If you live in San Jose, you know the drill: summer days that sit in the mid-90s, winter mornings wrapped in tule fog, and a house built when a single pane of aluminum was considered modern. Most homes here were framed between 1950 and 1975, and the windows and sliders that came with them have been losing the fight against the Santa Clara Valley sun for decades. TruePane Windows & Doors serves homeowners across San Jose with the same steady approach we’ve used since 2008: measure twice, quote on paper, register every warranty layer in writing before we leave. Call (888) 635-0804 and a live person will pick up, day or night, not a menu system.

Why San Jose Homeowners Choose TruePane Windows & Doors
The work we do in Willow Glen and Naglee Park looks different from what we schedule in Berryessa or East San Jose, and that’s the point. We don’t send a franchise playbook to a 1930s Spanish Colonial and tell it to behave like a 1965 ranch. Dale Kessler founded this company on a rule that’s still written on the whiteboard: if the pane is not true, the job is not done. What that means for you is a background-checked, uniformed technician who measures every opening twice, puts manufacturer lines side by side on paper so you can see exactly what you’re buying, and registers both warranty layers before the truck pulls out of your driveway. San Jose homeowners have trusted us with everything from fogged seals in Alviso to full replacement packages in the Rose Garden district. The work is backed by the Done Right Promise, which is exactly what it sounds like: if it’s not done right, we make it right, with no paper fight and no fine print that covers neither of us. A founding principle worth mentioning: we hire local, train apprentices into journeymen, and sponsor county fairs and church roof funds because we plan to be answering the phone in San Jose thirty years from now.
Windows & Doors Services We Offer in San Jose
Window Installation
New construction or full replacement, installed to California Title 24 standards without exception. We set windows square and level, flash them properly for the valley’s winter fog, and register both warranty layers in writing. Learn more about our Window Installation in San Jose.

Entry doors, patio doors, and side doors hung to close cleanly through every season. In San Jose’s older neighborhoods, that often means addressing a racked frame before the new unit goes in. Learn more about our Door Installation in San Jose.

Impact Windows & Doors
Rated for debris impact and built to meet the strictest coastal code, even though San Jose sits inland. We install CGI and Eco Window Systems lines for homeowners who want the rating and the paperwork to prove it. Learn more about impact-rated Window Installation in San Jose.
Energy-Efficient Windows
Low-SHGC dual-pane glass is a functional necessity here, not a comfort upgrade. We quote high-efficiency packages side by side with standard glass so you can see the dollar difference on paper. Learn more about energy-efficient Window Replacement in San Jose.
Sliding & Patio Doors
Multi-panel sliders and patio doors built for daily use, not for sticking. We replace worn tracks and tired rollers or install a complete new unit, whichever the opening calls for. Learn more about sliding & patio Door Installation in San Jose.
Glass Railing Systems
Frameless and semi-frameless railing for decks, balconies, and stairways, engineered to code and installed with the same truth-the-pane standard as every window we hang. Ask for a written quote on materials and labor. Learn more about our glass railing work through our Window Installation in San Jose page.
Custom Windows & Doors
For the odd-sized openings in older San Jose homes where nothing off the shelf will sit right, we order custom units from ES Windows and PGT, among others. The price is honest and the fit is correct the first time. Learn more about custom Door Installation in San Jose.
Neighborhoods We Serve in San Jose
Our technicians work across the San Jose valley floor daily, from the older tree-lined streets west of downtown to the postwar ranches that fan out toward the hills. Typical response for a repair or replacement consult in San Jose is same week, often sooner.

Why San Jose’s Climate & Housing Affect Windows & Doors
San Jose sits in the enclosed Santa Clara Valley, which means summer heat stacks up and stays put. Days regularly reach 95-105°F in July and August, a good 15 to 25 degrees hotter than San Francisco on the same afternoon. That’s the reason the city’s vast tracts of 1950s-1970s stucco ranch homes, spread across East San Jose, Berryessa, and Alviso in zip code 95101 and beyond, are full of original single-pane aluminum slider windows that turn afternoon sun into an oven. Low-SHGC dual-pane glass isn’t an upgrade here; it’s the only glass that makes sense. Then there’s the winter tule fog that settles onto the valley floor. Older door thresholds and wood jambs were never designed with that kind of moisture in mind, and we see the result every January: swollen jambs, failing seals, thresholds that leak. California’s Title 24 energy code layers mandatory SHGC and U-factor thresholds on top of all of it, which most other states never require. Any replacement window or door in San Jose has to clear that bar, and we size and quote every unit to comply, not just to fit.
Pricing for Windows & Doors in San Jose
Replacement windows in San Jose generally fall between $600 and $1,400 per opening, depending on size, frame material, and glass package. A standard 3-foot-by-5-foot dual-pane vinyl replacement window commonly runs $650 to $900 installed. Custom wood-frame work in older homes like those in Willow Glen and Naglee Park runs higher. Entry door replacement typically costs $1,400 to $3,200 installed, and sliding glass patio doors land between $2,200 and $4,800. These are honest ranges, not teaser numbers. We quote every job in writing before work starts, with no surprise line items on the bill. Seniors and veterans receive a permanent 5% discount.

FAQs About Windows & Doors in San Jose
Plan on $600 to $1,400 per window in San Jose, with an average standard dual-pane vinyl replacement running $650 to $900 installed. Custom shapes, wood interiors, and impact glass push the number higher. The exact quote depends on the opening size and the glass package, and we write it all down on paper before work starts. Call (888) 635-0804 for a free estimate, and ask about the permanent 5% senior and veteran discount.
Because the vast majority of the housing stock was built between 1950 and 1975, when aluminum frames and single panes were the standard. Those windows were never designed for a climate that regularly hits 95-105°F in summer, and after decades of valley heat they’ve warped, fogged, and lost their seals. Replacing them with low-SHGC dual-pane glass is the single largest energy and comfort improvement most San Jose ranch homes can make. We quote the replacement line by line, without the sales pitch.
Yes. Any job that triggers San Jose’s permit requirements gets permitted, inspected, and passed before we call the job complete. Title 24 compliance on replacement windows and doors is mandatory, and we handle the paperwork, the scheduling, and the inspection. That’s part of the written contract, not an optional add-on.
No. We write fixed pricing on a line-item quote before any work begins, and if we find rot or a racked frame mid-project, you’ll see the number and approve it before we proceed. No change orders slipped in at the end. That’s the square deal, and we’ve held to it since 2008.
Most single-story San Jose ranch homes with 8 to 12 openings are completed in one to two days, start to finish. A full-house replacement including a patio slider may take three. We’ll give you a schedule in writing before the job starts, and we’ll be there when we say.

What San Jose 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.
