  • Avatar Jon Keller ★★★★★ 9 months ago
    Matt was prompt and did exceptional work. I was impressed by his attention to detail and willingness to go the extra mile. He took the radon levels in my home from 36 pci/l in the … More basement to 1 pci/l when finally tested in our first floor dining room.Our 1875 farmhouse has a sandstone wall basement with 1 foot tall crawlspace. Matt spent an entire day in the 20'x30'x1' space removing rocks with pick and shovel just so nothing could puncture the plastic he was about to lay down. I doubt any other contractors would be willing to work so hard in such a tight space. As you can see from the pictures, he did an outstanding job of sealing off the space although there were several interruptions throughout the crawl where stacks of rock are supporting the floor above.The concrete floor does not have the typical gravel base that allows radon gas to flow freely underneath. Matt installed a strong suction fan and strategically drilled a hole next to the drain pipe that connects both ends of my basement. He believed the outside edge of the pipe would serve as a natural path for the gas to flow towards the suction, and he was right.Matt also took care of little details such as sealing our concrete cracks with silicone, putting down drop cloth in our home, and putting the radon fans in out-of-the-way places. Additionally, he left a T-connection in our crawl space that he can tie into for an upcoming addition. He told us he would come out and hook up the addition for no extra charge.Matt at Black River Radon is highly professional and did the job for a very reasonable rate that we were able to agree on. Getting our radon level down to 1 in our 1875 farmhouse seemed impossible, but he did it. I would recommend him for any radon job.
