Fast, Reliable Window Replacement Across Los Gatos
Window replacement in Los Gatos runs about $750 – $1,400 per window installed for a standard vinyl double-hung, and a full-home project on a 1960s ranch typically lands between $12,000 and $28,000 depending on glazing specs, frame condition, and how many units need full-frame work versus insert replacement. Juniper Windows & Doors coordinates scheduling and dispatch from our San Francisco Bay Area office, with crews serving Los Gatos locally every week. If you live off Kennedy Road, up in the Almond Grove area, or anywhere in the 95030 or 95032 ZIP codes, call (682) 281-2168 and we’ll get you a written price before anything gets ordered. That’s how we work. No door-knock estimate that drifts upward later.
Why Juniper Windows & Doors Is Los Gatos’s Preferred Window Replacement Company
Los Gatos homeowners call us for one reason more than any other: a locked, written price. Sean Mackey runs the team, and he’s held the same line since we started installing windows in 2001 as part of the Relay Home Co. family. You get a scope in writing, a line-item dollar figure, and the 365-Day Done Right Promise covering parts and labor for a full year after installation. If something isn’t right, we come back and make it right. No charge. No argument.
Homeowners here don’t have time for a four-hour window with no live tracking. Our Relay Visibility Guarantee fixes that. You book, you get a live arrival time you can track on your phone, before-and-after photos of every job, and a digital invoice you can pay from a link. The person who shows up at your Los Gatos door is background-checked and in uniform. You know exactly who’s walking up the driveway.
And when you call, a live person answers. 24/7. Not a voicemail maze. That matters when you’re trying to get a project scoped around school pickup on Daves Avenue or a work commute up Highway 17.
Window Pane Replacement in Los Gatos
Window Pane Replacement in Los Gatos usually means the sash and frame are still solid, but the glass unit itself is blown, cracked, or fogged, so we swap just the insulated glass unit (IGU) rather than the whole window. For a standard double-pane IGU in a vinyl or aluminum frame, expect $180 – $450 per pane in Los Gatos, including labor and haul-off. It’s the cheapest way to fix a failed window without tearing into the wall opening. And in this town, it’s often the right call on mid-century homes where the original frames are still square and true.
When the Glass Fails but the Frame Is Fine
Fogging between panes means the seal has failed and the argon or krypton fill is gone. In Los Gatos, where winter mornings drop into the 30s and summer afternoons climb past 100, that failed seal means condensation you can’t wipe away and a window that’s no longer insulating anything. Replacing just the pane stops the problem without the cost of a full tear-out.
The Right Glass for the Opening
We field-measure every opening before ordering. Los Gatos has plenty of older homes where the original sash isn’t a standard stock size anymore. That’s normal for us. We order the IGU to the actual opening dimension and match the low-E coating to the exposure, which keeps one side of the house from baking in August while the other side stays comfortable.
Window Seal Repair in Los Gatos
Window Seal Repair in Los Gatos addresses the gasket, glazing bead, or weatherstripping that keeps air and water out at the jamb, not the glass itself. It runs $120 – $320 per window in Los Gatos depending on whether we’re re-gasketing a vinyl sash, re-bedding a fixed pane, or replacing dried-out weatherstripping on a casement or slider. A failed seal is the first thing you notice when a room feels drafty in January or dust collects along the sill faster than the rest of the house.
Caught Early, It’s a Small Fix
Most seal problems we see are on the operable sash of aluminum and vinyl windows, especially west-facing units in Los Gatos that take the full afternoon sun. The gasket hardens, cracks, and starts letting air move through. Fixing the seal early keeps the window working and keeps the framing dry. Wait too long and water gets under the trim, and now you’re replacing stucco instead of a gasket.
When a Seal Repair Won’t Cut It
If the frame is twisted, the corner welds are pulling apart, or the sill is soft, seal repair just buys you a season. On older Los Gatos homes we sometimes find the original aluminum frame has worked loose from the rough opening. In that case, we’ll be honest: a Window Replacement is the better investment than chasing the leak with more caulk.
Trusted Brands We Service in Los Gatos
We stock and install from eight product lines, and for Los Gatos jobs the framers usually land on PGT, ViewLux, and CGI. PGT’s impact-rated lines make sense for hillside parcels in the WUI zone, ViewLux gives you a clean narrow sightline on mid-century modern remodels, and CGI handles heavyweight commercial-grade applications. Because we’re not tied to a single manufacturer, the right glazing spec for your lot never turns into a compromise. We keep local parts access for Los Gatos customers, which means ordering doesn’t stall a project for weeks.
Common Window Replacement Problems We See in Los Gatos Homes
- Skipped fire-zone glazing review. A crew quotes standard clear IGU on a hillside parcel off Shannon Road, and the town’s WUI review kicks the permit back. We spec tempered or multi-pane glazing for ember and radiant-heat resistance up front, so the permit clears the first time.
- Stock sizes ordered without field-measuring. Los Gatos has a run of mid-century remodels where the framed opening is out of square by an inch or more. A stock sash binds or the seal dies within a season. We measure every opening twice.
- Rot-soft trim reused at the jamb. On older homes near Los Gatos High, the exterior stucco or wood trim at the sill is often soft from years of sprinkler overspray. A replacement that reuses it leaks at the sill. We write trim repair into the scope when it’s needed.
- Under-scoped flashing details. Without a re-flash at the rough opening, a heavy El Niño winter drives water behind the new unit. In Los Gatos, where winter storms come off the Santa Cruz Mountains, we don’t skip the flashing detail. It’s in the written scope.

FAQs About Window Replacement in Los Gatos
Yes, if you’re doing full-frame replacement or changing the rough opening size in Los Gatos, the town requires a building permit. Insert replacements that keep the original frame and opening dimensions may not need one, but anything in the hillside WUI zone will get a fire-zone glazing review. We pull the permit, schedule the inspection, and make sure the glazing spec matches what the town expects before we order anything.
If your home sits in the wildland-urban interface zone along the Santa Cruz Mountains foothills, yes, you likely need tempered or multi-pane glazing specified for ember and radiant-heat resistance, not just a standard low-E IGU. Los Gatos sits in a high-fire-severity zone, and the town’s WUI review will flag a standard clear-glass spec on a hillside parcel. We build that into the quote from day one. Call (682) 281-2168 and we’ll check your parcel.
Most re-inspections come down to glazing spec mismatch, where the installed unit doesn’t match what the permit called for, usually a fire-zone glazing detail on a hillside lot. The second most common is flashing at the rough opening that doesn’t meet current code. We’ve been through enough Los Gatos inspections to know both fail points, and our written scope covers them before the inspector ever shows up.
For a full-home window replacement in Los Gatos, figure 3 to 5 weeks from signed contract to final inspection. That includes field measuring, ordering (which runs 2 to 4 weeks for custom IGU and full-frame units), installation, and the town inspection. If the parcel is in the WUI zone, add a few days for the glazing review. We’ll give you a written timeline with the quote.
Yes, and it’s often the right move on Los Gatos mid-century homes where the original vinyl or aluminum frames are still square. A standard double-pane IGU swap runs $180 – $450 per pane, and it avoids tearing into the wall. We’ll tell you honestly if the frame has enough life left in it to make the pane-only fix worth it, or if a full replacement is the better spend.
