“Very happy with my windows & this company. The salesman is knowledgeable, candid & helpful. Helped me understand the possible causes of a leak near the window & resolve it. Caused by another company that didn’t do flashing properly! Thanks, Richard! Entire process pleasant & not high pressure. Receptionist pleasant. Installers all professional, quick & helpful. Also showed me previous problem & fixed it. It’s only been a few months but very pleased.”

“Back in 2011 1 of my friends recommended window world to me. So I called them and had 10 windows replaced at that time. And I was very satisfied with their work and the clean up. Then in 2013 I had my French doors replaced with theirs. I love that the blinds were in between the glass. The doors are gorgeous. The people in the office are very friendly and the staff who installs the windows/doors are very friendly. I highly recommend them.”
