How to Soundproof a Door

Acoustic Steel Door

When it comes to reducing unwanted noise, one of the most overlooked areas in any home or office is the door. Whether it’s street noise in Brighton, noisy neighbours in Hove, or sound travelling between rooms in Worthing, doors often allow significant amounts of airborne noise to pass through. The good news is that with professional help, soundproofing your doors can make a big difference. Creating a quieter, more peaceful space.

At West Sussex Soundproofing Ltd, we specialise in door soundproofing solutions. Across Brighton, Hove, Worthing and throughout Sussex, led by Daniel Pelser. Who brings over 20 years of hands-on experience in professional soundproofing design and installation.


🔊 Why Doors Let in Noise

Doors, especially hollow-core or lightweight internal ones, are often the weakest points in a soundproofing system. Gaps around the edges, under the door, and even the material of the door itself all allow sound to leak through.

Common noise problems include:

  • Airborne noise such as talking, TV sounds, or traffic.
  • Impact noise like doors slamming or vibrations transferring through frames and floors.

🛠 How to Soundproof a Door

Here are the main methods used by professionals like West Sussex Soundproofing Ltd:

  1. Replace Hollow-Core Doors with Solid-Core Options
    Solid-core doors are much denser and offer significantly better sound insulation. They reduce airborne noise and create a sturdier barrier between rooms.
  2. Add Acoustic Door Seals
    Soundproof seals and perimeter gaskets close off the small gaps between the door and frame. One of the biggest culprits for sound leaks.
  3. Install Drop Seals or Threshold Seals
    A drop-down acoustic seal fitted at the bottom of the door automatically lowers when the door closes, blocking sound that escapes under the door.
  4. Use Soundproofing Panels or Acoustic Blankets
    Adding acoustic panels or soundproofing blankets to the door surface can help reduce mid-to-high frequency noise. It is ideal for studios, offices, or home theatres.
  5. Reinforce Frames and Surrounds
    Soundproofing isn’t just about the door — it’s also about the frame and wall construction. Professional installers like Daniel Pelser ensure the surrounding areas are properly treated to prevent vibration transfer.
