No, not all water main pipes are coated with epoxy. Many older homes and buildings have uncoated copper, galvanized steel, or PVC pipes. Epoxy coating is typically applied as a rehabilitation method—not a standard installation—when pipes begin to corrode, leak, or show signs of wear. At Done Plumbing, Heating, Cooling & Electric, we use epoxy and polyurea coatings as a strategic solution to extend the life of aging water mains without digging or replacing the entire line.
