"I used this company to perform a home inspection before I bought my house. Due to its negligence and breach of contract, 9 months after I moved in, I had to replace the roof on the house. The company will do nothing to rectify the situation. They are cheats and liars that hide behind their contracts. Their inspectors take every shortcut, and they will not protect you during the home buying process. Just don’t use them."

"I have been a customer of Hedayat for well over 9 years, from the time his ad appeared in Angies List. He is an expert on all things carpets which means as an appraiser, in addition to the cleaning and repair services provided, the quality of the work is the best it gets. My carpets thanks to the care given, all continue to look as they did when I brought them back to the US from the Middle East 14 years ago. I highly recommend Art Connection to those members who are seeking expert evaluation of and care for their prized Oriental carpets."

"We needed a structural engineer to inspect the foundation of a home that we are purchasing and were recommended to contact Kemp. We are so glad that we did. Greg provided first class service. He was thorough and took the time to explain each step that he was taking, the purpose behind it, the potential results and what each could mean, and finally the actual results. He also took the time to educate us on some of the basic indicators of good and deficient or damaged home foundations. He was very personable and is great at making complex information simple enough for novices to understand. He also provided the inspection report almost immediately. We highly recommend Greg and his company’s services."

"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!"

"Setting up the service was an efficient process with the representative listening to what we needed done and providing a (reasonable) price over the phone. On the day of our service, the two-man crew was punctual, friendly and efficient. We initially walked through the house identifying all the registers and discussing the process. They then went to work and continued diligently and efficiently for over four hours. We were impressed with their attention to detail and care for our house (covering their shoes with "botties" when coming in from the wet outside; laying down when they started, a drop cloth by our front door where they stationed their heavy-duty HEPA vacuum; and then going around after they finished to vacuum bits of dust and paint that had fallen on our floors near registers that had been detached). Excellent experience."

FAQs for radon gas testing projects in Capitol Heights, 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.
