Why Northridge Homeowners Choose TruePane Windows & Doors
Northridge has a particular housing story, and we’ve seen it play out on thousands of properties here. From the ranch homes north of Cal State Northridge to the tree-lined streets in Sherwood Forest, many of the windows and doors in this community were either left behind by the 1994 earthquake rebuilds or rushed in to replace what the quake broke. That means the next contractor who walks your property should know how to spot a rough opening that looks square but isn’t. Ours do. Dale Kessler built TruePane on a rule that governs every job we take: if the pane is not true, the job is not done.
TruePane has been at this since 2008 as a working glass business. We’re a second-generation glazier’s company, not a franchise that parachutes into a zip code. Our technicians are background-checked, uniformed, and trained in-house. They measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves the driveway. Northridge homeowners in 91324 routinely tell us the two things they value most: we show up when we say, and we stand behind the work.

Why Northridge’s Climate & Housing Affect Windows & Doors
Northridge sits deep in the inland San Fernando Valley, where summer temperatures regularly reach 105 to 110 degrees. That’s fifteen degrees hotter than the coast, and it punishes glass. Seals fail faster. Vinyl and aluminum frames expand and rack. A west-facing window without low-E glazing isn’t a comfort issue here; it’s a utility bill you pay every month from June to October. Title 24 compliance matters in Northridge because the heat load is real, not theoretical.
Northridge is also ground zero of the 1994 earthquake. The wave of rebuilding in the mid-to-late 1990s means thousands of homes here received windows and doors that are now reaching the end of a 25 to 30 year service life, all at the same time. On top of that, many of those post-quake frames and rough openings were repaired under emergency permits, sometimes with sister-framing or steel plates instead of full header replacement. What looks square at a glance often isn’t. We carry the experience to size and shim a modern window around framing that predates the original spec sheet by a generation of patchwork.

FAQs About Windows & Doors in Northridge
A standard window replacement in Northridge typically runs $600 to $1,100 per window installed, while impact-rated windows from PGT or CGI generally land between $1,200 and $2,400 installed. The spread depends on frame material, glazing, and whether the rough opening needs corrective shimming or header work. Call (888) 635-0804 for an exact quote, free.
The 1994 Northridge earthquake triggered a massive wave of rebuilding, and thousands of homes received windows and doors during that mid-to-late 1990s reconstruction. Those units are now 25 to 30 years old, which is exactly when aluminum sliders and basic dual panes hit the end of their useful life. If yours fog, bind, or leak heat, you’re not alone. Estimates are free when you call.
Yes, and we treat them as their own animal. Rough openings in post-1994 rebuilds often have sister-framing or steel plates behind the trim, which means a stock-size window may not sit true without careful shimming. We measure everything twice and quote to the frame as it actually is. Call us to have a technician check your openings.
No. Your written quote is the price you pay unless you add to the scope yourself. The Keystone Standard is simple: both warranty layers registered in writing before we leave, workmanship guaranteed for 90 days, no fine print and no arguing. Call (888) 635-0804 to get your number on paper.
We don’t sidestep permits when the job requires them. For structural work like widening an opening or replacing a header, we make sure the paperwork is filed and the inspection is passed. For straight swaps into existing openings, we move on your timeline. Ask us on the phone and we’ll tell you straight what your job needs.

What Northridge Customers Say
"Impact windows on the whole house. They handled the permit, the inspection, and gave me a folder with every approval number for the insurance company. My windstorm premium dropped enough to notice."
- Bill T."Whole-house window replacement at 71 years old is not something you want to do twice. Dale walked the house himself for the quote. Crew was the same three men all four days, and the foreman knew every window by room."
- Pat and Ray L."Eleven windows replaced in two days. The crew chief, Marcus, showed me the level on every single frame before they caulked it. My wife noticed the street noise was gone before I did."
- Ronald P.
