How to Seal a Garage Door from the Inside: Cover It Properly

Gaps in the garage door may seem harmless until you spend some time inside. Even the smallest gaps are capable of swooping in noise, cold/hot air, and debris. These gaps also affect the integrity of the door and make it difficult to operate. Soon enough, you will see rodents setting up camp in your garage and stinking up the whole place while the garage door keeps deteriorating over time. 

Thankfully, all these problems have one simple solution – To seal the garage door from the inside! The process is as simple as it sounds, and there are multiple ways in which you can do this. We are discussing the most popular and effective ones in this article:

How to Seal a Garage Door from the Inside

Start Seal the bottom with a garage floor seal

This method is ideal if the gaps are at the bottom (of course!), and it is easy to follow too. Get the right floor seal and follow the steps below:

  • Clean the floor to remove any and all dirt
  • Measure the width of your door so that you know how much of the seal to cut. You may need a hacksaw for this.
  • Now, close the garage door and slide the seal (without removing it from its protective cover) under it. The inside of your door should be on the rubber lip. 
  • Mark the area now so that you know where you should apply the seal.
  • Remove the seal and apply it while following the instructions on the seal.
  • Let it rest for at least a day.

Get an insulation kit

If you don’t have an insulated garage door, this method is for you. You can buy an insulation kit that includes a foil for sealing. Make sure you measure the gaps before making a purchase so that you know what size to buy. Once you get the right one, all that’s left to do is to gather the required tools, follow the instructions on the kit, and seal your garage door from the inside.

Use threshold strips

Threshold strips provide a permanent solution to the gaps on the garage floor. All you need is permanent glue and these strips. You can apply them with ease and forget the problem permanently. 

Add weather-stripping 

Weather-stripping is another popular method that can seal your door from the edges. If the gaps are not on the floor, but in the edges, you can use this method. If you already have weather-stripping, you may replace it. Buy the perfect length after measuring and do the needful. The only catch with this method is that it is on the expensive end. However, we think it is worth it because it keeps the wind, snow, and rain out along with pesky rodents, noise, and dirt. 

Use concrete

In the case of metallic doors, which are quite popular today, the concrete sometimes cracks and creates gaps on the floors. So, the easiest thing to do in these cases is to seal them with concrete! This will raise the level of the floor and seal it well from inside. 

A garage door must always be sealed properly without any gaps whatsoever. Even the tiniest gap can make things go bad, especially if your garage doubles as a workshop for you. So, make sure you do the needful with any of these DIY steps. They are all equally reliable and helpful. However, if this comes across as tedious or if you do not engage in DIY projects, you should call an expert. At a small fee, you can sit back and relax as the professionals do it for you.
