Replacing a septic tank in Minneapolis, MN, almost always requires permits. Permit costs in the city typically range from $215 to $950, depending on the scope of your project and whether a full system replacement is needed.

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.
Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.

Jeff came out to our house and fixed the air gap in our toilet tank. This company is the best, and Jeff was, once again, superb at his job. He explained what he was going to do, leveled the fill valve and tube to their right heights, and explained to me what had been done. I appreciate...
Last summer someone (not a plumber) installed a new valve apparatus in my toilet tank but it never flushed completely at all times. <br /> That eventually resulted in a clogged toilet. I called Suzanne Boyer, plumber. She checked out the flush, used an auger to unclog the partially clogged...
The job went well. The hourly rate was $160, so to save some money, it made sense for me to drain the 80 gallon tank before Michael the plumber/owner arrived. I ran into some trouble getting the tank's bottom value to release the water out via a garden hose. I called Michael and he told...
The toilet seemed to be flushing with the new supplier line, Todd tested it, we tested it a few times, and then later on that evening the tank stopped filling up and there was no water supply. I contacted Westman Plumbing by email and they responded almost immediately. Todd called us to ask...
Josh came out quickly. He replaced a few parts and thought the problem was solved. Later that night, a part that he replaced came loose and sprayed (lucky for us) fresh water all over the bathroom. The water line was not put in a secure spot so when the tank was filling, it sprayed out from...
