"Radon abatement isn't something you really want to hire someone for, but they did a great job of coming in and disturbing very little while they did the work. Even filled in my couple small crawl spaces to minimize radon from the ground."

"With the recent snow melt and the rain we are having this may be a timely recommendation. I hope you don’t have this need, but if you do I would like to recommend Master Service Company. We had at least six estimates for waterproofing our basement and although not nearly the cheapest, we were impressed by the presentation and the personnel and low key sales approach. So, we hired them! The work was done last week and again we were impressed with the crew doing the work, the care given to hold down the dust created, the quality of the materials used, and the willingness of the crew to keep us apprised of the job as it progressed. The was great care given to cleanup of what is a very messy job. We waited until the repair had been “battle tested”, (and this inclement weather has certainly accomplished that) before writing a recommendation. We could not be more pleased at this point. Again I hope you don’t have the need, but if you do give Mr. Jeff Russell at Master Service a call. Contact: Jeff Russell 317-720-3288."

"It went great! I have a home where the system was not easy to install, but they stayed until it was finished. A test kit was left to see if it was working properly, but they added that they would return if our radon wasn't lowered. IT WAS!! Money very well spent"
