Each one shows its license number. **✓ means we found the company on the [2026 Licensed Montana Septic Pumpers](https://deq.mt.gov/files/Land/SolidWaste/Documents/pumpers/2026%20licensed%20pumpers%20-%20remediated.pdf),** dated 05-20-2026. ["No match"](https://licensedseptic.com/septic-license-lookup/#no-match) does not mean unlicensed. Names and phone numbers on a state list often differ from the ones in ads. Ask for the license number. **Before you call.** Ask for the total price and which fees can be added: digging up or opening the lid, extra sludge, a trip charge. Ask if they pump every compartment through the main lid and check the baffles. Ask for the license or permit number, then compare it to the one on this page. If the pumper says you need a repair, get three written quotes before you agree. ## License records in Yellowstone County ### [Cotter's Sewer, Septic and Portable Toilet Services](https://licensedseptic.com/septic-pumping/montana/laurel/cotters-sewer-septic-and-portable-toilet-services/) 1750 E 8TH St, Laurel, MT 59044 ✓ Montana license S-1087 [Call (406) 628-5989](tel:+14066285989) [Website](http://cotterssewer.com/) ### [Tlc - Patriot Septic And Excavation](https://licensedseptic.com/septic-pumping/montana/billings/tlc-patriot-septic-and-excavation/) 8937 Sundance Dr, Billings, MT 59101 ✓ Montana license S-1151 [Call (406) 633-4333](tel:+14066334333) [Website](http://www.tlcpatriotservicesmt.com/) ### [Brenda Frank Septic Service](https://licensedseptic.com/septic-pumping/montana/laurel/brenda-frank-septic-service/) 1009 Shay Rd, Laurel, MT 59044 ✓ Montana license S-1150 [Call (406) 628-7316](tel:+14066287316) ### [Andersen Sewer LLC](https://licensedseptic.com/septic-pumping/montana/yellowstone-county/andersen-sewer-llc/) Yellowstone County, MT ✓ Montana license S-1192 ### [Arrow Septic and Sewer Service LLC](https://licensedseptic.com/septic-pumping/montana/yellowstone-county/arrow-septic-and-sewer-service-llc/) Yellowstone County, MT ✓ Montana license S-1124 ### [Billings Construction Supply, Inc](https://licensedseptic.com/septic-pumping/montana/yellowstone-county/billings-construction-supply-inc/) Yellowstone County, MT ✓ Montana license S-749 ### [Bogy Inc](https://licensedseptic.com/septic-pumping/montana/yellowstone-county/bogy-inc/) Yellowstone County, MT ✓ Montana license S-1062 ### [C Bar J Mechanical](https://licensedseptic.com/septic-pumping/montana/yellowstone-county/c-bar-j-mechanical/) Yellowstone County, MT ✓ Montana license S-1126 ### [Kernow Inc](https://licensedseptic.com/septic-pumping/montana/yellowstone-county/kernow-inc/) Yellowstone County, MT ✓ Montana license S-1212 ### [Pace](https://licensedseptic.com/septic-pumping/montana/yellowstone-county/pace/) Yellowstone County, MT ✓ Montana license S-996 ### [Portable Restroom Service LLC](https://licensedseptic.com/septic-pumping/montana/yellowstone-county/portable-restroom-service-llc/) Yellowstone County, MT ✓ Montana license S-1119 ### [Tru Pipe Inc](https://licensedseptic.com/septic-pumping/montana/yellowstone-county/tru-pipe-inc/) Yellowstone County, MT ✓ Montana license S-1139 ### [Wells Built Homes Inc](https://licensedseptic.com/septic-pumping/montana/yellowstone-county/wells-built-homes-inc/) Yellowstone County, MT ✓ Montana license S-1155 Order: companies matched to a state list first, then listings with more complete data (phone, website, street address), then by name.
