I went to New Orleans with Javier from A Plumber, Inc. after Hurricane Katrina to do some volunteer work for victims of the hurricane. In addition to repairing damage, I saw him do some very good replacement work on older houses. He modernized several of their systems to prevent problems that would have occurred soon due to age. It had nothing to do with hurricane damage. He just did it so the place would be right when he left. He even detected and replaced a leaking gas line for a lady who had no means to pay for it. It was very good work and he did it quicker than I thought possible.
Javier does excellent work (my own father is a plumber so I've seen enough plumbing work to know the difference) and does it very efficiently. He's a good plumber and a good person. You can feel comfortable with him on the job. If he fixes something, it will be done right.
