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

• <div><p>No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely.

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 often should you replace a radon fan?

• <div><p>Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.</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>

"April helped us line up a last minute inspection for a new build for us. They were extremely thorough and found a few significant problems that we were able to take to the builder. They included lots of photos of the issues which was helpful. They used thermal imaging too which was new to us but helps detect problems that may not have been seen otherwise. We got our report along with a summary the next day and had excellent communication and follow through. We will definitely use them in the future and highly recommend."
