"DO NOT LET THEM IN YOUR HOME WITHOUT PROOF OF LIABILITY INSURANCE! BEWARE! This company and its inspector, C. Scott Burns, do not follow accepted home inspection standards and caused thousands of dollars in damage to my property during a home inspection. Despite providing pictures, documents, and fulfilling every request, the owner, Jeffery Donaldson, refused to pay for the damage. He only communicated through a generic customer support email and repeatedly refused to identify himself. A quick search of court records in Berkeley, Charleston, and Dorchester counties will show that he has been involved in numerous lawsuits. I have been forced to seek legal action as well. STAY AS FAR AWAY FROM THIS COMPANY AS POSSIBLE. If you are buying or selling a home in the Charleston, SC area, ask who the inspector is and ensure you get a copy of their insurance policy before allowing them into your home. They will refuse to repair any damage caused by their incompetent inspectors. I am extremely disappointed in this company and its owner, Jeffery Donaldson. I will never let this shady business near any of my homes or my clients’ homes. I want to warn everyone to avoid the same painful process I and many others have experienced. There are many other reputable, knowledgeable, and well-trained inspection companies in the Charleston area, such as Cardinal, Hometeam Inspections, or literally ANYONE ELSE besides ACE Preferred Inspections."

Radon Detection and Reduction questions, answered by experts

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

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.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

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.
