Residential: Inspections are conducted according to InterNACHI’s Standards of Practice.

Commercial: Inspections are based upon InterNACHI’s Commercial Standards of Practice with the scope of work being defined by the customer and RJE Property Inspections and priced according to the agreed upon scope of work.

Radon is an invisible, naturally occurring, colorless, odorless, radioactive gas that is a product of the decay of uranium. The U.S. Environmental Protection Agency (EPA 1992) estimated that between 7,000 and 30,000 lung cancer deaths in the United States each year are caused by breathing radon gas. In fact, radon is believed to be second only to smoking as the major cause of lung cancer in the United States. Although the EPA and the Surgeon General warn that smokers have a higher risk of developing lung cancer from radon exposure than non-smokers, the radon levels in all homes can be reduced.

Very low concentrations of uranium occur in many rocks and soils. Some rock types, such as granite, contain more uranium than others, and thus produce more radon. However, most soils in Montana generate at least some radon. The half-life of radon is 3.8 days. Radon concentrations are measured in units of radioactivity called picoCuries. The national average background level of radon in outdoor air is between 0.2 and 0.7 picoCuries per liter (pCi/L). For indoor air, the national average is 1.3 pCi/L, but in Montana the average is 5.9 pCi/L.Radon gas can move from the surrounding soils and accumulate in enclosed areas such as homes and underground mines, when the atmospheric pressure inside the structure is lower than the surrounding pressure. Indoor air that is warmer than outdoor air rises in homes and pulls cooler air in from the outside. Blowing wind and heavy rainfall can also increase the movement of radon into a house.


Thermal Imaging:
Infrared cameras translate the heat signature of objects into colors on a gradient scale, with higher temperatures appearing as lighter colors, and lower temperatures and wet areas appearing as darker colors.  Thermal images show surface-heat variations, which is why an Infrared camera is such a diverse tool for home inspections. Abnormally hot electrical components and connections can be viewed during an electrical inspection. Areas of moisture that may lead to leak and structural damage can be located based on apparent temperature differences. Heat loss and air leakage in a home, even areas of insufficient insulation, can be pinpointed quickly using an infrared camera.
