"Dwight was professional and friendly from the moment he arrived to do a home inspection for us. What stood out and was complimented by our realtor as well was the fact he brought in folding chairs for us to sit in because the house was empty. Even our realtor said she had never had an inspector do that and we were blown away by the thoughtfulness and customer service that showed. Dwight was extremely thorough and made sure to communicate prior to starting, during, and after the inspection. He went beyond explaining recommendations and elaborated in a way I could understand. He was patient while answering questions and overall an absolute pleasure to work with. Our report was emailed in just a couple hours following the inspection. I highly recommend A House on a Rock and thank Dwight for the wonderful experience he provided. "

This is a pile of bat poop in the attic. Bat poop is toxic, and this is going to be an expensive clean-up job.
Looks like the homeowner cut all the trusses in the attic to make room for storage. Unfortunately, those were all structurally important components that they cut.
Typical "flip" plumbing, There is no trap which allows sewer gasses into the home. Plus, even if there was a trap, there was no vent, so it may have siphoned the water out of the trap.

"Had a great experience with Chris Kuper at Basement Detective! My basement flooded from non-stop storms and I needed a sump pump installed along with complete renovation of my basement. They were very competitive in pricing and outstanding in results. Chris even helped coordinate with the contractor doing my basement renovation after the sump was installed to make sure none of the drainage was disturbed by the new work being done. I have since weathered at least 3 large storms and can hear the sump working as needed. Very happy with the results!"

FAQs for radon gas testing projects in Richmond, 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.
