Close the garage door then place the seal under it without removing the protective cover. Ensure the rubber part of the seal is under the door.

Then mark up the areas that need sealing before removing it.

Carefully apply the seals in a crisscross style.

The let it rest for a day before using the door.

The seals are useful even at blocking dust, dirt, and rain from getting into the garage. An excellent example of the seal to use is Clopay Garage Door Bottom Seal.

4. Seal the Top of the Garage Door

5. Use a Threshold Seal

A threshold seal is also an excellent material to use to seal your garage door. It is similar to the bottom seal only that it is attached to the floor instead of the door.

A threshold is much effective and durable when compared with other seals. It comes with its own adhesive, which means you won’t spend additional money on purchasing a new sealant.

The threshold is made of oak, which is a type of hardwood. The seal helps in keeping things like water from getting in or out of the garage.

Insulating your garage door is also a good way of keeping noise, cold, and insects away. The process is simple and affordable.

Purchase your refereed insulation kits then follow these steps to insulate your garage door:

Measure your garage door then use those measurements to cut the foil but ensure you add a little over an inch. The panels should be large to allow them to convex and curve as an air barrier.

Place the panels on the frame such that the foil is facing the door. Start with the top edge, then followed by the bottom edge.

Repeat the process with the other panels until you have exhausted the panels. Always ensure the panels are of the right size.
