We have used Masellis Aluminum for all our window and door replacements in the past on several occasions. My front door was recently changed to a fibreglass door with sidelights. Domenic and Felix advice was helpful in making my final decision as they were patient and courteous with both the order of the front door as well as the installation. As usual the quality of their windows are good. The service received by both Domenic and Felix was great and I would recommend Masellis Aluminum if you need to get new windows or doors.
