We recently installed a system for a builder in the Menasha Area. Driving up to the home to pick up the post mitigation Radon test I noticed the home next door also had a Radon vent pipe through the roof. (This builder just switched to us for their systems when needed) I took a picture of just one portion of the system, which was the pipe through the roof to show a comparison of what type of quality work was being installed with us vs. another company. You may have to click on them and blow them up to really see the issues. I will let the pictures do the talking. So, click on the pictures to get a better view. It all comes down to proper training.
