I have an Ashton Woods home that after 5 years needed a window adjustment. I knew XO had adjusted my windows under warranty but was hoping this was something I might do myself (and save a few bucks). Stopped by the XO office and they took time to explain to me how the window was constructed and how I could make the needed adjustment. Thanks to their help, I was able to make the adjustment in about 15 minutes and it works perfect.
