Best radon detection and reduction specialists near Cottage Grove, OR

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 long does a radon mitigation system last?

• <div><p>The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.</p></div>

Q: How is radon gas abatement professionally handled?

• <div><p>Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.</p></div>

Q: What types of radon mitigation systems are available?

• <div><p>Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.</p></div>

Q: What steps should be taken if high radon levels are detected?

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