"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.

"Mike did an amazing job inspecting the home I am buying. He was incredibly thorough and took his time he wasn't rushed and didn't skip anything. An added bonus that I really appreciated was how well he explained different things that he noticed in and around the house. I never once felt like I was asking a stupid question when he had to go over something with me. He was very prompt with every question I emailed him and called to follow up on big things. The online report was sent promptly and it was really easy to look through. I would absolutely recommend him to my friends and family!"

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.

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.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

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.
