What a joy to receive more than you expect! I thought we were just having our water heaters drained, and we received a complete plumbing inspection along with the work on the water heaters. It is nice that Abacus is looking to find a problem while it is still small before it turns into a large (and costly) repair. Our technician, Levi, was professional and pleasant to work with. I would not hesitate to recommend Abacus to my friends.
