I'd rate him lower than a one star, but sadly that's not allowed. Check him out on BBB if you don't believe our word about him being the worst plumber ever. Here's a link to it directly. https://www.bbb.org/central-texas/business-reviews/plumbers/a-1-plumbing-in-robstown-tx-136651/reviews-and-complaints
On that note, here is my complaint. Long story short, he never calls you and doesn't show up on time. If you call him he'll tell you "I'll call you back, I'm in the middle of something." (You're one of the lucky ones if he actually calls you back.) He shows up with no materials, then leaves again and will be gone for a couple hours. Shows back up with NO materials still then says he's waiting for his helper. When the "helper" and materials finally arrives, he does a crappy job on the work. He leaves the area a mess and doesn't clean up after himself. If you have an animal, I highly encourage you to keep them in a different room because he will hit your animal. He actually hit my dog and claimed to be petting him... Also whatever work he does will have to done again because he didn't do it right the first time. Do yourself a favor and stay away from him.
