AfterFast, Reliable Custom Windows & Doors Across Berkeley
Custom window and door work in Berkeley rarely starts with the glass. It starts with a house that’s been standing since the 1920s, a frame that’s been moving for decades, and a set of local rules that most installers never mention until the job is already underway. We handle the whole picture: the window, the framing behind it, the permit path, and the paperwork. If you’re in Berkeley and weighing custom replacement windows, architectural grilles, or a door that no longer closes square, call (888) 635-0804 and we’ll walk the job with you before anything gets ordered.
TruePane has worked Berkeley’s hills and flatlands long enough to know that every third job here involves something the homeowner didn’t expect. That’s not a problem, provided it’s priced honestly and explained in plain English before the first sash comes out. Our Custom Windows & Doors crew measures every opening twice, quotes manufacturer lines side by side on paper, and stands behind what we set.
Why TruePane Windows & Doors Is Berkeley’s Preferred Custom Windows & Doors Company
Berkeley homeowners don’t hire the first name on a search page. They ask around, they check whether the company has actually done work in the hills, and they want to know who answers the phone. A live person answers ours every day, at any hour, not a voicemail tree and not a regional call center.
Dale Kessler founded TruePane in 2008 as a second-generation glazier who’d spent enough years watching out-of-true installs and voided warranties to know both could be fixed permanently. That’s the whole reason the company exists. Our technicians are background-checked and uniformed, and they treat a customer’s home the way they’d treat their own mother’s. We’re an authorized installer for more than a dozen manufacturer lines, including, PGT, and CGI, so you get real side-by-side quotes on paper instead of a sales pitch for whatever’s in the warehouse.
In Berkeley specifically, we deal with the Landmark Preservation Ordinance and California’s Title 24 energy code at the same time, on the same house. That combination is less common across the bay and almost unheard of in newer East Bay developments. You want a company that has already fought through both with the city’s planning desk and can tell you, before you spend a dollar, what your house’s historic status actually requires. We can.
Our Custom Windows & Doors Services in Berkeley
Most of our Berkeley work falls into a few categories, and each one plays differently depending on where in the city the house sits.
Custom Shape Windows
Berkeley’s Period Revival and Craftsman homes are full of arched sashes, round attic vents, and trapezoid windows tucked under gables. Big-box replacement stock doesn’t cover these. We order custom shape windows from manufacturers including ES Windows and Marvin, matched to the original opening rather than forced into a squared-off retrofit. On hillside homes from Grizzly Peak to the Claremont corridor, that’s the difference between a window that looks like it belongs and one that reads as a patch.
Architectural Grilles & SDLs
Simulated divided lites, or SDLs, preserve the look of true divided-light sashes while giving you modern sealed glass. For Berkeley homes under landmark review, this is often the compromise that lets a homeowner upgrade to Title 24-compliant glass without losing the historic window pattern the ordinance protects. We quote grille profiles, bar widths, and spacer options from brands like CWS and ECO Window Systems, and we show you samples before the order is cut.
Oversized Glass Panels
The hillside homes rebuilt after the 1923 fire were designed to command views of the bay, and many owners now want to open those sightlines further with large fixed panes or multi-panel sliding doors. Oversized glass in Berkeley carries a specific structural burden: wind exposure on ridgelines, seismic bracing requirements, and tempered-glass code thresholds. We handle the engineering and the permit path, and we order glass sized to the opening, never the other way around.
Commercial Storefront Glazing
Along Shattuck Avenue, Solano Avenue, and Fourth Street, Berkeley’s storefronts take a beating from UV exposure, fog-driven moisture, and the occasional delivery truck. We replace and service aluminum storefront frames, door closers, and glass panels for local businesses, and we schedule work around retail hours so a shop isn’t dark during the day.

Trusted Brands We Service in Berkeley
We install and service windows and doors from more than a dozen manufacturer lines, and for Berkeley jobs we typically quote Marvin, Andersen, Pella, and ES Windows, with CGI and ECO Window Systems coming up often for custom shapes and specialty glass. Because we stock common hardware and balances locally, a Berkeley customer with a failed balancer or a sagging patio door roller usually doesn’t wait on a backordered part from across the country. We keep the parts for what Berkeley houses actually have in them.
Common Custom Windows & Doors Problems We See in Berkeley Homes
- Fogged double-pane glass from seal failure. The marine layer doesn’t just sit on the outside of the glass. Berkeley’s cool, damp mornings accelerate seal degradation, especially on south-facing hillside sashes that heat up every afternoon. Once the argon escapes, the pane fogs from the inside and no amount of cleaning fixes it.
- Rotted sills in flatlands Victorians. Homes from the 1890s through the 1910s in West Berkeley and the flatlands often have original wood sashes sitting directly on decades-old felt paper that disintegrated years ago. Moisture wicks into the jamb, rots the sill, and keeps traveling into the studs. By the time the homeowner sees the damage, the opening needs reframing, not just a sash swap.
- Binding doors from Hayward Fault creep. A hillside door that suddenly drags at the top corner but none of the neighbors felt an earthquake? That’s aseismic creep, the fault moving slowly enough that no seismometer registers a jolt. The frame shifts a few millimeters a year until the door doesn’t latch. We re-square these openings and hang the door to the building’s actual geometry, not the original plan.
- Painted-shut double-hungs that trigger electrical upgrades. In older Berkeley homes, freeing a sash that hasn’t moved in forty years often means discovering knob-and-tube wiring running through the wall cavity. Under Berkeley code, opening that wall for window work can require an electrical upgrade. We flag this risk during the estimate, not after the demo crew has already cut the wall open.
Pricing for Custom Windows & Doors in Berkeley, CA
Custom work means real numbers, not a brochure price. A straightforward custom double-hung replacement in a Berkeley home typically runs $1,100 to $2,400 per opening, installed, depending on frame material, glass package, and whether the existing opening is square enough to accept a standard jamb. Architectural SDL upgrades add $180 to $450 per sash. Custom shape windows, like a round-top Queen Anne or a rake-head trapezoid, run $1,800 to $4,200 per unit because the sash is cut to the opening, not pulled from inventory. Oversized view glass and multi-panel doors with reinforced framing run $6,000 to $14,000 once engineering, crane or lift access, and permit fees are included.
What moves the number in Berkeley: whether the house falls under the Landmark Preservation Ordinance, whether the opening needs reframing, whether knob-and-tube wiring lurks behind the wall, and whether the existing frame has been racked by fault creep. We write any anticipated structural or electrical allowance into the contract before work starts, and if we find something the inspection missed, we stop, price it in writing, and wait for your approval. That’s how a square deal works.
Call (888) 635-0804 for a free estimate. We’ll come to your Berkeley home, measure every opening, and give you a written, line-item price with both warranty layers registered before the truck leaves the driveway.

FAQs - Custom Windows & Doors in Berkeley
The answer depends on whether your property is a designated landmark or in a historic district, and which features the designation specifically protects. Many Berkeley hills Craftsman homes fall under the ordinance, which generally requires preserving the original window pattern, sightlines, and exterior trim character. You can often upgrade to energy-efficient frames with low-E insulated glass, provided the window’s exterior profile and divided-light pattern match the original closely enough. SDLs are frequently accepted as a compatible replacement for true divided light. We review your property’s status with the planning department and tell you exactly what’s required before you order anything. Call (888) 635-0804 and we’ll pull the records.
That’s the Hayward Fault’s aseismic creep. The fault runs directly through Berkeley and moves slowly and continuously, without the jolts people associate with earthquakes. Over years, that movement racks hillside door frames a fraction of an inch, and doors start binding at the top corner or gapping at the latch side. No one feels it because there’s no quake. The fix is to re-square the opening to the building’s actual current geometry, not to keep planing the door edge until there’s nothing left. We see this constantly in hillside Berkeley homes and we fix it by scribing new jamb extensions to match the rack, the way we did on a 1924 Tudor Revival off Grizzly Peak Boulevard where the original double-hung sashes were fogged and the framing behind the trim had crept out of true. Call (888) 635-0804 and we’ll take a look.
It’s normal for houses of a certain age, which describes most of Berkeley’s pre-1940 housing stock. The marine layer drives moisture into wood frames, the daily fog-to-sun cycle expands and contracts the wood, and a hundred years of paint jobs eventually seals the sash in place while the sill rots from underneath. Replacing them triggers a building permit through the city of Berkeley. If the work exposes outdated electrical, like knob-and-tube wiring in the wall cavity, Berkeley code can require an electrical upgrade as part of the same permit. We identify this risk before the first sash comes out and write the allowance into your contract. Call (888) 635-0804 for an exact quote, and we’ll walk the house with you first.
That fog is condensation trapped between the panes, and it means the edge seal has failed and the insulating argon gas has leaked out. It can’t be repaired in place, because the seal is part of the manufactured unit. In some frames, only the glass pack, called an insulated glass unit, needs replacement rather than the entire window. In others, particularly older Berkeley sashes with custom dimensions or landmark-protected profiles, the most practical fix is a new sash or full window that matches the original opening. Either way, the answer is glass replacement, not defogging. Call (888) 635-0804 and we’ll tell you which path makes sense for your house.
Title 24 sets performance standards, not brand requirements. The code specifies maximum U-factor and solar heat gain coefficient values for Berkeley’s climate zone, and any window that meets those numbers qualifies, regardless of manufacturer. Custom shapes can absolutely meet Title 24, provided the glass package, frame material, and sizing are specified correctly. We’ve had arched sashes, trapezoids, and oversized view glass pass Berkeley’s plan check without a problem by ordering the right glazing package. The brand choice is yours, not the code’s. Call (888) 635-0804 and we’ll quote Marvin, Andersen, Pella, ES Windows, or any of our other authorized lines side by side so you can see the actual numbers.
