You Can't Prevent It! You Can Manage It!
There really is no such things as radon prevention.
Even with a radon reduction system installed properly you may, at some point in the future, discover rising radon gas levels in your home. This is usually due to ecological and structural changes occurring deep beneath your homes structure. These shifts, often referred to as “settling” may cause new cracks and gaps in your foundation and must be addressed to prevent radon gas build-up.
Both the EPA and IEMA recommend that you test your home every two years, after installing a radon mitigation system, to keep radon levels in check.
Should you find radon levels exceed the EPA guideline of 4 pico curies per liter, contact your original radon contractor. Depending on your contractor, resolving increased radon levels post mitigation may be covered by your service agreement for a period of time. Professional Radon Systems, Inc. for example, will rectify radon levels above safety standards, at no cost to the home owner for a period of 5 years (provided you have not had any home modifications or remodeling done). If you don’t know who installed the system give us a call. We provide maintenance and upgrade services as well.
Maintaining Your Radon Reduction System
First, Remember, the fan should NEVER be turned off; it must run continuously for the system to work correctly!
Similar to a furnace or chimney, radon reduction systems need some occasional maintenance. You should look at your monitoring devices on a regular basis to make sure the system is working correctly. Fans typically last five years or more (manufacturer warranties tend not to exceed five years) and may then need to be repaired or replaced.
Structural Changes to Your Home
If you decide to make major structural changes to your home after you have had a radon reduction system installed (such as converting an unfinished basement area into living space), ask your radon contractor whether these changes could void any warranties. If you are planning to add a new foundation for an addition to your house, ask your radon contractor about what measures should be taken to ensure reduced radon levels throughout the home. After you remodel, retest in the lowest lived-in area to make sure the construction did not reduce the effectiveness of the radon reduction system.
Buying or Selling a Home
If you are buying or selling a home and need to make decisions about radon, consult EPA’s Home Buyer’s and Seller’s Guide to Radon. If you are selling a home that has a radon reduction system, inform potential buyers and supply them with information about your system’s operation and maintenance. Most mitigation companies honor warranty transfers to new owners. Check with your mitigation contractor to be sure!
