Fantastic plumber - very knowledgeable and great customer service. Third plumber I had to the house in 12 months. I wouldn't even consider calling the other two back, and I expect to call David Howard back for any other plumbing problems I have. He charges $100/hr plus parts and includes his travel time in the hourly charge, which seems reasonable - others charge a flat travel fee no matter far. The first work I had done was in Nov 2012 on my boiler. I had had another company in to service it and repair a zone valve; I noticed immediately after they left that I was getting a lot less heat. I hadn't been thrilled with them, so I called David based on his Angie's List ratings. He was able to come the next day, and determined that I had a faulty pressure relief valve and that my water feed wasn't working so there was very little water in the system and the pressure was way too high (FYI - very dangerous). The previous plumber noticed the temp and pressure seemed off and replaced the gauge, which didn't fix the problem, but his only other thought was that the aquastat was bad; he didn't realize the other two issues. I had since purchased a replacement aquastat and David agreed to install it even though that isn't actually plumbing work; the boiler ran fine all winter. In June 2013, my sump pump stopped working over a Friday night and I got 3" of water in the basement. I called David Saturday morning; he was over in 30 minutes and rapidly discovered the float was jammed - a very easy fix. He only charged me for 1 hour even though he was here for at least 45 min making sure the pump was going to work and he had had to load a bunch of gear in his truck before he left home. It was OT rates for Saturday, so total cost was $150, which I thought was very reasonable. Bottom line: I recommend him without reservation.
