Fast, Reliable Window Replacement Across East Palo Alto
Window replacement in East Palo Alto costs more than a sash swap, and the reason is under your feet. Homes here sit on Bay fill that has settled unevenly for sixty-plus years, so rough openings rack out of plumb and the original aluminum frames corrode from salt air. We scope the frame correction before we quote the window. That is the difference between a bid that holds and one that turns into a callback. Call (888) 635-0804 and we will walk your house with you, measure every opening twice, and put the numbers on paper.
Key Takeaways
- Full frame replacement in East Palo Alto typically runs $900-$1,600 per opening; inserts run $500-$950 when the existing frame is square and sound.
- Bay-fill settling racks rough openings 1-2 inches out of plumb on older Weeks and University Avenue homes, so header shimming and jamb rebuilding are common line items here.
- Salt-laden marine air off the Bay corrodes aluminum sill pans and tracks faster than a few miles inland; bay-side homes need corrosion-rated flashing and sill details.
- We are an authorized installer for, PGT, and CGI, and we register both manufacturer warranty layers in writing before the truck leaves.
- Every job carries the Done Right Promise. If the pane is not true, the job is not done.
Why TruePane Windows & Doors Is East Palo Alto’s Preferred Window Replacement Company
Dale Kessler founded TruePane in 2008 on a rule he keeps on the whiteboard: if the pane is not true, the job is not done. We have spent years in the glass trade across the Bay Area, and the homes of East Palo Alto have taught us more about settling and salt than any spec sheet. Our crews show up in uniform, background-checked, and we measure every opening twice. We do not sub out the work to a rotating cast of day laborers. The team that quotes your job is the team that sets your windows.
East Palo Alto homeowners call us because we answer the phone, live, 24 hours a day. No voicemail tree, no regional call center. You get a person who knows what a racked header looks like and can tell you honestly whether you need a full frame replacement or whether inserts will hold. We pull permits when the scope requires it, and we stand behind the work in writing. The Done Right Promise is not a slogan. It means if something is not right, we make it right, no paperwork fight.
We also know this city block by block. The 1950s ranches off Weeks Street, the smaller bungalows near University Avenue, the newer infill rentals going up for the Silicon Valley workforce. Each one has different framing realities, and we price accordingly. When East Palo Alto customers call, they are not calling a franchise. They are calling a company that plans to be here in thirty years.
Our Window Replacement Services in East Palo Alto
Full Frame Replacement
Most East Palo Alto homes built in the 1940s and 1950s were never designed for modern window systems. The original aluminum or steel sashes sit in frames that have racked with the fill soil, and pulling the whole frame lets us rebuild the rough opening square, shim the header, and set a new unit that will not bind in July. In East Palo Alto, full frame replacement typically runs $900-$1,600 per opening depending on size, exterior trim condition, and how much jamb rebuilding the settling has forced. This is the right choice when frames are corroded, racked beyond shimming, or simply the wrong size for the opening.

Insert Window Replacement
If your existing frames are square and the rough opening is sound, an insert is the leaner option. We set a new sash package inside the old frame, preserving the interior and exterior trim. East Palo Alto homes that were remodeled in the 1980s and 1990s often qualify, but we will not sell you an insert if the frame is hiding corrosion or a seal failure. Inserts in East Palo Alto generally run $500-$950 per opening. We check every existing unit for fogging before we quote, because a failed seal behind a new insert is just a second bill waiting for you.

Storm Window Replacement
Storm windows serve double duty in East Palo Alto. The marine layer pushes morning fog through the Weeks neighborhood and along University Avenue, and single-pane originals condensate on the interior sill, feeding mold into old wood trim. A properly gasketed storm window stops that condensation cycle and quiets University Avenue traffic at the same time. Storm units in East Palo Alto typically run $300-$700 per window installed, depending on frame material and glass spec. We measure the reveal carefully, because a storm unit hung on a racked frame will bind within a season.

Energy-Efficient Upgrade
Bay-side homes in East Palo Alto eat window hardware. The salt-laden air works on hinges, tracks, and sill pans faster than a few miles inland, and the region’s single-pane originals are the single biggest heat-loss surface in a 1950s ranch. Dual-pane Low-E upgrades with argon fill cut the fog, the drafts, and the PG&E bill. In East Palo Alto, a full energy retrofit package typically runs $12,000-$28,000 for a three-bedroom ranch, depending on the number of openings and how much frame correction is required. We quote manufacturer lines side by side on paper so you see exactly what the glass and the gas fill are doing for you. Call our Window Replacement team and we will lay out the numbers for your specific block.

Trusted Brands We Service in East Palo Alto
We are an authorized installer for more than a dozen manufacturer lines, and in East Palo Alto we find ourselves reaching for PGT and CGI most often for bay-side homes, where impact-rated glass and corrosion-resistant hardware earn their keep. We also set Ply Gem and Milgard units regularly across East Palo Alto, and we keep a tight supply chain to the local supply houses so lead times do not drag. What matters is that we quote brands side by side, on paper, with warranty durations stated, so you never buy a name you do not understand. Both warranty layers get registered in writing before our truck leaves the driveway.
Common Window Replacement Problems We See in East Palo Alto Homes
- Racked rough openings from Bay-fill settling: Weeks and University Avenue homes built on fill have headers and sills 1-2 inches out of plumb. A straight swap-out shimmed to a bad frame leaves the new sash binding within months. We square the header first.
- Corroded aluminum sill pans on bay-side blocks: Salt-laden air off the Bay eats through old flashing tape and sill pans faster than inland builders expect. Reusing that corroded metal under a new window means water finds the trim. We replace pans on every bay-side job.
- Failed seals on existing dual-pane units: The marine layer in East Palo Alto drives moisture into aging insulated glass. If the existing unit already fogs, an insert-only quote will not fix the fog. We check every cavity before we recommend an insert.
- Mold on interior sills from morning condensation: Single-pane originals on the shaded side of a 1950s bungalow sweat every morning. That moisture feeds mold into old wood returns. Storm units and dual-pane Low-E upgrades stop the cycle.

FAQs - Window Replacement in East Palo Alto
Because so much of East Palo Alto sits on Bay fill. The fill compacts unevenly over decades, and the rough openings in 1950s ranches and bungalows settle 1-2 inches out of plumb. A new sash set into a racked frame will bind within a season. We correct headers and jambs first, then set the window square. That frame labor is part of our written quote, so you see it before you sign. Call (888) 635-0804 and we will check the openings on your block.
Yes. Weeks sits on the Bay edge and gets persistent salt-laden marine air. Aluminum frames and sill pans corrode faster there than even a few blocks inland, and the morning fog cycle is more aggressive on single-pane glass. We spec corrosion-rated sill pans, stainless hardware, and dual-pane Low-E glass with argon for Weeks homes more often than we do for a downtown Palo Alto property with a different exposure. The geography changes the spec.
Yes, but you will need full frame replacement, not inserts. A new Low-E insert set into a corroded aluminum frame will still leak air and water around the perimeter. We pull the old frame, square the rough opening, set the new energy-efficient unit, and flash it correctly. That is how the energy rating actually performs in the real world of East Palo Alto’s salt air and settling soil. Call us for a line-item quote and we will show you the difference on paper.
It means the seal on the insulated glass unit has failed. Argon or krypton gas has leaked out, and the cavity now holds ordinary moist air that condenses when the temperature swings. No cleaning fixes it. The unit must be replaced. In East Palo Alto, where the marine layer drives constant moisture against glass, seal failures are more common than inland. We check every existing unit for fog and seal failure before we recommend inserts, so you do not pay for a new sash over a dead cavity.
After. Repiping and rewiring in a 1950s ranch means opening walls, and that work can knock a new window out of alignment, scuff trim, or force us back to re-flash. Do the invasive mechanical work first, then set the windows. If you are on a tight timeline, we can coordinate with your plumber and electrician, but the window crew should be last in. We will hold your opening measurements and schedule around your other trades.
On a 1954 Ranch off Weeks Street
Every bedroom double-hung was racked hard in frame. The original aluminum sashes had been chewed by Bay salt for seventy years, and the rough openings were so far out of plumb we had to reframe two jambs before flashing tape would lay flat. We pulled the failed single-pane units, squared the headers, set fusion-welded ViewLux inserts with argon fill and low-E glass, and the client’s sill mold did not come back that winter. That is the difference between quoting East Palo Alto as if it were anywhere else, and quoting it like a tradesperson who has actually pulled the trim off a Weeks Street window.
