Middlesex County, Connecticut Customer Reviews

Several years ago we got a sliding patio door installed by Window World. This morning we had our first problem. I called the office who asked me to send pictures of the problem. Minutes later I received a call asking if someone could come within the next hour to fix the issue. Within the hour a technician arrived and within probably twenty minutes the issue was fixed. I would recommend Window World to anyone because not only are we pleased with their products, we now know first hand that they stand behind their products even years later.
We recently purchased windows and siding from Window World and had a wonderful experience. AJ and his team were incredibly knowledgeable, hardworking and efficient. AJ was always available for questions and was with us every step of the way. The windows and siding came out BEAUTIFUL and we get compliments from our neighbors ALL. THE. TIME. Would HIGHLY recommend AJ and his team at Window World to anyone who wants a great experience with high quality work.

I purchased windows from Window World. The whole process from the salesman to the completion of the job was flawless. Brenda did an amazing job keeping me informed and helping me through the installation process. Igor the installer is so polite, professional, neat and is so detail oriented and takes so much pride in his work. The window itself is a superior product and I would highly recommend it to anyone. I’m extremely pleased and happy with the final results.
