"Ted Riddick did an excellent job of performing a mold test in our basement, at the buyers request. I was very leary at first, because we recently cleaned the carpets and were concerned and/or confused that mold could be in our basement. We certainly would have known if we had mold in our basement or water coming causing a mold situation. Needless to say no mold was found, and my worries were alleviated. Mr. Riddick is a seasoned inspector, with a deep knowledge all areas of home inspections. He was professional, kind, did a great job."

"This is the 3rd time we have used Bee Secure Home Inspections, and each time it has been exemplary. Michael spends as much time as you need with you going through each of the areas for home inspection as well as gives you suggestions and tips how to upkeep your home. He is very knowledgeable about each and every aspect of the home and goes above and beyond to get the perfect report. His report is very thorough and easy to read. He has dealt with my and my partner's father on the jobsite answering every question they had, impressing them both. In the future, I will be reaching out, since out of all the inspections, Bee Secure, has been the best."

"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!!"
