New Homes Need Radon Mitigation Systems
Safe Shelter partners with builders to ensure radon resistant new construction techniques.
Whether you are a building contractor or owner looking to build, any new home construction plans should include radon-smart design, commonly known as Radon Resistant New Construction (RRNC).
Pennsylvania has one of the most serious radon problems in the United States. Approximately 40 percent of Pennsylvania homes have radon levels above Environmental Protection Agency’s action guideline of 4 picocuries per liter.

PROACTIVE RADON MITIGATION IS THE MOST COST-EFFECTIVE SOLUTION
While SSE can retrofit any home, school or business with a custom-designed radon mitigation system, there are many benefits to building with radon prevention in mind.
First and foremost among those reasons is cost savings. Planning for radon mitigation in advance removes some of the trickier obstacles to retrofitting. The radon mitigation vent pipe is built directly into the framework of the house, removing the labor cost of adding one after the fact. This also allows us to hide the pipe within the walls, rather than have it run up an outside wall of a house.
If you are a home builder, you are aware that most real estate transactions include a radon test as a contingency in an offer to purchase. Installing a radon mitigation system while the house is being built not only saves the homeowner significant cost over retrofitting the system after construction is complete, but it also adds to the appeal of the homes you build, enhances your reputation as a home builder, and ensure there won’t be any snags in a real estate transaction going through.
HOMES PURPOSE-BUILT FOR RADON REDUCTION ARE HEALTHIER
Homeowners will also find environmental advantages of living in a home equipped with radon mitigation equipment. Radon ventilation systems remove as much as a gallon of water from below the home every two hours, preventing growth of molds and bacteria which trigger allergies and illness. Because of the reduced moisture in the air, these homes also tend to run their energy-consuming dehumidifiers less frequently.
Benefits of Radon Mitigation:
Fan-based mitigation systems can filter out the moist air from the soil beneath your home. An active system can pull as much as a half-gallon of water per hour from beneath a slab foundation or basement.
Lower humidity has added health benefits in the form of fresher interior air and the elimination of musty smells. Decreased humidity means reduced or dampened antagonisms in the form of bacterial growth, mildew, and dust that can aggravate asthma, allergies, and other lung conditions.
Less humidity can mean decreased dehumidifier usage, if you need a dehumidifier at all. In addition, HVAC systems also run less frequently. Decreased demand for energy-hungry air conditioning systems translates to a lower electric bill and an added benefit for the environment—fewer emissions.
Increased home value.
Radon mitigation system help increase home salability. It also eliminates protracted negotiations over who pays for the installation when a house is on the market.
HOW DOES A RADON SYSTEM REDUCE MOISTURE?
Soil vapor gets drawn into your home as your home replaces the air that escapes from open windows and ventilation; think of your home like a giant vacuum that’s constantly pulling in air from below the foundation. Radon systems draw radon gas out of a home from underneath the home’s foundation (below the concrete slab) through a process called sub-slab depressurization, which creates a vacuum seal. This same process is continuously drawing out the moist/damp air from underneath your home’s foundation, which is how it is able to (eventually) dry out the basement. Of course, every home is different and the effects of a radon system reducing moisture as a byproduct of reducing radon gas can vary from home to home.
Many new homes being built today are advertised as Radon Resistant New Construction (RRNC for short). You would think with a name like this the homes actually resist radon, but all RRNC means is that radon mitigation system pipes have been pre-installed in the home. Typically, they run up through walls inside the home for a more discreet installation than what is done on existing homes.
Trouble is, there’s no radon mitigation fan in place. Without a fan, you have what’s known as a passive radon mitigation system—which accomplishes very little. You really need the exhaust fan to actually remove radon and have a truly radon resistant home. For the small cost of having a fan installed, you are better off bypassing a radon test altogether and just getting a fan installed.
An active Radon system in the home offers major advantages, such as:
- Improving the indoor air quality
- Reducing the moisture content in the air before it enters the home
- Aids in inhibiting moisture that otherwise accumulates in slab or basement floors
- Improves control of the differential pressure between the soil and the interior of the building
- Makes indoor humidifiers redundant
- Runs quietly on “automatic” requiring no maintenance
- Costs mere pennies to operate while the health benefit is priceless
