Dave has done a number of repairs for us over the years, both at our old house as well as at our new home. We have always been happy with his work, his time explaining things, and his willingness to answer the questions of curious toddlers! I appreciated his time and ideas for what could be the problem, and what we could do to fix it. I also appreciated the fact that he took the time to do a minor repair first, rather than immediately suggest we needed the expensive part.
