Erickson put in a new radon system and sealed my basement cracks. Pre-work, my radon levels were above the dangerous level of +4. After the work it is under 1 and a safe constant level. Also, a part broke ~6mos in and Erickson was prompt to repair at no charge. Justin, their tech, was professional and pleasant to work with. Recommended.
