Frank did a great job of troubleshooting a problem with my septic. He is knowledgeable, experienced, and I like the way he communicates. He takes the time to explain what he’s doing and why, and listens to the customer. He was thorough and took a logical step by step approach to properly diagnose the problem without making assumptions or taking shortcuts. I also like the fact that he did not try to add unnecessary services and stayed focused on the issue. His apprentice was very skilled and professional as well. I will definitely be using them again if I have future needs. Wish I would have called them first..
