Radon testing

Radon is a serious health hazard and the second-leading cause of cancer in the U.S. It is a colorless, odorless, radioactive gas forms naturally in the ground. When it gets into the air or water in your home, it can cause serious health concerns, including cancer.

We offer radon testing services by a certified inspector as an extra service at Top Notch Inspections. It’s the best way to get an accurate reading of your property’s indoor air quality. You can add on the service as part of a complete home inspection or as a stand-alone service at any time.

Radon is a highly toxic gas, and is the number one cause of lung cancer among non-smokers, according to estimates by the Environmental Protection Agency. It is responsible for more than 21,000 lung cancer deaths every year.

That’s why radon testing has become an important part of inspection checklists for home buyers, sellers and listing agents. Property managers also can benefit from radon testing of townhomes, condos and apartments.

We use special equipment designed specifically to detect the invisible, odorless gas. Our system samples indoor air quality through a passive diffusion chamber that we set up in your home. Its compact, cordless design stays out of your way and works silently to collect accurate information.

After your testing period, you receive a radon report with precise measurements of the radon level in your home. Your report may include notes about your readings to give you the information you need to make decisions about your property.

Radon testing by Top Notch Inspections gives you peace of mind that your home is a safe environment.

Why test for radon

Any home can have a radon problem. That includes new and old homes, well-sealed and drafty homes, and homes with or without basements. 

In Idaho, two out of every five homes have an elevated radon level of 4 pCi/L or more, according to the Idaho Department of Health & Welfare. High risk areas include Boise, Elmore and Valley Counties, based on statistics from the Environmental Protection Agency.

The most common way radon gets into your home is through soil around the house. Here are other paths radon takes to enter your home.

  • Cracks, pores and holes in the foundation
  • Floor-wall joints
  • Mortar joints
  • Sump pump
  • Soil in unfinished crawl spaces
  • Well water
  • Cavities inside walls
  • Loose-fitting pipe penetrations
  • Granite, brick, concrete or rock materials
