"Jack and his crew were thorough, professional and courteous throughout the entire waterproofing project for the basement, which included outside drainage work to better direct water away from the house, and the foundation repairs that were needed. He provided a detailed estimate and explained all facets of the project. Jack also provided additional recommendations for repairing the house gutters and downspouts.
