How to Soundproof a Door – 10 Ways to Soundproof a Door

1. Use a Door Gasket

Door Gasket for Soundproofing door

Using or implementing a door gasket on your door will reduce sound or soundproof your place drastically. This requires a little bit of investment because you need to buy door gaskets. If you ask me for my recommendation on the best door gasket that I am using currently, then it would be this Metro Moulded Parts Front Door Seal. 

TRIM-LOK - X101HT-25 Trim-Lok D-Shaped Rubber Seal (Thick...
  • EPDM FOAM RUBBER SEAL: Trim-Lok D-Shaped Rubber Seal drowns out noise, eliminates vibration, and protects your vehicle, boat, or home from outside elements.
  • MANY APPLICATIONS: Durable Trim-Lok Foam Seals can be used for marine, automobile, and home cases – providing hatch, window, and door seals for cars, trucks, RVs, trailers, boats, and more!
  • WEATHER-RESIST: These rubber D-seals provide excellent resistance to water absorption, ozone, sunlight aging, low temperature, and compression set. General temperature rating of -20°F to +158°F. It is a reliable weatherstrip seal for many applications.
  • EASY INSTALLATION: Adhesive-backed D-shaped seals made with two options: BT (3M) tape is a high-strength automotive-grade tape, while HT tape is a general-purpose pressure sensitive tape. Both offer quick, easy, and efficient installation.
  • DIMENSIONS: This weather-stripping adhesive rubber seal measures .50” in height, .50” in width, and is 25’ in length. It is also available in a variety of edge thicknesses and can be cut to fit your specific application.

Door Gasket is very similar to weather-stripping tapes but more efficient with more applications. It’s an effective way for soundproofing a door. What a door gasket does is fills up all the gaps in the edges and sides of the door with this rubber gasket that stops the sound to pass through the gaps when the door is closed. Door gaskets also have multiple applications such as it blocks out Sound, Light, Moisture, Dust, and Dirt, and other pollutants to get inside the house or office.

2. Seal all the Gaps and Cracks

This method is very crucial and depends on the situation. You need to seal all the gaps and cracks. This is the first step that I would suggest for soundproofing a door. Sealing the gaps and cracks in the door or around the door is very affordable and effective to soundproof the door.

The cracks and gaps in the door are the main culprits that let all the sound or noise into the house or office, blocking them or sealing them will reduce the sound very much.

To identify the Gaps and Cracks in the door

  • Turn off all the lights and also close all the drapes or curtains.Now see if there are any light passing through the door, if there is light passing through it means that your door has Gaps or Cracks. Make sure you do this in the daytime when there is sunlight outside. Here are some good sound reducing curtains if you need any.
  • If there is no light outside then ask someone to go outside the door, close the door and ask them to use a torch or light. If you see light coming in from the gaps then you have a door with gaps and cracks.

Sealing the gaps and cracks in the door is very easy, all you need to do is buy this insulating sealantthat can be used to seal the gaps and cracks in the door. This insulating sealant is spray type sealant which airtight in nature. Just spray this insulant sealant on the gaps and cracks of the door to seal those gaps and cracks. Just let the sealant dry. If it doesn’t look good or doesn’t blend with color, just paint above it.

  • Foam & fill minimal expanding polyurethane sealant, 12 FL. Oz.
  • Highly durable
  • Use for Gaps & Cracks up to 1" in size
  • Seals, Bonds & Insulates

If the gaps or crack in the door are very small, let say smaller than 1 inch then the above-mentioned insulant sealant won’t work. You need a Foam sealant for gaps or cracks that are smaller than 1 inch. The Red Devil Foam Sealant is what we recommend to use. It’s very affordable to easy to use.

3. Use Soundproof Blankets

Soundproof Blanket on the Door is a sure shot and 100% working method for soundproofing a door. These soundproof blankets are made up of a material called fiberglass which is popularly known for its sound-absorbing capabilities. These fiberglass soundproof blanket are super effective to soundproof a door.

The installation of these soundproof blanket is very simple and easy. All you need to do is just hang them above the door with hooks that door this blanket on the door. That’s it, that’s how easy it is. One of the biggest demerits of these soundproof blankets is that these blanket are not visually very appealing and looks kinda ugly. I would recommend using these soundproof blankets on doors that are not every public for example like the laundry room door, which is quite noisy or uses these soundproof blankets on the Basement door.

4. Use Soundproof Rug

Using a soundproof rug is very similar to using a soundproof blanket, but these types of the rug will dampen the soundproof unlike where the soundproof blankets absorb the sound.

Rugs can be used as a soundproof blanket alternate because of their visual appeal. The soundproof rug can be very much good looking at the same time does it work which dampening the sound. But rugs are not so effective if the goal is to soundproof, unlike others. The heavier rugs are very soundproof because the heavier the rug the more sound or echo it could dampen and more soundproof effectiveness.

5. Use a Door Sweep

Door Sweep for Soundproof

Using or Installing Door Sweep on the door is a good idea for soundproof. The door sweep is not only working used or installed on the door for soundproofing, but it also has a lot of different benefits. You can block all the parts of the doors using Door Gasket, Weather-stripping tape, or any types of insulating sealing but you can’t block the biggest gap in the door which is the space between the door and the floor, that is where you implement the door sweep.

6. Use Weather-stripping Tape on the Door

After reading the title, I am sure you are a little bit shocked that you can use weather-stripping tape on the door to soundproof. Because even I was. But I read this article on Energy.gov on weather-stripping tape and learned that you can use weather-stripping tape on the door to soundproof.

Weatherstripping tape is used in the garage door for a long time now. But the fact that they can be used to soundproof the door is genius. Weather-stripping tape is made up of a material called fiberglass which is a sound-absorbing material in nature. If you are wondering about the installation of weather-stripping tape, don’t worry, these types of tapes come with an adhesive side which can be used to attach it to the door.

If you looking to buy a weather-stripping tape then this Weatherstripping Tape is the one that I recommend you to buy.

7. Use Soundproof or Sound-Absorbing Foam Panels

Another way for soundproofing your door is  sound-absorbing foam panels. If you think soundproof blankets or a sound-absorbing rug is expensive then, soundproof or sound-absorbing foam panel is the way to go. What these soundproof foam panels do is they are made of a material that is known to increase the air resistance on which the panels are placed, which in return reduces the amount of sound that passes through them.

The installation of these soundproof foam panels is super easy. Their procedure is exactly like the soundproof blankets that I have mentioned above. All you need do is just place the soundproof foam panels on the door and you are good to go. Now that you have placed you have soundproofed the door.

If you are interested in buying a good and quality soundproof foam panel then I recommend you to read this article on best acoustic foam paneland if you gonna hang this on the door then I don’t recommend you to nail them down as they would damage door instead buy this Command Picture Hanging Stripswhich will help you place these soundproof foam panel on the door.

8. Dampen The Noise On The Other Side

All the methods that I have mentioned before in the above methods are what to be done from the inner side of the door, the door when you enter but this method is to dampen or soundproof the door which is on the other side. This is a very important step to be considered if you wanted to achieve an absolutely soundproof home or office.

These are some of the stuff that we suggest you do if you want to dampen or soundproof the noise on the other side which is you can use soundproof rugs on the other side of the door. You can also try out Soundproof Blankets, Use Door Sweep, Weatherstripping Tape on the other part of the door, or you can also soundproof foam panels.

You can also ignore this part, but I really recommend you to follow this part for full effectiveness.

9. Use Mass Loaded Vinyl

If you are wondering what the hell is Mass Loaded Vinyl, then Mass Loaded Vinyl is a thick material or a thick agent that acts as a barrier or a wall to the sound that is been transmitted through the air.

Buy the Mass Loaded Vinyl, Cut the vinyl according to the size of the door and stick or attach it to the door. To stick or attach the mass loaded vinyl you can use adhesive or staples.

If you want the mass loaded vinyl to be very effective then you can buy two of those and attach one after the other in the door. By doing this it will act as a double barrier and protect the sound from entering it. One of the disadvantages of using mass loaded vinyl is that it is quite expensive but totally worth it.

10. Buy a Brand New Door

Even after doing all the above methods if your door is not soundproofed then you really need to get a brand new door. Because the old door starts to get pores and cracks that make the sound enter through the door. One solution is to buy a brand new door. One suggestion that I would give is to buy a solid door and not a hollow one. Hollow doors are very sound friendly whereas a solid door is very strong with the soundproof absorbant and soundproofing.

And one more suggestion is to get a professional person to attach the door in your place. Buying a brand new solid door will definitely soundproof your place for sure.
