These plumbers weren't reliable at all. My dad set up an appointment with them twice and the first time they never came. They gave some lame excuse and sent a guy over the next day. My dad waited took a day off to make sure someone was at home to let them in and the plumber was 2 hours later than he said he was going to be. Then, when he looked at the heater, he couldn't even fix it because he didn't have a part or something. He had to come back a third time and finally repared the damage, but the costs were through the roof. The experience was horrid.
