Garden ln cape Elizabeth

This job was a unique one. This house was right on the oceanfront and when high tide occurs the basement floods. This basement had current radon mitigation system with 2 extraction points however with the installation of several sump pumps and water guard drainage system it was allowing the radon gasses up through these areas. The water guard could not be sealed due to the amount of water that come in. So we chose installing an erv as the next best choice. This erv we added a damper on the stale air so we can create positive pressure which will reduce the radon levels in this home.
