A garage door weather seal is also called a garage door weather-stripping or a weather seal. The door weather seal is needed for insulating the inside of a room against extreme temperature changes on the outside. It aids in conserving the energy within the garage by reducing its leakage to the outside. This aids temperature maintenance of the garage, helping to prevent weather-induced damage on goods stored within the garage. Furthermore, weather stripping also raises the overall structural integrity of the garage door.

The weather seal should be installed with extreme care since it is prone to getting cracked. This is because it is regularly exposed to temperature-induced contraction/expansion. Furthermore, moisture and vapor from household cleaners act upon its surface, making it vulnerable to wear and tear. The correct way of installing a garage door weather seal is explained below.

Step 1—Getting Started

Using a screwdriver, unscrew the garage door. Place it on a surface that is flat. Preferably, place it on a table so that the underside of the door can be easily accessed. The weather seal is usually laid along the underside of the door. It is recommended that you use a putty knife for scraping-off the paint or wood resin that might be impacted within the old screws. Use a flat-head screwdriver for unfastening the screws.

Step 2—Preparing Weather Seal Installation Surface

Using a hammer and chisel, loosen the old seal (if any). The hammering will loosen the nails/staples, making their removal a lot easier. Unscrew the nails or staples that might be holding down the old stripping. If you cannot remove the old stripping even after repeated efforts, saw off a thin slice of the garage door using a powered saw. Using a tape measure, determine the width of the garage door’s underside. Also, measure the length of the garage door.

Sand the sawed or weather-seal stripped end of the garage door. Using a paintbrush, coat the underside of the door with a wood resin preservative. If you want to strip the sides of the door, repeat the sanding and coating on either sides.

Step 3—Procuring New Door Weather Seal

You can easily buy s strip of new weather seal at any hardware store. The weather-stripping is sold in standard sizes. Ensure that the length of the weather stripping is longer than the measured width of the garage door base. If you want to continue weather sealing along the sides of the door, buy some vinyl weather stripping. This form of weather seal is thinner than the underside door stripping and is sold in standard sizes for garage doors. The vinyl stripping roll’s total length should be more than double the garage door’s measured length.

Step 4—Laying Garage Door Weather Seal

Position the weather strip at one edge of the door’s prepared underside. Secure this part of the weather seal with a nail. Unroll the weather seal strip along the prepared installation surface and secure the nails at an equal distance (work with approximation). Don’t cut the weather stripping until you have reached the other end of the installation surface.

The other option is to staple the strip upon the door using a staple gun. This is a much faster way to secure the weather seal. When you reach the other end of the installation surface, cut-off the weather seal strip using scissors. Use the same method for weather sealing the sides of the door. Here, maintain a distance of about 5 inches between the nails.
