"I am a realtor and have used other companies for radon testing before. The Maryland Home Inspection technician was very responsive and timely. I would use them for other clients."

"I scheduled the radon testing with Bill. He was very thorough and accommodating. Bill agreed to meet my real estate agent at the property to set up the testing equipment. As promised, the test results were provided in a report format and after 48 hrs. Great service."

"I called Adam Contracting LLC primarily to fix a leaky pipe underneath the sink in one of my bathrooms. I bought the $59.00 handyman services for 2 hrs thinking it would take that long to fix the leak. I was so wrong. Israel, one of Adam Contracting's technicians, took approximately 10 minutes to fix the leak. I was so happy. I had delayed getting the leak repaired because I thought I would incur some unheard of cost, but working with Adam Contracting, I was able to stay within the $59.00 price. Also, since Israel got finished so quickly with the leak, he was able to repair other things I wanted to have done in my house.
Israel, the technician, was professional, knowledgeable, and punctual.
I will definitely use Adam Contracting LLC in the future for household repairs.

"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!!"

"JT of Dragon Ridge performed a Home Inspection and Radon Testing of a SFH in Fairfax, VA. JT arrived before I did, and was already examining the exterior of the property. While we waiting for my realtor to arrive, he grabbed a ladder and did a complete inspection of the roof (not all inspectors do this). Once we got inside, he explained the processes and we began. I shadowed him throughout the whole processes, and it was a wonderful experience. He was very thorough and knowledgeable, and was always willing to provide complete and educational answers about both the good and the bad he found. We got the report later that evening, and it was well written, with plenty of pictures of any deficiencies. He also performed a Radon test, and reported the results a few days later. I spoke to him over the phone about the findings, and he was able to discuss in detail the methodology he used, and the meanings of the testing numbers. Overall, I would highly recommend JT and Dragon Ridge."

"These guys were AWESOME. They arrived within 90 minutes, assessed, estimated, and had equipment already with them to handle our flooding. They moved the furniture, explained how it all worked, came back half way through (it was a 3 day process), moved the fans, and then put it all back when they were done at the end of the 3rd day. If every company worked like this - had staff as professional, friendly, and reassuring as these guys - there'd be no need for a better business bureau! Love them. Don't hesitate to use them!"
If radon is present in your home, you can expect to pay around $1,000 for a radon mitigation system or between $780 and $1,250 in most cases. The exact price will depend on the severity of the radon leak, home size, and the protocol the radon specialist develops to remove radon from your home and keep it out. Your foundation type will also affect your radon mitigation system cost, as unfinished basements will cost about $4,600 to seal and ventilate, while crawl spaces without a foundation slab may need extra encapsulation, costing $1,500 to $15,000.
You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional.
Radon testing costs depend on whether you hire a professional radon inspector or DIY test. You can expect to pay $150 to $800 to hire a local radon inspector, and home-testing kits range in price from $15 to $250 from home improvement stores. However, it’s best to trust a professional inspector with this task to ensure accurate results. Plus, if you have radon in your home, your testing company can develop a mitigation protocol to keep you and your family safe from the dangerous gas, so it’s well worth the money to hire a professional.
Yes, radon testing is absolutely necessary if you suspect the presence of this hazardous gas, and the Environmental Protection Agency (EPA) recommends testing for all homes in the country. Radon is a pervasive natural gas that can leak through your home’s foundation and seep into the living areas. Unfortunately, the gas is highly carcinogenic and is the second leading cause of lung cancer. Radon testing is crucial for keeping you and your family safe from harm, so hire a radon mitigation specialist to test your home if you suspect its presence in your home.
In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.
