    The work itself was adequate, but there are several things prospective customers should know before…read morebooking. Most importantly: be very specific about where you want the system installed and do not defer to their suggestions. These systems are large and not particularly attractive, so if concealment matters to you, be firm upfront. A few specific issues I encountered: Pricing: STL Radon is booking several months out. When the tech arrived on installation day, my quote increased by $200. I was told I could cancel, but rebooking with another company would mean waiting several more months -- not much of a choice. Installation day: I gave permission to use my garage but asked twice that the door be kept closed when not in use (I live in the city and prefer not to advertise an open garage). The request was flatly refused. Placement: I specified where I wanted the system installed. It was placed next to my breaker box and sump pump instead, with the exhaust pipe now exiting directly by my deck. When I asked why, the tech said they assumed my basement was finished -- it is not; it's a rubble foundation with no finished space whatsoever. Resolution attempt: When I contacted the company, they offered to relocate the system only if I paid the outstanding balance in full plus an additional $1,000+. I wasn't asking for a discount -- just for what I originally requested. To make matters worse, they attempted to add late fees before the installation was even complete (it had been paused due to wind). When they returned to finish, they gave a window of 11:30-1:30 and only showed up after I texted to ask if they were still coming after 4:45pm. I'm not saying avoid them entirely, but go in with your eyes open and get everything in writing.

    Cherie is absolutely fantastic and has been demonstrative in helping me understand the health risks…read moreof increased radon exposure, explaining how cost-effective it is to get testing, and easy way to alleviate any potential issues from elevated levels.
