Why Hardwood Floors Squeak? Top Reasons & Solutions

Have you ever been quietly tip-toeing through your home, only to be startled by a loud creaking noise coming from your hardwood floors? If so, you’re not alone. Squeaking hardwood floors refer to the noise produced when you walk on them. The sound can be described as a creaking or squeaking noise, and it’s usually caused by the friction between the boards and the subfloor. The sound can be annoying and disruptive, especially in quiet environments.

In this article, you will learn about the causes, diagnosis, and solutions to squeaking hardwood floors and how to prevent and fix them. So, let’s dive in and end those annoying squeaks once and for all!

Keynote: Why Hardwood Floors Squeak?

Hardwood floors may squeak over time due to loosened nails or screws, causing boards to shift and rub together, creating friction and sound. Factors such as humidity changes, aging, or incorrect installation may also contribute to squeaking.

Anatomy of Hardwood Floors

To understand the causes of squeaking hardwood floors, it’s essential to understand the anatomy of hardwood floors. Hardwood floors consist of multiple layers that work together to provide a durable and beautiful finish. These layers include:

Layers of hardwood floors

  1. Surface Layer: The surface layer is the visible layer of the hardwood floor. It’s the layer that you walk on and see, and it’s made of hardwood.
  2. Substrate Layer: The substrate layer is the layer beneath the surface layer. It provides stability and support to the surface layer and is usually made of plywood or other engineered wood products.

How hardwood floors are installed

Hardwood floors can be installed in several ways, including nail-down, glue-down, and floating installation. Nail-down installation involves nailing the hardwood boards directly to the subfloor. Glue-down installation involves gluing the hardwood boards to the subfloor. Floating installation involves interlocking the hardwood boards and laying them on top of an underlayment.

The role of the subfloor in squeaking

The subfloor plays a crucial role in preventing squeaking hardwood floors. If the subfloor is not level or has structural issues, it can cause the hardwood boards to shift and rub against each other, causing the squeaking noise. Additionally, if the subfloor is not adequately secured to the joists, it can cause the subfloor to flex, which can also cause the hardwood boards to shift and squeak.

Common Causes of Squeaking Hardwood Floors

1. Moisture and humidity changes

One of the most common causes of squeaking hardwood floors is moisture and humidity changes. Wood is a natural material that expands and contracts with changes in temperature and humidity. When the wood absorbs moisture, it expands, causing the boards to push against each other and create the squeaking noise. According to the National Wood Flooring Association, moisture-related issues account for 70-90% of hardwood flooring failures.

It’s essential to keep the humidity levels in your home within the recommended range of 30-50% to prevent moisture-related issues with your hardwood floors. Using a dehumidifier in areas with high humidity can also help. Additionally, ensure that spills are cleaned up immediately and avoid using excessive water when cleaning your hardwood floors.

2. Seasonal changes in temperature

Seasonal changes in temperature can also cause hardwood floors to squeak. When the temperature changes, the wood expands and contracts, causing the boards to shift and rub against each other. This can be exacerbated if the humidity levels in the home are not regulated properly.

To prevent seasonal changes in temperature from causing squeaking hardwood floors, it’s essential to regulate the temperature in your home. Keep the temperature within a consistent range and use a humidifier or dehumidifier to maintain proper humidity levels.

3. Loose nails or floorboards

Loose nails or floorboards can also cause squeaking hardwood floors. Over time, the nails or screws that secure the hardwood boards to the subfloor can become loose, causing the boards to move and rub against each other. This can create the squeaking noise that you hear when you walk on the floor.

According to the Journal of Light Construction, nails that are improperly driven or located too close to the edge of the board can cause squeaking hardwood floors. If you suspect that loose nails or floorboards are causing your squeaking hardwood floors, it’s essential to have them fixed by a professional.

4. Poor installation

Poor installation can also be a cause of squeaking hardwood floors. If the hardwood boards are not installed correctly, they can shift and rub against each other, causing the squeaking noise. It’s essential to hire a professional to install your hardwood floors to ensure that they’re installed correctly and securely.

According to the National Wood Flooring Association, proper installation is crucial to prevent squeaking hardwood floors. The subfloor must be properly prepared, and the hardwood boards must be installed using the correct techniques and tools.

5. Aging and wear and tear:

Finally, aging and wear and tear can cause hardwood floors to squeak. Over time, the boards can become warped or damaged, causing them to shift and rub against each other. Additionally, foot traffic can wear down the finish on the hardwood, making it more susceptible to moisture and humidity changes.

According to the National Wood Flooring Association, hardwood floors can last for decades with proper care and maintenance. It’s essential to maintain the finish on your hardwood floors by using protective pads on furniture and avoiding high heels or shoes with cleats that can damage the wood. Additionally, regular cleaning and maintenance can help prolong the life of your hardwood floors.

6. Subfloor issues

Squeaking hardwood floors can also be caused by issues with the subfloor. If the subfloor is not level or has structural issues, it can cause the hardwood boards to shift and rub against each other, creating the squeaking noise. According to the National Wood Flooring Association, subfloor issues account for 10-20% of hardwood flooring failures.

7. Improper maintenance

Improper maintenance of hardwood floors can also lead to squeaking. If the finish on the hardwood is not properly maintained, it can become worn down and more susceptible to moisture and humidity changes. Additionally, using the wrong cleaning products or methods can damage the finish, causing the boards to shift and rub against each other.

8. Pet damage

If you have pets, their claws can scratch and damage the finish on your hardwood floors, making them more susceptible to moisture and humidity changes. Additionally, pet urine can seep into the hardwood and cause it to expand, creating the squeaking noise.

9. Structural issues

Squeaking hardwood floors can also be caused by structural issues with the building. If the joists or beams that support the subfloor are not properly installed or are damaged, it can cause the subfloor to flex, creating the squeaking noise. In severe cases, structural issues can even cause the hardwood boards to crack or split.

Diagnosing Squeaking Hardwood Floors

Now that we’ve identified the common causes of squeaking hardwood floors, let’s talk about how to diagnose the issue. By identifying the source of the squeaking, you can take steps to prevent and fix the problem.

Listening for squeaks

The first step in diagnosing squeaking hardwood floors is to listen for the squeaks. Walk around the room and try to locate the area where the squeaking noise is coming from. It’s important to note that the squeaking noise may not be coming from the area where you hear it, as sound can travel through the floorboards and subfloor.

Visual inspection of the floor

Once you’ve located the general area where the squeaking is coming from, visually inspect the floor. Look for any visible signs of damage or wear and tear, such as cracks or gaps between the boards. Check the area around the squeak for any loose nails or screws.

Using a moisture meter

If you suspect that moisture or humidity changes are causing the squeaking, use a moisture meter to test the moisture levels in the hardwood. A moisture meter measures the moisture content of the wood and can help identify any areas that may be absorbing too much moisture.

In some cases, it may be necessary to remove a section of the hardwood floor to fully diagnose the issue. This is especially true if the subfloor or joists are suspected to be the source of the problem.

Fixing Squeaking Hardwood Floors

Now that we’ve identified the common causes and diagnosed the source of squeaking hardwood floors, let’s talk about how to fix the issue. The appropriate fix will depend on the cause of the squeaking.

1. Tightening loose nails and boards

2. Using screws instead of nails

Screws are more secure than nails and can help prevent future squeaking. If you’re replacing nails, consider using screws instead. Make sure to use screws that are long enough to penetrate through the hardwood and subfloor but not so long that they penetrate the joists.

3. Adding shims or felt pads

If the squeaking is caused by gaps between the hardwood boards and the subfloor, adding shims or felt pads can help. Shims are small wedges that can be inserted between the subfloor and the hardwood to eliminate gaps. Felt pads can be placed between the hardwood and subfloor to reduce friction and prevent the boards from rubbing against each other.

4. Replacing damaged or worn floorboards

If the hardwood floorboards are damaged or worn, they may need to be replaced. This is especially true if the boards are warped or cracked. To replace a floorboard, use a circular saw to cut out the damaged board and remove any nails or screws. Cut a new board to size and install it using the appropriate installation method.

5. Refinishing the floor

In some cases, refinishing the floor may be necessary to prevent future squeaking. Refinishing involves sanding down the hardwood and applying a new finish. This can help protect the hardwood from moisture and humidity changes and prevent future wear and tear.
