How to Soundproof a Door (Cheap DIY Step by Step Guide)

Have you ever wanted a room where you can disappear and let off some steam? Me too. Well, some people prefer to have private spaces where they play loud music, scream, or do something to alleviate stress.

A soundproofed room is ideal for all of these. You can go in there and do whatever you want without raising complaints from your neighbors.

In a room, the door is a significant source of sound leaks and could be the weakest link in soundproofing a room.

It might be because of the building material which lets sound pass through easily. Alternatively, it could be the gaps on the bottom or on the sides that let the sound out.

While it would be nice to install acoustically rated parts for a soundproof room, these are quite costly.

You like many others are looking for a cheaper yet practical way to create a quiet spot, without breaking the bank.

Well, I took the liberty to come up with a guide for all things you might want to know about soundproofing a door. Read on to find out more.

Doors that can be soundproofed

You might be wondering, why to go through the trouble of soundproofing a door when you can just soundproof the room.

As I said, doors are a huge weak point in keeping the sound contained. With the wrong type of door, efforts of soundproofing a room will be meaningless.

The sound will just escape through the gaps and air spaces. Ideally, any door not dense enough to block sound can be soundproofed.

Door soundproofing works on the principle that sound travels well through air gaps and less dense materials.

Once you seal these sound leaks and make the door thicker, you should be able to transmit or receive minimal sound disturbances.

Here Are Some Easy Steps to Soundproof a Door:

1.  Making door Replacement.

The first obvious choice would be swapping out your door for a denser one. It might not be an acoustically rated door, but it should be thick enough to maintain a reasonably quiet environment.

This step is ideal for you if you do not want to go through the hassle of altering the door yourself. If you do not have the option of modifying your door or paying for someone to do it, buying a solid core door is a great alternative.

Unlike the regular hollow doors, these have a densely packed center that blocks noise more efficiently. They are quite thick for effective noise blocking. Because you’re only going to swap out the old door for the new one, installation is quite easy.

2. Applying Seals

If you do not want to go through the trouble of replacing your entire door, you could apply seals to minimize air leaks on your door.

Whether you choose draught excluding style seals or professional acoustic seals, these will help you reduce sound transfer.

The acoustic seals are more expensive than the regular seals and might need a larger budget than the regular seals. Installation is quite simple and straightforward.

However, you can use a soundproof door weatherstripping kit to cover off the gaps, what I like about these weatherstrips is not only they help sound dampen your door but they are pretty cheap and effective too ( Click Here to See the Current Price on Amazon).

Door gaskets and bottom extensions

These serve additional seals for the sides and bottom of the door. Gaskets, for example, ensure that the space between the door and frame on the sides and top are covered.

We recommend that you find high-quality weatherstrippings that will fit your door. These gaskets are usually made from materials that ensure your door is sealed but remain flexible and effective even as time passes.

The gaskets can be made from a variety of materials ranging from adhesive foams to rubber seal. You might want to make a choice that blends properly with your door finish.

The door bottom is applied to seal the bottom space that is a significant sound outlet on your door. Finding an automatic bottom that will seal the space when the door closes and remove it when it opens is a smart choice.

These not only block noise but also prevent unwanted light and draught from coming in.

3. Modifying your door

This is the handiest work-intensive way of soundproofing your door. It involves taking apart your doors and putting it back together in a way that ensures to block sounds or noises.

This modification is for transforming hollow doors into more dense doors for minimal sound transmission. Let’s take a look at simple ways you can soundproof your hollow door.

Basically, you need to fill up the hollow space inside the door. The first step is to take down your door and separate the exterior from the internal sections. It might be difficult at first but with the help of several tutorials and reliable power tools to do the separations.

The next step will be installing soundproof material such as rubber or mass coated vinyl for soundproofing purposes. Once the material is fitted, you can return the door to its original position.

Types of soundproofing material

There are many soundproofing materials available because of the many soundproofing requirements around a space depending on where the room is and many other factors. Here are some main items you will need in the general soundproofing of your door.

1. Acoustic Foam

Rather than reflect noise, these absorb it and soften echos. Foams help improve the sound in a room. Acoustic foam, for example, is exclusively designed for this role.

You can stuff this inside your hollow doors to control noise and mitigate sound emissions. Other materials such as panels and seals are useful in ensuring you have a proper soundproofed door.

Given the range present in noise and sound accumulation, your most significant task maybe incorporating the suitable soundproofing technique or method.

It means that you have to take into consideration all your door needs and combine that with all your life hacks.

Do not choose an installation method just because. Ensure you fully understand the extent of its practicalness and functionality.

2. Soundproof Door Weatherstripping Kit

Weatherstrips are great because they can help close off the gaps between the door and the frame, they are straight-forward and easy to install so you don’t have to hire a soundproofing expert to do it for you.

3. Mass loaded vinyl

This thick material is an excellent barrier against air transmitted sounds. It is not only effective against noise but is easy to use and install.

Heavy adhesives or a stapler can attach it. For the best result, you might want to attach multiple layers of MLV.

4. Noise Blocking Door Sweep

Door sweeps are like door bottoms. They share the working principle that if the gap between the door and floor is sealed, then no sound will leak out.

These, however, are not an easy install option. You might require the help of a trained professional to install them for maximum soundproof capabilities properly.

5. Soundproof Blanket

These are a great way to reinforce all the soundproofing work you’ve done. These are probably the easiest way to help to soundproof your door.

All you need to do is hang it on door hooks and TADA! Installation is complete.

What you need to know about insulation and soundproofing a door

Sound insulation prevents any transfer of sounds between rooms. There are several materials available in the market to help you insulate your door as a soundproofing method.

Depending on your proofing requirements, choose between varieties of items for the ideal insulator for your needs.

Fiberglass and mineral wool are great options for anyone looking to soundproof their door by insulation.
