What our Customers are Saying

  • Had all 6 windows and our sliding glass door replaced as retrofits. After several bids Custom Exteriors offered the best product for the best price.

    Roy W., Homeowner, California
  • Several years ago had Anlin dual pane windows installed as retrofits throughout our home. Windows have performed beautifully to this point.

    Jerry R., California
  • I am still pinching myself in awe of generous people like you that go to bat to help a little girl with cancer who needs a safe and warm place to live. As a child, my family did not have the money to heat our house, and of course the windows were single pane.
