What Our Customers Are Saying
"The installers were so efficient, friendly, professional, and skilled in their work. They were careful and cleaned up. The office personnel & salesman were very good to work with & friendly. Since I had no idea what I would be getting into I only had a few windows done, but have since scheduled to have more done & probably doors, too."
- Julia A.
"Excellent experience from start to finish. We got 15 new windows for the house, new mantels, and new shutters. This was the only company to give an itemized list of what things costs so we knew how our money was being spent. Everyone was professional and on time. We greatly appreciate the honesty and integrity. I would highly recommend them to anyone!"
- Tessa V.
"My windows look incredible. The installers were extremely professional and polite. They were careful to not damage my trim around the windows during the install. I was extremely impressed with their cleanup as well."
- Jennifer S.
"Window World’s salesman was very pleasant, patient, and about the customer. He didn’t try to sell me something I didn’t want, he was about getting me the windows that I wanted. The installers were very efficient and clean. They had my windows installed in a few hours when I expected it to take all day!! They cleaned up as they went so you couldn’t even tell they were here. Thank You Window World for making this project so easy!!"
- Cheryl D.
