After accuracy, honesty and fair dealing with an environmental company where deadlines are key, responsiveness comes second. I always get a phone call back from Sinni Septic Service every time I try to contact them, by the man in charge, Nate, before the end of the day if he is not in the field. He is honest and goes the extra mile to offer realistic expectations. I have been a real pain, a pest, to try and get a job done faster than normal in order to meet a deadline and Sinni Septic Service has been very professional in keeping me informed step by step. In terms of the work - I was told the price was fair and it was done professionally and quickly. Thank you, Nate and the team at Sinni Septic Service. I will happily pass your details to anyone who requires cleaning services.

We called and were able to talk to a technician. He talked with us about the problem and gave us pricing for coming out on Sunday. He told us he would be here in about an hour and a half. And hour and a half later, he showed up. Very courteous and professional he got to work right away. Replaced some of the parts we had "fixed" with better parts without saying anything. He worked for about an hour, checked the system and verified that it was not still leaking and gave us a bio for exactly what he said it would be. Only three days in but no more problems and the fix looked very good quality. Highly recommend this company. We are actually going to have them come back out and fix different problem in the coming weeks.
