How to Fix Squeaky Floors

A squeaky floor can often become a major annoyance in a home or business, even if some people just put up with it as a sign of floor aging. If that’s happening to you, some methods exist to fix the problem yourself.

That squeak sound you hear are nails moving in and out of the floor’s joists. The subfloor is separating from the joists in this scenario.

Fixing this problem is a DYI household task you can definitely do on your own if you’re capable of working with basic tools. If you never have done it before, it’s still fixable hiring a professional floor repair specialist.

What’s the Simplest Fix to a Squeaky Floor?

For the more thorough fixes, it’s better to have access to the subfloor and the joists. If having a basement, you can fix your floor by literally going underneath it to fix all issues.

When that’s not possible, you can use something as simple as a dry lubricant on wooden floors to stop squeaks.

While this is the simplest and easiest method, other natural items like talcum powder can be used on noisy joints in floorboards.

In a scenario where you do have access underneath your floor, you can do a more thorough job making sure the squeaks don’t come back any time soon. After all, if you were used to a silent floor for years, having to put up with squeaks could drive you crazy.

More Relatively Simple Fixes

If managing access to your subfloor, you’ll be able to do a more detailed job stopping that squeak for a good number of years.

To start, find a piece of solid wood to fasten against the joist in your floor. Make sure it fits firmly against the subfloor so it doesn’t move out of place later. The point is that the wood piece will support the subfloor and prevent the nails from squeaking in the joists.

Using wooden shims to fit into the floor/joist gap is also a workable solution if the gap is small. Even a small screw sometimes works to fasten a floor to a subfloor if the two happened to separate.

If you have finish nails available, many flooring experts recommend hammering a nail into your floor where the squeak is. Just be sure the nail is going into the floor joist.

Using Pieces of Wood to Stop the Squeak

Using blocks of wood can often help the squeak problem if being able to work under your floor in a basement. While adding wood is a little more complicated, it’s not overly problematic if you’ve worked with wood before.

When joists start to warp, nailing a 2×4 block of wood along the joist will help eliminate squeaking problems. To make the woodblock stay in place, use an adhesive used in the construction industry. Simply place the wood under the subfloor and to the joist.

To secure the above wood piece, you can use drywall screws to ensure it never loosens. Make sure the screws are placed eight inches apart from one another. It’s usually recommend you add more screws on each end of the block to ensure it never loosens.

Two Practical Ways to Eliminate Squeaks Without Construction Work

A common culprit for a squeaky floor is low humidity. Since climate is different depending on where you live, living in places where the air is dry could dry out a new wood floor within a few years.

By buying a humidifier, you might be able to stop the squeak without having to use construction adhesives, nails, or blocks of wood. Not that certain practical products aren’t available on the market to stop squeaks from the top side.

For instance, a popular device called Squeeeeek-No-More-Wood Floors is available. It allows you to drill screws into the floor in seconds, then snaps off the screw heads for a more secure solution.
