Septic Service

They recently completed a job at my site. I contacted Gapter Septic and they promptly responded and started and finished the job in one day two weeks later. I am so thrilled with the professional and knowledgeable service I received I would highly recommend them to anyone needing septic service. An added bonus they are reasonably priced.


Outstanding Business, reputation, and personnel

Great service and work. Originally installed my septic system for my mountain home, installed by this family some 25+ yrs ago. No problems since. They help me with the repair to a leaking water line located between my well and house. They helped excavate and locate a new partial water line that saved me digging up my entire water line and part of my driveway. Great business and superb support. Reasonably priced and well worth your time to check out, investigate and utilize. BTW, Awesome reputation
