Radon Information

What is radon?

Radon is a radioactive gas. It is colorless, odorless, tasteless, and chemically inert. Unless you test for it, there is no way of telling how much is present.  Radon is formed by the natural radioactive decay of uranium in rock, soil, and water. Naturally existing, low levels of uranium occur widely in Earth's crust. It can be found in all 50 states. Once produced, radon moves through the ground to the air above. Some remains below the surface and dissolves in water that collects and flows under the ground's surface.


How does radon get into a home or building?

Most indoor radon comes into the building from the soil or rock beneath it. Radon and other gases rise through the soil and get trapped under the building. The trapped gases build up pressure. Air pressure inside homes is usually lower than the pressure in the soil. Once inside, the radon can become trapped and concentrated.


Openings which commonly allow easy flow of the gases in include the following:

  • Cracks in floors and walls
  • Gaps in suspended floors
  • Openings around sump pumps and drains
  • Cavities in walls
  • Joints in construction materials
  • Gaps around utility penetrations (pipes and wires)
  • Crawl spaces that open directly into the building

Mold Inspection

Even a few days of continuous exposure to mold can be harmful. The closer you are, the worse it gets. Children and infants are more prone to health problems, as are those with existing respiratory problems or allergies.  If you think you have mold we can inspect your property.

Sewer Scoping

Sewer scope inspections will determine the condition of the property's sewer line and to determine if the system is functioning as designed. This inspection provides another way to protect you from costly repairs later.

radon Testing

One in two homes has a radon level the EPA considers to be elevated - 4 pCi/L or greater in Colorado.  This service is included in our home inspection service, but we can provide testing outside of our home inspections.
