How to Fix Squeaky Floors Under Carpet

By Ann Hills / a couple of years ago

Nothing can be more frustrating than waking up and walking on the floor just to hear the sound of your floorboards squeaking. Especially when you have woken up early on your own, and don’t want to wake the rest of the house. The good thing is that it can be fixed. Whether it is your bedroom or your hallway floor, with the right tools and a good ear to the ground, you will be able to fix the squeaking noise easily.

Here is a guide on how to fix your squeaky floor under the carpet.

Gather Your Equipment

Just like with any other repair job in your house, you will need to prepare the right equipment to fix the floorboards: get a floor repair kit, drill, hammer, and a tripod fixture. You can easily find all of these tools at any hardware store, so it will not take you long to collect them all. You might find that you will not need all of them and in that case, there’s no need to get them all.

Find The Source

This step could be tricky; it will need a little bit of experimentation with your legs and ears. Simply, walk over the floor and determine where the exact source of squeaking is. If there is more than one source of noise, you can mark them with a sticky note. Keep in mind that not all floors might be easily fixed, and some might even need to be installed over. But should you install a new floor over your tiles? This common question can be answered after you determine their condition. For example, if your tiles make noise, but they seem to be in good shape, then you can fix them with the few solutions mentioned here. However, if they seem to be in poor condition, then you will need to install a new floor.

Finding the source means that you found the joist, making the noise. You can then go about fixing them from above or from below. If you are going to do the fix from above, then the tools mentioned will suffice. However, if you decide to do the fix from below, then you’ll have to find the joist on the floor below. The light fixtures below are usually screwed to the joists, so you will remove them.

Fill The Gaps

You can apply this fix if you found the joist with the problem from below. Have someone help you by going on the floor above you and walking. Once you hear the noise, tell them to stop and use a flashlight to see if there’s a gap in that area. If there is, you can apply glue to fill it or insert shims to close it. Just be careful as you insert the shims so you dent the floor above. The purpose of this step is to fill the gap without causing damage.

Strengthen The Joist


Joists are mostly made of wood, and like any other piece of wood, it is prone to shrink, twist, deteriorate due to mold, or curve. This can create a space between the wood and the subfloor, making that annoying squeaking noise every time someone walks on it. To fix this, you can install a woodblock alongside the joist. Apply a layer of construction adhesive along the top, and then hold it against the joist and the subfloor with nails. You can screw it in to keep it more fixed in place.

Use Tripod Fixture

You can use this method without damaging the carpet. Use the driver by inserting it in your drill and putting the screw at its end. Next, push this through the tripod fixture, and drill through the carpet into where the joist supposedly is. You will hear the noise of the drill as it goes deeper, until it reaches as far as it can go. This way, the subfloor will be pulled against the joist in a way that will prevent the squeaking.

Prevent Joists From Making Noise

This fix is also pretty simple. You can add blocks between the joists, which means that you will have to find a wooden block and cut it so it can fit in the space between the joists. Be careful not to cut it too big so that it fits tightly, or this might inflict damage on your subfloor or joists.

Fixing your squeaky floor can be easy. You just need the right tools and a good ear. While this project is simple, it may take some time to determine which place is causing the noise. But whether you tell someone to walk on the floor or use the hammer to determine the source of the noise, you will certainly be able to fix the problem with a few simple steps.
