Soundproofing Costs

Soundproofing projects may include soundproofing an entire room or just certain places in the house where you need to keep noise out. The most important cost factors are the size of the area and degree of soundproofing you require. Material and installation costs depend on the part of the room as follows:

  • Windows
  • Walls
  • Ceiling
  • Doors
  • Floors

Soundproof Windows Cost

The cost of soundproofing windows ranges from $300 to $1,500 per window. Additional features like sound deadening curtains or inserts may be enough to reduce noise if it’s only a minor problem. However, more severe cases require you to replace your existing windows with soundproof windows.

Soundproofing Walls Cost

Textured Wall Panels$1.60 - $4.60 per square foot
Hangings and CurtainsUp to $100
Foam Insulation$1.40 - $3.00 per square foot
Acoustic Tile$5 per 4’ square
Acoustic Foam$10 - $100, depending on size

Soundproofing an existing wall generally consists of installing additional wall coverings and materials to help absorb sound inside the room or within the wall.

Soundproof Drywall Cost

Soundproof drywall costs about $40 per sheet. QuietRock drywall reduces noise levels without sacrificing floor space by using patented thin wall technologies. It often outperforms gypsum walls composed of multiple layers and is more reliable than resilient channels. Some homeowners create the same effect with common drywall by increasing the layers (such as two or three sheets thick).

Soundproofing Ceiling Cost

Textured Paint$230 - $280
Acoustic Tile$10 per 20 inch square
Acoustic Foam$10 - $100, depending on size

Many of the options for soundproofing ceilings are similar to those for walls.

Soundproof Door Cost

A blanket made from sound-absorbing materials with a dense inner layer costs $300 to $455, which is effective for doors and other hard surfaces that reflect sound. Heavy curtains can also block noise that leaks through doors for $15 to $100 per panel. Foam insulation tape around the door and a plastic door sweep under the door can prevent noise from coming in through air gaps.

Sliding Glass Doors

The cost of soundproof sliding glass doors is between $1,300 and $4,000. They’re typically composed of laminated glass, which can reduce noise levels by more than 75 percent. These doors are also more difficult to break and have greater insulation.

Soundproof Flooring Cost

Carpeting is the most common soundproofing measure for the floor, which can cost over $1,000 per room. Mass-loaded vinyl reduces sound by adding mass to the floor, which costs between $100 and $200 for a 40-square-foot roll. Acoustic foam is a versatile material that you can use on a variety of surfaces, including floors. Some DIYers fill the subfloor with cheaper roofing shingles, which adds mass to the floor and deadens sound.

Cost of Soundproofing One Room

The typical cost of soundproofing a room ranges from $380 to $590. These figures include $170 to $250 for new materials, $190 to $300 for labor and $20 to $40 for tools. However, they don’t include the cost of removing existing materials or modifying existing structures.

The most important cost variables are the quality of the materials, size of the room and complexity of the project. You’ll typically buy materials by the length or piece. For example, foam insulation and linoleum are available by the roll, which contain a certain number of square feet of material. On the other hand, you’ll typically buy acoustic foam and tile by the individual piece.

If you hire a soundproofing contractor in your area to do the work, the company’s reputation, location and time of year may also affect the labor cost. Contractors generally charge by the hour, but the contract will usually specify a minimum number of hours they’ll need to complete the project.

Specific rooms that you may need to soundproof include a bedroom and your garage.

Cost to Soundproof a Bedroom

Soundproof drywall typically costs about $360 for a 10’ x 10’ room, which is about three times the cost of ordinary drywall. Bedrooms have a greater need for soundproofing since you spend a significant portion of your time in them sleeping.

Soundproof drywall is one of the most important considerations for reducing noise in a bedroom. Even if you’re on a tight budget, this type of room is the one place where you should consider using this relatively expensive material.

Cost to Soundproof a Garage

The cost of insulating all three walls in a one-car garage starts at about $640. A house already has insulation, which also blocks noise to some extent. However, garages rarely contain insulation, since this is usually an unnecessary expense for them. To soundproof the garage door, use mass-loaded vinyl (MLV), acoustic panels, or even sound-deadening blankets. For a more permanent solution, replace your garage door with an insulated door. Doors cost from $300 to $5,000, plus installation. Because of the dangers involved in replacing a door, consult with a garage door pro.

Cost to Soundproof a House

The total cost of soundproofing an existing house ranges from $10 to $30 per square foot. The most significant material costs include mass-loaded vinyl for the floor and acoustic panels for the other surfaces. You also have additional options for soundproofing if you haven’t built the house yet, including a second layer of drywall, resilient channels and additional studs to support insulation inside the walls.

Cost to Soundproof a Condo

Blown, or loose fill, insulation contains low-density cellulose that can help suppress noise for a cost between $1 and $3 per square foot. Residences like condos share walls with other units, making this type of soundproofing essential in these cases. Insulation is particularly important in a case where a neighbor has a TV mounted to the other side of a wall for your bedroom. It’s important to add insulation to the attic, which in many condos is a shared space that can transmit noise.

DIY Soundproofing vs. Hire a Pro

A project to soundproof a room with a material cost of at least $1,600 will probably have a labor cost of at least $300 if you hire a pro. The most important factor that determines whether you should hire a pro or complete a soundproofing project yourself is the level of soundproofing you need.

You can probably perform simple treatments yourself such as putting up tile and laying down carpet or vinyl flooring. However, you should hire a pro for work inside the walls such as spraying insulating foam, replacing windows and installing drywall.


What materials do you need to soundproof a room?

Textured wall panels are some of the most common materials to use in soundproofing a room. Replacing standard windows with those that have multiple panes is also an effective solution for blocking noise that originates from outside the house.

Why would you soundproof a room?

The most common reason for soundproofing a room is to prevent you from hearing neighbors with whom you share a wall. You’re also likely to want soundproofing if you live with a practicing musician, especially a drummer.

What are the advantages and disadvantages of a soundproofed room?

The biggest advantage of a soundproofed room is the peace and quiet it offers the residents, especially when they sleep at different times. The biggest disadvantage is the cost, particularly if you want to soundproof the entire house.

How much soundproofing foam do I need?

Six inches is a common thickness for soundproofing foam. This material primarily reduces echoes from sound after it enters the room.

How do you soundproof an existing wall?

Acoustic foam tile is one of the easiest ways to soundproof an existing wall. Other options include textured paint or thick curtains and other wall coverings.

How do you soundproof a room?

The methods of soundproofing a room generally consist of adding mass to reduce vibrations and adding surfaces to absorb sound waves. Adding mass is more useful for minimizing low frequencies, while adding surfaces is more effective for blocking high frequencies.

Can I reduce the noise from my ventilation system?

This is something people do when they soundproof a room for recording (such as a sound booth). Contractors install “dead vents” or “sound mufflers” at the air supply and return registers. Make sure that your HVAC technician checks to see if there are building codes for this type of venting. You’ll also want to consult a sound engineer, as the dead vent’s location and configuration could affect the sound that is recorded.
