"DO NOT buy a home until Nate has a chance to inspect it for you. Nate saved me from a bad home buying decision. Nate is very detailed, thorough and documents so well. His report pointed out things I failed to see in my own inspection. He saved me from purchasing a house that needed more work than I even had a budget for the purchase. He is fast, fair and one of the best business people I have met in Casper. I would not go with anyone else for a home inspection. It is the largest purchase any of us make, let Nate inspect it for you and for your piece of mind."

"What a relief to find Anthony and ALO. After a mail-in radon test revealed extremely high levels of radon, we called The Big Guys in town. Do not get me started? .luckily I called ALO next. Their price was MUCH more reasonable and they scheduled me 5 days out! Anthony was great at keeping us informed re: times. He also made it clear that he would start with a basic mitigation package, and if the radon levels were still too high, they would then start adding more expensive fans/additional suction points, etc. There was an up front price list for all these options. Thankfully after 2 days, the work was done and tests soon revealed nearly non-existent radon! I highly recommend these guys."

Radon gas testings FAQs

Radon gas is a serious health hazard, as it is the second leading cause of lung cancer in the United States. When inhaled, radon breaks down into radioactive particles that can damage lung tissue. Because radon is odorless and invisible, regular testing every two years is crucial to detect its presence. If you have recently remodeled or started using different areas of your home, like the basement, additional testing is essential to ensure your family's safety.

Yes, you need a radon test to ensure your home is safe. The EPA recommends testing your home for radon every two years and after any renovations. Since about one in every 15 homes has elevated radon levels, regular testing is essential. Including a radon test in your home inspection is crucial when buying or selling a property, and some areas require disclosure of radon levels by law. Don't rely on neighboring homes or regional data; the only way to know your home's radon levels is through testing.

Certified professionals conduct radon testing, including accredited home inspectors and specialized radon mitigation companies. These experts follow strict EPA guidelines and use calibrated instruments to accurately measure radon levels throughout your home. Choosing a certified provider ensures you receive reliable results that protect your family's health and property.Professional testing is crucial for accurate detection and effective mitigation if needed.

Radon inspectors typically specialize in testing and assessing radon levels but may not perform mitigation services themselves. If your radon inspector identifies elevated levels of radon in your home, they will recommend a qualified radon mitigation specialist to address the issue. These mitigation experts install systems designed to reduce radon concentrations effectively, ensuring your home is safe.

No, air purifiers are not effective in removing radon gas from your home. Air purifiers are designed to filter out particles like dust and pollen, but radon is a radioactive gas that cannot be captured by standard air filters. To reduce radon levels, you need a specialized radon mitigation system that removes the gas from your home, ensuring your indoor air remains safe.

While opening windows may temporarily reduce radon levels by allowing some gas to escape, it is not an effective long-term solution. Radon continuously enters your home from the soil, and relying on open windows is not practical or sufficient to reduce levels significantly. To effectively lower radon concentrations, you need a professional radon mitigation system that actively removes the gas, ensuring consistent and safe indoor air quality.
