Why St. Thomas homeowners book TriCity.
St. Thomas concrete faces the same enemies as the rest of Southwestern Ontario: road salt, freeze-thaw, summer UV and clay soil that moves. A high-quality solvent-based sealer, applied over properly prepped concrete, keeps water and salt out and colour in.
St. Thomas is a short drive from our London shop, and lakeside properties near Port Stanley benefit from the UV resistance of a solvent-based sealer.
