I am sitting at 6 days past my installation date. They did not finish on the first day. They said they should be back the following afternoon, but never showed. They set an appointment for Thursday and never showed. After I had to call to see what was going on they informed it wasn't happening that day, but could be by the next day. We agreed on a time and then they showed up several hours early, when I wasn't home forcing me to reschedule what I needed to get done for the 3rd day that week. Ultimately they didn't finish because of rain. They rescheduled for 9am Sunday (today) and have not showed

I ordered windows in February, finally got the install in July. That was a nightmare the crew that came out left trash behind and caulk on my brick. Needless to say they had to send another crew out here today to fix some issues from the first crew. 2nd crew great, informed at the end of the project we had a balance and I assured him he was wrong.. the balance was to be paid in full before the project even started. I call today and the lady who answered the phone stated yes it shows your balance is paid and I told her what my paper stated from the installers. Come to find out window world was wrong

From start to finish, the experience was great. The salesman Clint was great, understood very quickly what we wanted and walked us right where we needed to be. Then the crew that came out was great and did an outstanding job on the install. Thank you.

Three Window World employees showed up to my 80+ year old, high risk parents house to install windows. All walked right into my parents house without masks. When my Dad asked if they were vaccinated, none were. He had to ask them to wear masks and only one of the three workers put on a mask. It is absolutely unacceptable to send unvaccinated and unmasked individuals into people's homes, especially with the COVID Delta variant surging in our state right now. Shame on you Window World.

We recently had some Anderson doors replaced, both jobs being pretty large. The doors took a long time to manufacture but we were patient knowing Covid times are affecting every single manufacturing business on earth right now. We had some other issues with the process and it could have easily turned very ugly but Window World's excellent customer service rectified every one of them. We now have some amazing patio doors with lifetime warranties. If the quality doesn't hold up, I will update my review but for a few months now we have been very happy customers!
