How To Soundproof A Garage: 5 Best Methods.

Garage has always been a great place not only for the car and bike enthusiasts but for artists and DIY workers too.

We use it for a variety of works like woodworking, gymnasium, indoor sports, playing drums, etc.

According to a survey by Impulse Research, it was found that around 55% of Americans spend 1-2 hours each week in the garage doing hobbies and other activities.

Are you one of them?

Yes, I guess.

There are few reasons one might consider soundproofing their garage:

  • Artists, while developing their workpiece, dive deep into their own notion of art and any sort of sound coming to their way could spoil the entire mood. For this reason, soundproofing their workspace becomes more important to be more productive on the give up of the day.
  • Another reason which asks for soundproofing your garage is when you work on your motors. It sometimes generates a lot of sound and your neighbors would virtually not reward you for that.
  • Drummers spend a lot of time practicing, which generates a lot of sounds. Hence, soundproofing garage is important to not get scold by your neighbors.

It is very clear that the garage is an integral part of your household, thus soundproofing it is as important as soundproofing any other room in your house.

There are several ways to soundproof your garage. You can cover the door with the help of an acoustic curtain or replace the existing hollow door with a denser one, add acoustic foam to the walls, use soundproof blankets, cover the floor with mats and rugs.

But before knowing on how to soundproof a garage, let us look at some of the amazing facts about the garage.

Astonishing Home Garage Facts 

According to a report by PRNewswire, it was found that 27% of people use the garage for hobbies, while 23% use it to work on cars, 19% in carpentry and 13% of them use it as a gymnasium or indoor sports.

Surprising, isn’t it?

Garage, as by its name, is a place where people work on their vehicles but only 23% of them actually do so.

Another report published on Energy states that according to American Housing Survey, 63% of people were found to have garages at their houses.

A garage is like a second home for you all, so let us look at the ways to soundproof it.

How To Soundproof A Garage 

Step 1: Soundproof Garage Door

Here at Soundproof Core, we always discuss how a door is a major pathway for sound escaping.

So, let us discuss door soundproofing first.

Do you wonder how to soundproof a garage door?

There are different methods to soundproof a garage door, they are:

Seal The Gaps 

Not every fitting is perfect so is your garage door. It contains a lot of gaps which easily allow the interior noise to go out and the exterior noise to come in.

Therefore, to seal those gaps, you need to install weather stripping.

How to apply weather stripping?

Simply remove the protective back of the weatherstrip and apply the adhesive side of the strip along the edges of the door.

Install Fiberglass Pane 

After sealing the gaps, the next thing you should focus on is increasing the density of the door.

Most garage doors are usually hollow, which can easily allow the sound to travel through them.

So, to increase the overall density of your door, you can install fiberglass panels on them.

To attach these panes, you can either screw them to your door or stick them with the help of adhesive.

Hang Acoustic Blanket On Your Roll Up Door 

What if you have a roll-up door? How to soundproof a roll-up garage door?

The above methods won’t work if you have a roll-up garage door.

Don’t worry, I have a way to soundproof it too.

You can use acoustic blankets to soundproof your door in this case.

Stick the blanket to your door with the help of green glue or screw it to your door.

However, it’s not the best way to soundproof the door as the blanket might get caught while opening and closing the door. You would have to remove them every time you open or close your door.

It works well if you are not planning to open your door, but if you do, then it’s not a great idea.

Instead, you can hang the blanket over your door with the help of a hanging rod.

But before buying any blanket, make sure it’s thick because the thicker the blanket will be, the more it absorbs any sound. 

Whether you have a roll-up or a standard door, it’s always advisable to use blankets for soundproofing as it is super cheap and the most convenient way to soundproof your door.

Step 2: Soundproof Garage Window

To soundproof the garage window, you can replace the existing window with a readymade soundproof one.

However, that’s an expensive way to soundproof the window and I would not recommend you to do that.

Instead, I will suggest you some inexpensive ways to soundproof the garage window.

Seal The Gaps 

We have already seen how doors have gaps around their edges.

Similarly, windows too have gaps around the edges and to cover those gaps, there could be nothing better than weather strips.

Weatherstrips, as by their name, are usually used to prevent rain and water from getting in.

But here in our soundproofing world, the major purpose of weather strips is to keep the interior air in or say the sound.

By not letting any air out, it also helps in saving energy on heating and air conditioning.

Install A Second Layer Of Glazing 

Windows in modern houses are generally made of single layer glass panes which is not efficient enough to block the noise passing through them.

To increase their density, you can add a second layer of glazing which will not allow the sound to penetrate the window.

Keep a gap of 6mm while applying the second layer, as it will offer strong sound insulation by having a decoupling zone between the two layers of the window.

Hang Soundproof Curtains 

If your pocket doesn’t allow you to spend on glazing, then you can go with acoustic curtains as they are relatively cheaper than glazing.

However, this will prevent you from looking at the view outside the window and your neighbors from looking at your beautiful garage.

You have to compromise between the view or your budget.

Are soundproof curtains good enough to insulate sound?

Yes, for a person who cannot spend a large amount of money on a new soundproof window, curtains are very effective in blocking out unwanted sound.

Step 3: Soundproof Garage Floor

You also need to treat your floor while soundproofing as sound bounces from the floor to the walls and ceiling and back to the floor, giving rise to an echo effect in the garage.

Soundproofing the floor is the easiest step, as it requires putting only some carpets on it.

Look into your storeroom first. Who knows, you may already have some old carpets stored there.

How about using gym mats in your garage?

Gym mats are very thick and thus are very good at absorbing sound.

If you are not new to soundproofing, then you would know how the thickness of a thing matters in soundproofing.

In the garage, you have heavy tools and any of them falling on the floor will surely deface it.

So apart from soundproofing gym mats, also protect your floor from getting damaged.

It will be useful for those too who use their garage as a gymnasium.

You can also put some blankets over the mats to absorb more sound and it will also give you a satisfying furry feel.

Step 4: Soundproof Garage Walls 

Garage walls are generally thin, allowing more sound to pass through them.

You are never out of option while soundproofing a wall.

It depends on what are your requirement and budget.

Lets us look at the various methods to soundproof a garage wall.

Seal The Gaps 

Before taking any major project on your wall, the first thing you should do is to fill the gaps in the wall.

I know it’s the third time I have said you to fill the gaps, but doing so is necessary as tiny of these gaps can make a vast difference.

Do you know?

Caulking can help you reduce the amount of noise in your garage by almost 15%.

To fill those gaps, what you need is green glue.  

It is a viscoelastic damping compound that converts sound energy into heat energy.

Install Acoustic Foam Panels 

acoustic foam

The idea behind soundproofing is to add density and to do that, what you could do is to add acoustic foam panels to the walls. Acoustic foams are made of a material that absorbs sound.

They are mostly used in recording studios to improve the vocal quality of the artist while recording.

But that doesn’t mean you can’t use them in your garage.

They can also give your garage an attractive look if used in different styles and colors.  

Install Drywall

When it comes to soundproofing a wall, dry walling is one of the best known options.

What is drywall?

Drywall, also called plasterboard or wallboard, is a flat panel made of gypsum plaster, a sulfate mineral, stuffed in between two thick sheets of paper.

Installing 5/8-inch drywall will be very useful in deadening the amount of noise in the garage.

No, it’s not expensive, it only costs about $1.5 a square foot.

Besides its soundproofing capability, drywall also has excellent fire resistance properties, so you don’t need to worry about accidental fires in your garage.

Drywall is even easy to decorate.

You can draw something or stick wallpaper to it, to increase the overall aesthetics of your room.

Acoustic Blankets 

Now, a more cheaper but effective solution to soundproof your garage walls is to add acoustic blankets to them.

We have already seen how thick blankets are very good at absorbing sound.

So, it makes sense to use them on your walls too.

Now, how to install a blanket on the wall?

You can either screw the blanket to your walls or if you are concerned with not damaging your walls then you can hang the blanket in front of your wall with the help of a hanging rod/wire.

However, adding blankets to the walls certainly doesn’t look good.

You need to make a choice between the budget or the looks.

Step 5: Soundproof Garage Ceiling 

So, we talked about the door, the window, the floor, and the walls.

But what soundproofing garage ceiling?

Though sound, don’t travel upward like the heat, but you need soundproofing your ceiling to make your garage more soundproof.

Let’s look at the two methods to soundproof your ceiling.

Use Acoustic Foam 

You can stick acoustic foam to the ceiling to reduce the amount of noise in the garage.

The pyramid and wedge shape of the foam does not allow the sound to bounce through them and thus reduces echo in the room.

You can use green glue to stick these panels to your ceiling.

Use Acoustic Blankets 

A cheaper alternative for foams is an acoustic blanket.

Blankets are no less than acoustic foams in terms of absorbing sound.

But be careful while buying a blanket as thick blankets are better at sound absorbing than thin blankets.

To install the blanket, you can simply nail it to your ceiling.

How Much Does It Cost To Soundproof A Garage 

Whether you want to insulate the motor sound or wish to turn your garage into a recording studio, the most obvious question you ask is how much does it cost to soundproof a garage.

The answer to your question depends on the degree of soundproofing you want to have in your garage. It depends on what of the above steps you are going to follow.

But for an instance, the cost to soundproof your garage could be anything between 1500-3500 USD.

I have mentioned cheapest way to soundproof a garage, so don’t worry.

I would like to answer some questions about soundproofing a garage.

If you also have these questions in your mind, then I would recommend you to read them below.

Q1. What is best for garage walls, plywood, or drywall?

When it comes to garage walls, drywalls are always better than plywood.

Drywall is the most cost effective and most noise reducing when compared to plywood.

Plywood has very poor soundproofing quality as sound transfers easily through the wood.

Besides its cost effectiveness and sound proofing ability, drywall also offers excellent fire resistant property, preventing the garage from accidental fire.

Q2. Do egg cartons absorb noise in a garage?

No, egg cartons don’t actually help you reduce noise in your garage.

They may deaden some amount of noise by absorbing sound waves, but aren’t helpful to effectively soundproof your garage.

The only thing they help you in is to reduce echo in your garage.

But, is it worth it, sticking them on your garage walls just to reduce echo?

No, I guess.

And also, they will destroy the aesthetics of your garage.
