"Todd was very knowledgeable. He answered all questions that I had and even explained what would need to be done to make repairs on things that he found and gave rough estimates of the average costs to make these repairs. I would recommend to friends and family if they we're to need an inspection."

Radon Detection and Reduction questions, answered by experts

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

Yes, many systems include warranties for performance. Confirm terms with your installer.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.
