Quote Icon I bought a home the summer of 2018. I was having some issues with a couple of the windows in the home. I found out they were made and installed by Window world. At that point I reached out to them with my concerns and issues. Found out the windows have a life time warranty, I just needed to transfer paperwork to my name and pay a small fee to do so. It took a little bit of back and forth but ultimately they are getting everything taken care of. I’m not always the easiest customer to deal with especially when it comes to something I’m not too familiar with. I’ve had lots of questions and Jeff, Mylan, Doug and James who have all got the “pleasure” of dealing with me, have been more than helpful. I know Jeff probably dreads when he hears my voice in the other end of the phone but I really appreciate all his help in getting everything settled and taken care of!!
Quote Icon Great people to work with!!

Quote Icon Good quality windows for thousands less than the competitors we quoted with. Had a few hiccups with installation, part due to weather, part due to personnel, but overall the lead installer Jeff did a good job and happy with the experience overall.
Quote Icon Highly recommend! Excellent customer service, LOVED sales guy Randy, and the two men who installed the windows did fantastic! Couldn’t be more pleased, my windows and exterior trim look impeccable. I’ve got the nicest windows in my neighborhood now, lol.
Quote Icon We got new windows from Window World 2 yrs ago and it was a great experience. This weekend I was cleaning my windows and the top came unhooked and fell almost losing the whole window the the mechanism got all bent and couldn’t put the window back in. We called and Lynn came out on a Saturday to help us get it back in and ordered the right part! We appreciated it VERY much!! Good customer service!!

Quote Icon Our windows look great! We had to wait an extra week for our patio door but Jeff kept us updated every step of the way which is so important when it comes to service. The installers were very friendly and efficient. You could tell by talking with them that they really know their stuff! We are very pleased with our decision to go with Window World and intend to do more business with them in the future. Thanks for a job well done!

Quote Icon Called for estimate to replace all windows and doors, timely response, Randy quoted and provided competitive bid and education on options. I have decided to accept their proposal and am purchasing. Will write additional review when job is completed. November 12, 2017: Job completed, 14 windows and doors total, all replaced, in on time, and on budget. Great work by the installers! This was a very positive experience for us and we are happy with our choices.
Quote Icon Amazing company, with great employees, and timely service of an outstanding product. I would really recommend Window World to anybody looking at replacing windows or doors. Jeff and Randy went all out in completing my window and door project. Two thumbs up!
