Window Replacement in Union City - Free In-Home Measure, Written Price

Fast, Reliable Window Replacement Across Union City

Window replacement in Union City runs $650-$1,400 per window for vinyl inserts in a standard 1960s tract home; full-frame replacement with new construction windows typically lands between $1,100-$2,300 per opening. Labor for a full-house job of 8-12 windows generally completes in two to four days once materials arrive. The price you pay turns on two things we see every week in Union City: the condition of the hidden framing behind the old window, and whether the opening is still square after decades of bay-mud settlement. Call (888) 635-0804 and we’ll measure every opening, check the framing, and give you a written line-item quote so you know exactly what you’re paying for.

Why TruePane Windows & Doors Is Union City’s Preferred Window Replacement Company

TruePane is led by Dale Kessler, a second-generation glazier who built this company on one rule: if the pane is not true, the job is not done. That standard matters more in Union City than in most East Bay cities because of what’s under the ground. The western flatlands near Alvarado and Decoto sit on compressible bay mud that has been settling, slowly and unevenly, since those 1960s tract homes went up. Framing that was square in 1968 usually isn’t square now, and a replacement window that goes into an unshimmed, racked opening will bind within a season or two. Our crews are trained to check every rough opening for plumb and level before the new window is set, and to correct what’s off before it becomes a callback.

We’ve been at this long enough that Union City homeowners call us about specific problems, not just “new windows.” A sagging door near the Alvarado flats, a fogged double-hung on a Decoto original, condensation between panes in a house three blocks from the rail line. The person who picks up the phone is a person, not a menu. You’ll get the same answer at midnight as you would at noon, because we staff our phones around the clock. When a technician arrives in 94587, they wear a uniform, they lay down drop cloths, and they explain what they’re doing in plain English. That’s not a marketing promise. That’s how Dale set the shop up.

Our Window Replacement Services in Union City

Every job we do in Union City starts with an inspection of the opening, not just the window. That’s where the difference lives. Here’s what we handle most often:

Insert Window Replacement

Insert replacement is the right call for most Union City homeowners when the original 1960s or 1970s frames are still structurally sound. We pull the old sashes, set a new vinyl or fiberglass insert into the existing frame, shim it plumb and level, insulate the perimeter, and cap the exterior. In Union City, the catch is usually the frame itself. Decades of salt-laden marine air sweeping off the Dumbarton Bridge corridor pits and oxidizes the old aluminum, so we inspect the frame corners and sill before quoting, not after. If the frame is compromised, an insert won’t cure it.

Full Frame Replacement

Full frame replacement means tearing out the entire window down to the rough opening, repairing or replacing damaged framing, and installing a complete new window with fresh flashing. It’s the job to choose when water damage has rotted the sill, when insects have eaten the jambs, or when the old aluminum frame is beyond salvage. In Union City, full frame replacement often triggers a permit and a code inspection, which can require shear panel or waterproofing upgrades once the wall is open. We handle the permit, schedule the inspection, and write allowances into the contract so you’re not paying a surprise change order. Our Window Replacement team has done hundreds of these on 1960s and 1970s tract homes across 94587.

Storm Window Replacement

Union City doesn’t get hurricanes, but it gets something quieter and more persistent: wind-driven salt air. Storm windows on older homes here are often secondary aluminum units mounted outside the primary sash. By the time we see them, the glass is usually fine but the frame is corroded, the track is warped, and the weatherstripping has gone to dust. We replace them with clean new storm units sized to the actual opening, and we check the primary window behind them for seal failure while we’re at it. A corroded storm window is often a symptom of the same problem that killed the window behind it.

Energy-Efficient Upgrade

Union City’s marine layer keeps afternoons cooler than inland cities, but that also means your house is pulling in damp bay air at night, and old single-pane aluminum leaks heat all winter. Replacing originals with dual-pane, low-E glass with argon fill drops the drafts and the condensation. In this city, we also spec glass that handles the specific condition of the western flatlands: high humidity against a warm interior creating between-pane condensation in failed seals. CWS and PGT both make lines we install regularly in Union City because their spacer systems hold up to that constant moisture cycling better than older technology.

Trusted Brands We Service in Union City

We’re an authorized installer for more than a dozen manufacturer lines, including Ply Gem, PGT, and CWS. What that means for Union City homeowners is simple: the warranty is real, it’s registered in writing before the truck leaves your driveway, and if a part fails, we handle the claim. We don’t sell a brand we wouldn’t put in our own mothers’ houses. On 1960s Decoto and Alvarado tract homes with racked openings, we often recommend a vinyl line like Ply Gem because the frame flexes slightly with the structure instead of fighting it. On homes with wider exposure to bay wind, a reinforced PGT coastal line makes more sense. We’ll quote the options side by side on paper with numbers, not adjectives.

Common Window Replacement Problems We See in Union City Homes

• Original single-pane aluminum windows with corroded frames. Sixty years of salt-laden marine air off the Dumbarton Bridge corridor pits and oxidizes aluminum. The sashes bind, the thermal breaks fail, and the glass fogs from failed seals. Patching these is a losing game; replacement is nearly always the sound call.
• Racked openings from bay-mud settlement. The western flatlands near Alvarado and Decoto sit on compressible soil that settles unevenly. We regularly measure rough openings that are out of square by a half-inch or more. A new insert into that opening will bind unless we shim and correct the plane before setting the frame.
• Hidden framing rot behind the old trim. Wind-driven moisture off the bay gets behind old flashing, and the original wood sills rot from the inside out. When we open the wall for a full-frame replacement, we frequently find water damage that was invisible from the outside. The permit then requires the repair, the shear upgrade, and the new waterproofing, and that is exactly where cheap bids go sideways.
• Failed weatherstripping and seals from constant temperature swings. The marine layer drives a steady indoor-outdoor temperature differential that stresses window seals, and condensation forms between the panes. The fix is a proper dual-pane unit with a real spacer system, not another tube of caulk.
