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: What is the biggest source of radon?

• <div><p>The soil beneath your house is most likely what&rsquo;s causing an increased level of radon. This is because soil holds radioactivity for a long time and it&rsquo;s also what most buildings are built on. Another common source of radon is water from a source that hasn&rsquo;t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.</p></div>

Q: How often should radon levels be tested to ensure safety?

• <div><p>Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.</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>

Ryan responded quickly by phone and within the week came and started the roof cleaning. Then returned the following week to finish the job. He took the leaves and moss with him but be prepared for the mess it leaves on your vehicles and gravel.
