We needed to have our back door replaced and Mario Tavares of Residential Door Systems was recommended to us by another Homestars contractor we used in the past. When Mario came to provide us with the estimate, he was very friendly and clear about the services and the cost. He knew exactly what we were looking for and quoted us a very reasonable price. Once we signed a contract and ordered the door, it took about 2 weeks before the door was ready and Mario was the one that came to install it. After the door was installed, he was not quite happy about the length of the door trim and he came back the next day to replace the trim to make sure it was perfect. In addition to the door install I asked him to replace window calking (not very well done by another contractor) and Mario did that without extra charge. After he finished our door installation, he also droped by my parents house to fix their sliding door. We very pleased with Mario and very satisfied with the work he did. We could see that Mario takes pride in his work and he wants to make sure that his Customers are satified with his work. We would not hesitate to use him for another project and would recommend him to anyone needing to install a door.
