"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."

"We had a great experience with Justin and his crew. Initially we contacted him to replace some 65yr old windows, and he was the only contractor to bring to our attention that we had hail damage on the window wraps, siding, gutters, and roof. His experience really helped us thru the insurance claim process and it ended up being a huge cost savings for us. We were so impressed with his customer service, we decided to have him convert our 1-season porch into a 3-season porch, install tile flooring, replace some doors, and paint the interior and exterior of our home. He listened to our ideas, gave us options and suggestions, and helped create solutions for all of the projects. He's like a fiduciary for home improvement and we relied on his expertise to make some great choices to improve our home."

Radon Detection and Reduction questions, answered by experts

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.
