While renovating a 1949 house, we discovered drainage problems with a sidewalk than ran alongside the house. Alex's crew removed the old sidewalk and poured a new sidewalk that allowed water to drain away from the house and then down the driveway to the street. We decided to replace the back patio and porch stoop at the same time. In addition, we asked them to remove the concrete steps from the front porch and add a new sidewalk, steps and small stoop for a new entry into the house. The guys at Alex Construction did an outstanding job. All the new concrete is appropriately sloped to direct water away from the house and Alex had them add a little extra depth to the edge of the sidewalk to prevent rainwater from migrating under the walkway and entering the crawl space under the house. The walkways, steps, porches and patio look great and in hindsight I probably should have asked them to replace all the old concrete walkways in the backyard. Big improvement in the appearance of the house exterior. The crew cleaned up all the grounds and even replaced some soil and sod along the edges of the patio. It was a pleasure to work with some real professionals.
