After years of dealing with a crappy hot water tank installed by our builder, the tank finally died. I called Mark after he was recommended to me and he was able to get us up and running with a new tank within two days. It would have been sooner but I opted to wait a day to avoid Sunday warehouse costs. Mark showed up on time and was able to install and test our new tank in under two hours. He also got rid of our old tank for us. The new tank works great and is much better quality than our old one. The tank heats water so well you might burn yourself if you're not careful (which is a good thing!). The cost was fair and, in our opinion, money well spent for such a professional install and quality tank. We would highly recommend Mark for any plumbing related task you might have!
