What Parts Of The Garage Door Do I Seal?

Garage doors can have gaps caused by a variety of reasons. Let’s take a look below at why a garage door could have a gap.

  • Door Panel weatherstripping – This material will seal gaps between each garage door panel. Older wood garage doors with flat edges can benefit from this type of seal. Additionally, this weather stripping attaches with self-adhesive. So, it is easy to install, and as the door closes they press against the seal keeping it airtight.
  • Door Stop weatherstripping – These are installed on the garage door sides and the top of the garage door. Their purpose is to keep the rain and wind out of the garage. This type of weatherstripping comes in roll form and you can cut it. Use a utility knife to cut the strips to the required length and use galvanized nails or screws to install the strips.
  • Threshold Seal – This type of seal is installed on the floor of your garage. The main purpose of a garage door threshold seal is to redirect rain from the bottom of the door toward the slope of the driveway. The threshold seal works in tandem with the garage door seal.
  • Door Bottom Seal – The garage door bottom seal is a piece of vinyl or rubber stripping. When this seal becomes warn you will see sunlight coming into the garage. Since this seal is at the bottom, it is important that you keep dirt, debris, insects, water, and critters from being trapped under the bottom door seal. These seals are easy to install and have the best functionality.
  • Viny Door Stops – This vinyl strip is a combination of weather-seal flanged and wood-look molding strips. You can use galvanized steel siding nails to install these door stops. Place each piece parallel to the face of the garage door. Be sure to push the molding so that it seals against the door. Next, nail or screw the molding to the door jamb. Always install the top first and then the sides.
