Whether you’re a light sleeper, have a newborn or work a night shift, soundproofing your door can help everyone in your household rest better and longer. Although professionals can add insulation or drywall to make your room quieter, there are simple and cost-effective DIY methods to soundproof your door.
Sound travels through air quite easily because it is not very dense. Doors are large openings, and sound waves travel through them easily. Even a closed door may not be enough to reduce outside noise. If your room is particularly noisy, the problem may be the door’s construction or gaps around the door that allow noise to enter even when the door is closed. Fortunately, there are many affordable ways to make your door more effective in stopping unwanted sounds. Depending on how quiet you want things to be, you may need to use a combination of soundproofing techniques.
1. Use soundproof paint.

Sound-deadening paint, also known as soundproof paint, can quickly and easily block sound, but it has some limitations. The paint contains ceramic spheres that create an absorptive, rough surface that helps prevent sound from echoing, but it dries with a slightly raised surface instead of remaining perfectly smooth. This texture is not a problem if you only use it on a door, but you probably do not want to paint an entire room with it.
This special paint effectively blocks mid-range frequencies, such as human speech, making it an excellent solution if you want to have more private conversations. However, it does not block high or low frequencies, so traffic noise and high-pitched instruments will still be audible through the paint.
2. Install weatherstripping.

Even if your door is solid and well-built, there is usually a small air gap between the door and the frame when the door is closed. This gap can let in a surprising amount of noise. One of the simplest and cheapest ways to solve this problem is to install weatherstripping. Weatherstripping not only blocks noise but also prevents drafts around both interior and exterior doors.
Installing adhesive weatherstripping is very easy. Peel off the adhesive paper, stick the weatherstripping to the door frame, and cut it to the proper length. This seals any gaps around the door and helps block unwanted noise. Weatherstripping is available in different thicknesses, so you can seal gaps without making the door too difficult to open and close.
If you want to take your soundproofing to the next level, consider buying a soundproofing door seal kit. These kits use rubber gaskets instead of weatherstripping to create a tight seal. They are more expensive than weatherstripping, but they also block much more sound. They are more challenging to install, but the kit comes with complete instructions.
3. Install a Door Sweep

While weatherstripping is effective around a door, a door sweep is the best way to seal the bottom of the door. It consists of a rubber blade, a fabric bumper, or a series of bristles that sweep against the floor as the door opens and closes. Mounted to the bottom of the door with adhesive or screws, it blocks air and noise from coming in under the door, providing a complete seal when it contacts the door threshold. Door sweeps are typically installed on exterior doors but can also work well on interior doors.
Tip
If you have carpet, an automatic door sweep is recommended to prevent wear and tear. These devices are designed to lift up automatically when you open and close the door, sliding back into place when the door is closed for noise reduction.
4. Hang Soundproof Curtains

If you’re a renter and not allowed to install permanent soundproofing devices, soundproof curtains are an excellent solution. Although not always the most attractive option, they can provide good sound reduction without any permanent changes to the door. To ensure optimal soundproofing, hang the curtains in a way that eliminates any gaps around or between them and the door. You can use Velcro to attach them to the door frame or install a curtain rod above the door and hang the curtains from grommets or clips.
5. Use Acoustic Panels

Foam acoustic panels are designed to reduce noise in home theaters, recording studios, and other spaces. They can be attached to a door with glue, tape, or nails and are just as effective as they are on walls. However, acoustic panels are better at keeping sounds in the room than they are at keeping noise out. If you’re dealing with a noisy neighbor, they may not be the best solution. To improve effectiveness, choose dimpled, ribbed, or double-sided panels. Note that foam acoustic panels are flammable and produce a large amount of smoke when ignited, so they may not be suitable for use in living spaces, particularly in children’s bedrooms.
6. Installing a Solid-Core Door

Interior doors are often made of hollow-core to save on weight and cost. These doors have a wooden or foam frame for support, but the rest of the interior is hollow. Solid-core doors, on the other hand, are made entirely of solid wood and provide better insulation and noise reduction. While solid-core doors can be expensive, they are worth the investment for exterior doors. The cost of a hollow-core interior door ranges from $30 to $240, while a solid-core interior door ranges from $60 to $330. Replacing your current door with a solid-core door is the easiest and most effective way to block out noise and have a durable door that lasts for years.
If you want a more solid door but cannot afford a solid wood door, you may want to consider an insulated steel door. These doors are filled with insulating foam, offer similar sound protection and are less expensive.
7. Soundproofing the Adjacent Room

Soundproofing the room next to your bedroom can be helpful in reducing noise. If your bedroom door opens to a tiled living room, try making that room quieter. Hard surfaces reflect sound, while soft surfaces absorb it. Adding an area rug, plush furniture, curtains, and other sound-absorbing materials can make the space quieter. The less noise bouncing around the room, the less noise will creep in through your door.
FAQ
1. What materials can I use to soundproof a door?
To soundproof a door, you can use various materials that help reduce noise transmission. One option is to install weatherstripping around the door frame to seal any gaps. This will prevent sound from traveling through small openings. Another option is to use acoustic panels or foam panels, which can be attached to the door to absorb sound waves. You can also consider using a heavy curtain or quilted blanket as a temporary soundproofing solution. Additionally, adding a door sweep at the bottom of the door can help block noise from entering or leaving the room.
2. How can I reinforce the door to reduce noise?
If you want to reinforce your door to reduce noise, there are a few methods you can try. First, consider adding mass to the door by attaching a layer of mass-loaded vinyl or soundproof drywall. This will help block sound from passing through the door. You can also install a door seal kit, which includes a door sweep, door gasket, and threshold seal. These components will create a tighter seal and prevent sound leakage. Additionally, reinforcing the door frame with acoustic caulk or foam tape can further minimize noise transmission.
3. Are there any affordable DIY methods to soundproof a door?
Absolutely! There are several affordable DIY methods to soundproof a door. One option is to use a draft stopper or door snake, which can be placed at the bottom of the door to block sound from entering or exiting. Another affordable solution is to hang a thick rug or carpet on the back of the door, as this can help absorb sound. Additionally, you can create a homemade soundproofing barrier by filling a wooden frame with sound-absorbing materials such as fiberglass insulation or acoustic foam. This can be attached to the door using adhesive strips or brackets.
