Last Updated: June 1st, 2019

If you are like many others that are interested in soundproofing your windows, you may not know where to begin. It’s pretty easy to hire a professional who knows how to do soundproofing to do the work for you, but if you are a DIY enthusiast like myself who loves to do things on your own and probably see an opportunity to save some money by doing it yourself.

You might think that learning how to soundproof a window might be hard. But to be honest, doing it yourself it might just take a small investment from your pocket and a few hours of your time. You can avoid all these issues by just installing soundproof windows but this might not be the remodelling your looking for plus you’ll also need a professional to do the installment.

If DIY soundproof windows seem to be your thing, here are some tips you can follow to get you started.

How to Soundproof Windows Yourself

If you live in a noisy neighborhood, I bet you would try everything in your power to block out all the annoying noise from street traffic and early morning garbage truck without having to pay for professional help. I actually learned a lot when soundproofing my windows. For me, it was more of an experiment when getting started and I just went with whatever I taught was best for me.

There are many ways to soundproof your windows, each with its own pros and cons, in general. Getting started you’ll need to install something that can absorb and dampen the sound.

1. Soundproof Window Seal

As you look closer on your windows you may notice a few tiny gaps and cavities, these are what causes noise to come in and bother you. So it’s very important that we inspect the window for any tiny air gaps and seal them quickly to block soundwave from passing through. If you live in a modern building, then you shouldn’t be worrying because modern window frames should be sturdy built, but it’s a good idea to check anyway.

The best way to cover all these gaps would be to seal the windows completely, but this is very impractical. Thankfully there are few tools you can use to get the job done. Let’s look at some simple and cheap ways to get rid of these air gaps.

First Seal All Air Gaps

First to get the most out of soundproofing is to entirely block the window. Make sure to properly identify the cracks and spaces around the window. You can do this by placing your hand around the edges and if you feel any air coming in then that’s the spot you are looking for. Make sure to mark the spots so you don’t have to go over the same process.

Now that you have identified the area to seal, you can use a Green Glue Noise-proofing Sealant to fill these gaps and cracks to prevent sound from pushing through. The Green Glue Noise-proofing Sealant is specially designed to fill up cracks and gaps. It’s very easy to apply and dries in 48 hours.

2. Choose Thick Blinds

One way to reduce the noise level in your home is to install blinds. Blinds can be very helpful to reduce echo in the room. They also offer an additional but minimum sound blocking. I wouldn’t consider thick blinds to be as effective as a sound deadening curtain, but they can surely improve things a little bit.

If you are thinking of using blinds on your windows, then I recommend the ones that are made of thick materials. For my home office, I used Calyx Interiors Cordless Honeycomb. They did have an impact on the sound dampening but the difference wasn’t that huge. However, I like the fact that this honeycomb is able to let in a little light because I did not want my home office to be too dark.

3. Replace The Windows

If you are willing to break the bank and spend a good amount of money then you can consider replacing the window entirely. This is an expensive route that will probably cost you about $850 or even more dependent on labor. At the same time, this is one of the most effective ways to go. Double pane windows reduce the amount of noise significantly. Other than sound dampening, double pane windows reduce heat transmission as well.

There are a number of local hardware stores or anywhere that specialize in windows. One thing to remember if you are entirely replacing the window is to make sure whoever is doing the installation does it correctly. Because if there are still cracks in the sealant, the sound will find its way back in.

4. Consider Sound Deadening Curtain

One of the simplest solutions for soundproofing a room is soundproof curtains. Although sound deadening curtains are not 100% entirely effective, they can be very helpful in taking the edge off sound coming from outside the window. Since these curtains look appealing in the room, it’s a good upgrade, it will make the room look a lot nicer and can even be used to conceal any foam that has been used on the windows.

I’ve personally used these curtains in my room, what these curtains do is help reduce the echo from within a room. The curtains are made of high-quality material that soaks up any sound which will make the room feel much quieter and more peaceful. If you want to get the most out of your soundproof curtains, you’ll need to get more panels than normal so that they thickly cover the windows areas. If you are interested then I recommend buying NICETOWN Blackout Curtains Panels for Bedroom. These curtains are very effective, they are really dense due to their triple weave design. It’s great at keeping out light, cold and sound.  

5. Window Foam

Using window foam is one of the cheapest options on our list for soundproofing your windows. However, there are many different types of window foam, from triangle to wedges to pyramid, but the shapes don’t really matter. When buying a foam the most important factor to consider is the thickness. Make sure that the foam is at least two inches thick.

The foam may not be the best option to soundproof your windows. It likely won’t make a big impact and also having a foam covering your stunning windows can negatively affect the aesthetics of your interior.

6. Furniture for Soundproofing

You can help reduce the noise coming from your windows by placing the right furniture near the windows. This is a trick I’ve used before in the past, although it won’t make a noticeable difference, it can help to enhance the noise reducing benefits of your other soundproofing method.

You can start by rearranging your existing furniture or add some new pieces. If you want to block the window completely we recommend placing a closet, a heavy couch, desk or other furniture in front of it. But if you don’t want to lose the precious light, you can start by placing the furniture around the window or next to it. These materials will absorb some of the sound waves forcing their way through the window.

Using this method will not cost you a penny, so there is absolutely no reason why you shouldn’t try it out today!

Cost For DIY Window Soundproofing

Sometimes you may end up saving about $700 in fees. However, the soundproofing method such as installing new windows should be done by a professional who has adequate skills.
