"Buyer Beware!!! Once the installation is complete, you're on your own. I own a digital radon detection device. It's been over a month since the installation and the radon levels are above recommended levels (4/20/23 4.4, 4/21/23 5.2, 4/22/23 4.2, 4/28/23 6.4). I didn't monitor it every day but today it's at 4.3. When I contacted John the owner on 4/19/23, he suggested two options. 1. Install a larger fan for $150 which he said may or may not work and 2. Call some company to come out to run a scope to see if there is a blockage. He couldn't suggest a company because he didn't know any. The one option he didn't offer which I suggested, was to have one of his technicians come out to take a look at it. Needless to say I am not a happy customer. I paid $1,300 for something that doesn't work with no recourse. I will be contacting the BBB though."

Radon gas abatements FAQs

You need a professional radon test to determine if radon is present in your home or water. A qualified radon inspector can provide accurate measurements, costing between $150 and $800. This information helps you decide on the necessary steps to remove radon from your home when you hire a professional radon mitigation company.

Radon inspectors and radon treatment professionals have distinct roles. Inspectors measure radon levels and assess your home's risk, while treatment professionals install systems that reduce radon concentrations. In some cases, a single expert may perform both functions; however, each responsibility requires specific expertise to ensure accurate testing and safe system installation.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reduce radon levels reliably.
