I wanted my husband to finish the basement but insisted on testing for radon first, because our son would sleep there. I sprayed it on and my husband caulked one Saturday morning. We have just received our radon results yesterday. The seal created by RadonSeal is permanent. But considering the life of paperwork, we guarantee RadonSeal's performance for 10 years from the date of your purchase , which far exceeds any other solutions.
Radon is much harder to stop than moisture and radon test kits are inexpensive.
We guarantee your satisfaction in terms of reducing radon in your home. RadonSeal must be applied on all basement walls and floors, or the entire foundation slab, following the simple Application Instructions . The guarantee applies for previously unpainted concrete. We gladly provide consultations by email or telephone. If you are not satisfied with the achieved radon reduction, call us first for consultation.
