Here is an updated review from my previous one. I now give 5 stars because the manager contacted me, on a Sunday, and addressed my concerns. He explained their policy regarding billing. He even expressed concern that my plumbing issue would get resolved. I was very pleased with the outcome and the way our conversation ended. If needed, I would recommend their services.

A quick shout out to A.J. Leto & Sons (namely, Steve and Vaughn). We had a major plumbing issue (you have to love the older EJ homes). They did the finest professional work in a timely fashion and I was very happy with the final price. It’s nice to have trades persons that know their “stuff” and not someone who thinks they know what they’re doing, but doesn’t. Thanks again!!!
