The gutters and leaf guard are excellent. Not the cheapest, but quality materials and installation cost more. Dave kept me informed and answered my texts promptly. The installers, Orlin and Marcelino, were skilled and easy to work with. Their attention to detail was appreciated. I can highly recommend them.
