Radon Mitigation Cost Factors
The biggest cost factors for radon mitigation in Baltimore, Maryland, include the type of removal method and the size of your home.
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:
| Method | Cost Range in Baltimore, MD | Description |
|---|---|---|
| Sealing the basement | $400–$4,600 | Half as effective; may require repeated resealing |
| Active suction soil depressurization | $1,000–$3,000 | Most common method: PVC pipe suctions gas from beneath foundation |
| Passive depressurization | $500–$2,500 | Vents radon through PVC piping using pressure differences; low efficiency at high levels |
| Wall-based systems | $500–$3,000 | Cinder block wall creates vented cavity to exhaust radon |
| Ventilation systems | $1,300–$2,500 | Two fans remove radon and vent it outside |
| Water mitigation | $775–$4,700 | Uses carbon and aeration to remove radon from water |
Cost by Home Size
The average home size in Baltimore is 1,800 square feet, according to the Federal Reserve Bank of St. Louis’s (FRED) housing inventory. For the average radon mitigation cost of $900, you’ll be paying $0.50 per square foot. Here’s a breakdown of the average cost by home size in Baltimore:
| Home Size (Square Feet) | Average Cost |

Radon Mitigation Pro Costs
The cost to hire a radon detection and reduction specialist in Baltimore varies by the removal method, contractor, and project scope. Since most radon remediation projects take four to six hours to finish, pros charge between $150 and $225 per hour on average.
Licensing
If you’re wondering who installs radon mitigation systems, the best way to find a professional is to look at their credentials. Baltimore does not require pros to possess certifications for radon services, but the city recommends that pros get nationally recognized certifications through the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB).
Permits
Baltimore may require permits for radon mitigation. The cost for permits depends on the mitigation method, so contact Baltimore County to get up-to-date information on which permits you’ll need for the project.
Safety Warning
Exposure to radon over a long period of time can cause serious health problems, including lung cancer. Lowering radon in your home requires professional knowledge and skills only available by hiring a radon mitigation pro.
Taxes
Baltimore does not have a local sales tax, but Maryland has a sales tax of 6.0%. An average $900 radon remediation project has a sales tax of $55.
Additional Pros to Consider Hiring
Radon mitigation projects may require additional professional services in Baltimore that come with their own costs.
Electrician: $50–$100 per hour, for rewiring, radon fan replacement, and installations
Basement finishing: $7–$23 per square foot, for sealing unfinished basements and installing new ventilation systems
Crawl space encapsulation: $2–$10 per square foot, for preventing radon from entering homes through soil and water via crawl spaces
Foundation repair: $1.50–$12 per square foot, for keeping radon from entering your home through cracks

Does a Radon Mitigation System Increase Home Value?
Yes, radon mitigation systems can increase home values in places like Baltimore. According to the Maryland Department of the Environment, every county in Baltimore has reported having high radon levels. By testing your home for radon and implementing radon mitigation steps, you can improve your home’s safety and help it stand out from homes that don’t have a mitigation system in place.
Radon mitigation systems last for an average of 20 years, so be sure to replace your system as it reaches its lifespan to keep your home safe.
