Has anyone else had a bad experience with a Radon contractor? We recently had one who didn't follow the AARST standards https://standards.aarst.org/SGM-SF-2023/ for mitigating radon in our home. They even suggested installing a second system! Luckily, I decided to get a second opinion and found Brian from Purple Mountain Radon https://www.purplemountainradon.com/. He did an amazing job, following all the AARST standards and going above and beyond. He even tackled a small crawl space that required squeezing through a tight opening. He fixed all of the items that weren't done correctly the first time and at a very reasonable rate. Brian is a Veteran and works very hard to do the job right. I highly recommend him!
