Weatherstripping is both a way to protect the interior of your garage from flooding in addition to improving the overall insulation of your home. In the summer months, weatherstripping keeps cool air in. In winter months, weatherstripping keeps water and rain out, while stabilizing the home’s internal temperature.
While it is advisable to seal the door connecting the garage to the main living area of the house as well, properly installed weatherstripping around the exterior garage door can help to greatly reduce the risk of lost energy. Additionally, the bottom of the garage door will not scrape against the concrete or pavement, helping to prevent premature wear of both the door and the floor. The cost of installing or replacing weatherstripping is low, especially when compared to the long-term benefits it provides.
