After 8 years I found a defect in one of my windows. I called John and explained the issue. Without hesitation he asked a few questions and order me a new window at no cost. Excellent customer service. Thank You Best Windows.![]()

I recently had Best Windows replace the picture window in my bay window, and I couldn't be happier with the experience. The installation team arrived promptly and worked efficiently, completing the job in a timely manner despite chilly weather. They were also very professional and respectful of my home, ensuring all debris was cleaned up thoroughly afterwards. The new window looks fantastic, and I'm extremely pleased with the quality of both the product and the installation. I highly recommend Best Windows for anyone considering window replacement.![]()

Ruth BaileyTrustindex verifies that the original source of the review is Google.
I used Best Windows in our old house and was incredibly satisfied with the quality of the windows and the service to quote, measure, and install. We moved 3 years ago and have selected Best Windows again for the house we now live in which was build in the 70's. The windows are great, the installers are amazingly quick, super clean, polite and professional, and the follow up by Steve when I had a small follow up was fantastic! We love this company and highly recommend. Thanks, John!!!![]()

John was very helpful. He made suggestions to get the best value. His price is straightforward and very competitive. No nonsense. The windows seem to be good quality. Time will tell. The installers were professional and efficient. Everything looks good and passed inspection with no questions. Overall, highly recommended.![]()

John helped my wife and me find a reasonably priced solution for the replacement of original single-pane windows in our three seasons room several years ago. He also stands behind the product and has replaced a window through warranty even years after installation (gas flush seal failed). Would recommend for anyone planning a window project.![]()

Best Windows does an excellent job installing and serving their windows. A real professional outfit. I have had Best replace windows in my home at various times. The oldest were done in 2008, and these windows still perform as if they were new.

Modern bay windows, especially those we offer at Best Windows Inc., are designed with energy efficiency in mind. They often feature insulated glass, low-E coatings, and airtight frames to help minimize heat transfer, reduce drafts, and lower your energy bills. We can discuss the specific energy-efficient options available and help you choose a window that meets your energy-saving goals.
Generally, bay windows require minimal maintenance. Regular cleaning of the glass and frames with mild soap and water is usually sufficient to keep them looking their best. It's also a good practice to periodically inspect the window for any signs of wear or damage and address them promptly to ensure the longevity and optimal performance of your bay window.
