Soundproofing a kitchen may make your family’s life a lot more pleasant, especially if you live in small apartment where everyone around can hear what’s going on inside the kitchen.

Some noises like the ones coming from the sink, or even the range hoods can be quite frustrating, but luckily, they can be reduced!

1. How to soundproof the kitchen door

If you want to keep the noises created in the kitchen INSIDE the kitchen, then soundproofing the door is by far your best option.

If sound isn’t allowed to leave through the door, this means that the noises generated in the kitchen won’t be able to reach the rest of the home.

When soundproofing anything you should focus on sealing every gap or crack you can find where sound can be allowed to come in or out.

Step 1: Apply a Weatherstrip

One of the best, if not THE best, solution to soundproofing a door is to apply a weatherstrip.

It’s a great choice because of three reasons; It’s cheap, easy to apply, since it’s got an adhesive side, and if applied properly it will form an air-tight seal once the door is closed.

This means that it’s going to be really hard for sound, as well as air and also smells, to get through.

It needs to be adhered to the frame, more specifically to where the door will meet the frame once closed.

Take measurements and cut the weatherstrip to the exact length required.

Next simply adhere it to the frame.

This should be done around the entirety of the frame. Remember that you will need to seal as much surface as possible.

This is the weatherstrip I recommend, there’s no need to get anything more expensive, really, since it will work perfectly.

You may wonder how to deal with the gap left between the door and the floor, since you can’t use the weatherstrip here…

Step 2: Install a Door Sweep

The next step is to install a Door Sweep, which will help with sealing the gap between the door and the floor.

This won’t create as tight of a seal as the weatherstrip but it’s the only thing you can really do here.

First get a Door Sweep like this one.

Next, cut it to the exact size of your door, making sure that it covers the entirety of the gap.

Lastly, install the Door Sweep. This one in particular doesn’t require you to use any tools since it comes with an adhesive side.

If you have any cracks between the frame of the door and the wall, then I’d suggest you purchase some Acoustic Caulk.

Step 3: Apply Acoustic Caulk

This is extremely easy to do; it’s fast and very effective.

You need to get this Acoustic Sealant and using a caulk gun you can begin the installation.

Where 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.

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.

Step 4: Install MLV on the door

Mass loaded vinyl is a fantastic soundproofing material which is used for a variety of purposes, from soundproofing walls, doors to even cars.

Cutting some vinyl and installing it on the door, especially if it covers the entirety of it, will further reduce unwanted sounds by a lot!

To attach it to the door I’d advice you to use this high-quality Velcro, making sure to adhere as much of the Velcro to the door as you can, since MLV is quite heavy.

2. How to soundproof the kitchen windows?

Just like with the doors, when soundproofing windows, you first need to make sure that all the cracks and gaps are perfectly sealed.

After this you can consider maybe changing the glass do double- or even triple-pane and installing curtains, etc. But first focus on sealing the gaps which is the most important step.

Step 1: Weatherstrip the windows

Here you can use the same weatherstrip that I recommended for the doors.

All you need to do is cut it to the appropriate size and adhere it to the frame or the window, making sure that there’s not a single gap left open once you close the window.

Step 2: Use acoustic Caulk

Again, the same acoustic caulk that I recommended for the doors can be used here.

It should be used primarily to seal off any gaps or cracks that should have formed between the frame and the walls. This tends to be a common occurrence with older windows.

Step 3: Acoustic Curtains

Acoustic curtains are one of my top choices when it comes to soundproofing a window.

Not only are they very cheap and dress the room, but they are also highly effective.

You can get them in a variety of colors which will allow you to use them not just for soundproofing purposes, but also for decoration, since they actually look quite nice.

To be effective, a soundproof curtain has to be heavy, thick and tightly woven, but arguably, more important than this, is that they have to cover the whole window and more. They should go from ceiling to floor and also a couple of inches past the sides of the window.

If they are wider than the window, then this means that the curtain itself will have more folds which will help seal it off better.

My recommendation for the best soundproof curtains are the NICETOWN blackout soundproofing curtains. They are super affordable, easy to install and work quite well.

3. How to soundproof the kitchen walls?

Here it gets a bit tricky mainly because hanging acoustic foam/panels/blankets can be dangerous because they are a fire hazard.

The options you have here are the following two;

Step 1: Add an Extra layer of Drywall

Even though this might be a lot of work and more expensive than the other steps in this guide, it really does work.

Vibrations generated by sound reverberate, which means that they will be able to travel through the walls unhindered.

Installing extra layers of drywall will help keep the noises at bay. Just make sure to use acoustic caulk between the drywall sheets in order to get a proper seal.

After this you can add a layer of soundproofing paint and you’re done.

Step 2: Use Soundproofing Paint

Soundproofing paint can also work lower the amount of noise that is allowed to leave the room. The great thing is that all you need to do is go to your local hardware store and purchase some.

You can use it on the drywall you just added or, if you decided not to go that route, then simply painting the existing walls will also help.

Note: It can also be used to further soundproof the door.

Make sure to apply as many coats as possible in order to get the best results.

4. How to soundproof a Kitchen Sink?

Soundproofing the kitchen sink might seem pointless to some of you, but this is only if you ever had to deal with good quality sinks.

The more affordable stainless-steel sinks are not known for being soundproof, quite the opposite in fact.

Luckily there are a couple of ways which should help a lot with this;

Option 1: Use a sound deadening mat

Sound deadening mats are typically used to quiet road noise in a car, and they will also work wonders for your kitchen sink.

The ones that I’d recommend are the sound deadening mats by Noico since they offer great quality at a lower price than many of the other brands.

If your sink already has some pre-installed soundproofing, then you should remove this or consider installing the new mat on top of it.

Step 1: Cut the Mat to fit

Before you cut you should position the mat on top of the bowl to get an idea of what the ideal position for it should be.

If you aren’t confident that you will be able to cut the mat properly, consider using a sheet of paper to make a template and fit it over the bowl.

Now all you need to do is cut the mat, making sure that it will cover as much surface possible.

Note: You might need to use two sheets, depending on the size of the bowl.

Step 2: Clean the bowl’s surface with Rubbing Alcohol

Since these sound deadening mats have an adhesive side, you won’t need to purchase any glue, but for them to adhere properly it’s extremely important to clean the surface as thoroughly as possible.

Rubbing alcohol is perfect for this, just use some cotton balls to rub the sink with the alcohol.

Step 3: Install the mats on the sink

Now, all that’s left to do is to remove the adhesive backing and install the mats.

This should be done carefully; you don’t want to have to remove it and re-install it since this will harm the adhesive.

Option 2: Install Mass Loaded Vinyl

Mass loaded vinyl is by far one of the best soundproofing materials available right now, if there is something that needs soundproofing, MLV should be one of your go-to options.

MLV doesn’t normally come with an adhesive backing, which means that you are going to need some strong glue adhesive like the3M super 77 spray adhesive.

The installation is extremely simple, just follow the same steps for installing the sound deadening mat, but in this case the adhesive is 100% required.

Option 3: Use a Rubberized Undercoating

If you’re looking for a quick way to reduce some of the kitchen sink’s noise, then you should consider investing in some rubberized undercoating spray.

If sprayed on the underside of the sink it will help reduce unwanted noise by absorbing them.

Sure, this method might not be as effective as the other two, but it’s certainly easier and more affordable.

5. Consider investing in a new Range Hood

Range hoods are essential in any kitchen, otherwise getting rid of the smells will take forever.

I’ve been looking for ways to reduce the noise my range hood makes but had little to no success with it.

The only thing that worked just a little was cleaning it thoroughly, but this made only a very small difference.

If the noise from your range hood itself is too annoying, then I’d recommend that you purchase a new one that’s designed to work as quietly as possible.

The Broan 424204 ADA Capable Under-Cabinet Range Hood is one of the quietest range hoods on the market and it’s designed for small to medium sized kitchens.

Conclusion

Soundproofing a kitchen requires a couple materials and some handiwork, but you should be able to completely soundproof it in a matter of hours.

Start with the door and see if it’s enough, if it isn’t then just continue with the other steps as described.
