  • I’m a second time customer with Window Source. I got my first window replacement in 2020 regarding two windows, one of which was very badly rotted. That job was affordable and quick, so of course I return to have windows replaced in my son’s room. My house was built in 1998 and most of the windows are original to the house. My son’s room was the coldest room in the house, and the only possible draft was coming from the windows. Again, the replacement was affordable and fast, and the quality is excellent. I just walked into my son’s room this morning on the coldest day of the year and it is now the warmest of every room! I cannot wait to schedule my remaining windows with the Window Source. There’s a lot of windows that need replacing, and so long as my experience continues to be excellent, I’ll be a returning customer.

  • Eric and Robert were my installers. The contacted me when they were on the way and arrived when they told me they would. Their work was professional and they tidied up when they were finished. They even gave me a little tutorial on how to use the foot-lock. The door looks wonderful!

  • The Window Source technicians were very professional. The guys showed up on time and did a great job with installation. They cleaned up inside the house as well as outside. We were very happy with this service.
