Radon Mitigation Systems

A variety of methods can be used to reduce radon in homes. Sealing cracks and other openings in the foundation is a basic part of most approaches to radon reduction. EPA does not recommend the use of sealing alone to reduce radon because, by itself, sealing has not been shown to lower radon levels significantly or consistently. In most cases, systems with pipes and fans are used to reduce radon. Such systems are called "sub-slab" or "sump suction" systems, and do not require major changes to your home. These systems prevent radon gas from entering the home from below the concrete floor and the foundation. Similar systems can also be installed in homes with crawl spaces. The right system depends on the design of your home and other factors. As with any other household appliance, there are costs associated with the operation of the radon reduction system.

Ways to reduce radon are discussed in the EPA's "Consumer Guide to Radon Reduction". Call our office to receive a free copy.

Please see our notice concerning homes with sump pumps.

Radon Environmental has been installing Radon Mitigation Systems in central Indiana homes since 1988. We can confidently say we have never encountered a house we could not fix. We are state licensed for radon testing and mitigation.

INSTALLATION AND OPERATING COST TABLE
Technique	Typical Radon Reduction	Typical Range of Installation Costs	Typical annual operating cost	Comments
Subslab Suction (Subslab Depressurization)	80-99%	$600-$1,200	$75-$175	Works best if air can move easily in material under slab.
Blockwall Suction	50-99%	$800-$1,200	$150-$300	Only in houses with hollow blockwalls; requires sealing of major openings.
Sump Hole Suction	80-99%	$600-$1,200	$75-$175	Works best if air moves easily to sump under slab; or if draintiles form complete loop.
Submembrane Depressurization in a crawl space	80-99%	$1,000-$2,500	$70-$175	Less heat loss than natural ventilation in cold winter climates.
Powered crawl space ventilation	50-99%	$600-$800	$200-$400	Cost varies based on age and airtightness of home.
Sealing of Radon Entry Routes	0-50%	$100-$500	None	Normally used with other techniques; proper materials & installation required
* NOTE: The fan electricity and house heating/cooling loss cost range is based on certain assumptions regarding climate, your house size, and the cost of electricity and fuel. Your costs may vary. Numbers based upon 1991 EPA data.
