It was such a pleasure having Derek take care of the concrete and interlock around our home. From the start, he was very responsive and clear about the cost and timeline. You can see he cares about doing things right. We are so pleased with the service Derek provided as well as the quality of work. He cleaned, re-sanded, and sealed my interlock pavers in my backyard, as well as cleaned and sealed two areas of patterned concrete. Derek took care to make sure no sealant went onto our deck, and used quality products. Delighted to recommend PowerSeal to anyone. A high quality job from a really nice man.
