"Rodney is great. Very responsive, reasonably priced, and sends reports very quickly. He does all my lead paint inspections for all my rental properties. I've worked with several lead inspectors and won't use anyone else. Highly recommended."

"Buying a home is stressful process itâ s very hard to find people you can trust today. The best part of this experience was the home inspection. Jared and the inspectors were easy and helpful from the start. They did a fantastic job of helping and explaining things to me. I price shopped before hand and talked to a few other companies and decided to go with the inspectors and do not regret it. Top notch work from top notch people! Do not hesitate to do business I know I will call them again!"

"Things went well. We had a poor sales experience due to a previous salesperson that did not fully disclose the situation I would experience, however Floodbusters did make the situation right and warrantied the product to ensure that my experience moving forward was the best it could be given the complexity of my basement situation. They continue to work with me and believe me if you have any situation like I do in regards to Iron Ore and the devastation it delivers to your waterproofing system, this crew through my experience is the team now to hire."

FAQs for radon gas testing projects in Havre De Grace, 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.
