What Your Neighbors Are Saying

We got 16 new windows and our house is so much more comfortable now. Our heater is not running as much and we are looking forward to a lower heating bill! The installation went quickly even though our house is old and the basement windows did not come out easily. The installers were polite and friendly. We are very pleased with our purchase.

Window World was wonderful to work with! I had a lot of questions when selecting the windows and talked to several employees who were really patient and helpful. The installation was fast and the guys were respectful and cleaned up after themselves. Our new windows look great!!

Good company. Very professional. We had 13 windows and a sliding door installed in one day. They did very neat work and cleaned up the mess as they went through the house. Very well made windows. They showed the wife how the windows and sliding door works and features. They addressed any concerns I had on the spot. Highly recommend these guys.

The entire process from obtaining the estimate until job completion was a great experience. We love our new windows and siding! Randy was very helpful in explaining our options when ordering. Rick and Andrew did a great job installing the windows and siding. The office staff were prompt in contacting us when we had concerns…We would highly recommend Window World!
