If your North Hills windows fog between the panes, stick in the frame, or let the summer heat pour in while the AC runs, you’re dealing with what we see most in the 91343 ZIP: post-WWII single-pane aluminum assemblies that have outlived their useful life. TruePane Windows & Doors handles window and door replacement, new installation, and repair across North Hills, with a live person answering the phone 24 hours a day at (888) 635-0804. We know the local housing stock, we know the quake-related framing quirks, and we measure every opening twice before a single pane is ordered.
Dale Kessler founded this company on a simple rule: if the pane is not true, the job is not done. That standard applies to every North Hills project, from a single fogged slider to a full-house window replacement.

Why North Hills Homeowners Choose TruePane Windows & Doors
Homeowners here tend to stay put. They’ve raised families in these homes, they’ve patched and repainted after the 1994 Northridge earthquake, and they’ve learned the hard way that the cheapest bid usually means a second bill later. That’s who we work for. TruePane has served local communities since 2008 through a craft tradition that started with a second-generation glazier and continues with journeymen we train in-house, not subcontractors we barely know.
We work throughout North Hills, including the blocks along Sepulveda Boulevard, the neighborhoods east of Bull Creek, the homes near Carl’s Jr. on Nordhoff, and the quiet streets around Rayen Park. When you call, a live person answers. When we schedule, we show up on time, in uniform, with a framing square in the truck because North Hills demands it. Background-checked technicians work in your home the way they’d work in their own mother’s. And every job carries the Done Right Promise: if it’s not done right, we make it right, no paperwork and no arguing.
Windows & Doors Services We Offer in North Hills
Window Installation
New construction or remodel, we set windows square to the rough opening, flash them properly, and register both manufacturer warranty layers before we leave. North Hills tract homes from the 1950s and 60s rarely have perfectly plumb openings, so we shim and square as a matter of course.
Learn more about our Window Installation in North Hills.
Door Installation
Entry doors, French doors, and side-lites get set level and weather-stripped for the Valley’s 30 to 40 degree daily temperature swings. A door that binds in July or drafts in January is a sign someone skipped the shims, and we don’t skip the shims.
Learn more about our Door Installation in North Hills.
Window Replacement
We remove the old aluminum single-panes that dominate North Hills tract homes and replace them with energy-efficient double- or triple-pane units rated for Valley heat. Most replacements in 91343 complete in a single visit, and we leave the opening cleaner than we found it.

Impact Windows & Doors
For homes that want windborne-debris protection along with sound dampening, we offer impact-rated lines from PGT and CGI. Given North Hills sits a mile from the Northridge epicenter, some homeowners want the extra structural assurance that impact glass provides.
Energy-Efficient Windows
Low-E coatings, argon fills, and thermally broken frames cut the heat gain that makes Valley summers so punishing. We’ll quote manufacturer lines side by side on paper so you can see exactly what you’re paying for.
Sliding & Patio Doors
Original aluminum sliders from the tract era get stiff, noisy, and drafty as rollers wear and tracks warp. We replace them with smooth-gliding modern sliding and patio door units and set them square so they lock properly.
Glass Railing Systems
Frameless and semi-frameless glass railings for patios, decks, and pool areas. ES Windows and CWS lines give you clean sight lines with the hardware to match.
Custom Windows & Doors
Odd-sized openings, arch tops, or a specific architectural look all fall under custom. We measure, quote manufacturer lines in writing, and order exactly what the opening needs, not the closest stock size.
Neighborhoods We Serve in North Hills

Why North Hills’s Climate & Housing Affect Windows & Doors
North Hills sits in the San Fernando Valley, where summer highs regularly pass 100 degrees while coastal LA stays 25 to 30 degrees cooler. The same day-to-night swing that bakes the stucco also expands and contracts aluminum window frames, strips weatherstripping, and turns single-pane glass into a heat conductor. Most homes here were built between 1950 and 1975 with original aluminum sliders and hollow-core exterior doors, and after 50 to 75 Valley summers, those assemblies are finished. Homeowners who replace them with energy-efficient units see the difference on their LADWP bill within the first full cooling season.
The other factor that separates North Hills from neighboring Reseda or Granada Hills is the 1994 Northridge earthquake. The epicenter was roughly a mile away, and the ground shaking racked rough openings, shifted headers, and left frames out of plumb in a way that got patched over but never fully re-squared. Our crews bring extra shims and a full framing square on every North Hills call, because an inch out of square on a 60-year-old opening is common here, and a standard off-the-shelf install will not fix it. If the pane is not true, the job is not done, and that rule gets tested more in this ZIP code than almost anywhere else we work.
Pricing for Windows & Doors in North Hills
Straight numbers, no mystery. A basic window replacement in North Hills typically runs $450 to $900 per window depending on size and glass package.

FAQs About Windows & Doors in North Hills
Expect $450 to $900 per window for standard replacements, $800 to $1,800 for energy-efficient sliders, and $1,800 to $4,500 for a patio or sliding door. Exact pricing depends on the opening size, glass package, and how much shimming the framing needs. Call (888) 635-0804 for a written, line-item quote, free of charge.
No. We quote fixed prices in writing before the first cut is made, and we don’t add surprise line items. If we open a wall and find hidden damage, we stop, show you what we found, and agree on the next step before we proceed. Call (888) 635-0804 and we’ll put that in writing.
Yes. When a project requires a permit under Los Angeles city code, we pull it, schedule the inspection, and make sure it passes. You’ll know before we start whether your job needs one. Call (888) 635-0804 to talk through the specifics for your house.
The 1994 Northridge earthquake had its epicenter about a mile from North Hills, and the ground shaking racked rough openings and shifted headers in thousands of post-WWII wood-frame homes. Many were patched and finished but never re-squared, which is why our crews carry extra shims and a framing square on every call here. A standard replacement won’t fix an out-of-square opening; it takes custom shimming and patient installation.
Most single window or door replacements finish in one visit, usually four to six hours depending on the size and condition of the opening. Full-house replacements take longer, and we’ll give you a clear schedule in writing before we start. Call (888) 635-0804 to get a timeline for your specific project.

What North Hills Customers Say
"A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G."French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."
- Marie S."Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A.
