"In Conclusion,
   the service was on time, professional, complete, and well done. Tom was on time within 15 minutes (which is acceptable to me). He began work without wasting time, while explaining what he was doing at every step. He gave tips when appropriate. He was professional and had all necessary equipement on his person.
I would recommend this service. 
In addition, for an additional $100.00, Homepro will return to make sure that the seller has completed the necessary repairs prior to closing. This feature is useful if you do not trust the seller or selling agent. We did not elect this service, but, it was nice to know that it was available.

Radon Detection and Reduction questions, answered by experts

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

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

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.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

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