How Much Does Radon Mitigation System Installation Cost?

You’ve tested your home and found hazardously high radon levels. Now it’s time to install a mitigation system to reduce health risks. But radon mitigation can be a major unexpected home expense if costs are unclear. Understanding what impacts radon mitigation prices and estimating your total system installation costs lets homeowners budget appropriately.

The Health Dangers of Radon Gas

Radon is an invisible, radioactive gas that arises naturally from underground uranium decay. It seeps into homes through foundation cracks and openings. As radon accumulates in indoor air, it decays further into radioactive particles that lodge in lungs when inhaled, damaging cells and eventually causing lung cancer.

Radon is the second leading cause of lung cancer after smoking, according to the EPA. About 21,000 lung cancer deaths occur annually in the U.S. due to radon. The only way to effectively lower radon health risks is to install a mitigation system that vents gas from under the foundation.

Typical Radon Mitigation System Installation Costs

The average cost to install a radon mitigation system in an existing home ranges from $1,200 to $2,500. However, radon mitigation system costs can vary widely above and below that range depending on these key factors:

  • Home Size – Larger square footage requires more piping, equipment, labor.
  • Foundation Type – Concrete slab is the most affordable; crawlspaces or dirt floors increase costs.
  • Foundation Layout – Simple square or rectangle foundations are cheaper than “L” or uneven shapes requiring extra piping.
  • Radon Concentration – Levels above 10 pCi/L take more powerful, extensive mitigation equipment.
  • Radon System Type – Active systems have higher equipment costs than passive.
  • Radon Fan Needed – More powerful or multiple fans add expenses.
  • Vent Pipe Length – Longer vent pipe routes increase material and labor costs.
  • Additional Sealing Work Needed – More caulking and sealing raises price.
  • Construction Access Issues – Challenges like finished ceilings/walls or clutter add time/work.
  • Permit Fees – Some areas have pricier radon mitigation permit and inspection costs.
  • Contractor Experience – Newer contractors may charge less than seasoned experts.

Get an Itemized Radon Mitigation Quote

The best way to estimate your total radon mitigation system costs is to get a detailed, itemized quote from a certified professional contractor. Here are typical itemized costs:

  • Radon Fan Equipment – $350 to $1000
  • PVC Piping – $250 to $700
  • Fittings, Adapters, Caulking – $150 to $300
  • Electrical Wiring, Junction Box – $50 to $150
  • Vent Pipe and Roof Flashing – $100 to $300
  • Labor, Installation Work – $300 to $800
  • Permit Fees – $0 to $300
  • Post-Mitigation Testing – $150 to $250

When budgeting, plan a 10% to 15% cushion for contingencies like unknown foundation issues, additional sealing needed, pipe extensions, or hidden conditions. Using experienced contractors also ensures proper installation but may cost slightly more.

Financing Options to Pay for Radon Mitigation

Radon mitigation improves home safety and value. Still, the upfront system costs present a financial obstacle for many homeowners. If radon mitigation is not affordable for you right now, explore these financing options:

  • FHA 203(k) Loan – Covers radon mitigation through rehab mortgages.
  • Home Equity Loan/Line – Use home’s equity for financing.
  • Bank/Credit Union Loans – Some offer radon mitigation-specific financing programs.
  • Payment Plans – Ask contractors if they offer installment payment plans.
  • State/Local Grants – See if you qualify for area radon reduction financial aid.
  • Contractor Discounts – Negotiate a discounted rate in exchange for referrals or multiple systems.
  • Energy Utility Rebates – Program incentives help offset equipment costs.

Understanding typical radon mitigation system costs and financing aids homeowners in making this critical investment for protecting their family’s health and home value from the invisible radon threat.
