We were very satisfied with Koast and his crew. From the time of initial contact for a quote to the final walk through, Koast was timely and professional. Based on the other quotes we received, we feel his quote was fair and right in the ballpark of the others. On the day of install, a large crew showed up on an extremely hot summer day and worked non-stop until the project was done, even through a flash rain storm! Our neighbours were extremely impressed that the crew was able to complete the entire shingle project in a day. They returned the following week to install the gutters, again in a timely fashion. We are very, very pleased with our new roof and gutters!
