Radon measurement has been around for 20 years, but has recently come to be one of the most used services that Pinnacle Property Inspections Services performs for their clients.  When my client from the Barrington home inspection called, he wanted to know if I could tell if the home had radon by the year it was built.  I explained that It was impossible to tell if the home had high levels of Radon gas without performing a radon measurement.  Radon gas is a derivative from Radium which comes from Uranium.  All of these materials are natural occuring and are components of the earth that can not be eliminated but reduced in homes and buildings.  Radon gas has characteristics that make it impossible to detect without testing equipment.

  • Radon gas is colorless which means that you can’t see it in the air or as dust.
  • Radon gas has no smellCompletely odorless.
  • Radon gas has no taste.
  • Radon gas is known to cause lung cancer.

Radon gas can be found in new homes, old homes, condo buildings, office buildings, warehouses.  All properties have some amount of radon gas that is moving throughout the building.  Radon measurements are the only way to tell how much radon your home will have.  In Illinois we use a continuous radon measurement for 48 hours to deliver a non-bias result.  We often suggest radon mitigation systems to be installed in homes that have radon measurement higher than 4.0   (pCi/l).  We do thousands of tests and you can check your cities averages.  My client from the Barrington home inspection had a 2.6 pCi/l reading which is acceptable.

There are many myths about which homes have radon and many homes that could reduce their homes radon gas levels by following the list below.

  • Sump pump covers and pits should be sealed.  Radon gasses are notorious from entering the home from the drain tile piping under the home that delivers water to the pit.
  • Crawls spaces that are dirt or gravel should be seal tight with a plastic material to prevent the radon gases that may or may not be present from entering the home.
  • Basement cracks in the floor should be sealed to prevent the radon gases from emulating from these cracks.
  • Gaps around the perimeter of where the foundation meets the floor of the basement slab should be sealed to prevent radon gas entry to the home.

I explained these radon reducing methods to my client from the Barrington home inspection.  I was hired to do a retest after my client performed these repairs and his radon measurement was 0.9.  This is a great radon measurement that is below the national average.  As you can see, my clients from the Barrington home inspection received an education on radon and the causes and effects.
