Quote Icon

Worked with Jeff Barnes initially. Jeff took his time explaining and showing us the different options in our price range and went through pricing multiple times with different options we chose so we got the door we wanted for a price we were willing to pay, and he wasn’t a pushy salesmen! He gave us his honest opinion and explained everything thoroughly. We received two other quotes and Window World was thousands below the other quotes. On installation day, John F. arrived on time and was respectable and personable. He went above and beyond installing our door, and even fixed things he noticed were wrong/missing during installation. His craftsmen-ship, and treating our home like it was his own was exceptional! We are extremely pleased with our service and have already recommended Window World to our family! You aren’t just another sale, or number at Window World. You are treated like family. Best of luck with retirement John, you certainly deserve it!
