I hired Potomac to come out and install a fire sprinkler system. Talk to Gary. The owner took my money will not finish. My job. Be extremely careful using this company and my opinion they cannot be trusted at all, and I will do whatever it takes to get my money back. I guess I will have to take them to court.
