I have recently found Thompson's Services and it was a great experience from initial contact, to timely service, and fair price. There was also extensive knowledge and professionalism delivered. Much appreciated!
Let's see: Called me back not long after I left a message. Showed up at the appointed time. Super friendly. Got the job done. Will be using going forward!
John arrived punctually and was courteous. Additionally, he provided valuable advice on maintaining the septic tank properly. The service was excellent!
I just had my septic tank pumped by Thompson's. They found the tank cover right away (we only had a vague idea of where it was), and were fast, efficient, friendly, and resonably priced. They also gave good advice about maintaining the system. I will definitely be using them again.
No one answer phone call or return messages.
