New Haven County, Connecticut Customer Reviews

Very easy to work with. The in-house rep gave a great presentation and on the spot quotation. Delivery was on time and installation crew did a great job and cleaned up well. Windows look great and we can already notice the quietness and lack of drafts we had with our old windows. Just in time for winter! I will recommend Window World to anyone looking for home improvement.

Everyone we dealt with at Window World was very nice to work with and knowledgeable about their jobs and product. Treavor was very thorough when explaining the features of their windows and what to expect from the time we placed our order until the windows where installed, and even after in regards to our ‘lifetime warranty’. Alexis was very pleasant and kept us up to date with the installation schedule, and finally the installers, they were both very professional and did a great job. We’re very happy we chose ‘Window World’ for our replacement windows.

A great local business with great windows. Their sale person was the only one who came to my home and gave me a no-obligation quote. No pressure to select windows or down payment on the same day. Their price was very competitive. Most importantly, their window installers were very professional and detailed. They did great work.
