Before After
Radon Mitigation in Dennison, MN Radon Mitigation in Dennison, MN

Nick M. in Dennison, MN had learned about the dangers of radon gas and decided that he needed to get his home tested. The test results showed a high level of radon. Our Design Specialist walked him through the radon mitigation installation process and answered his questions. Nick wanted to act quickly and moved forward with an installation date. 

Our radon mitigation specialists drilled a hole through the concrete basement to create a suction point for the gas. Then, a PVC pipe is inserted which goes up through the house and exits the home through the roof. A fan is installed at the top of the PVC pipe to ensure that the radon gas is being pushed away from the home. The post mitigation test results showed that his home is now a much safer environment. The installation took only one day to complete, and Nick is glad he took action to protect his and his family’s health.

Job Stories From Dennison, MN
Leaking Basement in Dennison, MN

Cynthia L. of Dennison, MN had water leaking in her basement and wanted it taken care of as soon as possible. After doing some research, she called American Waterworks to schedule a Free Estimate. Our Design Specialist, Dylan Woitas, went to her home and inspected the problem. After a very detailed and thorough diagnosis, Cynthia was comfortable with the proposal, so she went ahead with the project.

To begin the installation, our foreman, Jose Castillo, and his production crew broke out the concrete around the perimeter of the basement floor to form a waterway. Next, they broke out the concrete down the middle of the basement floor to form a feed line to the other end of the basement. On the other end, our crew installed our TripleSafe Sump Pump System in connection with the feed line. Our TripleSafe Sump Pump is the best sump pump we provide for customers and it has three levels of water protection.

Next, Jose and his crew installed 112 feet of CleanSpace around the perimeter of the basement wall. The purpose of CleanSpace is to protect the wall and basement from any mold, mildew or humidity. Lastly, our production team installed 112 feet of our WaterGuard in the trench. Our WaterGuard serves as an underground draining system, prevents water clogs, and catches any contaminated water from underneath the CleanSpace. To complete the installation, our team covered all the open WaterGuard and feed line gaps with rock and replaced the concrete. Cynthia was extremely happy and blessed we were able to help her when she needed it most!
