Hills Homes
- Radiator windows in the heat bowl. Single-pane aluminum with no thermal break is everywhere in 91364, and in summer those panes get hot enough to warp vinyl frames and cook the seals out of dual-pane retrofits. We see fogged glass and sagging sashes on nearly every pre-1970 ranch we open up.
- Chapter 7A failures on ranch homes. Original 1950s-60s windows lack the tempered, multi-pane, ember-resistant assemblies the WUI code requires. Any permitted remodel or insurance remediation triggers the compliance review, and suddenly your “cosmetic” window swap is a fire-hardening mandate.
- Santa Ana air infiltration. The wind pressure differential in Woodland Hills during Santa Ana events forces air through aged builder-grade weatherstripping and skinny jambs. Homeowners smell smoke indoors even with windows closed, and sashes rattle off their tracks. That’s a flashing and jamb problem, not just a weatherstrip problem.
- Insurance-driven replacement. Since the Woolsey Fire, insurers in hillside LA are writing renewal conditions that require fire-rated windows and doors. We walk customers through what their policy quote means in practical terms, and what a compliant package actually costs.

FAQs - Window Replacement in Woodland Hills
Yes, in many cases. Woodland Hills sits inside Los Angeles County’s Very High Fire Hazard Severity Zone, so any window replacement that triggers a permit on a qualifying property must meet California’s WUI Building Code Chapter 7A, which requires fire-rated, multi-pane, ember-resistant assemblies. A straight insert swap might not trigger it, but any full-frame work or larger renovation generally will. Call (888) 635-0804 and we’ll tell you where your property stands before you commit to anything.
Because they are. Single-pane aluminum with no thermal break conducts heat straight through the frame and glass, and in Woodland Hills’ valley bowl, interior surface temperatures can exceed 120°F on east- and west-facing walls. That heat has nowhere to go. It warps parts, cooks seals until they fog, and makes rooms unusable without AC. Replacing them with dual-pane low-E units with thermally broken frames drops that surface temperature by 30-40 degrees. Call us for a free estimate on an energy-efficient upgrade.
Yes, and it usually does on older homes. On a 1962 ranch near Ventura Boulevard, our crew opened a wall for a full-frame replacement and found the original aluminum window had been flashed with nothing but drywall mud. No tape, no barrier, nothing. We cut back the stucco, installed new flashing tape to the water-resistive barrier, and set a dual-pane low-E double-hung rated for Chapter 7A in its place. We also repaired the sagging jamb on the adjacent sliding door. That’s standard practice for us here, not an exception. Any surprise gets priced and approved in writing before we proceed.
It depends on the manufacturer and whether the warranty was registered properly. TruePane registers both manufacturer warranty layers in writing, with durations stated, before the truck leaves your driveway. If we installed the window and it fogs within the warranty period, we handle the claim and the replacement under our Done Right Promise. If it’s an older window installed by another company, we’ll still inspect it and tell you honestly whether repair or replacement makes more sense. Estimates are free.
Yes, and here’s why it matters more here than almost anywhere else in LA. Your AC is fighting against glass that hits 120°F on the inside. Dual-pane low-E argon units cut solar heat gain by 40-60% on west-facing walls, which in Woodland Hills’ heat bowl translates directly to lower cooling loads in July, August, and September. The exact savings depend on your home’s orientation and window count, but most customers feel the difference within the first Santa Ana stretch. Call (888) 635-0804 for a precise quote on your specific openings.
