Best rated replacement window company in Irvine according to Shopper Approved and Google Places!

  • Window source installed 2 new sliding patio doors for me. Work went very smooth and the installers were very good. Price was definitely fair compared to some of the other window companies ive seen

  • Big difference in my home with the new windows. Doesnt get nearly as hot when the sun is blaring and lately with the rain has kept my home warm for longer when i have the heat on. It doesnt need to run all night like it used to!

  • Fantastic Company and true to their word! The crew was so professional and polite. We had our entire house of windows done and it only took 2 days. The quality of these windows are amazing and we couldn’t be happier! Don’t pay the high price that other companies want. This is the real deal!

    Cheryl Cruz
  • Great customer service from everyone at this company including the salesman, installation crew, office manager and owner. Very impressed with the process from start to finish. We had 14 windows replaced and they look great. Very impressed with the installation crew.

    Carolyn Meyers
  • Worked with both Ben and Tom at the Window Source. Both were the most professional of any of the companies that we had to come out. Found them to be straight shooters, and their price was fantastic as well. Really pumped on the new windows and sliding glass door. If you're in the market for new windows you would be foolish to not have them come by for a quote. I'll definitely be referring them to my neighbors.
