Window World Came Out On Top!

After calling several companies for pricing and information, Window World came out on top. The quality of the windows had a lot to do with our decision and the fact that the windows come with a life-time guarantee was a major plus. I wanted to commend Window World for choosing to work with the installation team headed by Justin and Tyler; they and their team were always punctual, professional, courteous, and kept a clean workplace throughout the entire install process. There was snow in the forecast throughout the install process and these guys were really good about keeping us updated on when they would by to work on the windows.

Most importantly, I was truly impressed with the quality installation and the wrapping/caulking of each window. As I walked around the house each evening to inspect their work I was astonished at the craftsmanship of the exterior work, given the cold temperatures and snow they had to deal with. Having the windows in place for about a month, we’re really happy with the overall look and efficiency of our Window World windows.

So Pleased With The Window World Experience!

I’ve been building homes for 35 years and have never been so pleased with the crew and products I received. Justin and Tyler never took a break and when they left it looked like they had never been there. The salesman Mike was very knowledgeable and even took the time to stop out while the windows were being installed to make sure everything went well. I really couldn’t have had a better experience.

Extremely Satisfied With Window World!

Christine was very professional and the installers finished the job faster than expected. We had heard about Window World from many different sources but the fact that they donate to St. Jude’s was definitely a deciding factor. We are extremely satisfied, the windows are wonderful and we will definitely refer to anyone.
