"Black Dog clearly explained the radon problem in the house and the proposed mitigation plan. He was professional, knowledgeable, and a pleasure to deal with. We explained to Eino Anttila our concerns about having the high radon levels while our infant grandchild would be visiting from out of state and he went above and beyond to install the mitigation system before they arrived. He was able to reduce the high radon level to an acceptable level. He even monitored the mitigation system in our house while he was on vacation out of state and sent us reports. We highly recommend Black Dog Inspections."

Radon Detection and Reduction questions, answered by experts

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.

Short-term tests take 2-7 days, while long-term monitoring may require up to 90 days for accurate results.

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