Practical resources for homeowners

Radon

Radon is a common concern in our Colorado mountain communities. Colorado is located in Zone 1 which represents high radon potential. Radon is a naturally occurring radioactive gas that comes from the breakdown of uranium in the soil beneath your home. Radon is odorless and colorless gas that will go undetected without proper testing.

Health Risk of Radon

Stack Effect

The “stack effect” is when warm air moves upward in a building. This happens in summer and winter, but is most pronounced in the winter because indoor-outdoor temperature differences are the greatest. Warm air rises because it’s lighter than cold air. So when indoor air is warmer than the outdoor air, it escapes out of the upper levels of the building, through ventilation openings, or penetrations and cracks in the building envelope. The rising warm air reduces the pressure in the base of the building, forcing cold air to infiltrate through doors, windows, or other openings. The stack effect basically causes air infiltration on the lower portion of a building and exfiltration on the upper part.

Ice Dams

Ice dams form on underperforming roof assemblies.  Ice dams are dangerous to people and cause expensive damage to roofs and interiors from water leaks.
