Radon Mitigation Cost Factors
The average cost for radon mitigation in Indianapolis, Indiana, depends on several factors, including the removal method and home size.
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 Indianapolis, IN | 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 | $2,700–$14,700 | Uses carbon and aeration to remove radon from water |
Cost by Home Size
The average home size in Indianapolis is 1,900 square feet, according to the Federal Reserve Bank of St. Louis (FRED) Housing Inventory. For the average radon mitigation cost of $800, you’ll spend a little over $0.40 per square foot. Here’s a breakdown of costs by home sizes:
| Home Size (Square Feet) | Average Cost |
|---|---|
| 1,000 | $400 |
| 1,500 | $600 |
| 2,000 | $800 |
| 2,500 | $1,000 |
Radon Mitigation Pro Costs
The cost to hire a radon detection and reduction specialist in Indianapolis varies by contractor, removal method, and scope. Most radon remediation projects take between four and six hours to complete, so for an average $800 project, pros charge anywhere from $150 to $200 per hour.
Licensing
Make sure you know who installs radon mitigation systems when searching for a licensed contractor. The state of Indiana requires radon remediation and testing specialists to be licensed through the Indiana Department of Health because this type of work can be dangerous if not handled safely and correctly.
Angi Tip
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.
Permits
Indianapolis requires professionals to possess active mitigator licenses and mitigation certifications from an Environmental Protection Agency (EPA)-approved program. However, the city does not require a permit for radon remediation.
Taxes
Indianapolis has a combined sales tax of 7.0%. For an $800 radon remediation project, add on around $55 in taxes to prepare for the total project cost.
Additional Pros to Consider Hiring
You may also need to hire additional pros when planning for a radon mitigation project, including electricians, basement finishing specialists, and foundation repair pros.
Electrician: $50–$100 per hour, may be required for rewiring, radon fan installations, or radon fan replacement services
Basement finishing: $7–$23 per square foot, may be necessary for sealing an unfinished basement or installing a new ventilation system
Crawl space encapsulation: $2–$10 per square foot, prevents radon from soil and water from entering your home through the crawl space
Foundation repair: $1.50–$12 per square foot, which keeps radon from entering your home through cracks
Indoor air testing: $300–$585, detects radon and other air quality issues
Does a Radon Mitigation System Increase Home Value?
If you live in a region like Indianapolis, where radon is a common problem, then investing in a mitigation system to prevent radon can increase your home’s value. This is especially true for health-conscious buyers who want to ensure their safety. Radon mitigation systems last for 20 years on average, so outdated systems may need to be replaced to make the most out of having radon mitigation for your home.

I recently purchased a home which the inspection found elevated levels of Radon. Before reaching out to Radon Technology, I called three other companies. Each of these companies simply gave me a price and that was it. Radon Technology was the ONLY one who had to see the basement before coming...
