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.

    We had all 13 windows in our home (including 2 custom trapezoids), replaced with brand new Anlin energy efficient windows.

    Great work and went the extra mile to reinstall some blinds.  They took great care and the install went smoothly

    I was not home during the installations, but this is the first time EVER I've come home to hear how the workers were polite and didn't have any rude comments/conversation around my family.

    We purchased our home two years ago which had new windows and a slider installed by the previous owners about 10 years before that.

    Custom Exteriors is a company that I have a lot of confidence in.  Grayeagle was professional and collaborative in helping me with my window planning.
