"The structural/electrical/plumbing inspector was fantastic. He spent over 4 hours going through every inch of the home, provided immediate in-person feedback showing significant issues, and followed up <48 hours later (on a holiday weekend) with a 133-page report with pictures, thermal scans, etc. On a lesser note, the radon inspector showed for a few minutes during the structural inspection and set-up measurements in the basement. The report was issued quickly but I found out later that the radon inspector had not taken into consideration the attached (inaccessible) crawlspace that made up 25% of the lower structure. I found out from a radon remediation contractor that the state code required the radon inspector to measure levels on the 1st floor above the crawlspace in cases where the substructure could not be accessed. Overall, the huge amount of time the structural inspector put into the property was worth the A rating. Just watch the radon inspection if you have a strange basement set-up like the house I am purchasing."

Hello my name is Jason William Hornung. Buying a home is a big investment. I want to help you make a well informed decision. I have been in the residential construction field for 17 years, and have an intimate knowledge of the homes in our area having done so much work in them myself. I stay continuously trained studying current information to give the best reports out there. I've seen many things that other inspectors have missed both as a home inspector and a contractor. My inspections meet or exceed the ASHI standards of practice. WWW.Homeinspector.org/standards WWW.JWHInspections.com

"I waited a month before getting a test kit I called and was told there was something wrong with the Angies list orders but that I would be receiving a kit soon. It wouldve ben nice if they called me to tell me that though. The test results were quick and on par with other radon test I had done locally."

"We had a home inspection from David at RHS in 2015. He had been referred to us by our realtor. The report he gave us was so valuable. It resulted in the home seller fixing a number of important house issues before we completed the purchase. We ended up referring to the report for years afterward when we planned needed maintenance. In 2023, eight years later, we reached out again and asked if David could come do an inspection for the purpose of helping us prioritize needed maintenance. The one hour we spent with him saved us $15,000 in planned spending that we apparently didn't need to do just yet. We had several contractors told us we needed some specific things done, but it appears that was not the case. It's so helpful to have an independent and objective person with broad expertise that can help you know work needs to be done on your home when. At the end of meeting with him, we had a list of items we absolutely had to do (get new smoke detectors) and others that could wait a few years (getting a new roof). We were so happy with RHS and highly recommend this company."

"Robert was extremely informative and helpful during the inspection. He was willing to walk me through the process, explain what was happening, and educate me about mold and possible mold remediation options. Air samples are taken during this process that then have to be sent to a lab for analysis. This process took about 3 days and then I received an email with the lab report and a phone call from Robert to review the results. Luckily for us, mold levels were low enough that we are not going to seek professional remediation services. I would recommend RC Air & Mold if you are looking for an independent mold test. RC Air & Mold does not do remediation, so I felt that Robert's recommendations were not influenced in any way."

FAQs for radon gas testing projects in Walkersville, MD

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
