"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."

"As a first time home buyer, I worked with Scott who did a very thorough inspection and was able to answer any questions I had as we walked through. He had some great equipment that allowed him to perform at the highest standard. Scott was great to communicate with through the process being able to call and text whenever I needed to set an appointment or if I had questions. The inspection report was very clean as clear as well. I definitely recommend Scott and D and S!"

Radon Detection and Reduction FAQs, answered by experts

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

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

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.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

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.
