Mitigating An Old Home

An old home can pose many issues to radon mitigation. The main one being that they often have many additions, so a regular system where we apply suction underneath a foundation isn't as feasible. Or they have large dirt crawlspaces that are hard to encapsulate and mitigate.

This is where an energy recovery ventilator (ERV) can be useful. With this system, we can feed the home with fresh air and exhaust the stale indoor air. If the radon levels are less than 8 pCi/L, this approach works very well, because it lowers radon levels on average by 70%.

ERV systems operate by exchanging stale indoor air with fresh outdoor air, while also transferring heat and moisture between the two streams. We can also balance the two air streams where we put more fresh air into the house, pressurizing the area, which helps to dampen the radon from entering. ERVs also prove effective by diluting the concentration of radon in indoor air with the introduction of fresh, uncontaminated air from outside. As the ERV facilitates the exchange of air, it helps reduce the overall radon levels, mitigating the potential health hazards associated with prolonged exposure.
