Radon Inspections

Radon is a naturally occurring radioactive gas.  When elevated, it becomes the second leading cause of lung cancer.  It is a tasteless and odorless gas derived from the radioactive decay of radium.

What To Expect

  • Testing during a real estate transaction requires a short-term radon test.
  • A continuous radon monitor (CRM) is placed in the lowest possible living area of the home.
  • The testing period is a minimum of 48 hours.
  • Results will indicate an EPA level that is either safe or elevated
  • Homes where the lowest living area exceeds 2,000 square feet, a second monitor will be used.
  • Mitigation and/or retesting will be recommended for elevated levels.
  • PVC piping and an inline fan are installed to keep radon levels at a safe level, below 4.0 pCi/L.

What Will It Cost?

Radon Inspection fees vary based on the size of the lowest level. Prices may be subject to change based on unforeseen variables.

Prices range from $160 – $260
