Soundproofing a doorway may seem like a very hard task for many people. However, it’s actually one of the easiest and cheapest soundproof projects you will ever do.
After moving into my new house with my wife and kids, I had trouble sleeping and working in peace. It wasn’t because my kids were always playing, but because of a hollow front door.
What most people do not realize is that most doors in homes today are hollow and there are all kinds of way in which sound can get through. It shouldn’t be any surprise because most interior doors have gaps around the frame and at the bottom near the floor, where noise can travel into your room very easily.
Rather than ignoring the disturbing noise, the doorway should be one of the first places to start a soundproofing project.
If you are looking for how to soundproof a doorway, luckily you’re in the right place. In this article, I will explain to you several ways to soundproof a doorway without breaking your wallet. Some of these steps may need a few tools to get the job done, while some steps are easy and quick to install.
Each of these steps can be done on their own, however, we recommend combining as many of them as possible for a more effective result. Without further ado, let’s take a look at the methods below and you can take the time out and decide on what works best for you.
How to Soundproof a Doorway
1. Seal All Gaps and Holes
The first thing I suggest doing is seal all the gaps and holes on the edge of the door. Holes and gaps on the door are one of the main culprits for airborne noises passing through the doorway.
If you should inspect your doors properly you’ll notice that most doors have cracks and gaps and when looking to soundproof the doorway, you should try your best to seal these first.
If the gaps and cracks around your door aren’t big, it may be a bit difficult to find them. A great idea would be to turn off all the lights and then ask someone to hold a light behind the door. The gaps and cracks will allow some of the light to get through.
Once you have located all the gaps and cracks, it’s now time to seal them. I recommend using this high-quality insulating sealant. It is considered to be one of the best sealants on the market. It’s a water-resistant airtight and paintable sealant that is the right fit for gaps that are 1 inch or greater.
If the gaps on your door are bigger, then this may not work for you. However, for smaller gaps, I suggest using Red Devil Small Gaps Foam. Once you finish, you’ll notice a huge difference.
2. Apply Weatherstripping Tape
Applying weatherstripping tape to your door is another affordable way to get rid of unwanted noise. Weatherstripping is usually made from sound absorbing materials such as fiberglass.
Also one of the main benefits of using weatherstripping is that it’s quite easy to apply and can be easily removed as well. Although its main purpose is to keep out rain, dust and wind from getting inside, it’s a good sound absorber.
If you are interested you can try this self adhesive weatherstripping tape and securely apply it all along the door frame to create compression and an airtight seal to prevent noise passing through the door.
3. Install a Door Sweep
When it comes to small cracks around the edge of the door weatherstripping takes good care of that, but it doesn’t deal with the biggest crack which is located at the bottom of your door.
If you look closely you’ll see a gap between the floor and the bottom of the door. Because of its size, it is able to let in lots of noise and this is why installing door sweep is very important to soundproof your doorway.
A door sweep main function is to help seal the gap between the door and floor whenever the door is closed. If you are serious about soundproofing your doorway, then I recommend checking this one out on Amazon. If you decide to buy this product, you should also keep in mind that door sweep isn’t easy to install as the Weatherstripping tape.
4. Install a Door Gasket
If you don’t have a problem spending, you can try to get yourself a door gasket instead of a weatherstripping tape. They both work just the same, they are used to seal gaps at the jambs and the header of the door. By using a door gasket, you will certainly get tighter than you can get with weatherstripping tape.
5. Use a Soundproof Blanket
Another effective and cheap way to soundproof your hollow door is to use soundproof blankets. These blankets are usually made of fiberglass, a material that is known to be a good sound absorber. Because of the fiberglass panel, this heavy blanket will soak up a lot of sounds.
The installation process should be quite easy, all you have to do is hang them onto hooks at the back of the door. I suggest using these heavy duty hooks with anchors (link to Amazon). Because of this, you will have the ability to easily put them up or bring them down when you want to.
The only downside with soundproof blankets is that it may not fit your design aesthetic perfectly. These blankets are usually not visually attractive. So because of this I highly recommend that you use them for rooms that you don’t care as much about how they look, like the bathroom.
6. Add Soundproofing Foam Panels
If you are on a tight budget and don’t want to spend the money to get a soundproof blanket, you can certainly use a more affordable option which is a soundproof foam panel.
These acoustic foam panels will do a great job of dampening sound especially echoes. If you have an indoor studio on the other side of the doorway, then installing these acoustic foam panels would be a great idea.
You can purchase 12 pack acoustic panels for a very reasonable price over here on Amazon. You can also use a few of them towards your studio because soundproofing your doorway won’t take all of them. One thing I really like about these is that you have multiple colors to choose from and each panel is 1 square foot and has a thickness of 1 inch.
You can easily attach these panels using a command strip. These are extremely easy to use and they won’t cause any damage to the door.
If you don’t want to use foam panels, then you can try installing acoustic panels on the back of the door instead. Both of them are very effective, only thing is that acoustic panels are slightly better.
7. Place a Rug
This is a simple step that won’t take much of your time. You can simply purchase some rug for a cheap price and place them near your doorway. Rugs can be very effective in eliminating echoes as well and it is also a great idea to place a rug in your hallway or basement where there are lots of echoes.
Using rugs will not only reduce sound and echo but also enhance the visual appeal of the room. The only disadvantage is that rugs are pretty expensive and although they help to reduce sound, they are far less effective compared to other affordable soundproofing methods.
Even though weatherstripping and door sweep were amazing, I still decided to get myself a couple of fluffy rugs. If you are looking to reduce the overall noise level, I suggest you try out the Safavieh Hudson Shag Collection. It’s an extremely thick rug that is made from polypropylene fibers that makes it strong and durable. Another benefit is that you also get to choose from a variety of colors and designs as well.
8. Add a Layer of Soundproof Paint
You can check some of your local stores to see if any of these interior paint is in stock. If you are able to find it in a color that matches your door or the decor of your room, then you can consider giving it a try.
Soundproof paints are great at eliminating medium pitch noise such as conversation, singing, television, etc. But, it’s not effective at stopping high noises. With that being said, it’s still cheap and makes a great alternative.
9. Get Some Soundproofing Curtains
We all know that curtains or drapes are made for use on windows. But did you know that curtains can also be used on doors?
Yes, you can certainly use curtains for your doors because they are a great sound absorber and they are excellent for dampening the sound. Also, there is no reason why you can’t install some on your door.
In order to place soundproof curtains on your door, you will need to install a curtain rod up above your door frame. If your not a handy person, this may take some time but it is not difficult to do. Once you finish installing the rods, you can then use the drapes just like you would on a window.
Using heavy curtain like these ones on Amazon, will also block out any light and can even trap heat because of their insulation. When choosing a soundproof curtain, you will have the ability to choose any colors and designs that match your room decor.

10. Dampen the Noise on the Other Side
A doorway is just a channel for sound. It is not the source of the noise. When soundproofing a doorway reducing the sound on the other side is very important.
To do this you may decide to use rugs as we mentioned earlier in the post. Using a rug won’t directly eliminate the sound altogether, but it can help dampen it a little. Another impressive way to dampen sound near a doorway is to add bookshelves and canvas painting on either side of the doorway.
We suggest that you first identify the main cause of the noise and try your best to dampen the sound as much as possible.
11. Use Mass Loaded Vinyl
Mass loaded vinyl is a type of thick material that acts as a good barrier for airborne noise. If you are annoyed by the noise from the hallway while you’re in your home threater, then the best idea would be to install mass loaded vinyl to reduce the noise.
Installing mass loaded vinyl is very easy. All you will need to do purchase this affordable TMS Mass Loaded Vinyl on Amazon.
After purchasing you will have to cut it according to the size of your door. You will then have to attach it to your door with some heavy adhesive. If you are not satisfied and want to reduce more noise, then it would be best if you double the layer and attach them to your door after.
The only downside of using mass loaded vinyl is that it is a bit expensive. You can find some cheap one on the market, however, using these won’t be effective and will be a waste of money. So if you are considering spending money to soundproof your doorway, then it would be best if you invest in the right material. You can check these ones out on Amazon if you are interested.
12. Buy a New Solid Core Door
If you are serious about soundproofing your doorway, then investing in a solid core door should do the trick. A solid core door with more mass will dampen any sounds that pass through them instead of amplifying it like a hollow core door.
Most interior doors in the house are hollow core doors which is usually lightweight, thin and a great amplifier of sound. This is why I highly recommend buying a new solid door.
If you’re not a handyman, then installing the door should be quite difficult. If you are not sure about the installation process, it may be a great idea to call in a professional to get the job done.
If you don’t want to invest this much in a new door, you can try adding some mass to your existing hollow door instead. You can do this by attaching pieces of wood in the same size as your door.
Alternatively, you can purchase some drywall, then measure the size of your door. Once you have gotten the measurements correctly you can proceed to cut the drywall according to the measurements, then attach the drywall using adhesives material. By doing this you will significantly reduce the amount of sound that goes through your door.
I hope this guide is everything you need to soundproof your door. You may also notice that soundproofing your door is quite the same as soundproofing any other area of your house, it can be extremely cheap or expensive.
If you are looking to reduce the noise in your house to an acceptable level, then I suggest combining these methods together for more effective results. You can start by trying out the more cheaper and easier solution first to see how much it helps, then try another option. If you tried all these methods and none worked, you can also replace the door entirely.
