"In needed a 1,000 gallon buried propane tank removed. It had been buried under a flower bed (and next to a 40â  tree) for over 15 years. Dave came, gave me a clear understanding of what he would do, and just as importantly, how he would do it. He laid out the plan for protecting my trees and not damaging my fencing. On â  project dayâ  Dave arrived on time with a great team and executed his plan exactly as he described. By the time they left you couldnâ  t tell they had dug out a hole 20 x 8 x 12. Amazing job. I highly recommend Dave and his team."

"This Company is by far the Best septic service company I have ever dealt with. Susan responded to my call and she was friendly, helpful and accommodating considering I needed the pump out taken care of on the same day, a Saturday. She understood my urgency and made it happen. The gentleman that performed the pump out was excellent. Friendly, polite, professional, and knowledgeable. He took the time to explain the work he had to do. I highly recommend everyone contacting Atlantic & Sewe, Inc. for your septic needs."
