Best radon detection and reduction specialists near Fripp Island, SC

Q: Why is my radon mitigation system so loud?

• <div><p>Your radon mitigation system may be loud because it&rsquo;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.</p></div>

Q: What if radon is still high after mitigation?

• <div><p>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.</p></div>

Q: How much does a radon mitigation system cost?

• <div><p>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.</p></div>

Q: Can I perform radon gas abatement myself?

• <div><p>While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.</p></div>

Q: How does radon enter my home?

• <div><p>Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.</p></div>

"Once they started working on it, the work was great. What they did was good, but they forgot to put caulking on one of our skylights. They came back quickly to fix it. We put half the money down and then we didn’t hear anything for 4 months. I guess they were switching company owners, but since then it has been good."
