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

    Jack was a great source and wealth of knowledge about a house that has been in my family for generations. Very personable and helpful to my house buying journey. Would always go here for my inspections.

    Had Jack as our inspector. Great business and work ethic overall. He was patient with my husband and I as first time home buyers/owners (we asked SOOO much, sorry Jack!), and made sure we were well informed of every issue. The inspection … More itself was thorough and went above and beyond our expectations. We recommend them and will use their services again in the future if need be!

    We had our new home inspected by Castle Home Inspections. Steve was our inspector and he did a very thorough and detail job of inspecting the home with a complete written report. I would recommend Castle Home to anyone looking for a home … More inspection.

    We had a home inpection on a home we were hoping to purchase. Steve was incredible. He was very thorough and provided us with details along the way. He took his time and ensured all of our questions were answered. He made us feel confident … More that any issues had been uncovered during our inspection.
