Had purchased two custom windows to replace block windows in august or 2020. Windows were not installed until feb 2021. During this time I had to call the company for updates on installations as 3 different scheduled installations within this time period were cancelled by them. I only found out about cancellations when I called the day before to confirm installation. After installation, one of the windows is leaking water down my walls every time it rains. Still waiting on someone to come out and fix it a month later. Have had no follow up by window world and I am the one trying to have it resolved. Wish I never used them.
