Simsbury, Connecticut Customer Reviews

Window World came to my house and installed a basement window, and they did a very nice clean job, I am very satisfied with them. They were very professional and If you have some windows to be done, I would recommend them.

All the workers were polite, friendly, worked hard, cleaned up after they finished, and did a great job. I couldn’t be happier.

James G.

The windows and doors look great and were installed quickly (and cleanly). Thank you to the install team who came out to do the work on such a chilly day! Our heating bill thanks you too.
