Courteous, professional and very experienced!  Josh and Leo worked very well as a team to properly diagnose my septic problems and subsequently correct them quickly and effectively.  I had to change two pumps, the floats and also replaced the cement lid.  They also checked the check valves and told me that it wasn't necessary to change them at this time.  So, based on the overall responsiveness and professionalism of this crew, I would highly recommend Great Falls Septic for this type of work.

I just got a team of 2 guys come and service my septic tank that started to back up this afternoon. Within 30 minutes of calling the company they were here, extremely courteous and polite. Very professional team, I spoke to Zach and he explained the issue.

Not disappointed with them at all. I would highly recommend the company.  We are up and running like normal again.  Thanks Great Falls Septic.  We will be using you again


I have called them twice for what I thought were septic problems - and both times they talked me through several steps of troubleshooting, once helping me fix the issue without them coming out, and the second time helping me identify the problem without them coming. Neither time was I given a bill. This for me is a high level of professionalism and customer service - which I really appreciate. They easily could have sent someone out and charged me for it each time.

"Excellent company! Very handsome young men that are very hard workers completed my job today with ease! I truly couldn't have asked for better. Thank you Great Falls Septic Service! Call you in another 3 years!"


"I called Great Falls Septic Service to come to check my tank, I was backing up, had a strong sewage smell in the basement. With 2 young children, I didn't know what to do, but I called Great Falls Septic, talked to the technician and in an hour they came to my rescue. Thank you so much Great Falls for your prompt response, I will recommend you to all my neighbors and friends."
