Radon mitigation in Marion and Hiawatha

Marion borders Cedar Rapids to the northeast and had 41,535 residents at the 2020 census, up about 58 percent since 2000, making it one of Iowa's fastest-growing cities. It was Linn County's first seat of government before the seat moved to Cedar Rapids in 1919. Hiawatha and Robins sit just to the north. Much of the area's housing is newer, with plenty of finished basements.

Newer homes still need testing

A newer house doesn't mean low radon. Tight, energy-efficient homes can trap radon, and some newer homes have passive radon pipes that were never activated with a fan. If your home has a capped pipe stub in the basement, a radon company can tell you whether adding a fan makes sense after testing.

What radon work do Marion-area homes need?

• Testing in newer homes and finished basements
• Activating passive radon systems with a fan
• Interior pipe routing to keep finished spaces tidy
• Testing and systems for home sales

Finishing your basement?

Test and, if needed, mitigate before you finish a basement. It's easier to route a pipe and seal the slab before walls and flooring go in.
