Fast, Reliable Window Replacement Across San Jose
Window replacement in San Jose runs $350 to $1,900 per window installed, with full-frame work on older ranch homes typically landing between $800 and $1,900. Our crews know the difference between a Naglee Park Craftsman that needs historically sensitive inserts and an East San Jose ranch where the original aluminum sliders are long past saving.

We’ve been setting windows in this valley since 2008 through Dale Kessler’s shop, and the work has always come down to one rule he keeps on the whiteboard: if the pane is not true, the job is not done. That holds twice in San Jose, where the summer heat trap and the old subsidence zones test every flashing detail and every frame alignment.
Why TruePane Windows & Doors Is San Jose’s Preferred Window Replacement Company
San Jose homeowners don’t have the same window problems as people on the Peninsula. The Santa Clara Valley sits inland and enclosed, so our summer afternoons run 15 to 25 degrees hotter than San Francisco, and the old aluminum sliders that came with 1950s and 1960s tract housing conduct that heat straight through the wall cavity. We walk into homes in Berryessa and Alviso where the indoor temperature hit 101°F last July with the AC running. That’s a glass spec problem, not an HVAC problem.
Dale Kessler founded Window Replacement work at this company in 2008 on a simple principle: out-of-true installs and voided warranties were problems worth fixing permanently. He had spent years in the trade watching manufacturers deny claims because someone skipped the paperwork or set a frame a quarter inch out of square. The Keystone Standard is our answer. Both manufacturer warranty layers get registered in writing before the truck leaves your driveway, durations stated, and every job carries the Done Right Promise. If it’s not done right, we make it right. No paperwork fights, no arguing.
We hire locally, train apprentices into journeymen, and plan to be in town in thirty years. A live person answers the phone 24 hours a day, 7 days a week. Not a voicemail tree, not a callback form. Call (888) 635-0804 and you’ll get a person.
Our Window Replacement Services in San Jose
We install, replace, and service windows and doors for residential homeowners across San Jose, with a focus on the work this valley actually needs: cutting solar heat gain, rebuilding openings that subsidence has racked, and replacing fogged or failed units before moisture spreads into the framing.
Energy-Efficient Upgrade
This is the service that matters most in San Jose’s heat trap. The city’s enclosed valley geography and urban heat island effect make low-SHGC dual-pane glass a functional necessity, not a luxury upgrade. California Title 24 mandates specific SHGC and U-factor thresholds on every replacement window, and a typical energy-efficient upgrade in San Jose runs $450 to $1,400 per window depending on frame material and glass package. We spec low-E argon-filled insulated glass units with SHGC below 0.25 where the code calls for it, and we show you the numbers on paper before you sign anything.

Full Frame Replacement
When the frame itself is compromised, you can’t just slide a new sash into an old hole. Full frame replacement in San Jose typically runs $800 to $1,900 per window because we pull the old unit down to the rough opening, inspect the jamb for rot or subsidence damage, and rebuild what isn’t square before the new window goes in. In Alviso and the low-lying blocks near Coyote Creek, decades of groundwater over-pumping sank the ground several feet in places, and we regularly find door frames visibly racked and rough openings that are no longer square. A new window set into an out-of-true opening binds within the first season and the warranty dies with it. We fix the opening first.

Insert Window Replacement
For homes with structurally sound frames, insert window replacement is the cleaner, less invasive option. A typical insert install in San Jose runs $350 to $1,100 per window. We measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves. This is the right call for many Willow Glen bungalows where the original wood frames are solid and the homeowner wants to preserve the look without tearing into stucco.

Storm Window Replacement
Storm windows aren’t just for cold climates. In San Jose’s winter tule fog season, exterior storm units can buy a few more years out of an aging single-pane setup while you budget for full replacement. Storm window replacement typically runs $250 to $700 per unit in San Jose. We’ll be straight with you though: if the primary window is a 1963 aluminum slider, a storm unit is a bandage, not a cure. We’ll tell you when it’s time to stop patching.

Trusted Brands We Service in San Jose
TruePane is an authorized installer for more than a dozen manufacturer lines, including, PGT, CGI, and ES Windows. We quote them side by side on paper so you see exactly what you’re buying and what each warranty covers. We also work with high-spec coastal and inland lines like ECO Window Systems and CWS when a San Jose project calls for a particular glass package or frame profile. Parts for common lines are stocked locally, so we’re not waiting on a truck from out of state when you need a replacement sash or a new balance. If the pane is not true, the job is not done, and that starts with the glass we put in front of you.
Common Window Replacement Problems We See in San Jose Homes
- Original 1950s aluminum slider frames conducting heat directly into the wall cavity. These frames spike indoor temperatures above 100°F during Santa Clara Valley heat waves, and the old single-pane glass does nothing to stop it. The fix is a dual-pane low-E unit sized to the opening with a SHGC that meets Title 24.
- Subsidence near Coyote Creek and Alviso racks window frames. The ground sank several feet in some blocks over the 20th century, and we see rough openings that are visibly out of square. New units installed without correcting jamb alignment bind and leak within the first season.
- Tule fog season drives moisture behind old flashing tape into wood jambs. These jams rot out and cause seal failure in replacement insulated glass units. We strip the old tape, inspect the jamb, and flash it properly before the new window goes in.
- Fogged double-pane units in homes built during the 1970s and 1980s expansion. The seal fails, moisture gets between the panes, and the insulating value drops to nearly nothing. One fogged unit is a sign the rest of the house’s windows are approaching the same failure point.
Pricing for Window Replacement in San Jose, CA
You’ll pay more in San Jose than in Fresno and less than in Palo Alto. That’s the honest range. Insert window replacement in San Jose typically runs $350 to $1,100 per window. Full frame replacement runs $800 to $1,900. Energy-efficient upgrades with low-E argon-filled glass run $450 to $1,400. The price gap between a cheap inland-spec window and the version that actually survives this valley’s heat trap and fog season is real. A $300 vinyl insert with a high SHGC and a flimsy frame will fail within a decade. The coastal-spec or Title 24-spec unit costs more up front and holds up for twenty years. We don’t push the cheap spec because we’re the ones who’d be back to replace it. Call (888) 635-0804 for a free estimate with written line-item pricing, no surprises on the bill.
| Service | Typical San Jose Range (Per Window) |
|---|---|

| Full Frame Replacement | $800 - $1,900 |
| Energy-Efficient Upgrade (Low-SHGC dual-pane) | $450 - $1,400 |
| Storm Window Replacement | $250 - $700 |
Exact numbers depend on frame material, glass package, opening condition, and whether the rough opening needs alignment work before the install. What won’t change once we quote it: the price. We stand behind it.

FAQs - Window Replacement in San Jose
San Jose sits inland in the enclosed Santa Clara Valley, so summer temperatures regularly hit 95 to 105°F while San Francisco stays in the 60s and 70s under the marine layer. Lower SHGC ratings limit solar heat gain through the glass, which reduces cooling load and keeps indoor temperatures livable. Title 24 enforces these thresholds statewide, but they matter more in San Jose than in coastal Bay Area cities because the valley traps heat. Call (888) 635-0804 and we’ll show you the SHGC and U-factor numbers required for your specific project.
The first thing you’ll notice is heat. Original single-pane aluminum sliders from the early 1960s conduct solar heat directly through the metal frame into the wall cavity, and on a 100°F San Jose afternoon the wall around the window feels hot to the touch. The second thing is the frame binding. Aluminum sliders that old wear out their tracks, and subsidence in parts of Berryessa has racked the openings over time. The fix is a dual-pane low-E unit set into a squared opening, and that’s work we do every week in San Jose. Call (888) 635-0804 to schedule a free estimate.
Decades of groundwater over-pumping caused documented land subsidence across low-lying San Jose neighborhoods near the former bay marshlands of Alviso, and in some blocks the ground sank several feet over the 20th century. That shift racks door frames and window openings out of square. If we set a new window into an opening that’s no longer square, the sashes bind, the seals fail, and the warranty dies within the first season. We reset the jamb before flashing tape goes on. That’s the difference between a window that lasts twenty years and one that fights you every time you open it. Call (888) 635-0804 for an honest assessment of your openings.
The biggest difference shows up in your PG&E bill. A cheap vinyl insert with a high SHGC and no low-E coating lets solar heat pour through the glass, so your AC runs harder from June through September in San Jose’s heat trap. An ENERGY STAR-certified unit with a low SHGC and argon-filled insulated glass cuts that solar heat gain at the glass, not at the AC coil. We see San Jose homes where indoor temperatures dropped 15 to 20 degrees on hot days after replacing 1960s aluminum sliders with properly spec’d dual-pane units. The window pays for itself in cooling savings over time, and Title 24 compliance means the unit actually meets the code San Jose enforces. Call (888) 635-0804 and we’ll run the glass spec numbers on paper before you spend a dime.
No. Fog between the panes means the seal on the insulated glass unit has failed, moisture is inside the unit, and the insulating gas has leaked out. The window’s thermal performance collapses even though the glass still looks intact. A fogged unit is the early stage of rot in the surrounding frame if moisture keeps migrating into the jamb. We replace fogged units in San Jose every week, and the sooner you catch it, the less damage the frame takes. Call (888) 635-0804 for a free estimate on replacing a fogged unit before the wood around it starts to go.
