Radon Gas Mitigation Before & After Photos

A homeowner in Gloucester, Massachusetts became concerned about the radon levels in their home following an understanding of basement systems. The radon test results indicated levels between 6-9 pCi/L, exceeding the EPA's recommended action level of 4 pCi/L. In an effort to reduce the radon levels, they contacted Erickson Foundation Solutions.

Our Design Specialist, Tom Armano, recommended installing a radon mitigation system with a fan moisture guard and exterior aesthetic package. The installation team initiated the process by creating an extraction point through a small circular opening in the basement concrete floor for the radon mitigation system. A radon pipe was then affixed to this point and extended to the home's exterior, where the radon fan was mounted on the side. Additional piping from the fan was routed alongside the house, extending above the roof to prevent radon re-entry. After testing the fan for operational integrity, the team provided the homeowners with a charcoal test kit to reassess the radon levels after approximately one week.

With the proper precautions now taken, this homeowner has peace of mind that his home is safe from radon.

These homeowners in Portsmouth, New Hampshire recently bought their home in 2019 and had concerns with the radon levels. Shortly after moving into the home, they tested the home for radon. They wanted peace of mind knowing that the air in their home is mitigated from radon. So they decided to call EFS for a free inspection.  

The design specialist recommended a new radon system after the passive system wasn't accessible. Crew Lead Dillon Kingsbury and his team arrived at the home and installed the radon mitigation system into the basement.

A homeowner in Portsmouth, New Hampshire, had lived in their home for the past 30 years and recently became concerned with the levels of radon in their home. The home had two chambers, meaning they had a standard basement and a crawlspace off of the basement. The basement was mostly finished and the crawlspace was covered with crushed stone. The homeowner decided to call EFS for a free radon inspection, and our design specialist recommended installing a radon mitigation system with 2 extraction points. One of the extraction points was installed on the unfinished side of the basement and the other was installed in the crawlspace. The radon fan was installed on the exterior of the home to expel the radon-filled air into the air outside the home where it can dissipate.

A homeowner in Portsmouth, New Hampshire, lived in an 1880s home for the past 10 years. Earlier this year, the homeowner's were worried about the air quality in their house. They had a radon mitigation system installed but still felt like the air quality in their home could be better. They decided to call EFS for a free inspection and our design specialist Chris Greenwood recommended installing an ERV system and a SaniDry into the basement to improve the air quality in their home. 

The ERV will bring fresh air into the home and remove old stale air while the SaniDry will keep the humidity in the home at a comfortable level. 

A homeowner in East Wakefield, New Hampshire, was selling their home so they could move to a warm climate to avoid the harsh winters of the northeast. The homeowners had tested the radon levels with they purchased their home 22 years ago when they purchased the home and the levels were very low, but now the levels were higher than the recommended amount. The homeowner decided to contact EFS about installing a radon mitigation system in the home so it would be easier to sell. Our installation team installed a radon mitigation system into the home and reduced the radon levels to below 4.0 pCi/L.
