Most problems that occur with showers are completely avoidable and are due to mistakes in the waterproofing process. Not only are the consequences of an improperly waterproofed shower detrimental to your home, they are also detrimental to your health. Moisture trapped in a dark area breeds mold, which can pose a serious health risk. Moisture also attracts destructive insects such as termites and carpenter ants that can do incredible amounts of damage to your home before detection and are costly to exterminate.
