The majority of the radon removal systems can be installed in just a few hours, depending on the complexity of the home. Radon Investigators are experienced with installation process and knows how to efficiently and effectively get the job done.
The sub-slab depressurization method is the most common radon removal process. It prevents radon from re-entering the home by drawing the dangerous gas from underneath the foundation of the home and venting it out with a fan.
The simple answer to this question is NO. Radon is a gas and therefore can move through the concrete slab. However, sealing cracks may help to improve radon mitigation system.
The u-tube manometer is not an indication of the radon levels in your home, it is an indicator of the pressure created by the mitigation system. Radon testing is the only way to check the effectiveness of the radon mitigation system.
On average radon mitigation systems can be installed for under $1,500. Every home is built a little differently, and therefore, there is no universal price for every home.
