"I think they did a thorough job, however a small issue with the flashing was missed. It had been caulked which allowed water to seep through the brick. All in all, I had a good experience."

"John was very eager to work around my schedule. Although my husband and I arrived a little late for our scheduled time, he and his team of pros were already hard at work. He was very helpful and courteous. Because the seller had not left the garage unlocked the day of the inspection, John went back out on his own time a few days later to inspect the garage. He went above and beyond and I would definately recommend him to friends. Thanks!"

Radon Detection and Reduction questions, answered by experts

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

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

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

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.
