When I posted my job on the site, Sean responded straight away and offered to come to my house the next day. He showed up on time the next morning, inspected the roof, and explained to me clearly about what the problem was. Two days later he came and completed the repair work, at a very reasonable price. He was very professional and also helpful, willing to answer any question I had. I was very impressed with his work and would definitely recommend him to others. 10 out of 10!
