"Excellent Water/Well Testing Service from NextDay Inspect – Highly Recommend! I recently had a water/well test done by NextDay Inspect, and I couldn’t be more satisfied with the entire process. From scheduling the appointment to receiving the results, everything was seamless and professional. Sonya, the inspector who came out, was amazing. She was punctual, thorough, and took the time to explain the entire testing process. She made sure I understood what was being tested and why, which gave me confidence in the results. The whole experience was smooth and stress-free, and I really appreciated how well everything was organized. The results were delivered quickly, and NextDay followed up to make sure I had all the information I needed. I can confidently say that NextDay Inspect provides top-tier service, and I highly recommend them for anyone needing water/well testing."

"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."

"Inspector (the individual) personally recommended by my realtor.  He arrived at the home a few minutes before the scheduled time and had already begun the outside survey when I arrived.  The inspection was very thorough and found several cosmetic items that both the agent and I had overlooked plus several electrical issues that would otherwise never would have been spotted (including inside the breaker panel which he opened).  Based on the professionalism exhibited by the inspector, I ordered a radon test (over a 3-4 day period) which did identify exposure at very slightly above the recommended limit (and which was remediated by the builder). <br /> <br /> Because of the electrical issues that turned up during the inspection, I scheduled a re-inspection to be performed after the builder had made corrections (I didn't feel qualified to judge those corrections).  Again, the inspector was on-site slightly before the scheduled time and completed the re-inspection in accordance with my expectations. <br /> <br /> At the time the inspection was scheduled, USInspect had provided a very detailed explanation of what the inspector would, and would not do, during his inspection.  Unlike some other reviewers, I was, therefore, able to anticipate just what to expect."

"The inspectors arrived on time and did a very thorough check of the home. I was impressed by all they uncovered. I would have never thought to check the items that the inspectors did down to the speed at which sinks drained and the temperature in the refrigerator. The inspection report was arranged by category and even included a summary at the end that identified the major problems. I don't know how any other home inspection company can stay in business, when they have to compete with A House on a Rock."

"Ray performed a very thorough home inspection.  He was punctual, professional, and very helpful.  He spent lots of time with us after he completed his inspection reviewing his findings and helping us to understand what was an important fix, what could wait, and what was a minor issue.  He took well over a hundred pictures of every part of the house and went through them with us in detail. <br /> Also, Jenn (who manages appointment scheduling) was very helpful and thorough on the phone.  She discussed radon testing with me, and, after our discussion, for various reasons she recommended against performing any testing at the time of inspection.  I really appreciated her honesty. <br /> I would definitely hire Capitol Home Inspection again. <br />"

"During home inspection on the house we are selling, radon tested above acceptable level. Commonwealth provided an estimate of work to be done and cost. They retested, determined it needed mitigation, drilled a neat hole in basement floor, installed pipe that led to outside, fan, arranged for electrician, retested, and provided report - levels very good."

FAQs for radon gas testing projects in Ashland, 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.
