"I had a poor experience. I hired this company to do a mold assessment in my apartment. I dealt with the owner. First, he requested cash or check payment only. He made an appointment and did not show up or contact me. I had to call him. In one of the rooms, the pipes above and whatever else the cause of the leak was, had been leaking repeatedly for 40 years, and the plaster constantly replaced. I was worried about mold ABOVE the ceiling on the beams and studs and not just the visible mold on the ceiling plaster and I worried it could be black mold. He did not seem to listen to what I told him and he did not use a water meter to check for saturation or a borescope or any other tools except taking a surface sample and air sample (the borescope and water meter I did not know about until after I had paid him for this inadequate job). He did not mention anything I said in the report. He was also rude and unkind and never provided me with a receipt."

Radon Detection and Reduction questions, answered by experts

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

Yes, if high levels are detected, professionals can provide solutions for radon reduction.

You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional. 

A DIY kit can lessen the sting that comes with paying for a professional assessment, but these comprehensive tests are true lifesavers. Inspectors are more likely to catch all of the pollutants and hazards in your air. Plus, you’ll still need a professional to verify and act on your DIY test results. 

Some kits don’t include tests for certain air pollutants or only detect their presence, but not their levels (i.e., mold spores). If you’re willing to shell out money for a DIY kit, it’s usually better to stretch your budget slightly higher for a more detailed assessment.

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.
