How Much Does a Radon Mitigation System Cost in Minneapolis? [2026 Data]

Radon mitigation systems in Minneapolis cost an average of $1,367 to install, although homeowners often spend $1,242 to $1,563, depending on the type of system, the size of the house, and, importantly, the home’s age. Minnesota has a high rate of radon exposure in homes, so the state building code requires homes built after 2009 to have passive radon systems. It costs less to install an active system in a newer home that already has a passive system, and it’ll cost more to install a radon mitigation system in older homes.

Radon Mitigation Cost Factors 

Radon mitigation system costs in Minneapolis, MN, depend primarily on the mitigation method and the age of the home, but house size can also influence the project total.

Cost by Method

The cost of a radon mitigation system depends on the chosen approach, which might be sealing the basement, depressurization, or lower-level pressurization. The depressurization method happens in one of two types: active suction (soil depressurization) or passive depressurization. 

Here’s what to expect for pricing by radon mitigation method: 

Cost by Home Size 

Home size can play a role in the cost of radon mitigation. The larger the home, the more materials pros need to build an effective mitigation system, which leads to higher costs. In Minneapolis, the average home is 1,800 square feet, and radon mitigation systems cost $0.55 to $1.05 per square foot of house. Here’s how much you can expect to spend based on home size:

Cost by Home Age

Since June 2009, Minnesota’s building code requires new constructions to have passive radon systems. So, if you choose to upgrade to an active system, the cost will be much lower for homes built in mid-2009 or later.

Radon Mitigation Pro Costs

The state of Minnesota has strict requirements for licensing and building codes regarding radon mitigation because radon leaks are a major concern for houses here. You shouldn’t attempt to DIY a radon mitigation system, especially in Minneapolis, because exposure to this gas can cause cancer. 

Instead, hire a radon testing pro in Minneapolis to test your home and make recommendations for the best radon mitigation system for you.

Labor

In Minneapolis, radon mitigation system installation costs $50 to $150 per hour, per worker for labor. However, you’re not likely to see hourly rates on the bill. Instead, radon mitigation services will provide a project total that’s calculated based on the mitigation method, home size, and building age. Labor rates and permit fees are built into the project total.

Permits

Minneapolis building permit fees start at $84.20, and the pro you hire will handle the permit process for you. You may need to pay for additional permits for an electrician to wire the fan on an active radon mitigation system. 

In addition to work permits, the Minnesota Department of Health requires all professionally installed radon mitigation systems to be tagged. This tag costs $75.

Warranty

Most radon mitigation systems include a five-year warranty on the fan, plus five-year (or up to lifetime) warranties for the system’s overall performance. An extended warranty, which adds another five years, costs $200 to $500. Radon fans last 10 to 15 years, so an extended warranty can save you money on the cost of radon fan replacement in the future. 

Additional Pros to Consider Hiring

A radon testing and mitigation service will be the primary professional to work with for this project, but you may need to hire additional experts to finish installation, seal cracks where radon could be seeping in, and make major updates like repairing and finishing a basement.

• Electrician cost: $180–$620

• Basement finishing cost: $2,800–$100,000

• Foundation repair cost: $1,650–$7,450

Does a Radon Mitigation System Increase Home Value?

Radon exposure is extremely common across Minnesota. Over 40% of homes here are at risk of high radon levels, according to the Minnesota Department of Health.

So, having a radon mitigation system can give potential buyers peace of mind and minimize the risk of a lower selling price you’d see if your home inspection reveals high radon levels. The installation may not increase your home value by a specific dollar amount, but it can ensure a smoother selling process without inspection delays or value losses.
