"Eddie did a fantastic job. He was able to come earlier, which helped me out. He explained what he was doing and got to work. One drain was a particularly hard job, but he kept at it until it worked perfectly. There were no hidden charges or attempts to jack up the cost. When he finished, he cleaned up completely. I would definitely recommend him and use him again if we need to."
