"The service was good. He showed up on time and did the test. The only problem I had was that he is not a full service, he only checks for asbestos and does not remove.The test took longer than I was told, but I don't think he had a choice. Overall he was ok, just not a perfect match for my needs."

"Chris was WONDERFUL! I just purchased a home and wanted to have a mold inspection done for peace of mind. Chris took time to explain the process and put my fears at ease with his vast knowledge. He reviewed the test results with me prior to closing which gave me the peace of mind I needed to confirm I was making a good purchase and great investment. I highly recommend Mid Atlantic Commercial Residential Real Estate Solutions. VERY PROFESSIONAL AND COURTEOUS!!"

"I was very pleased with the service and work done by SWAT environmental. Lance was very helpful in explaining the process when he booked my appointment and the two techs who installed the radon remediation system were professional and courteous. The system itself isn't inconspicuous but I feel safer knowing that our radon levels are significantly lower now."
