Radon is a finicky element. As construction techniques have evolved throughout the years, allowing for better drainage, radon gas has utilized these home improvements to its advantage. When buying new homes, particularly those built within the last decade, we want people to know what can be done about the potential of radon gases.
New vs Old Construction
Oftentimes, older homes are less susceptible to radon gas due to their lack of adequate drainage systems – such as drain tile or sump pumps. Without these open spaces beneath the home, much of the radon gas remains trapped in the clay and soil below.
However, new construction almost always has drainage systems that require plenty of digging and soil movement. Although these open-style drainage systems are incredibly effective in keeping basements dry, there is a negative side: radon seepage. With the earth disturbed, the radon is released, and it seeps into the large open spaces created for drainage.
When buying a new home, it’s vital that the house is tested for radon levels. At Certified Home Inspections, we lead the Northwest Indiana area in licensed home inspection, including radon testing and proper mitigation. If we discover radon in your future home, it’s important to delay occupancy until mitigation.
There is some good news, though.
If radon is discovered prior to a home purchase, the cost of removing the radon does not fall on you as the buyer. Installation of a radon mitigation system often falls right around the $1,000 mark. However, its the builder or seller that will need to cover the cost, not the buyer.
Additionally, the mitigation process itself is normally extremely effective in new homes. Due to the open drainage spaces built beneath the home, we’re able to enter our suction point and fan right at these previously built pathways. At Certified Home Inspections, we guarantee the removal of radon before it ever enters the home, every time.
