I've used Rickey three times; first was for frozen pipes. Now obviously, when your pipes freeze, there's likely a lot of other people with the same problem, but he showed up within an hour, and had the job done very quickly. It seemed pricey, but I figure I was paying for his expertise, and if the pipe had of burst, he would have been right there. Also, I doubt he was any more expensive than other plumbers.
Second time, I had a problem with the toilet. He came over, told me all I needed a new flapper (he didn't have the right kind on him) and tightened some bolts. Took him 2 minutes. Cost: $0. A lot of plumbers would have charged for the service call.
Third time was today. Another toilet problem. I called him and described it, he thought it was just a blockage and told me if I had a closet auger to try and clear it. I did, it worked, again, $0.
