How much does window replacement cost in Berkeley?

Window replacement in Berkeley typically costs $300–$1,200 per window installed, depending on size, material, and style. A full-house replacement (10–15 windows) averages $5,000–$15,000. Energy-efficient dual-pane windows qualify for federal tax credits up to $600.

What are the best windows for Berkeley's climate?

For Berkeley's hot summers and mild winters, we recommend dual-pane vinyl or fiberglass windows with Low-E coating and argon gas fill. These reduce heat gain by up to 70% and can lower cooling costs by 15–25%.

How much does window repair cost?

Window repair in Berkeley costs $100–$500 depending on the issue. Broken glass replacement runs $100–$300, seal repair $150–$350, and hardware fixes $75–$200.

Can foggy windows be repaired?

Yes, foggy windows caused by seal failure can often be repaired by replacing the insulated glass unit (IGU) without replacing the entire window frame, saving 50–70% vs full replacement.

How much does new window installation cost?

New window installation with framing costs $500–$2,000 per window in the Berkeley area. This includes structural modifications, framing, flashing, insulation, and interior/exterior trim work.

Do I need a permit for window installation?

In most Berkeley-area municipalities, permits are required when changing the size of a window opening or adding new windows. Replacement of same-size windows typically does not require a permit. We handle all permitting.

Joe was great! Super easy to work with, transparent, knowledgeable, kind, and very skilled. We had a finicky French door out to our patio that had become misaligned/warped due to some settlement. He explained our options and fixed it quickly. Will definitely use again!

Joe is everything you want to find in a contractor: Knowledgeable, Reliable, Honest, Kind, and Professional. I contacted him to help install a kitchen sink for my parents and he immediately responded and scheduled a time to check out the project within the day. Once he arrived, he followed all Covid protocols and walked me through everything that would have to be done. Throughout the explanation, he paused to explain why things needed to be done a certain way and even suggested cost saving options. We discussed payment and timeframe and I contacted him when all the materials arrived. During installation day, he was on time and worked until the project was done. While everything with the sink was done perfectly, there was a slight leak from another unrelated pipe but Joe came back the next day to fix this unintended leak without charge. I would 1000% recommend Joe for any project and look forward to working with him for other projects!

If you live in the East Bay, then Joe is your guy!! He is not only professional and efficient, but also a highly creative problem solver. We were super happy with the variety of fixes he did around our home.
