Soundproofing interior and exterior doors is a practical solution to minimize the intrusion of external noise and create a more tranquil living space. Getting more peace from your home's doors can be as simple as hanging a curtain or as complex as replacing the door itself.


Weatherstripping is a versatile and cost-effective method to seal gaps around doors, preventing the infiltration of sound and drafts.

Things You’ll Need

  • Weatherstripping tape (vinyl, foam, or rubber)
  • Scissors
  • Cleaning supplies (alcohol or mild detergent)

Step by Step

Clean the Surface

Ensure the door frame is clean and free from dust or debris.

Measure and Cut

Measure the dimensions of the door frame and cut the weatherstripping tape accordingly.

Apply Weatherstripping

Peel off the adhesive backing and carefully apply the weatherstripping along the door frame, creating a tight seal. Make sure the door frame is dry before applying the weatherstripping.

Door sweeps are installed at the bottom of the door to block sound and prevent drafts. They are particularly effective for sealing the gap between the door and the floor. Here's how to install them.

Things You’ll Need

  • Door sweep
  • Saw, utility knife or tin snips
  • Screwdriver or drill
  • Screws

Step by Step

Measure the Width

Measure the width of the door, and choose a door sweep that matches the size.

Trim if Necessary

If the door sweep is longer than the door width, trim it to fit using a saw, utility knife or tin snips.

Align and Install

Close the door and position the door sweep along the bottom, ensuring it fully seals the gap. Use a screwdriver or drill to attach the sweep securely to the door.

Acoustic Door Seals

Acoustic door seals are specialized products designed to enhance soundproofing by creating an airtight seal around the door perimeter. They are particularly effective for blocking both airborne and impact noise.

Things You’ll Need

  • Acoustic door seal kit
  • Screwdriver or drill
  • Screws

Step by Step

Clean the Door

Ensure the door surface is clean and dry.

Position the Seal

Attach the door seal along the door frame, aligning it to create a tight seal when the door is closed.

Secure in Place

Use the provided screws and a screwdriver or drill to secure the seal in place, ensuring a snug fit.

Heavy Curtains or Drapes

Heavy curtains or drapes can add a layer of insulation and absorb sound, making them an effective method for soundproofing doors. These layers of fabric can also be great for blocking out cold air in the winter and keeping the heat in. Here's how to install curtains for soundproofing:

Things You’ll Need

  • Heavy curtains or drapes
  • Curtain rod
  • Mounting hardware

Step by Step

Measure and Install Curtain Rod

Measure the width of the door and install a curtain rod above it using the appropriate mounting hardware.

Hang Curtains

Hang heavy curtains or drapes on the rod, ensuring they cover the entire door area when closed.

Adjust as Needed

Experiment with the thickness and material of the curtains to find the optimal soundproofing effect.

Sealing Holes and Gaps

Identifying and sealing any gaps or holes around the door frame is a fundamental step in soundproofing.

Things You’ll Need

  • Acoustic caulk or sealant
  • Putty knife

Step by Step

Inspect for Gaps

Carefully inspect the door frame for any visible gaps or holes.

Apply Acoustic Caulk

Using a putty knife, apply acoustic caulk or sealant to fill in the gaps and create a seamless seal around the door.

Upgrade to Solid-Core Doors

Solid-core doors are thicker and denser than standard hollow-core doors, providing better sound insulation. While this method involves replacing the existing door, it can significantly enhance soundproofing.

Things You’ll Need

  • Solid-core door
  • Screwdriver or drill
  • Hinges (if incompatible with existing ones)

Step by Step

Measure the Door Frame

Measure the dimensions of the existing door frame to ensure the new solid-core door fits properly.

Remove the Existing Door

Unscrew the hinges and carefully remove the old door.

Install the Solid-Core Door

Align the new solid-core door with the hinges and secure it in place using a screwdriver or drill. If necessary, replace the hinges with ones compatible with the new door.
