“Tim and his crew did a fantastic job with the complex installation of my panel system on my new home. Another septic company dropped the ball and Tim and his crew saved the day. They were prompt, courteous, on budget and on time with completion. I highly recommend TW Ammons Septic.”

“Tim was extremely helpful regarding our lift-pump system in our home. We thought the pump was broken, but when I called and spoke to him, he told me how to test to see if it was really broken.
