"Provided a thorough quote. Told me how to get levels below 4.0 as well as 2.7 which is recommended by world health. Ended up going with 2 points of suction. One in basement floor and the other under the garage floor. 2 techs were sent and the job took about 5 hours. They sealed floors and put a new cover on my sump. Tried to keep the area clean as possible. I swept and mopped after to collect any leftover shavings. Only thing I wasn’t happy about was them walking around the house with shoes on, but I understand as they’re drilling and climbing ladders outside. Would’ve been nice if they removed shoes before using my restroom. Both techs were very nice to deal with and took the time at the end of the job to explain everything in detail."

"As a Realtor, Schan has done many of my clients' radon system install and they all were extremely please with his knowledge, install and his going above and beyond to make the system appealing from the exterior of the home. Many companies will not make the effort to ensure that the system does not look unsightly. Schan does and he is an expert at what he does. I would only recommend Schan to my clients!"

"I consulted with Radon Doctor about my home. The four foot high basement had 5 pci in a 48 hour test. The first living floor was 1.5 pci in the same test. Radon Doctor advised me to monitor radon levels on the living floor over 6 months during winter season and get back to them for mitigation if needed. They did not take advantage of a single basement reading to insist I install a system that would not affect the living floor levels. These guys are legit."

Radon Detection and Reduction FAQs, answered by experts

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

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.

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.
