"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."

"I used Scope Environmental recently to test floor tile and the underlying mastic to determine if either contained asbestos. I selected Scope because Jeff was very responsive, professional, independent of the abatement companies and his price was competitive. Jeff suggested testing both the tiles and mastic. The tiles tested positive for asbestos but the mastic contained no asbestos. As a result, I saved considerable expense by abating the tiles only and not the mastic so I also used Scope again for the post abatement air testing rather than the abatement company. I would hire Scope again for material and air testing for asbestos, mold or any other potentially toxic materials."

"It went great! They set up a system in my parent's house and they mitigated the radon down to a save level. They did a test before and after, and I was satisfied with the results. Proper Environmental did a thorough job and would recommend this company to anyone!"

Radon Detection and Reduction FAQs, answered by experts

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

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

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.
