"This job was completed efficiently and professionally. A design specialist came to test and measure every detail for the project. The crew arrived with everything needed for the job. They worked very hard to install Waterguard in the concrete floors inside around the foundation to the sump pump basket. They also installed Geo-lock anchors to support a block wall that was bowed. This company has 36 years in business and provides excellent results and professional customer relations. Call Amer. Wtrwrks for a free estimate. You will not be disappointed. A wise investment of $11,270."

Radon Detection and Reduction questions, answered by experts

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

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.

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

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

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