"The Radon Mitigation Specialists showed up as planned, on time and were extremely knowledgeable about the installation of the radon mitigation system. We decided on the perfect place to put it. When I changed the installation date, they were very accommodating and professional. Once the job was complete, it was better than I had expected. The price was more than reasonable and the cleanup was wonderful. I have loved the unit ever since. I highly recommend E&A if you want the job done right at the right price. Thanks guys!!"
