The radon mitigation method you choose directly impacts your costs, but your home’s size and age also play a role. Let’s break down these cost factors to help you budget for radon mitigation in the Massachusetts capital.
Radon Mitigation Cost Factors
If you’re getting ready to address a radon problem in Boston, MA, here are the main cost factors to consider.
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 Boston, MA | Description |
|---|---|---|
| Sealing the basement | $407–$4,681 | Half as effective; may require repeated resealing |
| Active suction soil depressurization | $1,018–$3,053 | Most common method; PVC pipe suctions gas from beneath foundation |
| Passive depressurization | $509–$2,544 | Vents radon through PVC piping using pressure differences; low efficiency at high levels |
| Wall-based systems | $509–$3,053 | Cinder block wall creates vented cavity to exhaust radon |
| Ventilation systems | $1,323–$3,053 | Two fans remove radon and vent it outside |
| Water mitigation | $1,221–$5,088 | Uses carbon and aeration to remove radon from water |
Cost by Home Size
The larger your house, the more you can expect to pay for radon mitigation. That’s because installing a radon mitigation system in a bigger home often requires more materials and labor, which can increase your costs.
Cost by Home Age
Your home’s age also affects your radon mitigation costs in Boston. Older houses are more likely to have cracks in the foundation and other openings where radon can seep in, which can increase your pro’s workload (and your bill). Accessibility can also be an issue in some older homes. If your pro needs additional equipment to reach certain areas, they may charge more for labor.
Radon Mitigation Pro Costs
Your radon mitigation pro should include the cost of labor in their quote. Before hiring a radon mitigation company, make sure they’re insured and licensed to do business in Boston.
In addition, the Massachusetts Executive Office of Health and Human Services (EOHHS) recommends hiring a radon mitigation contractor who’s certified by the National Radon Safety Board (NRSB) or the American Association of Radon Scientists and Technologists - National Radon Proficiency Program (AARST-NRPP).
Permits
Since radon mitigation systems run on electricity, you’ll need an electrical permit to install one. In Boston, electrical permit costs depend on the specifics of the job. Your radon detection and reduction specialist in Boston can walk you through the permit requirements for your project and apply for the permits on your behalf.
Additional Pros to Consider Hiring
In some cases, you might have to hire multiple pros for this project. Here are a few examples of additional work you may need while installing a radon mitigation system:
Electrical work: An electrician can install wiring, replace a radon fan, or perform other electrical work required for this project. In Boston, it costs $189 to $631 to hire one of these pros.
Foundation repair: A foundation repair pro can fix foundation cracks and leaks to prevent radon from entering your house. On average, this type of work costs between $1,360 and $5,669.
Encapsulation: Sealing your crawl space—also known as encapsulation—is another way to reduce radon levels in your home. You can expect to pay several thousand dollars for this project.
Does a Radon Mitigation System Increase Home Value?
According to the American Lung Association, 21.8% of homes in Massachusetts have radon levels at or above the “action level” set by the Environmental Protection Agency (EPA). With a radon mitigation system installed by a licensed pro, you can protect your family’s health and safety—while also adding a valuable feature that buyers will appreciate if you sell your home.
