"This company was terrific. The owner, Jason, was very patient, friendly, and thorough during the quoting process, and the company did exactly what he promised in the time promised. Their method of dealing with bowed walls is different from those the other companies quoted me, and was half the price. And it also meant they didn't have to dig up my yard and jackhammer my concrete porch. I did a lot of research because I was worried that it really was "too good to be true." But all the various videos, articles, etc, I found supported that this method works, and the physics of it made sense to me as well. And with the lifetime warranty, along with how accommodating Jason was throughout the entire process, I feel confident that if there does happen to be a problem later down the road, Quackers will make it right. I suppose if they don't, I'll come back to update this review, but so far so good."

Radon Detection and Reduction FAQs, answered by experts

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

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.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.
