  • You cannot open these windows with a feather like the commercial states.

  • The men who did the actual installation were very pleasant, knowledgeable, and thorough.

  • Originally had a contract to replace most of our windows with Champion Windows. After the agreed upon price Champion notified us that it would be 1600 more dollars due to the salesperson adding wrong on the estimate. They refused to take responsibility for their mistake so we cancelled the contract and began looking for another company. Ended up going with Window Source to replace the windows. They were able to provide all the same windows, with one additional large picture window for cheaper than Champion. Installation crew showed up on time and were great. They were able to get all 12 windows installed and clean up with no inconvenience to us at all. They were all very professional and did a great job. Very happy with the Windows!

  • Great service. Love my new windows. Had an adjustment issue after installation quickly serviced and taken care of. Highly recommend. Got 2 other estimates but chose Window Source in the end and am glad I did.
