Dri Seal was recommended to us by Pro Concrete, who installed our exposed aggregate concrete curbs, walkways, planter boxes, and steps in 2016. We initially contacted Peter in 2018 when we were due to have our concrete re-sealed but we were away for a substantial part of the summer and eventually missed the season when we were ready to proceed in the fall. We contacted Peter in the spring of 2019 and he honoured our quote. He did a quick and professional job.
