- CTCynthia Tilghman-LaddOct 16, 20255.0Our church had 13 windows replaced in our Educational wing and Window World did an excellent job. All windows were on the second floor of the building so not an easy job. The workers were all professional and worked tirelessly to complete the job in 3 days. The transformation is amazing! The job was cleaned up when completed and our building has never looked this good. These are new owners and they are doing a great job! Highly recommend!
- ZCZachary CoxSep 9, 20245.0Very impressed with the windows. Fair price, timely install, professional service. If they keep us warm in the winter, I’ll be thrilled.
- MLMarie LogothetisJul 30, 20245.0Window World installed 9 windows in my porch. The process was smooth from start to finish. The installers arrived on time, took out the old screens and installed the new windows. They were respectful of my property, explained every step, cleaned up and finished by the end of the day. I highly recommend Window World and would use them again.
- RHROBERT HortonApr 18, 20245.0I ordered 10 windows from Window World. They came in in around 30 days which was really good and then soon as they came in waited a week for delivery which was really quick because I’ve dealt with other Window World across Southeast and usually you know they were waiting 60 days 90 days for their stuff so I’m really glad it came in very quick. The installers Dom his wife and the other guy I’m sorry I forgot his name but they were so professional cleaned up really didn’t even make that much of a mess to begin with but cleaned up. Left it the same when they got there and my windows you know I had three different style windows on my second floor and he correctly installed the windows. I couldn’t have been more impressed with him. He had a lot of knowledge on windows. I was just impressed with him. He is definitely an asset for your company, but thanks again and I’m actually gonna order more windows from you guys, so I’ll see you at the end of the year again thanks. I will definitely be using you guys to install my windows.
