"Adam and Nick arrived on time and performed the fan installation quickly and efficiently. The men acted as a team and helped the job to go faster. After seeing how the job went, we asked Adam to look at another project and after hearing his diagnosis and estimate contracted with him to do another job."

"Matt did a great job of installing my radon mitigation system. The unit is set up perfectly and looks very professional and the jobsite was cleaned up to how it was before he started the job. I would highly recommend Matt and Black River Radon for all of your radon mitigation needs."

"My wife and I hired Property Pro to conduct a house inspection during the construction of our new home. We met Justin and he came out several different times during the building phase because we wanted to make sure work was being done properly. Justin was always very professional and honest with his assessment. During one of the inspections he noticed a large crack in the foundation wall and we were immediately able to get it fixed. I believe had he not noticed it, it would have been easily covered up by the contractor. Justin took his time and was meticulous during each visit. He has even remained in contact since the completion of the build to make sure we have had no issues. Most recently we used him again to complete Radon Testing. Again, he was professional, arrived when he said he would be here and then explained the entire process/results when completed. Would definitely recommend Justin to anyone and we will definitely be using his services again as we make upgrades in the house."
