I would recommend Atlantic Real Estate Services for radon mitigation services. Tommy was very knowledgeable and spent time explaining his plan and process to me. I live in a townhouse and he took the extra time and effort to ensure the system was done well and in a fashion that is beneficial to the home owner. He ran the exhaust piping through our basement ceiling in order to keep it out of sight and because our maintenance room and sump pump are in the front of the house. No other company who quoted us were willing to run the exhaust through our ceiling. So far the radon levels have maintained below 1.0. I was very pleased with his work.
Besides the radon pump and plumbing, Tommy did a great job installing a plastic membrane over our dirt crawlspace. The system lowered typical radon counts from 11 to 1, below 4 is considered healthy. The plastic membrane knocked down the humidity in the basement which helps an area prone to mold. He was on time, respectful and priced competitively.
