Testimonials for National Radon Defense Admin

Great results! Our post mitigation reading was below 0.8 pCi/L. Now we can rest assured our basement air is safe to breathe! Technicians were both professional and knowledgeable. I would recommend you to others.
Bryan K. of Plymouth, MN
Thank you! Our post mitigation results were great. I was impressed with your two installers, knowledgeable and neat workers.
Millie H. of Cascade, IA
I just received the results of the radon test conducted about a week after the mitigation system was installed. I couldn't believe the reading was so low. I am very pleased with the results and now look forward to being able to spend lots and lots of time working on my trains again. I didn't know if I had to report these results to you or not, but here they are anyway. Again, thanks for everything that was done, and so expeditiously.

I wanted to let the company know what an excellent job you and Jan Matos did with the installation of my radon mitigation system. I appreciated your professional advice and prompt follow-up. Juan did and excellent job! He was very professional in answering my questions. When he was finished, everything was back and cleaned up (probably cleaner). He represented Thrasher Basement Systems very well! I will definitely recommend your company to others! Thanks again.
Pam E. of Geneva, NE
Your company, with all representatives I've been involved with, are truly exceptional! No thought was ever given to another company. I selected Thrasher mainly because of all the "WOW's" from a previous encounter, not related to radon. Curt suggested the cover for my sump pump. I am extremely happy with the results. It was essentially what I was hoping for when I had your rep here before, though I think I was asking about a new sump pump. I didn't know about the alternative until Curt suggested it. I'm sure it will help reduce the pesky sump pump odor!

"Ted and I really enjoyed the NRD training last week. Your system is incredibly thorough and we are excited to get started on this new addition to our business. You have given us all of the tools we need to get going immediately . Parts of your system will even help us with some aspects of our foundation repair business. Thanks so much for all of the information and helpful tips."Ted & Barb
