I live in a small apartment which is mostly really silent, but every time I used to turn on the washing machine it would be just about 1:30 hours of unbearable noise.
I did some research and purchased some soundproofing materials. After installing them, I am now still able to hear the washing machine, which is a naturally really loud one, but I got it down to a very manageable level.
To be honest, the difference was extraordinary.
If you follow these steps, then you should be able to achieve the same results, maybe even better ones.
Soundproof the Washing Machine
The first step is to start at the source, there are many other things you can do like soundproofing the door, which I’ll get to in a moment, but first make sure to make the washing machine itself as quiet as possible.
How to do this?
Get Washing Machine Pads or Mat
The vibrations coming from the washing machine are easily transmitted through the structures of your home which means that they are harder to deal with than regular sound.
This would be the low rumble you can often hear when you turn the washing machine, and also the dryer, on.
The easiest fix for this is to get anti-vibration pads.
These pads are very affordable, easy to install and will completely change the overall noise the washer makes since the vibrations are being absorbed.
Another quick and easy fix would be to use an anti-vibration mat. It is a bit more expensive but it’s even easier to install and it will also absorb the vibrations damn well.
How to install them?
The installation of the mats and pads if fairly straightforward; Move the washing machine from its current location and lay down the pads or mat.
Next simply move the washing machine back to its former position making sure that you put it on top of the pads/mat.
You could use folded-up old hand towels as vibration pads which should also work. Just know that the real pads will be a lot better at absorbing the washing machine’s vibration.
Level the Washing Machine properly
If the washing machine isn’t properly leveled, then every time you turn it on it will bump and knock against both the floor and the cabinet that it’s in.
The sound absorbing pads/mat should help with this, but you could also use some foam to level it.
Check for loose parts
Loose parts in the washing machine like screws or panels will make noise once you turn it on.
Simply look at the panels and screws you can find and check if they are loose. If they are, use a screwdriver to put them back into place.
Use sound absorbing foam
Cut small pieces of acoustic foam and place them behind the washing machine and also on its sides. You can use duct tape to attach them to the washer.
Basically, you want to put foam in every place where there is space between the washer and the wall/cabinet.
This will help deaden the sounds a little bit, but it will also help avoid the machine bumping against the wall/cabinet.
For soundproofing the washing machine itself, these would be the options.
The next step would be to soundproof the door…
Soundproof the Laundry Room’s Door
Soundproofing a door is really simple and it can be done fairly quickly, you may need to purchase a couple of things to do this, but they aren’t expensive at all.
The most important thing when soundproofing a door, or anything for that matter, is to seal off any gaps where sound may be allowed to come in.
How do you do this?
Use Acoustic caulk
Acoustic caulk is easy to apply and very effective. You will need to purchase this acoustic caulk and apply it using a caulk gun.
How to use Acoustic Caulk?
It’s designed to fill small 1/8” gaps to ½” gaps and should be applied between the frames and the door.
Make sure to properly check where it needs to be applied and don’t leave any gaps or cracks unsealed.
It’s designed for interior use only; it shouldn’t be used on the exterior!
Note: After you have applied it, give it about 48hs to dry completely.
Applying high-density foam tape is one of the most effective ways to soundproof a door. As a bonus, it won’t just help with soundproofing but also with temperature insulation.
This tape is extremely affordable and easy to install, since it has an adhesive side, so you won’t need any glue.
How to apply a Weatherstrip
Tape it around the entirety of the frame where it will be in contact with the door once it’s closed.
If done properly it should form an air-tight seal which will prevent a lot of the sound from coming in to the room.
This is the weatherstrip that I recommend, since it’s affordable and of extremely good quality, it should last you for a very long time.
Tip: If air can come in, then so does sound. This means that you should close the door and feel if there’s any air entering through any gaps that you still haven’t sealed.
Another way to check for gaps and cracks is by using a flashlight. If everything is sealed up perfectly, no light should be seen between the door and the frame.
This takes care of the gaps between the door and the frame, but there is usually a big gap between the door and the floor, which brings me to the next step…
Install a door sweep
What you need to get here is a door sweep like this one and cut it to the size of your door.
Once the door sweep is in place you could use the same acoustic tape you used for the door frames and apply them to the door sweep. This will further help seal the bottom of the door.
Get some Acoustic blankets
Acoustic blankets are one of the best things you could use to soundproof anything for two reasons; they are quite good at their job and they are extremely affordable.
Placing some acoustic blankets over the door and the windows will further help with soundproofing the laundry room since the blankets absorb a lot of the noise, not allowing it to leave the room.
The ones I’d recommend for this particular case are the Sure-Max Ultra thick Moving Blankets.
You can get a pack of 12 blankets, which is super cheap, and use more than one in the laundry room, plus you will have some left for other purposes.
Use Mass Loaded Vinyl
One of the best sound insulation materials out there is Mass Loaded Vinyl. It is used mostly to soundproof cars, but it can be used to soundproof anything you want.
Two things to consider: Mass Loaded Vinyl is quite heavy, which means that you will need to properly attach it to the door, also it only comes in black, if you don’t mind this then by all means, hang it like that, but you could purchase some fabric and make it look nice.
How to do it?
You will need some mass loaded vinyl, Velcro and any type of fabric that you want to use to make the vinyl look better.
Simply cut the vinyl to the shape and size of the door and use the Velcro to attach it to where it needs to be. Otherwise you could insert some grommets into the edges to allow for some easy hanging.
The Velcro is a better solution since it will create a better seal.
Use Soundproofing materials on the walls
Any sound-absorbent material you can fit inside the laundry room will help with keeping that noise in that room.
I’ve already talked about soundproofing blankets since these would be the easiest to install, but installing some acoustic panels like these ones will also help, even more than the blankets.
If these panels are too expensive then you could go for some regular acoustic foam panels.
By far the easiest thing to do is to install the anti-vibration pads/mat. If this solves your problem then that’s it, you’re done.
However, soundproofing the door properly is one of the best things you could do, you’ll be amazed at how much noise you can reduce by just doing this.
I really hope this information was useful!
