Fast, Reliable Custom Windows & Doors Across North Hills
Custom windows and doors in North Hills usually start at $1,200 for a corrected rough opening and a properly sized unit, with most full replacements on earthquake-racked 1950s-70s homes landing between $2,800 and $9,000 depending on material, glass package, and frame condition. We’ve worked the 91343 ZIP long enough to expect what other installers miss: out-of-square jambs, shifted headers, and single-pane aluminum frames that gave up years ago. Call (888) 635-0804 and a live person answers – not a callback form, not a voicemail tree. We measure twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves your driveway.
North Hills sits within a mile of the 1994 Northridge epicenter. That single fact changes nearly every window and door job we take in this neighborhood, and it’s why our Custom Windows & Doors crew carries extra shims and a full framing square on every call.
Why TruePane Windows & Doors Is North Hills’s Preferred Custom Windows & Doors Company
We’re the company homeowners call after the first bid fell apart. That happens a lot in North Hills. A contractor quotes a standard replacement, the crew shows up, discovers the rough opening is an inch out of square, and suddenly the homeowner is staring at a change order. Our technicians are background-checked, uniformed, and trained to expect exactly that condition before the first screw comes out. The quote you get is the price on the bill – no surprise line items, no second appointment left hanging.
Dale Kessler founded TruePane in 2008, but the trade runs deeper than that. Second-generation glazing, years of community service, and a whiteboard rule that names the company: if the pane is not true, the job is not done. We’ve built our North Hills reputation on that rule. Local homeowners call us after the fogged-seal guy disappeared, after the patio door started binding in July, after the “budget” replacement leaked during the first winter rain. We fix it and we stand behind it. Every job carries the Done Right Promise and The Keystone Standard – both manufacturer warranty layers registered in writing, durations stated, before we leave.
The phone rings and a live person answers. 24 hours a day, 7 days a week. That matters when your front door won’t latch at 9 p.m. or when the Santa Ana winds are whistling through a cracked jamb. We’re not a regional call center. We’re a company that sponsors county fairs and church roof funds in this Valley because we plan to be here in thirty years.
Our Custom Windows & Doors Services in North Hills
Custom Shape Windows
North Hills tract homes from the 1950s through the 1970s sometimes feature arched transoms, half-rounds, or angled picture windows that don’t match any stock catalog. Add a racked rough opening from the ’94 quake and you’re not looking at a replacement – you’re looking at a custom build and a careful re-shim job. We measure every opening twice, cut and assemble to the actual dimensions of your frame, not the dimensions the original builder intended. In 91343, custom is often the default, not the upgrade.

Architectural Grilles & SDLs
Simulated divided lites, or SDLs, give a window the look of individual panes without sacrificing the thermal performance of modern insulated glass. For North Hills homeowners who want to keep the mid-century character of their original wood or aluminum windows while gaining low-E glass and argon fill, SDL grilles are the right move. We offer true divided lites where the design calls for them, and exterior-applied grilles where budget matters. Either way, the frames get built square and sealed tight against Valley dust and heat.

Oversized Glass Panels
Some North Hills homes were built with wide front picture windows – six feet, eight feet, even ten feet across. When those single-pane originals fail, they fail big. We source and install oversized insulated glass units rated for the San Fernando Valley’s 30-40 degree daily temperature swings. The glass is heavy, the handling is precise, and the framing has to be dead true or the seal fails early. We do this work with full framing squares, proper shim packs, and flashing tape at every perimeter. The result is a panoramic window that opens and closes like it was meant to for another fifty years.

Commercial Storefront Glazing
North Hills runs commercial along Sepulveda Boulevard and Roscoe Boulevard, and storefront glazing in this heat takes a beating. We install and replace aluminum storefront systems, glass doors, and interior partitions for small businesses in the 91343 ZIP. Same standard applies whether it’s a storefront on Sepulveda or a showroom on Nordhoff: measure, square, seal, and register the warranty in writing.

Curtain Wall Systems
Larger commercial and mixed-use buildings in North Hills occasionally need curtain wall work – the exterior glass skin that carries its own weight and resists wind load. We handle curtain wall replacement and repair with the same care we give a 1972 stucco ranch house. The stakes are higher, the glass is bigger, and the tolerance for an out-of-square anchor is zero.

North Hills homeowners deserve a square deal, and we put it in writing.
Common Custom Windows & Doors Problems We See in North Hills Homes
- Racked rough openings from the 1994 Northridge earthquake. A surprising number of post-WWII wood-frame stucco homes in 91343 have jambs that are an inch or more out of square. A standard replacement window won’t seat properly in that opening – it binds, leaks, and voids the manufacturer warranty. We correct the rough opening with custom shim packs and flashing before the new unit goes in.
- Original aluminum single-pane sliders warped by Valley heat. North Hills regularly sees summer highs above 100°F while coastal LA sits at 75°F. Add the 30-40 degree nightly drop and aluminum frames fatigue fast. Miter joints loosen, glass seals break, and the window becomes a thermal hole. We replace these with fusion-welded vinyl or thermally broken aluminum rated for this climate.
- Hollow-core exterior doors that bind in July. Those 1960s and 1970s original doors expand and contract with the heat. By mid-summer, the deadbolt misses the strike plate and the door won’t close without a shoulder. We install properly hung, insulated steel or fiberglass doors with adjustable thresholds that hold their alignment through the seasonal swings.
- Insulated glass seal failure in under a decade. We see this constantly on cheap replacement jobs done by crews that didn’t understand Valley thermal cycling. The seal fails, the glass fogs between the panes, and the “energy efficient” window is now worse than the original. We spec glass packages rated for this climate and register both warranty layers before we leave the driveway.

FAQs - Custom Windows & Doors in North Hills
North Hills sits within about a mile of the 1994 Northridge earthquake epicenter, and the ground shaking that day racked the rough openings in thousands of post-WWII wood-frame stucco homes. A jamb that’s an inch out of square won’t accept a standard replacement window – the unit binds, the seals fail, and the warranty is void. We correct the opening first with custom shims and flashing, then install a window sized to the actual frame. Call (888) 635-0804 to have us measure what you’re actually working with.
Yes. In most cases we cut the old frame out from the interior side, correct the rough opening with shims and steel straps, and set the new window without touching the exterior stucco beyond the immediate frame perimeter. The stucco face stays intact, and we flash the new unit so water can’t work its way into the corrected opening. This is standard practice for our North Hills crews because we see earthquake-racked frames on nearly every job in 91343.
North Hills sees 30-40 degree daily temperature swings through summer, with highs above 100°F. Aluminum expands and contracts dramatically under that cycling, which stresses the miter joints and the glass seal. Within a decade, the insulated glass unit fogged and failed. Coastal LA never sees those extremes, so the same window lasts longer there. We spec fusion-welded vinyl or thermally broken aluminum with glass packages rated for the Valley’s thermal range.
Most city-code requirements for North Hills don’t mandate impact-rated glazing for typical single-family homes. That said, if you’re near the Sepulveda Basin or close to the 405/5 interchange, wind-driven debris and vibration are real considerations. PGT and CGI impact lines hold up better against both. We’ll walk you through what code requires, what your insurance may discount, and what we recommend based on your specific lot and exposure. Call (888) 635-0804 for a straight answer on your house.
A basic off-the-shelf window from a home center might list for $200 to $400, but by the time you factor in the correction of a racked opening, proper flashing, labor, and disposal, you’re looking at $1,200 to $3,200 for a proper vinyl replacement in North Hills. Custom shape windows, oversized glass, and SDL grilles push that to $3,000 to $9,000. The cheap spec costs more within a decade when the seal fails or the jamb binds. Get a free itemized quote: (888) 635-0804. We’ll tell you exactly what the correction work costs and why it matters.
