Trusted Berkeley window installers, free in-home quotes, licensed & insured pros, workmanship warranty.
Window replacement in Berkeley is as much a paperwork job as a construction job. Summer highs stop near 73 degrees and almost nobody here runs air conditioning, so you are not buying windows to beat heat. You are buying them to stop drafts, cut fog-season damp, and quiet the street, on a house that may well be protected.
Berkeley's housing is genuinely old and genuinely distinctive. Brown shingle and Craftsman houses fill North Berkeley, Elmwood and the Claremont, plenty of them a century or more old and still carrying their original wood double-hung sash with rope-and-weight counterbalances. Those sashes rattle, stick, leak air around the stiles, and single glazing means condensation runs down the inside of the glass on a foggy morning.
Our crews are in-house and background-checked, and they have worked on century-old Berkeley framing before.
The quote is fixed and itemized, including any custom profile a landmark or historic district requires.
We check your Landmark or Structure of Merit status and handle the Landmarks Preservation Commission process.
Our workmanship is warranted for life, and the manufacturer covers the glass, seals and hardware.
Every style, built for Berkeley's climate.
Two sashes that slide up and down, the correct historical profile for a Berkeley brown shingle or Victorian.
Crank operated on a side hinge, sealing firmly against fog-season damp while still opening wide.
Glides horizontally, a practical choice for a rear addition where the street view is not a factor.
One large fixed pane, worth it where a North Berkeley or Claremont room looks out toward the bay.
Projecting multi-panel windows, a period-appropriate feature on plenty of Elmwood and Craftsman houses.
Awnings hinge at the top and vent through drizzle, and garden windows add a bright shelf for herbs.
For Berkeley's mild, coastal climate we most often install vinyl or fiberglass frames with Low-E 366 spectrally-selective glass.

Berkeley sits in a cool marine zone with mild temperatures and heavy fog influence. Airtightness and condensation control matter far more here than solar rejection or cooling load. This is the assembly we install on Berkeley homes:
| Spec | Recommended for Berkeley | Why |
|---|---|---|
| Glass coating | Low-E 366 spectrally-selective | blocks solar heat, keeps interiors cool |
| Frame material | Vinyl or fiberglass | mild, salty coastal air, corrosion-resistant |
| Gas fill | Argon | better insulation against the heat |
| U-factor target | ≤ 0.28 | exceeds the California Title 24 requirement for your climate zone |
| SHGC target | 0.22 | beats the code cap, and it is what blocks the sun |
In Berkeley the U-factor earns its keep on damp evenings, because warmer inner glass means moisture stays in the air instead of beading on the pane and feeding mildew around the sash. The Low-E coating still handles glare on west-facing rooms with a bay view. Power here runs about 39.7 cents per kilowatt-hour, among the highest rates in the country, so even a mild climate makes a tighter house worth paying for.
Window installation in Berkeley usually runs $600 to $1,000 per installed window, or $12,000 to $22,000 for a full home. Berkeley sits at the upper end of Bay Area pricing for good reasons: century-old openings are rarely square, brown shingle homes often need trim and casing worked around rather than torn off, and landmark properties can require a specific sash profile or true divided lights. Against local home values near $1,300,000, the figure is proportionate, and we quote it fixed and itemized before ordering.

We measure every opening by hand and check your property's landmark status before quoting a price.
Your sash is built to the exact opening, and to an approvable profile if the Commission has a say.
Most Berkeley homes install in a day once approvals are in, and we carry the permit work for you.
We protect the floors, take the old sash away, and register your warranty before we leave.
Berkeley is stricter than almost anywhere else in the Bay Area, and it is worth knowing why before you order windows. A building permit is required for window replacement. On top of that, if your house is a designated City of Berkeley Landmark, a Structure of Merit, or sits inside a designated historic district, the Landmarks Preservation Commission has to approve a Structural Alteration Permit before the building permit can even be considered. That runs through a public hearing, noticed at least ten days ahead and mailed to owners and residents within 300 feet. We check your property's status first, because it changes both the timeline and the window you are allowed to install. Every unit also has to meet California Title 24 at a 0.30 U-factor and a 0.23 SHGC.
"Our place in Elmwood is finally comfortable year-round, the difference was immediate."
"Honest quote, no pressure, and our whole North Berkeley house was done in a day. Spotless cleanup."
"Energy bill dropped noticeably after they replaced our worst windows in Claremont."

Yes, and possibly two approvals. A building permit is always required. If your home is a designated Landmark, a Structure of Merit, or in a historic district, the Landmarks Preservation Commission must approve a Structural Alteration Permit first, through a noticed public hearing.
For Berkeley's cool marine climate, we recommend Low-E 366 glass with argon fill in vinyl or fiberglass frames at a U-factor of 0.28 or lower. Insulation and airtightness matter more here than solar control, because condensation is the local complaint.
Most Berkeley jobs run $600 to $1,000 per installed window, or $12,000 to $22,000 for a full home. Century-old out-of-square openings and landmark sash requirements push toward the top of that range.
Berkeley power runs about 39.7 cents per kilowatt-hour, among the highest rates in the country. On a typical home, efficient windows save about $546 a year on the ENERGY STAR published figure for this climate zone, or about $336 if you are replacing older double pane.
Sometimes, but not with a stock vinyl unit. The Landmarks Preservation Commission reviews exterior alterations on designated properties and cares about sash profile, divided lights and proportions. We establish what is approvable before quoting, so you are not paying for windows the city will reject.
Yes. Every installer we match you with is licensed, bonded and insured in California, and their work carries a lifetime workmanship warranty from your installer alongside the manufacturer's warranty on the windows. We arrange your quote and the introduction; your installation contract is with the installer who does the work.
