How to fix squeaky hardwood floors from the top

Creaky, noisy floors are a big nuisance and you may not know what tools you need to fix them.

Fixing, or at least reducing the squeaks and creaks in your floor is a very doable DIY project for most people.

Here are the tools you need to fix creaky floors:

Tools you probably already have to fix a squeaky floor

You likely already have some of the tools you need to stop a floor from squeaking:

• 1” wood screws
• 2” finish nails
• Nail set
• Drill
• ⅛” drill bit
• Philips head screw driver
• Adjustable wrench
  

One other item you must have before working on your wood floors is a good putty or filler that matches the color of your hardwood floors to fill in any holes you make from screws or nails.

I like ColorPutty products because they are easy to work with and blend multiple colors together if needed.

ColorPutty will harden but remain flexible so it won’t dry out and crumble out of the hole.

Tools to fix creaky wood floors from above

Maybe you don’t have easy access to your floors from below through an unfinished basement or crawl space.

Don’t worry! There are tools and methods you can use to eliminate squeaky floors from above.

Using finish nails to fix creaky floors

Using 2” finish nails and a hammer you can nail down wood flooring boards that are moving and causing squeaks. Be sure to only nail along the joists that support your floor.

A nail set can then be used to hide the top of the nail below the surface of your flooring.

Then use putty or filler to hide the nail hole.

Try the “Squeeeeek No More”® breakaway screw kit for wood floors

This breakaway screw kit is a great buy to help solve creaky floor problems. Screws have much better holding power than nails and don’t have to be used over joists.

The “Squeeeeek No More”® includes unique breakaway screws and a special plastic fixture that will automatically snap off the screw slightly below the top of your floorboards so you can then cover the hole with putty.

You will need to use your drill and a ⅛” drill bit with this kit.

You can use baby powder or WD-40 to fix squeaky boards in your floor

Ok, this sounds a little weird – but you can actually try using baby powder or even WD-40 to stop some wood floors from squeaking.

This tip really only works if you have two or more boards that are moving and rubbing against each other. It may be that this movement and friction is the source of your squeak.

Baby powder or WD-40 can act as a lubricant and stop these boards from making noise. Be careful to wipe up any excess lubricant after working it into the edges of the boards that are squeaking. You don’t want anyone to slip!

Tools to fix squeaky floors over carpet

Do you have a creaking floor covered in carpet? I can tell you right now that the carpet isn’t the issue – your squeaking and creaking noises are coming from your subfloor.

Fortunately, there is a “Squeeeeek No More”® breakaway screw kit for carpeted floors that includes everything you need except a drill to find the joists underneath your carpeted floor and fasten breakaway screws to your subfloor that will be hidden safely under your carpet.

Tools to fix squeaky wood floors from below

The best way to fix a squeaky wood floor is usually from below if you have access to your floors through an unfinished basement or crawl space.

You can often see the movement and source of your squeaks from below while having someone walk on them above.

These are the tools and methods you can use to fix creaky floors from below:

Use wood screws to stop movement that causes squeaky floors.

If you suspect there are areas in your flooring where there is space or air between your subfloor and floor boards you can try driving 1” wood screws into your subfloor from below to tighten these areas and stop the movement that causes squeaks.

Use wood blocks or shims to stop creaky wood floors

While looking at your floors from below you may notice there are areas where there is a gap between your subfloor and the joists that support them.

When people walk on this area there will likely be movement that causes the creaks and squeaks that you hear.

Screw wood blocks on either side of your joists to support your subfloor or insert wood shims into the smaller spaces above your joists. It will help to use construction adhesive along the joists to help secure them.

Try the Squeak-Ender product to eliminate noise in your wood flooring

An inexpensive fastener kit called the Squeak-Ender will help you to tighten your subfloor to your joists to stop the movement that causes squeaks.

You may need several of these kits depending on how wide spread your squeak issue is. You’ll also need a Phillips head screw driver and adjustable wrench to install this kit.

Take the next step to your perfect floor

In order to fix your creaky floor you first have to identify where the squeak is coming from.

Movement is what causes wood floor squeaks.

Once you find out where the movement is happening you will have a good idea which method and tools to use to make that noise go away.

I’ve written a comprehensive DIY guide to solving wood floor and carpeted flooring squeaks. I go through each of the tools listed here and tell you step-by-step how to use them.

Everyone knows the frustration of squeaky floors. You wince when you walk around late at night, trying not to wake up the whole house. Maybe the kids have a little too much fun rocking back and forth on the loudest part of the living room floor. No matter where it is, a loud hardwood floor is a nuisance in your home. Fortunately, this is a problem that you can fix. Movement is the cause behind all squeaky floors. To fix the issue, you must first determine what is allowing your floor to move. This might be temperature fluctuations, an uneven subfloor, or joist issues. Once you locate the source of the movement, you can stabilize your floor and eliminate the noise. To help you along the way, here’s our guide to the common causes of squeaky hardwood floors and how to fix them.

Seasonal Problems

When you hear a squeaky step for the first time, don’t panic. Instead, ask yourself what the weather is like. Engineered and solid hardwood floors consist of real, natural wood. This means that your floorboards will expand and contract with seasonal temperature changes. A little fluctuation in your floors is perfectly normal. If your floors start to squeak in the middle of winter, it simply means that dry winter air and the heater in your home have caused your wood floor to contract. This contraction gives your floorboards more room to move, which makes it more likely for your planks to rub against each other or the fasteners holding them in place. Seasonal squeaks are common and frequently fix themselves once temperatures and humidity levels rise again, causing your floor to expand. However, you can help avoid the problem by keeping your home—especially any rooms with hardwood flooring—at a stable humidity level of 40 to 60 percent.

Joist Problems

Joists are a structure beneath your floor and subfloor. These horizontal bars help make up the framework of your floor. In a properly functioning room, the joists stabilize your subfloor and prevent movement from occurring. This means that any problems with your joists will likely result in loose flooring that creates unwanted noise. Issues with your joists can include loose or warped joists or gaps between your joists and your subfloor. If you suspect joists are the source of your squeaky floors, you will need access to the basement or room beneath the flooring to confirm. This will let you look up at the joists supporting your floor to identify any issues.

Subfloor Problems

Sometimes the issue doesn’t stem from your top floor or your joists, but from the subfloor itself. Uneven subfloors are one of the most common issues that can cause a squeaky floor. When your subfloor isn’t level, it creates empty space between itself and the top floor. This space allows for movement of the top floor, which then creates noise. You might also have a misalignment or empty space between your subfloor and the joists. The quality of your subfloor can also cause issues. If your subfloor is old or has suffered water damage, it won’t be able to hold nails and other fasteners as well. This leads to a loose subfloor or top floor, both of which can shift and cause squeaks and creaks.

How To Fix Squeaky Wood Floors

Identifying the source of movement in your floors is the first step to solving the issue. Once you know where the issue comes from, you can then choose the best method of fixing it. Remember that you might not need to reach for the power drill right away. Seasonal fluctuations and other minor problems might right themselves once the humidity in your home is back to normal. However, if the problem persists, you can tackle the issue with one of the following methods.

Install Shims

Many squeaky floor solutions require access to the joists and subfloor. If you inspect the area beneath your floor and you find a gap between the joists and the subfloor, you can fix the noise by inserting a thin wooden shim. Pinpoint the exact source of the noise and the gap that exists there. Gently wedge the shim into place. You can also use a bit of carpenter glue to ensure the shim stays. Be careful when shimming your joists and subfloor, as wedging the piece in too hard can accidentally create an even larger gap between the two.

Use Construction Adhesive

Installing a shim can only fix a specific and isolated gap in your joists and subfloor. If you find a gap that is too long for this method, you can use adhesive instead. Construction-grade adhesive allows you to fill and secure longer gaps, cracks, and other empty spaces between your joists and subfloor. A caulking gun is the easiest way to install your adhesive directly into the gap. If you use this method, be sure to check both sides of your joist and fill any gaps you find.

Stabilize Warped or Noisy Joists

Like your hardwood floors, joists can also warp or twist over time. This creates an uneven frame for your subfloor, leading to gaps and unwanted noise. Fortunately, there are ways to stabilize your uneven joists. If warped boards are the issue, secure them by installing planks along the joist. Attach the plank to both the joist and the subfloor above to anchor them together. You can also install blocks of wood between two joists. These wood blocks will help stabilize your joists and the subfloor to prevent movement.

Screw from Underneath

If your joists are fine but your subfloor is loose, one of the best ways to solve the issue is to secure the subfloor to your top floor. You can do this by screwing from the underside of the subfloor into the bottom of your top floor. This will hold your subfloor and your top floor together and get rid of any gaps that cause shifting and creaking. If you use this method, take extra care not to drill too far through your finished top floor.

Screw from the Top

Not all homeowners can access the area beneath their squeaky floors. If this is the case, you can still fix the issue by screwing or nailing your top floor to the subfloor or the joists. However, this method makes it harder to disguise your repairs. If you screw your floors down from above, be sure to countersink the screws or nails to eliminate any sharp edges. You can also hide any leftover holes with wood filler or scratch concealer to make the repair look as neat as possible when you’re done.
