I spent $700 on that work. The job went well. They always send the same person out. They have been here before. Even when we call the office, they know who we are.

We had a leak under stamped concrete patio. They found it with their sound equipment, and pinpointed it within a couple of square feet. We had some laborers jackhammer that area and they found the leak. I highly recommend them. They replaced our septic tank and cleaned in the past.
