Recent Good Review from Bernadette Malec

Hot Water Heater a
My hot water heater was leaking and 21 yrs old. Mary Ellen was very helpful with financial info. Kyle Baxley and Jared Dotson came the same day and in no time a new unit was professionally installed with no mess and the old unit was removed. They were careful to cover their shoes and cleaned up anything they used. I sincerely appreciate the efforts of all involved to get my new hot water heater installed the same day I called.

Disappointment of the first degree.
This company's accounting and customer relation stinks. I love Baltimore and companies doing business in Baltimore, but not this company.
