We are extremely happy with John's work. He installed a radon mitigation system for us in January 2017 and it reduced our radon levels from 360 Bq/m3 to 22 Bq/m3. During the initial assessment he took photos, made notes and gave as a quote, which was competitive, and he performed the work for the quoted amount. He completed the majority of the work in a single day, with only a few items left for subsequent days. Having been involved in home construction, John really knows his way around the hidden infrastructure of houses. Our house was built in the early 60's and he was familiar with the construction practices of the time, so was able to quickly determine the best placement for the system and get it working.
