What Your Neighbors Are Saying

From start to finish, Window World was a pleasure to work with. The gentleman who came to give us a quote was very thoughrough and knowledgeable. I love that we were given a quote on the spot, and it was very reasonable. The installers were fast and did great quality work, even in the frigid cold. We have only had our new windows for a day, but we are very pleased!

I was very happy with the installation crew and the windows. All messes were cleaned up. Installation guys were courteous and polite. The windows have reduced outside street noise significantly. The windows look good. Eager to get next utility bill to see the savings.

I received estimates from several window companies and was surprised that Window World was the lowest price because of their amazing warranty. (The others only had a 1 year warranty.) The installation went smoothly and everyone was always courteous. They did a great job of cleaning up after themselves. I am in love with my new windows! I would recommend this company again and again.

Very pleased with Window World. We were happy with our consultation with Tom, he is the reason we decided to go with Window World for new windows. Our windows look amazing and the guys who put them in were very thorough in their work. They were dedicated to making sure each window was sealed properly, etc. We will never go to another place to purchase windows in the years to come.
