I live in the country with a septic tank for my sewer waste. Toilet and sinks backed up on a weekend when we had guests over for a party. Thankfully we have 2 systems, so we used the facilities in the back of the house. I called Sudden service on a Sunday. They returned my call quickly, Gave me a flat rate estimate of $350.00 and set up the service date. The technician was punctual, driving a clean and nicely kept up service tank truck. He was personable and informative, clean cut and wearing nice respectable work clothes. He performed the required pumping and inspected my septic system. I followed his recommendations and the kitchen and restroom drains work better than before. He looked over the estimate on his paperwork, since my tank was smaller than the standard tank they service he called in to the office and got a reduced rate on my service call! He cleaned up and left the area in great shape.
