Why Berkeley Homeowners Choose TruePane Windows & Doors
The houses in Berkeley don’t take shortcuts, and neither do we. Dale Kessler founded TruePane because he kept seeing the same two failures: installs that were out of true from day one, and warranty paperwork that evaporated the moment something went wrong. So he built the company around a rule that’s still on the whiteboard: if the pane is not true, the job is not done.
That rule matters in Berkeley, where we work in the Claremont and Elmwood neighborhoods as often as we do in Northbrae and the Berkeley Hills. Homeowners here tend to keep their houses for thirty or forty years. They want a window set square the first time, a door that swings clean in February and August, and a company that will still answer the phone in a decade. We’re that company. Every job carries our Done Right Promise, and before the truck leaves your driveway, both manufacturer warranty layers are registered in writing with the durations stated. No arguments later.
Our technicians are background-checked and uniformed. They measure every opening twice. They quote manufacturer lines side by side on paper. And they work in your home the way they’d work in their own mother’s.
Windows & Doors Services We Offer in Berkeley
Window Installation
New construction, remodels, or replacing a single failed unit. We install manufacturer lines including Andersen, Pella, Marvin, and Milgard, and we’ll show you the actual quote sheets so you can compare glass packages and warranty terms before you spend a dollar.
Learn more about our Window Installation in Berkeley.
Door Installation
Entry doors, interior doors, and everything that swings, seals, and locks. In Berkeley’s hills, we routinely see doors that bind because the Hayward Fault has been quietly shifting the frame for years, not because the hinge screws were loose.

Window Replacement
If your wood sashes are rotted at the sill or the glazing putty crumbles when you touch it, replacement usually beats repair. We handle the full job, from removing the old unit to hauling away the debris, with permits pulled and inspections passed.

Impact Windows & Doors
For hillside homes exposed to wind-driven rain and for homeowners who want serious protection, we install Impact Windows & Doors - Berkeley systems from PGT and CGI. These are engineered, tested units, not standard glass with a heavier frame.
Energy-Efficient Windows
Berkeley’s building stock runs old, and so do most of its windows. Energy-Efficient Windows - Berkeley with Low-E coatings and insulated glazing cut the chill that sits in flatlands living rooms on foggy mornings and reduce the afternoon heat gain on west-facing hills walls.
Sliding & Patio Doors
We install and replace Sliding & Patio Doors in Berkeley and French doors, and we deal with the Berkeley-specific reality of marine air corroding tracks and rollers. If your patio door takes two hands and a knee to move, it’s time.
Glass Railing Systems
For decks, balconies, and stairways, we frame and install Glass Railing Systems in Berkeley that meet California code and actually hold their finish in coastal air. ES Windows and CWS lines are available here.
Custom Windows & Doors
Odd sizes, period proportions, or a homeowner who wants a specific wood species. We order custom units to the inch and set them with the same care as stock sizes. If it’s a historic replica in the Berkeley hills, we know the approval process.
Neighborhoods We Serve in Berkeley
We work throughout Berkeley, from the flatlands to the ridgeline. Typical response time for an estimate is same week, and repairs are often completed in a single visit.

Why Berkeley’s Climate & Housing Affect Windows & Doors
Berkeley’s marine layer does not just fog the Golden Gate. It pushes low, persistent moisture into wood window frames and exterior door sills, especially in the flatlands where the bay air settles thickest. The daily swing between a cool gray morning and a warmer afternoon makes wood expand and contract, which breaks down glazing putty and paint faster than you’d see in Walnut Creek or Concord. We see sashes painted shut, sills gone soft, and doors that swell into their jambs every winter.
Then there’s the housing stock itself. The 1923 Berkeley fire destroyed much of the hills, and what rose in its place was a dense layer of Craftsman bungalows, Tudor Revivals, and Mediterranean homes, most of them still holding their original single-pane wood windows a century later. Replacing those windows means satisfying two masters at once: Berkeley’s Landmark Preservation Ordinance, which protects historic character, and California’s Title 24 energy code, which demands real efficiency numbers. Contractors from Oakland or Richmond do not face this dual burden at the same scale, and it shows in the work when they try.
One more Berkeley-specific fact worth knowing: the Hayward Fault runs directly through this city. It produces aseismic creep, which is slow, continuous movement that never makes the news because there’s no earthquake. But it racks door frames in hillside homes over years. A door that binds at the top corner or gaps at the latch side may not be settling at all. It may have been quietly shifted by the fault. Our technicians know how to diagnose the difference between creep and moisture, and how to plane and reset a door so it works again.
Pricing for Windows & Doors in Berkeley
Honest numbers, because you deserve them before you call. A standard bedroom window replacement in Berkeley typically runs $600 to $1,200 installed, depending on size and glass package. Entry door installation starts around $900 and climbs with material choice. Energy-efficient retrofits for a whole house usually land between $12,000 and $35,000. Impact windows run higher, often $1,400 to $2,800 per opening. Every quote we give is line-item, in writing, and the price on the paper is the price on the bill. We also offer a free written repair estimate, a maintenance check, and a permanent 5% discount for seniors and veterans.

FAQs About Windows & Doors in Berkeley
Most Berkeley homes spend between $600 and $1,200 per standard window, with historic or custom work running higher. Your exact price depends on size, glass package, and whether the opening needs structural repair, which is common in century-old homes. Call (888) 635-0804 for a free written estimate.
Yes, in most cases. Berkeley requires permits for window and door replacements, and historic properties in designated districts carry additional review under the Landmark Preservation Ordinance. We pull the permits and handle the inspections, so you don’t have to.
If the sashes are rotted, the glass is single-pane, or the frames no longer seal, replacement usually costs less over time than repeated repairs. If the issue is just failed putty or a broken sash cord, repair may be enough. We’ll tell you which is which, without steering you toward the more expensive option.
In the flatlands, it’s usually moisture swelling the wood. In the hills, it may be Hayward Fault creep shifting the frame. Either way, we can diagnose the cause and plane or reset the door so it swings clean. Call (888) 635-0804 to schedule a look.
No. We quote fixed prices in writing, and we don’t add change orders unless you ask for additional work. The price on the estimate is the price on the bill. That’s a square deal and we stand behind it.

What Berkeley Customers Say
"A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G."French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."
- Marie S."Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A.
