ABOUT RADON
Radon often goes undetected in homes & offices around the world. It is radioactive, cancer-causing, and is present nearly everywhere on earth. The only question is, how much are you breathing every day? The only way to find out is by properly testing for radon in your home or office.
Radon testing can be performed in several different ways, with advantages and disadvantages to each.
SquareOne Radon encourages everyone to test their homes whether opting for one of our professional tests, or a consumer-level test from a local hardware store or online source.
The important part is knowing--and managing--your risk level, and we're here to help with that.


ABOUT SquareONE
SquareOne Radon is a local radon testing and mitigation company founded on the principles of ethical business practices, professional integrity, quality workmanship, and bettering the health and safety of the communities in which it operates.
SquareOne stands apart from the competition in many ways including utilizing the most scientific and calculated approaches to providing radon testing and mitigation solutions. Precise measurements to determine and document air flow, air pressure, pressure field extension, and more are routine practice at Square One. Unfortunately, many radon companies do not invest in the tools, training and techniques required to provide the most effective and efficient solutions to radon problems.
SquareOne Radon was founded with the vision of offering the most advanced, reliable, and proven testing and mitigation technologies to residential and commercial clients including homeowners, businesses, schools, contractors, and real estate professionals.

Square One did a radon test in my home. The test was performed in a couple days and I had results immediately. Well worth it for peace of mind. The owner is extremely professional and knowledgeable. Highly recommend this company.

Rob called on my request for remediation immediately, and by the way, no other radon company called me back...Square One scheduled to look at the project right away and was timely with the estimate...the work was performed efficiently and with the least visible "intrusion" as possible.
