Customer Reviews
Andrea Spears
Absolutely the best home reno experience my husband and I have ever had! Cant wait to replace more windows in the future! VERY professional. Left no mess. Johns finish work was impeccable. THANK YOU WINDOW WORLD! We will see you again
Glenda Lyon
I have used Window World several times. Their products are superior and their employees are much better. We just had a patio door installed from our living room to our enclosed sunroom. It changed everything for us. With a sleeper sofa, it turned the room into a 4th bedroom for guest and the door provides privacy and a noise barrier.
Nancy Dudrick
Window world came out measured and placed an order. They arrived quicker than originally estimated. Super easy installation and entire window sill outside was wrapped with coil stock. The installers were careful with the plants in the flowerbeds below the windows. Super happy with entire process.

110% satisfied with the job done by window world and there installation team. The crew arrived slightly ahead of scheduled time, after introductions they immediately started working. Within 4 hours all of the old windows had been removed and the new one in place. We also had 3 entry and 1 sliding patio door replaced. By the time they left day one the job was 75% completed, returned the next day finished. All old windows and scrap from new was picked up and hauled off. Except for the new look and yard sign you can't tell they have been here.
The crew was, friendly, professional, well organized and very proficient at their jobs.
I have zero hesitation about referrals for window world. They did what said they would. The quality and craftsmanship is excellent. It is a shame you can only rate up to a 5.
Window world was not the cheapest nor the most expensive, they fell in the middle of the price range, very happy with the final product.
Thank you for an excellent customer experience from the beginning to the end.
