Fast, Reliable Custom Windows & Doors Across Piedmont
Custom window and door replacement in Piedmont is a different job than it is almost anywhere else in the East Bay. The city runs its own Design Review process, and that review board looks at every exterior alteration through the lens of architectural preservation. So before you buy a stock unit off a big-box shelf, you need to know whether the divided-light pattern, frame profile, and material will pass. Our crews work inside Piedmont city limits every month. We know what the Board accepts and what it sends back. Call (888) 635-0804 and we’ll walk your project through that review from the first measurement to the final inspection.
Why TruePane Windows & Doors Is Piedmont’s Preferred Custom Windows & Doors Company
Piedmont homeowners tend to research carefully and then decide once. Many of the homes here have been in the same family for thirty or forty years, and the people in them remember a contractor who left a fogged seal or a door that binds in July. We’re the counterweight to that history. Dale Kessler founded TruePane in 2008 on one rule: if the pane is not true, the job is not done. That rule shows up in how we measure, how we order, and how we install.
Our work in Piedmont centers on the 1910s through 1940s housing stock that dominates the city. Craftsman bungalows off Highland Avenue, Tudor Revivals up toward the hills, Colonial Revivals near the Oakland line. These are not cookie-cutter openings. They are hand-built frames with plaster walls, old-growth wood sills, and decades of subtle seismic movement. We send background-checked, uniformed technicians who measure twice and quote manufacturer lines side by side on paper. Most jobs are completed in a single visit, and every job carries the Done Right Promise: if it is not done right, we make it right. No paperwork, no arguing.
Response time to Piedmont runs on a schedule we can actually keep. Scheduling is coordinated from our San Francisco Bay Area office, and crews serve the city locally. A live person answers the phone 24 hours a day, 7 days a week. When you call, you’re talking to someone who owns the result.
Our Custom Windows & Doors Services in Piedmont
Architectural Grilles & SDLs
This is the sub-service that defines Piedmont work. The Design Review Board has rejected simulated-divided-light windows on period homes because applied grilles fail to replicate the sight lines and shadow depth of true divided lights. Contractors working here learn to specify true divided light or authentic wood windows upfront rather than re-bid after a denial. That spec discipline is rarely required just across the city line in Oakland. When a homeowner on Sea View Avenue or near Piedmont Park wants a historically faithful replacement, we walk them through the difference between true divided light, simulated divided light with a shadow bar, and plain applied grilles before a single frame is ordered.
Custom Shape Windows
Piedmont’s older homes often carry feature windows that stock manufacturers no longer catalog. Arched sashes above entry doors, eyebrow dormers on second stories, half-round transoms in stairwells, hexagonal accent windows on gable ends. These openings cannot take an off-the-shelf unit, and forcing one in means ugly infill framing that Design Review will flag. Our Custom Shape Windows service builds each unit to the existing rough opening, matching the original radius, spring line, and sight line. In Piedmont, that often means matching a 1920s leaded-glass transom geometry in modern insulated glass.
Oversized Glass Panels
Many Piedmont homes were built to frame a view, not to meet an energy audit. Living rooms with eleven-foot ceilings and eight-foot window walls are common in the larger hillside properties. Replacing those openings with a single oversized insulated glass unit is a structural decision, not just a cosmetic one. The weight of the glass, the wind load on the hillside exposures, and the deflection of the frame all have to be calculated, not guessed. We quote oversized panels with the structural engineering attached, so the permit package is complete the first time it goes to the city.
Commercial Storefront Glazing
Piedmont is primarily residential, but the few commercial storefronts along Oakland Avenue and Grand Avenue near the city boundary need the same disciplined glazing approach. Storefront work in a city that reviews every exterior alteration requires careful attention to sight lines and frame finishes. We handle commercial storefront glazing, curtain wall systems, and glass railing systems for the property owners whose buildings sit in Piedmont’s limited commercial zones, and we do it with the same line-item, written-quote discipline we use on homes.
Trusted Brands We Service in Piedmont
We are an authorized installer for more than a dozen manufacturer lines, and we quote them side by side on paper so you can see exactly what you are buying. For Piedmont’s older stock, we frequently spec ES Windows for custom true-divided-light double hungs, CWS for period-accurate wood profiles, and ES Windows’ custom shape capabilities when an arched transom needs to match a 1930s original. We keep ordering templates specific to these manufacturers on hand, so a replacement part or a warranty claim does not sit in a queue. Each job includes both manufacturer warranty layers registered in writing before our truck leaves the driveway, with the durations stated.
Common Custom Windows & Doors Problems We See in Piedmont Homes
- Design Review denial on off-the-shelf SDL units. A homeowner or a less familiar contractor orders a standard simulated-divided-light window to meet energy codes. The Board rejects it because the applied grilles look flat and lack shadow depth. The project stalls, and the owner pays for a re-spec. We write Design Review compliance into the contract from the first measurement.
- Out-of-square rough openings from Hayward Fault movement. Piedmont sits near the Hayward Fault, and fifty or eighty years of micro-movement can push a rough opening out of square by half an inch or more. A stock unit dropped into that opening leaves gaps that leak air and fail the seal within the first fog season. We measure every opening twice and cut custom sizing when the numbers tell us to.
- Rot beneath trim on north- and west-facing sills. The marine fog that pushes in through the Diablo Range gaps settles over the East Bay hills where Piedmont sits. Nighttime and morning moisture accelerates rot on the wooden sills facing the fog’s prevailing directions. We back-prime every piece of wood, flash the rough opening, and build a drainage plane that handles this microclimate. Fail to do that, and rot sets in beneath the new trim within two winters.
- Fogged original steel casements. The 1920s Tudor Revivals and Spanish Eclectics up toward the hills often still carry original steel casement windows. The glass fogs between panes as the seal fails, and the steel rusts through at the jambs. Replacement is the only permanent fix, and the replacement has to respect the original thin sight lines. We handle this with custom steel-look or true-divided-light units sized to the existing opening.
Pricing for Custom Windows & Doors in Piedmont, CA
Custom window and door work in Piedmont runs higher than nearby Oakland and Emeryville for a straightforward reason: Design Review compliance and true divided lights cost more than stock SDL units. A typical custom true-divided-light double-hung in Piedmont runs $1,400 to $2,800 per opening installed, depending on frame material, size, and whether we need to rebuild a rotted sill. Custom shape windows, like arched transoms or eyebrow dormers, typically land between $2,200 and $4,500 per unit. Oversized glass panels for hillside view windows run $3,500 to $9,000 installed, including structural review and any framing work. A full-house window replacement on a 1920s Craftsman with true divided lights can run $38,000 to $75,000 depending on opening count and logiistics.
What affects the number: whether the rough opening is square, whether the sill needs rebuild work, whether Design Review requires true divided light, and whether we encounter failed waterproofing once the old window comes out. We write every quote as a line-item allowance before demo starts. If inspection confirms the rough opening needs new flashing or back-priming, you see it and approve it in writing before we touch it.

FAQs - Custom Windows & Doors in Piedmont
Changing the divided-light pattern is one of the most common denial triggers in Piedmont. The Design Review Board evaluates window replacements against the original structure’s architectural character, and that includes the number and proportion of lights. If your 1920s Craftsman has a six-over-one double-hung and you want a plain single-light unit, the Board will likely reject the change. True divided lights matching the original pattern are the safest path, and we quote them as the base spec on period homes. Call (888) 635-0804 for an exact quote on your specific pattern. Estimates are free.
We measure it, write the custom sizing into the allowance, and then we order the unit to that actual opening rather than to the nominal size. On Indian Road, our crew opened up a 1920s Tudor Revival to find the original steel casement windows rusted through at the jamb, with the surrounding plaster-over-lath opening out of square by nearly three-quarters of an inch from decades of Hayward Fault micro-movement. We wrote the custom sizing and true-divided-light upgrade into a line-item allowance before demo, then after inspection confirmed the rough opening needed new flashing tape and back-priming before we set the fusion-welded frame. That is the standard process, not an exception.
We stop, document what we found, and bring you a written line item for the repair before we do anything else. Failed waterproofing behind old windows in Piedmont is common because of the marine fog moisture that settles on north- and west-facing exposures. The fix is straightforward: new flashing tape, back-primed wood, and a proper drainage plane before the new frame goes in. That repair is priced and approved in writing before we continue. Call (888) 635-0804 if you suspect waterproofing issues on your existing windows. The wrong install makes it worse.
Yes. Piedmont requires a building permit for window and door replacement when the work alters the exterior, and the city’s Design Review process applies when the changes affect character-defining features like divided-light patterns or frame materials. We pull the permits, submit the design review package to the city, and handle the inspections. Our quote includes the permit fees. Call (888) 635-0804 and we’ll tell you exactly what your project triggers.
Condensation between the glass means the seal has failed and moisture has entered the air space between the panes. The window’s insulating performance drops, and with a steel frame in Piedmont’s damp marine fog microclimate, rust at the jambs usually follows. Replacement is the permanent fix. We quote custom size and true-sightline steel-look or authentic wood units that match the original opening and pass Design Review. Call (888) 635-0804 for a free estimate on the full opening, not just the glass.
Call (888) 635-0804 today to schedule your free estimate for custom windows and doors in Piedmont. Dale Kessler and the TruePane crew will measure, quote, and stand behind the work. If the pane is not true, the job is not done.
