Fast, Reliable Custom Windows & Doors Across East Palo Alto
Custom windows and doors in East Palo Alto start with one question most companies never ask: has the opening stayed true? On the Bay-fill blocks that run through the Weeks neighborhood and along University Avenue, sixty years of uneven settling racks door frames one to two inches out of plumb. A window cut to nominal dimensions and set into that opening will bind within months. We measure before we quote, and we correct before we install.

Why TruePane Windows & Doors Is East Palo Alto’s Preferred Custom Windows & Doors Company
TruePane was built on a rule Dale Kessler keeps on the whiteboard: if the pane is not true, the job is not done. That rule matters more in East Palo Alto than almost anywhere else we work, because the ground itself does not hold still. We have walked hundreds of post-WWII bungalows and ranch homes here, from the Weeks corridor to the blocks off Bay Road, and we know what salt air does to 1950s aluminum tracks and what Bay-fill settling does to rough openings. We do not quote a straight swap-out and hope for the best. We measure every opening twice, note the rack, and write the frame correction into the estimate before you sign.
Our Custom Windows & Doors team has spent years in East Palo Alto’s specific housing stock: small homes on settled ground, original single-pane sashes, and door thresholds that no longer meet the jamb. Reviews from East Palo Alto customers consistently point to the same thing: we showed up when we said, we explained what the opening actually needed, and we put both warranty layers in writing before the truck left the driveway. That is the Keystone Standard, and it is not optional on our jobs.
You will also get a live person on the phone, 24 hours a day. Not a voicemail tree, not a callback form. If you are standing in front of a window that will not lock or a door that will not close, you call (888) 635-0804 and a person answers.
Our Custom Windows & Doors Services in East Palo Alto
Custom Shape Windows
East Palo Alto’s older bungalows and ranches rarely have square openings anymore. Arched tops, angled corners, trapezoids above the door: every one of these needs a template, not a stock unit. We cut custom shapes to the actual opening, not the blueprint, and we build the frame correction into the same visit. A custom arch window in the Weeks neighborhood typically runs $1,400 to $2,800 per unit installed, depending on the glass package and the amount of shimming the header needs.

Architectural Grilles & SDLs
Simulated divided lites, or SDLs, give a 1960s ranch the look of true divided-light windows without the thermal penalty of individual panes. We apply grilles between the glass or to the interior and exterior surfaces, matched to the sightlines of the original windows. In East Palo Alto, where so many homeowners want to preserve the character of a mid-century home while cutting fog and mold on the sills, SDLs on a dual-pane Low-E unit are one of the most common upgrades we install. Expect $180 to $420 per window for the grille package on top of the window cost.

Oversized Glass Panels
A lot of East Palo Alto homes are being renovated for the Silicon Valley rental market, and the current trend is larger glass, fewer mullions, more light. Oversized panels, meaning anything over roughly 40 square feet, require thicker glass, stronger frames, and in a place with Bay-fill settling, a sill pan and header that can take the additional dead load without racking. We have set panels up to 12 feet wide on East Palo Alto renovations, and every one started with a structural check on the rough opening. Oversized panel packages here generally run $4,000 to $9,000 per opening, installed.

Commercial Storefront Glazing
For the storefronts along University Avenue and Bay Road, we handle aluminum storefront systems, glass replacement, and framing that meets current energy codes. Salt air does the same thing to commercial aluminum that it does to residential aluminum, only faster when the frames are exposed to wind off the Bay. We specify marine-grade finishes and stainless hardware on any East Palo Alto storefront job within a quarter mile of the Bay.

Curtain Wall Systems
Larger commercial and mixed-use buildings in East Palo Alto occasionally call for curtain wall systems, where the glass carries the load and the frame is mostly internal. These are engineered jobs, not commodity installs. We have done curtain wall work on Bay-side properties where wind shear and salt spray both factor into every seal and fastener. A curtain wall job in East Palo Alto generally starts around $25,000 for a modest elevation and goes up from there based on glass type, mullion spacing, and wind load calcs.

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 commonly work with PGT, CGI, and Ply Gem. PGT and CGI both make impact-rated lines that hold up to coastal conditions better than standard inland windows, and Ply Gem gives us a strong mid-range vinyl option for homeowners who want a good window without Andersen or Pella pricing. We keep common replacement parts and hardware for these lines in our Bay Area stock, which means an East Palo Alto follow-up does not wait on a factory shipment. Every quote puts the manufacturer lines side by side on paper, with the warranty durations stated, so you see exactly what you are buying.
Common Custom Windows & Doors Problems We See in East Palo Alto Homes
- Racked rough openings from Bay-fill settling. The Weeks corridor and older blocks near the Bay sit on fill that has compacted unevenly for six decades. Door rough openings run one to two inches out of plumb, which means a custom door cut to nominal dimensions will bind on the latch side within a year. We shim the header and rebuild the frame before setting the unit.
- Corroded aluminum window tracks and seized sash locks. Salt-laden marine air off the Bay pits 1940s and 1950s aluminum tracks until the sash will not move. We see units where the lock has welded itself to the rail. The fix is full frame replacement with a marine-grade finish, not a hardware swap.
- Mold on interior sills from single-pane condensation. Morning fog hits cold single-pane glass, condenses, and runs onto the interior sill. After years of that, the sill rots and mold moves into the jamb. A dual-pane Low-E unit with sealed jambs and a back-dam on the sill pan stops the cycle.
- Door thresholds that no longer meet the jamb. When the slab settles and the frame racks, the door leaf drops and the threshold gap opens to daylight. We rebuild the frame, reset the door, and replace the threshold with a sealed, stainless-fastened sill that will not corrode from Bay air.
Pricing for Custom Windows & Doors in East Palo Alto, CA
A custom single window in East Palo Alto, installed with frame correction and coastal-spec hardware, typically runs $1,200 to $3,500. Custom doors run $1,800 to $5,000, depending on size, glass, and the amount of structural work the opening needs. Architectural grilles and SDLs add $180 to $420 per window. Oversized glass panels start around $4,000 per opening and climb with size and wind-load requirements. The price gap between a coastal-spec unit and a cheap inland-spec unit is often $400 to $900 per opening up front. The cheap spec costs more within a decade, because the hardware corrodes and the frame racks and you pay to do the job twice. We give you written, line-item quotes with the frame correction already in the number. Call (888) 635-0804 to schedule a free estimate. We will not change the price once we open the wall.

FAQs - Custom Windows & Doors in East Palo Alto
Because the ground under your house has moved. East Palo Alto’s eastern half sits on Bay fill and marsh soils that have settled unevenly for 60-plus years, and the Weeks neighborhood and University Avenue corridors in particular show rough openings racked one to two inches out of plumb. If a new window or door is set into a racked opening without correcting the header, it will bind on the latch side within months and the warranty will not cover a failure caused by the opening. We true the frame first, then set the unit. Call (888) 635-0804 for a measurement visit and a written quote that includes the frame work.
Yes, and it is faster the closer you are to the Bay. Homes near the eastern edge of East Palo Alto and in the Weeks neighborhood get persistent salt-laden marine air that pits aluminum tracks and seizes sash locks within 10 to 15 years on windows that should last 30. We have pulled units where the lock had welded itself to the rail and the sash would not move at all. The only lasting fix is full frame replacement with a marine-grade finish and stainless hardware. Call (888) 635-0804 and we will tell you honestly whether yours can be saved or needs to go.
Typically $400 to $900 per opening. That covers the marine-grade frame finish, stainless fasteners, sealed jambs, a back-dam on the sill pan, and sometimes a heavier glass package for wind load. The cheap inland spec will look fine for a few years, then the hardware starts to pit, the seal fails at the mull joints, and the frame flexes when the slab settles. Replacing it within a decade costs more than the coastal spec would have cost the first time. Call (888) 635-0804 for an exact, line-item quote.
You can, but on many East Palo Alto lots you should not, and here is why. A standard Andersen or Pella unit is built to a true rectangle. If your rough opening has racked because the Bay fill under your house settled, the unit will be forced into a shape it was not designed to hold. The frame flexes, the glass seal fails, and the sash binds. We are an authorized Andersen and Pella installer, and on East Palo Alto jobs we still measure the rack before we order or set anything. When correction is needed, it goes in the quote up front. Call (888) 635-0804 for a measurement visit.
Because the moisture is not coming from outside. It is condensation. Your single-pane glass gets cold overnight when the Bay fog rolls in, warm indoor air hits that cold surface, and water droplets run onto the sill. Sealing the exterior does nothing for that. The fix is a dual-pane Low-E unit, along with sealed jambs and a sill pan with a back-dam to catch whatever does condense and drain it outside instead of into the wood. We see this on original windows throughout East Palo Alto’s 1940s and 1950s housing stock. Call (888) 635-0804 to schedule an estimate.
