We are very happy with our windows! We had 15 windows replaced. The guys showed up on time and were very friendly and efficient! They had all 15 windows done, and everything cleaned up, in 4 hours! The windows look awesome!! We can’t stop talking about how much we love our new windows!

Had Window World come out to quote complete windows and 2 sliding glass door replacements. Rich Dugan came out to quote the work. Friendly, courteous & knowledgeable…We could not be more pleased with the installs, the quality and look.

Window World Pittsburgh just finished our siding and boy does it look great! Installers were very professional and meticulous with their work. They patiently addressed any concerns I had and did a top notch job. I highly recommend Window World for both siding and windows. (we got our windows there years ago).

Great experience from beginning to end. I love my Window World windows. The installation crew did a fantastic job. They were professional and respectful of our property. They cleaned-up as they went and then again, thoroughly afterwards. Couldn’t be happier with the job they did and in a timely manner. My windows work great and look great. Thanks Window World!
