These guys did a good job at short notice. The septic tank was overflowing and backing up into the house. They came and did an assessment for no charge and found that the pump that pumps the effluent up to the drainage field had quit and the drainage field itself was blocked with blackberry roots. He got the tanks pumped out and put in a new pump and dug out and replaced the pipes up to the distribution box and in the drainage field itself. Cost very reasonable compared with other quotes.
