Less stars would be given if I could. I would not recommend D&M. I'm pretty sure he wouldn't recommend me either. Not a good experience at all. Items were in worse condition once he left.

Our water heater was 12 years old, past the general service life. We had ridden the last one to failure at the expense of a basement flood and a weekend service call. Dave gave a competitive quote, showed up on time and completed the installation in 2 hrs. He installed a high efficiency Bradford White model and we are back in business with no concern for pending water heater failure. Thanks Dave
