Hired Tim for a small eavestrough cover installation job. Roof leaked the next day after a windy/rainy night. Tim was able to pinpoint the problem over the phone and came right away to fix it. The leak came from the siding of the dormer. The repair was fast, good and cheap. A couple hundred dollars repair got us through the last 3 years with no recurring leak at all. Hired Tim again to fix a basement leak in my parents's house. Again, Tim showed great knowledge in diagnosing the source of leak and was able provide a reasonable cost yet effective solution. Will recommend him to anyone who does not want to get rip off.
