"Everything went well. The repaired cracks have not leaked during recent storms. In addition, the radon test results after

the mitigation system was installed showed it is working and the radon in our basement is now at a very low level."

"As a first time home buyer, I worked with Scott who did a very thorough inspection and was able to answer any questions I had as we walked through. He had some great equipment that allowed him to perform at the highest standard. Scott was great to communicate with through the process being able to call and text whenever I needed to set an appointment or if I had questions. The inspection report was very clean as clear as well. I definitely recommend Scott and D and S!"

Radon Detection and Reduction questions, answered by experts

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

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.

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

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

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