"Called to ask about getting someone to come check on our radon system, which had stop working several months earlier. The person I spoke with, was friendly and very helpful. She was able to answer a few questions over the phone. She was also able to schedule someone to come out within the week. I was impressed that I received both an e-mail and phone appointment confirmation, the day before the technician was suppose to arrive. The technician showed up right on time, was professional and was able to diagnose the problem quickly. We needed a new fan for the system. Less than 30 minutes later, he was done and everything looks great. He left a radon testing kit that we will use in a week to make sure everything is working. Great experience and would definitely use them again in the future if needed."

"BIG shout out to North Point Radon! We had to re-do some radon mitigation on the house so we could start working on framing in the basement and they came in and did an incredible job. The pressure from the pump (or however you say it) went up from 1.1 to 1.25, so they filled in a bunch of spaces that weren't sealed up properly and cleaned everything up so our contractor can start framing. No big chunks of puffy foam - everything is sealed cleanly and nice and tight now (obvious from the reading on the pressure). Fast, affordable, effective, and we retested the basement and it came at less than 1%. Seriously good people. I would call them if you need any radon stuff (testing, mitigation, etc.) taken care of."

Radon Detection and Reduction FAQs, answered by experts

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

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

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

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

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.
