Mid-Atlantic Waterproofing does one thing and we do it well: basement waterproofing. That includes waterproofing basement, crawl space waterproofing, and structural repairs. A dry basement protects your home and property investment. It prevents fungi that can cause or aggravate respiratory ailments, and it keeps your home safe from water related electrical hazards. We stop the big leaks that leave you mopping and the small leaks that grow into big problems behind the walls.
