what our
customers say?

Bismarck-Septic-Excavating came through when our septic system backed up unexpectedly. They arrived quickly, explained everything clearly, and fixed the issue without trying to upsell anything we didn’t need. It’s rare to find a company this honest and reliable. Highly recommend!

Jeanne Lupo

We hired them for a full septic installation on our new property, and the entire experience was smooth from start to finish. The crew was respectful, kept the job site clean, and answered all our questions. Their workmanship shows they really know what they’re doing. Absolutely five stars.

Andrew Palmer

Another company told us we needed a full drain field replacement, but Bismarck Septic & Excavating inspected the system and recommended TerraLift instead. It worked perfectly and saved us a ton of money. Honest recommendations like this are exactly why we’ll always call them first.

Lenny Weber

You can tell this team understands North Dakota soils and septic codes inside and out. They handled our excavation project and septic repair with precision and professionalism. Their experience really shines — I wouldn’t trust anyone else for a job this important.
