"adon After I contacted him, he responded promptly.  While evaluating the area that needed radon mitigation, he called to discuss an area that had not been evaluated by inspectors (not affiliated with him).  After accepting his price, we agreed on the day for the installation.  During the installation, he was respectful and communicative.  After completing the installation, he provided written warranties for me and the buyer.  I highly recommend Keystone Radon Mitigators.

"Neil is fantastic. Similarly to my last experience with him, he was prompt and professional. He had his septic resource properly scheduled, whom came out and did the septic test on time and were great to work with. He again explained everything as he went along, and again got the main home inspection report back to us the same day! He did a larger battery of tests than last time for us, and all results came back in a few days and were explained to us. Again, he offered his services to answer questions unrelated to home inspection if the need arises. We also had some concerns over some attic insulation, which he had tested for asbestos free of charge. I would highly recommend Neil!"

Radon Detection and Reduction FAQs, 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.

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.

Installation typically takes 1-2 days, depending on the system and property layout.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

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