Our Window Replacement & Installation Services

We've been working on Bay Area homes since the 1970s, which means we understand old-school construction just as well as today's building codes. That experience matters when you're dealing with older framing, retrofits, or non-standard openings. Homeowners pick us for our attention to detail, tidy installations, and the certainty that the job will be completed on time and to your satisfaction.

Window Replacement

Most of the Walnut Creek homes we work on still have those original aluminum or single-pane windows from the 70s and 80s. These windows have a common issue - the seals fail and you get that foggy look between the panes. Replacing them with double or triple pane windows makes a huge difference in comfort and energy costs. I'll come to your home, measure your windows, and provide you with a free estimate. Most vinyl windows run $300-$800 installed, and we typically finish the job in one day. Every window is properly sealed, caulked, and tested before we leave.

⭐ What Your Walnut Creek Neighbors Say About Us ⭐

Don't just take our word for it. Here's what Walnut Creek homeowners have to say about our window replacement and installation services.

★★★★★

"Tim responded to my text within 30 minutes with a fair quote. We had foggy windows throughout our Northgate home and got three quotes. Tim was the only one who responded same-day and gave us a clear price breakdown - no sales games. His crew arrived on time, protected our hardwood floors, and finished all 12 windows in one day. The installers explained everything they were doing and cleaned up perfectly. Six months later, everything still looks great. This is how contracting should work."

Replaced 12 windows in 1970s ranch home

★★★★★

"After getting burned by a big window company that kept changing prices, working with Tim was refreshing. He measured our windows himself, explained why we didn't need the most expensive option, and stuck to his quote. The installation crew was skilled and respectful - even my nervous dog was comfortable with them. When we had a question about one window seal, Tim came back personally to check it. Turns out it was fine, but he wanted to make sure. You can't buy that kind of service."

"Professional work without the corporate hassle Our 1960s home near Rossmoor needed all new windows - the old aluminum frames were shot. Tim walked us through retrofitting versus full frame replacement and was honest about what we actually needed. His crew was fantastic - clean, efficient, and they fixed some rot they found without nickel-and-diming us. The whole project took two days as promised. My heating bill has already dropped. Highly recommend to anyone tired of contractor games."
