We all know how annoying the noise from the outside can be, either because of a lot of traffic or a busy neighborhood.
One of the most important things to do in order to avoid that is to properly set up your doors and windows, as well as having some sound isolation in the walls.
Today I’ll talk about how you can fix the noise issue by fixing the gaps that exist on your garage door, which can be achieved in different ways.
So, if you are interested to know more, make sure to stick with me until the end. Now, before we start, you will need several items, I’ll list them below:
How to Seal a Garage Door from the Inside
Sealing the Garage Door Bottom
Let’s start this guide by learning how to seal the bottom part of the garage door. Before you do that, you want to check if they even need sealing.
The best way to do that is to go to your garage during the day, turn off the lights and if you see the light coming from the bottom side of the garage door, you definitely need to seal it.
There are several ways to do that, but the two most effective are using the floor seals or using the bottom seals.
1. Using Floor Seals
The first trick you can use, in order to seal the bottom cracks of your garage door is to use floor seals since they are extremely simple to use and they don’t require a lot of effort to install.
Apart from being very effective against the light and noise, garage door floor seals are pretty useful against other annoyances, such as vermin, dirt and they can be very useful if there is bad weather as well, since they can stop that strong wind and rain from coming into your garage.
Floor seals are quite similar to acoustic thresholds that people use to make their front door soundproof and they are usually made of rubber.
Let’s see the instructions on how to set up floor seals on your garage door:
- Make sure to completely clean the floor, so it is perfectly clean, without dirt or anything else that might have a negative effect on the whole process.
- Take the right measurements, so you could cut the floor seal to fit perfectly to your garage door.
- Now, first, close the garage door and make sure to take the seal and put it down on it, by placing the raised rubber lip against the inner side of the garage door, while positioning the seal’s thin size under the door.
- The next step is to use chalk or a pen of some kind and mark the spot where the seal is going to be on the floor.
- After that, make sure to move the seal and cover the space on the floor in a specific crisscross-like way.
- The last step is to wait for the seal to become firmly glued, for a day or so.
2. Using Bottom Seals
Another way to seal the bottom of your garage door is to use bottom seals, which are seals that are shaped like letter U and they are easily installed, since they can simply clip into the right place, meaning that you won’t have to use any screws or special glue.
Same as before, what you want to do first is to measure your garage door and cut the seal to fit its size, after which you should simply put it on the bottom side of the door.
Sealing the Garage Door Top
In order to completely isolate the noise and other effects from the outside, you will have to, not only seal the bottom of your garage door, but also the top side of it.
The best way to do that is to get a garage door top seal, which is a strip completely made of rubber that is used to seal the top side of the door to the ceiling when the garage door is fully closed.
This is not only useful for soundproofing but also to keep your garage warm during the cold winter days, since hot air usually rises to the top of any object or room.
By using the top seal, you can prevent that hot air to leave the room or object, thus keeping it inside and making the garage warmer.
Apart from just protecting the top and bottom sides of the garage door, you should also think about sealing the sides of it, since vermin, insects, noise and dirty air can also come through there.
Gaps that can happen on the sides of your garage door might be the result of aging, as well as not so good fitting.
The easiest way to seal your door and protect it from the outside influence is to use weatherstripping seal, which can be set up in a really short time, without too much trouble.
Of course, first, you need to get some weather stripping seals for universal use, amongst which is for sealing the garage door and make sure to take the right measurements so you know how much of the weatherstripping to cut later.
After that, apply certain rubber adhesives, for example, Sikaflex 1A from Sika and use it to glue the weatherstrip to your garage door.
Make sure to close the garage door, so it could press the weatherstrip. That way, it will stay firm for a day and ensure that the strip stays on.
Also, make sure that there is no glue in the actual garage door because it could rip the seal the first time you open that door.
Insulating the Garage Door
A more advanced method of making your garage door soundproof is to do complete door insulation, which would not only make your garage quieter but also, much warmer during winter and much cooler during summer.
When it comes to the insulation process, it is very simple and not really expensive, since it costs around $200 dollars to do it for the two doors, which are 9ft in length.
Insulation Types for Garage Door
There are several types of garage door insulations. All of those are pretty effective when it comes to reducing power consumption and noise isolation, but let’s find out what are the differences between them:
