First wrote: Dave is very capable and conveys the sense that he knows just what he is doing. Then, he proves it by doing the job correctly! Dave responded quickly to a referral from a friend, explained what he would do and waited until we were ready to have the work done. And, he is happy to explain what he is doing and why he is doing the way he is! I learned a lot in the process. Recent experience: I had to re-install the heat vents myself. When I called to get help removing the galvanized pipe from under the crawl space I received no response.
