How to Soundproof a Laundry Room

Vibration is the primary problem we hear about. When machines make contact with the floor or walls directly, they transfer structural vibration throughout the home. First, make sure the washer and dryer are level and not touching surrounding walls. Even light contact can transmit vibration.

We’ll give you three options for reducing that vibrational noise going into the floor, but for more machine-specific strategies, see how to soundproof a washing machine.

Option A: Use a Washing Machine Mat

Install a washing machine mat beneath the unit. The Stomp Mat isolates the machine from the floor, reducing impact energy transfer.

Option B: Install Isolation Pads

Place washing machine isolation pads under each machine foot. These reduce vibration at the contact point and are a simple, quick-install solution.

Option C: Upgrade the Floor Underlayment

If renovating or installing new flooring, use a tile flooring underlayment like UnderBlock beneath the finished surface. This reduces impact vibration and improves overall floor isolation.

Alternative for Dryers: Add Damping to the Drum

Stick on sound deadening material to the dryer drum housing. This reduces resonance and vibration of thin metal panels.

Hollow-core doors leak sound easily. Replacing it is your first step. If replacing the door is not an option, read this for alternatives to replacing a hollow core door. Assuming you can replace the door, get the Sound Lock™ Door Seal Kit to seal around the perimeter of your door.

If machines touch walls, vibration transfers directly into studs and framing. Always maintain clearance between machines and walls. To reduce sound transmission add a second layer of drywall with Green Glue between layers to soundproof an existing wall or construct new soundproof walls with mass loaded vinyl on the studs.

Sound inside a laundry room reflects off hard surfaces. This creates reverberation that increases perceived noise. Add acoustic treatment to reduce echo and lower the overall sound levels in your laundry room. Budget friendly materials like EcoVerb Roll and CelluZorbe help by absorbing reflected sound to improve the acoustic environment inside the room.
