Q: What level of radon is considered safe or dangerous?

The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.</p></div>

Q: How do I test for radon gas?

• <div><p>Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.</p></div>

Q: Do radon mitigation systems decrease home value?

• <div><p>No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.</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>

We had Grants Tree Service cut down a 30-35ft tree in our front yard and they were friendly, prompt and price was very fair! They cleaned up after and made the area appear like no one was ever there! Would recommend this company to anyone looking to have a tree cut down!!
