I cannot say enough positive things about Mitchell and his team. Our radon levels came back a little high, and after getting a couple quotes, we decided to work with GA Radon Solutions. They had excellent reviews and Mitchell was so patient and helpful in helping us understand the problem and how to fix it. They take a very scientific approach, and their work caused our levels to go way below the EPA standard of 4.0. Mitchell was wonderful to work with, answered all our questions and did an outstanding job. They may be a little pricier than others, but the finished product is well worth the extra expense.
