"I recently used #1 Radon to fix my existing radon mitigation system. I called and Jesse Fuller came to look at system same-day. He had it repaired the same week. He was professional and made me feel comfortable with work and costs to replace the existing fan. I highly recommend #1 Radon and Jesse Fuller."

"From the moment I contacted Jason, until the work was completed, everything was professional. It was a great experience. I did not know anything about Radon, but Jason took the time and effort to teach me about what Radon is and how its mitigated. He went over a few options of how the system can be installed and let me decide which one was best for me. I felt very comfortable with him and felt like he cared about my concerns. He is very knowledgeable and also able to explain things in ways that I can understand. I highly recommend this profesional company and I thank him for his service to this country."

"Called to ask about getting someone to come check on our radon system, which had stop working several months earlier. The person I spoke with, was friendly and very helpful. She was able to answer a few questions over the phone. She was also able to schedule someone to come out within the week. I was impressed that I received both an e-mail and phone appointment confirmation, the day before the technician was suppose to arrive. The technician showed up right on time, was professional and was able to diagnose the problem quickly. We needed a new fan for the system. Less than 30 minutes later, he was done and everything looks great. He left a radon testing kit that we will use in a week to make sure everything is working. Great experience and would definitely use them again in the future if needed."

Radon Detection and Reduction questions, answered by experts

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 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.

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

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.

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