How to Make a Washing Machine Quieter

Floor isolation is the most important first step because the spin cycle generates significant impact energy.

Option A: Washing Machine Anti Vibration Mat

A full-platform isolation solution like the washing machine anti vibration mat sits beneath the entire washer or washer/dryer footprint. The dense rubber construction of the Stomp Mat reduces impact energy before it transfers into the floor system.

After positioning the mat, carefully place the unit on top and re-level the feet. This approach works best when you feel vibration through the floor or hear rumbling in rooms below.

Option B: Washing Machine Anti Vibration Pads

Washing machine anti vibration pads isolate each machine foot individually. By breaking the direct contact point between the appliance and the floor, they reduce vibration transfer at the source.

Lift each corner of the unit, position one Super W pad beneath each foot, and re-check level and stability. Pads are ideal for moderate vibration issues or when you need a fast, low-profile installation.

Alternative Approach: Laundry Room Floor Underlayment

If you are installing new flooring, adding a rubber underlayment beneath the finished surface can reduce impact transmission across the entire laundry room. This is a structural solution that treats the whole floor assembly rather than just the machine contact points. It is most effective during renovation or new construction rather than as a retrofit.

Once the machines are isolated from the floor, the next step is reducing resonance and mechanical vibration within the units themselves.

Washer: Sound Deadening on the Metal Wall Panels

Applying a vibration dampening mat to the washer’s metal cabinet panels helps control panel vibration caused by the motor and spinning drum. Thin sheet metal can resonate like a drum head, amplifying noise. Adding constrained layer damping reduces that resonance and lowers overall sound output.

Always unplug the appliance and avoid covering ventilation openings or electrical components.

Dryer: Sound Deadening on the Dryer Drum

Dryers often produce metallic resonance from the outer drum housing. Applying Damplifier Pro™ Sound Deadening Mat to accessible exterior drum panels and cabinet walls reduces vibration and ringing during operation. Even partial coverage can significantly reduce panel resonance.

Decouple the Units

If the washer and dryer are installed side-by-side, they can knock and vibrate into each other and into nearby walls. Inserting OverKill™ Closed Cell Foam between the units and between the appliance and the wall helps interrupt that direct contact path. This is especially helpful when machines are tightly fitted in a closet or alcove.

If vibration has been reduced but sound is still traveling through the house, you are likely dealing with airborne leakage and need to soundproof the entire laundry room.

Soundproof the Door

Installing a Sound Lock Door Seal Kit on a solid core door closes air gaps around the perimeter of the laundry room door will help to block airborne noise from traveling out the door. Even small gaps allow significant sound transmission. Sealing these openings improves containment and reduces noise escaping into hallways and adjacent rooms.

Add Absorption Into the Laundry Room

Adding acoustic material inside the room reduces reflected sound and lowers overall noise buildup. Hard surfaces like drywall and tile reflect sound waves, increasing perceived loudness. Absorptive materials reduce echo and internal reverberation.

If significant containment is required beyond basic treatment, you may need to explore soundproofing the entire room to address structural transmission paths.
