If you’re a homeowner, then you probably don’t have much choice but to live with the sounds of your garage. But if you’d like to soundproof your garage and make it more enjoyable to work in, or you want to use it for band practice, workshop or storage, here’s what you should do.
How to Soundproof a Garage? Use Mass Loaded Vinyl Sheets to insulate your garage walls. Hang soundproof blankets on the walls of your garage to reduce the amount of sound that comes in and out of the room. Build a sound maze inside your air vent to block out the noise from your air vents.
Garages are notorious for being hard to soundproof. Acoustics tend to be a big problem when it comes to soundproofing garages since they’re large and unventilated, as well as suffer from small changes in floor height.
This article will talk about how acoustic noises are generated in garages, and what can be done about this issue.
How to Soundproof a Garage – What are the ways?
Insulate the walls, ceiling and floor of the garage with foam or fiberglass insulation. Hang thick curtains on all sides of the door between your garage and your house. Install solid doors that are made of fiberboard or plywood instead of hollow-core ones.
That is a short answer, read below to get more information on all these methods.
Here are some ways to soundproof a garage so that it’s comfortable for both you and your neighbors:
1. Add Mass to the Wall using Mass Loaded Vinyl
Adding mass to the walls of your garage is one of the best ways to soundproof it. This is because adding mass adds weight, and generally heavier objects don’t vibrate as much as lighter ones.
The main benefit of adding mass is that it will help prevent sound from entering or leaving the garage. The heavier the materials used, the less likely they are to vibrate and bounce sounds around.
One way to soundproof a garage is to add mass to the walls using mass loaded vinyl. This is a great option for people who want to do something that is both affordable and easy.
Mass loaded vinyl is a type of material that can be applied to the wall in sheets, and it will absorb sound, making it much quieter inside your garage.
2. Hang Soundproof Blankets on Wall
Soundproof blankets are made from dense, thick materials that absorb sound waves. They’re typically made of fiberglass or foam and can be woven into fabrics or used as a solid sheet. The blanket is typically applied to the walls of the garage using adhesive tapes or nails.
The primary benefit of using soundproof blankets to soundproof a garage is their low cost. Compared with other methods of soundproofing, such as filling in the walls with insulation, this approach is much more affordable.
The second major benefit is that it’s easy to install. You don’t need any special tools or skills. All you need is common household items like tape and a hammer (for hanging up the blankets).
3. Build a Sound Maze for Air Vents
A sound maze is an easy way to reduce the noise from a garage door. The idea is that if you build a labyrinth-like structure out of plywood and fill it with foam, the sound waves from your garage door will bounce off of all the different surfaces, creating a muffled effect.
Here’s how to build one:
- First, take some measurements for your plywood (you’ll need two pieces). Then, cut those pieces out with a saw.
- Next, use sandpaper or another abrasive material to smooth out any rough edges on your plywood pieces.
- Put the first piece of plywood on the floor in front of where you’ll install your door vent. Then place the second piece on top of that one so that they form an upside-down “V” shape (with plenty of space between them). This will be your sound maze.
- Once you’ve done this, stand back and look at it, does it look like a maze? If not, try angling one piece more than another so that there are more paths through there than just straight lines.
- Now go ahead and seal up all those nooks and crannies with caulk. Use enough so that no light shines through any gaps.
Quick Tip: Add the foam insulation to the two pieces of plywood for better soundproofing.
4. Seal any Gaps or Cracks
To soundproof a garage, you’ll want to pay special attention to the gaps and cracks in the walls, floor, and ceiling. If you have any gaps or cracks, they’re probably the main source of noise in your garage.
You can use foam or caulk (preferable acoustical caulk) to seal up those areas. Or, if you’re looking for something more permanent, you can use spray foam insulation.
This type of insulation is made from polyurethane foam that expands over time once it’s sprayed onto surfaces. It fills in all of those pesky gaps and cracks that can let sound through.
Seals Cracks and Gaps in Garage Door
A garage door is typically made of two panels: one that’s fixed, and one that moves up and down. The moving panel has two tracks on either side that it rolls along.
Those tracks are connected to the fixed panel. When these panels are connected, there should be no gaps between them, but often there are.
The best way to check for gaps is to shine a flashlight along the edges of your garage door while it’s closed, then open it and check again (make sure you’re not looking at light sources).
Any cracks or gaps you see can be patched with caulk or sealant specifically designed for this purpose.
Seals Cracks and Gaps in Garage Walls
The first step is spotting the cracks and gaps you want to seal. You can do this by shining a flashlight along the walls, or using an infrared camera. Either way, you’ll be able to see where heat escapes from the garage and sound makes its way through.
Once you’ve found the gaps, seal them up with spray foam insulation or caulk.
5. Weatherstrip the Garage Door
One of the biggest problems with garages is the sound that escapes and comes in through the spaces around the garage door.
The solution is to install a heavy-duty weatherstripping around the entire perimeter of your garage door. This will reduce both noise from outside, as well as any noises coming from inside your garage.
To properly seal your garage door, use foam weatherstripping that is at least 1/4-inch thick. If you’re worried about how it will look, you can get foam that matches the color of your garage door.
6. Hang Acoustic Panels
Acoustic panels are a great way to soundproof a garage. They absorb sound waves, which makes the space quieter, as well as reducing noise from both inside and outside. These panels are made from special materials that make them ideal for this purpose.
Acoustic panels are made from dense materials that absorb sound waves so that they don’t bounce around and cause reverberation.
They’re typically made of foam or fiberglass, which makes them lightweight and easy to install. You can stick them with double-sided tape or glue, or use screws if they have holes in them.
Hang Acoustic Panels from Ceiling
To hang acoustic panels from the ceiling, first measure out where you want them to go. Then use a stud finder or hammer to determine where the ceiling joists are located (studs are usually every 16 inches apart).
Next, screw in drywall anchors into each hole. These will hold up all of your panels as you work with them.
Now place your panel in place over one anchor so that it’s snug against both sides of the anchor. Place another anchor on top of this one so that it sits directly over top of it and holds down both sides at once (this creates more pressure than just having one anchor per side).
Hang Acoustic Panels on Walls
There are a few different ways to hang acoustic panels from the walls.
- You can use nails and screws, which is the most common method. You’ll want to make sure that you’re using drywall anchors if your walls are made of drywall, because it’s not as strong as concrete or wood. Drywall anchors will give you extra support while holding up the panels.
- Another option is to use Velcro strips instead of nails or screws. Velcro is great if you’re going for a sleek look, but it can be difficult to install if you don’t have much experience installing things on walls.
- The last option is to use glue dots, which are small circular disks that stick onto the back of each panel when placed correctly against the wall. These are great for people who have difficulty hanging things up with nails or screws because they’re easy to remove if necessary.
7. Insulate the Walls
Soundproofing insulation has been proven to be an effective way to reduce noise in a garage, so if you’re trying to soundproof your garage this is a great place to start.
The benefits of insulating a garage are numerous. You’ll find that your garage will be warmer in the winter and cooler in the summer, saving you money on your energy bills.
You’ll also find that the noise level will decrease significantly, making it easier to work on projects or store things.
And lastly, you’ll find that your garage will be more comfortable to spend time in, which is something we all want.
Insulation can be done with a variety of materials. Following are some of the most common types of insulation you can use:
Batt and Roll Insulation
Batt and roll insulation is a type of fiberglass insulation that can be used for soundproofing. It is made from a number of layers of fiberglass, which are compressed together to form a sheet.
This sheet is then wrapped around the outer walls of a room to reduce sound passing through it.
The thickness and quality of the batt and roll insulation will determine how effective it is at reducing noise.
The loose-fill insulation is not compressed or packed into a container. It can be blown into a space through an opening or hose, or it can be poured into the space from above.
Loose-fill insulation made of fiberglass, rock wool, and cellulose is often used to insulate walls and ceilings.
Reflective insulation is made of metal fibers. It is not a very popular option because it’s expensive and it can be difficult to install.
It is made of reflective material, which reflects the sound waves back into their source. This type of insulation is very effective in blocking out noise from outside sources like traffic and neighbors.
This type of insulation is most effective when applied to the walls. When applied to the ceiling, it helps to reduce noise coming from above.
Spray Foam Insulation
Spray Foam Insulation is made from a mixture of chemicals that are sprayed onto walls, ceilings, and floors to seal them against noise.
The foam expands to fill all the gaps between the building materials, creating a barrier that keeps outside sounds from getting in and inside noises from getting out.
The main drawback of spray foam insulation is the cost. It’s more expensive than other types of insulation. But if you’re looking for something that will do double duty as a sound barrier, it’s worth considering.
8. Add Resilient Channels
If you’re looking for a cheap way to soundproof your garage, think about using resilient channels.
Resilient channels are made up of galvanized steel. They are a great way to reduce the amount of sound that gets into your garage and keeps it from rattling around in there. The best part about resilient channels is that they don’t cost much at all.
Resilient channels are attached to the studs and joists, and they allow the gypsum wallboard to float away from the framing. This floating action also helps to provide soundproofing, as well as leveling any unevenness in the framing.
9. Use Sound Absorbing Paint
Sound absorbing paint is made from a substance that absorbs sound waves, rather than reflecting them back into the room as other paints do.
This means that when sound waves come into contact with the paint, they are absorbed and don’t bounce back out again. Instead, they’re absorbed into the wall itself. This keeps noise from rattling around your garage.
This is not the most effective method for soundproofing, but it can help to absorb some of the noise. It is best to use this method in conjunction with other methods.
10. Use Floor Sealers
Whether you’re trying to soundproof an office, bedroom, or garage, floor sealers can help you cut down on the amount of sound that gets in and out.
Floor sealers are applied to the floor of your garage, which helps keep sound from coming into the room from below (such as cars driving by), and they also keep the noise from leaving through the ceiling. This can be especially helpful if your garage is in close proximity to other rooms of the home.
A good quality floor sealer will not only prevent the transmission of sound, but it will also help prevent water from seeping into the concrete or asphalt.
Here, how you would apply the floor sealer on your garage floor:
- To apply garage floor sealers, start by sweeping or vacuuming your garage floor to remove any dirt or debris.
- Next, cover any areas you don’t want sealed with painter’s tape or blue tape.
- Then pour a small amount of sealer into a paint tray and use a paint roller applicator to spread it evenly across the floor in one direction (from side-to-side).
- Allow the sealer to dry for 24 hours before using your garage again.
11. Double the Drywall
Double drywall construction is a great way to soundproof your garage, because it’s easy to install and relatively inexpensive. The key is to use two layers of drywall instead of just one.
This will help keep the sound from passing through the walls, so that you can enjoy quiet time in your garage without having to worry about any outside noise leaking in.
Double drywall construction is not only a great way to get rid of unwanted noise, but it also reduces the chances of moisture damage, which can lead to mold and mildew growth.
Step-by-Step Instructions to Soundproof a Garage
You have read all these methods to soundproof a garage, but now you don’t know where to start and how everything should be done to be sure that you are doing everything right.
Here is the step-by-step process to soundproof your garage with the insulation and drywall construction.
Step 1: Remove all the Items from the Walls.
The first step to soundproofing your garage is to remove everything from the walls. This includes shelves, cabinets, and any other items that could potentially be nailed or screwed into the structure of the ceiling or walls. It will also help you to see the studs and determine how best to cover them.
Once you have removed all the items listed above, sand down any rough spots on the surface of the wall with an orbital sander or sandpaper. This will ensure that the insulation fits in properly and won’t cause problems later on.
Step 2: Install the Studs on the Walls.
Gather the Supplies
The first thing you need to do is determine how many studs you need. To do this, measure the width of the wall and convert them into inches. The standard distance between studs is 16 inches, so divide the width of your wall (inches) by 16 and add 1.
Formula: (Width of Wall in Inches / Distance between studs in inches) + 1
For example: if your room is 10 feet wide, then it will be 120 in inches. 120 divided by 16 = 7.5, add 1 to it and it will be approximately 8. So you’ll need at least 8 wall studs for this wall.
Find the Studs
Finding the studs in your garage wall is an essential part of adding new studs. It helps you install the new studs on top of the previous without damaging the old wall.
You can use a stud finder to locate the studs in your garage walls. The best way to find the studs is to start at one corner of the wall and work your way across it, marking each spot with a pencil as you go along.
Attach the Stud
Before attaching the stud use the level to make sure the studs are straight and in line with one another.
Drill pilot holes into each of these marks. Once you have drilled a hole into the drywall, insert one end of your anchor into this hole. Then, drive drywall screws to attach the studs to the wall. Make sure that they are secure and don’t move around when you touch them.
Step 3: Fill the Stud Cavities with Insulation.
The next step is to fill the cavities of your studs with insulation. I recommend using fiberglass insulation for best results, but any type of insulation listed above would work.
Cut your insulation into smaller pieces so that it fits into these holes easily. You can use scissors or a knife for this step
Stuff your insulation into every nook and cranny of each stud cavity until all of them are filled up with spray foam or fiberglass insulation.
Step 4: Install Mass Loaded Vinyl.
This is the most crucial step if you want to block out outdoor noise. If you don’t cover the walls with mass loaded vinyl, then this procedure will only help in reducing echo/reverb inside the garage, but it won’t be effective for blocking out noise.
- Measure the area you want covered with mass loaded vinyl. You’ll need to account for any seams between sheets of material and any corner cuts as well. Make sure you have enough material if you’re covering an entire wall.
- Cut pieces of mass loaded vinyl that are slightly larger than the area where they will be installed. This will allow for slight movements during installation and give you room for error when cutting around doors, windows, etc.
- Use spray adhesive or double-sided tape to attach the MLV to your wall studs, starting at one corner and working your way across the room. You can also use staples or nails, but these methods are less effective than adhesives or tape as they don’t provide as much soundproofing and are more likely to fall off over time.
- The final step is to seal up any gaps with caulk or spray foam insulation so that no sound can get through those spots.
Step 5: Install the Resilient Channels.
For installation, the first thing you need to do is cut the Resilient Channels to fit in between your studs. You can use a hacksaw to do this, but it’s best to make sure you’re cutting them just right before you start sawing away at it. Measure twice and cut once.
You’re ready to attach your resilient channels. To do this, you’ll need a hammer and nails that are long enough to penetrate the studs.
Start by placing one end of the channel on top of a stud, flush with the top edge of it. Then use a level to check that both ends of your channel are lined up horizontally with each other. Hammer two nails into each side of the channel.
Step 6: Hang the Drywall.
This is the last step to soundproof your walls. Here’s how you do it:
Measure the Wall and Gather the Tools
Measure the wall, then measure your drywall. Make sure that you have a piece of drywall that is large enough to cover the area of your wall.
Take the measurements with you to the store so you can find the right size of drywall sheets.
Make sure that you have an electric screwdriver and drill bits for drilling holes in wood. You will also need some screws and nails to secure the drywall in place after it has been installed.
Drive the Screws into the Drywall Sheet
To hang the drywall, you need to drive screws into the drywall sheet. You can use a drill or a screwdriver. If you use a drill, be sure to use a Phillips head bit and not just any old bit.
Repeat the process with all Drywall Sheets
Repeat the process with all the sheets of drywall. Take your time and use a level to make sure you’re getting it right. If you mess up and have to take down some of your panels, don’t worry. It’s going to be fine.
Step 7: Paint the Drywall with Sound Absorbing Paint.
You can use any regular paint to apply on drywall but soundproof paint is made from a variety of materials that are designed to absorb sound. When you apply it to drywall, it will help to reduce noise by absorbing the sound waves.
- Clean the wall with a drywall brush and water to remove excess dust, then cover the floor with drop cloths.
- Apply a thin layer of primer to the wall using a paintbrush, then let it dry overnight (at least 3 hours).
- Paint the wall with two coats of sound-absorbing paint, letting each coat dry overnight (at least 3 hours) between applications.
Use Other Methods
Now you have completely soundproofed the wall that is one of the main causes of outdoor noise. I hope this step-by-step process helped make more sense than methods alone would have.
You can combine this method with others, such as hanging soundproof blankets on the walls or placing acoustic panels there. Or you can soundproof the door with weatherstripping and other materials.
How to Soundproof a Garage for Band Practice (Helpful Tips)
Decouple the room by adding resilient channels in the walls. This will absorb sound and prevent it from bouncing around the room. Add carpeting to your floor to help absorb sound and reduce echoes. Use acoustic panels on walls and ceilings to dampen the sound even more.
To soundproof the garage for band practice, you can follow all of the methods mentioned above. However, you should keep in mind these four main principles to maximize soundproofing.
Key Principles of Soundproofing
Add Mass: Adding mass means making the walls thicker or adding more mass to the floor. This is because sound travels through air, which is lighter than most other materials.
Damping: Damping is a way to reduce the amount of noise that’s created by vibrations. It works by softening or absorbing sound waves as they travel through the room.
Sound Absorption: Sound absorption is the process by which sound energy is converted into heat. It’s a great way to reduce sound levels in your space.
Decoupling: Decoupling is a simple way to soundproof a wall. Decoupling involves creating an air gap between the materials that can absorb sound.
Room Inside A Garage
The first three principles are easily covered using the methods mentioned, but how decoupling would be achieved? One method is to add resilient channels, which has already been discussed. Another method is to create a room inside a garage.
If you are soundproofing a garage for band or music practice then building a room inside the garage would be no-brainer. This is called an “acoustic barrier” and it’s just like it sounds, it blocks maximum sound from your musical instrument to go out.
Here are some ways to build one:
- Hang up some drywall to dampen the sound around where you practice the music. It’s a temporary solution and will not cost much money.
- You can add flex walls on either two or three sides of your musical instrument (where you play). This is not something that you can do on your own.
Add Carpet to the Floor
Carpet is a great way to soundproof a garage because it absorbs sound much better than hard or smooth surfaces. Carpet also gives your band practice space a cozy feel, and makes it easier for you to hear each other when you’re playing music together.
Carpeting will help absorb some of the sounds that are produced by drums, guitars, and vocals. It also helps keep the sound in so that it doesn’t leak into other parts of your home or outside the garage.
This is an easy DIY project that can be done in a day by just one person. The only tools you’ll need are a tape measure and a screwdriver if you’re installing new carpet over an existing floor.
Tip for Soundproofing a Garage Workshop
Install vibration isolation blocks under machinery to reduce the vibrations that travel through the floor and walls. Place rubber beneath machines to reduce noise from impact. Use ear plugs when operating loud machinery or tools like table saws or grinders, to prevent damaging your hearing.
Garage workshops can be a great place to create and tinker, but the noise can be a problem for your neighbors, and your ears. Luckily, there are some simple tips to improve the soundproofing in your garage workshop.
Install Vibration Isolation Blocks
Vibration isolation blocks are basically what they sound like: blocks that are designed to isolate vibrations from reaching the floor. They’re super easy to install, too, you just put them under any piece of equipment that’s making noise such as any vibration tool or machinery.
Place Rubber Beneath Machines
You can soundproof your garage workshop by placing rubber beneath machines. This will reduce the noise and vibration that comes from the machines moving around on hard concrete.
Rubber is an excellent sound absorber, so placing rubber beneath the machines you use in your workshop will help keep those noises from escaping into the rest of your home.
Use Ear Plugs
If you’re working in your garage, you might be surprised to learn that the sound of your hammering and sawing can actually be quite loud. In fact, industrial noise levels can reach over 100 decibels, that’s louder than a lawn mower or car horn.
If you want to keep from damaging your ears and still enjoy this hobby, it is recommended to wear earplugs. Not only will this protect your hearing from damage, but it can also make it easier for you to focus on the task at hand and stay safe. You can find these at any drugstore or hardware store, and they come in a variety of styles and colors.
Earplugs are easy to use: just insert them into your ear canal and they’ll effectively block out the sounds around you so that all you hear is muffled noise.
Using Green Glue to Soundproof a Garage
Green Glue is a soundproofing material that is used to dampen noise and vibration between two surfaces. It is a viscoelastic compound that converts sound energy into heat energy, thereby reducing noise levels. Green Glue is available in tubes or buckets and is applied between two layers of building material, such as drywall, to create a sound barrier.
How does Green Glue work?
Green Glue works by converting sound energy into heat energy. When sound waves travel through a surface, such as drywall, they create vibrations. These vibrations then travel to the other side of the surface, creating noise. Green Glue is applied between two layers of drywall, for example, and works by damping these vibrations. This is achieved by the material’s viscoelastic properties, which allow it to deform and absorb sound energy. As the vibrations travel through the Green Glue layer, they are converted into heat energy, which dissipates into the surrounding air.
Steps to soundproof a garage with Green Glue
To soundproof a garage using Green Glue, follow these steps:
- Assess the existing structure of the garage and determine the best method of soundproofing. This may include adding insulation or sound-absorbing panels, in addition to using Green Glue.
- Purchase the required materials, including Green Glue, drywall, screws, and sealant.
- Install the first layer of drywall on the garage walls or ceiling, depending on the area to be soundproofed.
- Apply a liberal amount of Green Glue to the back of the second layer of drywall, using a caulking gun or similar tool.
- Press the second layer of drywall onto the first layer, ensuring that it is firmly in place.
- Screw the second layer of drywall into the wall studs or ceiling joists, using screws long enough to penetrate both layers of drywall and the stud or joist.
- Apply sealant around the edges of the drywall to ensure a tight seal.
- Repeat steps 3-7 for any additional areas of the garage that require soundproofing.
Conclusion (Soundproof A Garage)
Isolate the soundproofing material from the floor by using wood or rubber pads, and make sure the garage door is well-sealed to minimize noise. Add acoustic ceiling tiles that are designed for use in garages, which will help to absorb some of the sound coming off the floor and walls.
Your garage could be your castle, the focal point of your home, but this will not happen if there are noises that interfere with the peace and quiet you want.
There are several ways to soundproof a garage door. Some will be easier to use than others, but the most important thing is to keep it safe and secure.
So, now that you know all about soundproofing your garage, it’s time to get started! If you follow these steps and take the time to do a little research on the best products for each step, you’ll be well on your way to reducing noise from your garage.
Frequently Asked Questions (Soundproof a Garage)
How can I soundproof my garage cheaply?
One of the best ways to cheaply soundproof a garage is to use a combination of materials, including drywall, insulation and mass loaded vinyl sheets. The drywall and the mass loaded vinyl sheets will help you block out the sound, while the insulation will help you absorb the sound.
Can you completely soundproof a garage?
You can make a garage quieter, but you can’t completely soundproof it. Soundproofing is all about trapping air in the walls, floor and ceiling of the room to inhibit sound from traveling. For the best soundproofing, choose materials that add mass, absorb sound, or dampen vibrations.
If you want to get the best soundproofing results, then it’s important that all three areas are addressed.
For example, while drywall works well as a surface material for walls and ceilings, it doesn’t provide much insulation.
So if you add drywall on top of existing drywall without adding an additional layer of insulation between them, then your efforts aren’t going to be very effective at blocking out noise from outside sources.
How expensive is it to soundproof a garage?
It depends on the size of your garage and how much soundproofing you want to do. The average cost of soundproofing a garage is around $1,000. It can be done for less, but you may have to settle for less-effective solutions that won’t be as effective at blocking noise.
However, if you’re looking to make your garage as quiet as possible and ensure that no sound gets through at all, then it’s going to be much more expensive ($300 – $5000). You’ll have to pay for higher-end materials and/or hire professionals who can do the job right.
What’s the cheapest way to soundproof?
Acoustic panels and soundproof blankets are the cheapest ways to block outside noise. They can be used to cover up existing surfaces that are exposed to outside noise, like walls and windows. These products are also great for creating a new room within your home or office space.
Acoustic panels are great for blocking out sounds from outside and inside the room. They can help you get rid of the noise from traffic, construction or even loud neighbors.
Soundproof blankets are another great way to block out noise from outside and inside a room.
These blankets are made from different materials like glass wool and foam rubber, which makes them good at absorbing sound waves coming from all directions in a room.
