I’ve only used them once, but had such a great experience with them, that I wanted to share it with those looking for an outdoor plumber. I am not affiliated in any way. All of the information I have about its business is from what the son told me. He was very polite and courteous and I believe him to be very honest. All locations are owned and run by the same people. Because of this they will drive all over Mobile and outlying areas at no additional charge. First off, know that there is a difference between an outdoor plumber and an indoor plumber. If you need an indoor plumber, I would recommend Cottage Hill Plumbing. Billy’s is — again — outdoor. The business is family owned, which is always a better bet than a corporate place. For me, the son came out. Too bad I cannot remember his name. :(What I liked about him is that he seemed honest and did not try to tell me we needed new lines, which would have been in the thousands. I wouldn’t have known if this were true, so that’s points in his favor. The cost was 10% less than the over-the-phone estimate; the total was $ 225. I called about 11:00 a.m.(and spoke to the mom, who was very sweet) and the son was there by 1:00 p.m. It was quick too. I needed my septic pumped out and it took them only about 1 hour total. The same day service was free. The son was very polite and meticulous(e.g., see ruts below). He also was careful to respect your lawn. For example he did not want to park truck in the yard because he was concerned about leaving ruts in it. He gave me a detailed and informative brochure(which his sister designed), explaining how septics work. My husband always deals with this and naturally, the septic overfilled while he was out of town. So this was good learning material. All in all, based on this one experience, I highly recommend them. Final note: They do accept credit cards, but they charge a fee for their usage. I wrote a check so I don’t remember how much the fee was.
