Thumbtack customerMay 2026

Bill was easy to communicate with and highly responsive to both emails and phone calls. He offered a very competitive price that others could not beat, and his team did an amazing job replacing seven windows in our home in just one day. On installation day, the team was professional, efficient, and completed the work to a high standard. They also helped replace damaged trim and wiped down the windows before wrapping up, which we really appreciated. I would highly recommend Bill to anyone looking to replace their windows.

We replaced 9 windows with Bill, and had a very smooth experience from start to finish. It took about 3-4 weeks to order the windows and just one day for install. The guys were very thorough and did an excellent job of sealing everything, as well as cleaning up after themselves. Excellent work! Would recommend.

They helped me to replace the old windows and put the new double pane energy efficient windows. The process is quick and smooth. They are very professional. The price is very reasonable after I compared with other two contractors. I highly recommend efficient energy solutions to everyone.

Changed all windows and patio doors in my house. Bill, Jeff and builders team were all very professional, the estimate was very reasonable and took only 4 weeks. Happy with work!

Our new windows are beautiful and the price and quality of workmanship can't be beat. We shopped around with a lot of window companies and contractors, and Bill's experience and knowledge impressed us. He gave us good advice on what types of windows to choose and gave us a heads-up that the manufacturer's lead time would be long. The whole process was easy despite the manufacturer's delay, and Bill did his best to accommodate us and helped us get our project done on time. I would highly recommend Efficient Energy Solutions for your window needs.
