"My only regret is not hiring Adam Contracting sooner. From the beginning of the project, I was updated on the schedule and cost. All of the employees were professional, and skilled, and left my house clean after each task. If I had issues or noticed something that needed to be changed the owner addressed the concern immediately. I am very happy with the finished project!"

"I carefully read and compared company reviews and have had several home inspections over the years, so I expected a quality inspection from HomeKey but even going into it with high expectations I was still surprised and impressed with the thoroughness and conscientiousness of the inspection. My inspector was Mike, and the home is an older one owned by an elderly person so there were many issues to evaluate. The inspection took much longer than the average amount of time and the report was much longer and required much more work to produce, but there wasn't the slightest hint of rushing any of it or skimping at all. I myself suggested the roof could be skipped because I was worried moss had made it slippery and figured it was surely pretty much gone anyway, but Mike bravely went up there, made sure it was safe, then took a good long while in the heat and returned with photos and an issue that requires immediate attention. Likewise, I was surprised at the willingness to enter a very cramped dirt floor crawl space and proceed around the entire foundation... out of sight into the nether reaches... but I have photographic proof! Those are just two examples out of many, but from under the floors to over the ceilings in attic spaces accessible only through ceiling hatches, Mike examined every detail, took photos, and carefully documented the entire process which resulted in a long, thorough and informative report that will make the purchase decision better informed and provide structure for repair decisions. The price of the service was pretty much the going rate, and thus reasonable. I don't see much spread in the pricing of home inspections across companies, so I would feel cautious of any company that deviated by much. The difference in value for your cost would then be the quality of the inspection. Honestly, the cost of HomeKey's inspection could have been higher and would still have been well worth it for the care, time spent, the information provided, and for the assurance having a trained eye on things can give you."

FAQs for radon gas testing projects in Alexandria, VA

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.
