How to Repair Squeaky Floors Through Carpeting

Maintaining a professional and comfortable environment is key to success for business owners of small to medium businesses.  A squeaky floor can not only be annoying, but it can also impact the perception of your business. You might wonder how to fix squeaky floors under the carpet without professional help and incurring high costs. This blog will guide you through repairing squeaky floors through carpeting. Following our step-by-step guide, you’ll learn how to efficiently and effectively eliminate those annoying, disruptive noises, saving time and money.

Causes of Squeaky Floors

Understanding the causes of squeaky floors is the first step in the repair process. Let’s delve into the common reasons behind this issue, equipping you with the knowledge needed to eradicate the problem at its root.

Causes of Squeaky Floors Over Time

Floors begin to squeak over time primarily due to the natural wear and tear of building materials. As wooden floorboards and joists dry out and shrink, they can rub against each other or against the nails securing them, causing the characteristic squeak. Similarly, in the case of carpeted floors, the padding beneath can wear thin over time, leading to increased friction and noise.

Sub-flooring and Floor Joists

Sub-flooring and floor joists play a significant role in floor squeaks. Sub-flooring, typically made of plywood or oriented strand board (OSB), can become loose over time, leading to movement and friction sounds. Similarly, floor joists supporting the sub-flooring can contribute to squeaking when they dry and shrink, creating gaps where they once were tightly secured.

Squeaky Floor Repair with Carpeting

To learn how to fix squeaky floors under carpet, you’ll first need to gather some essential tools and materials. The right equipment will ensure an efficient repair process and a successful result. Let’s delve into what you’ll need to quieten those pesky squeaks.

Tools and Materials Needed

For this task, you’ll require a few essential tools and materials. These include a specialized carpet repair kit, which commonly contains a depth control fixture, alignment, and breakaway screws. A drill for tightening screws into the floor joists, a stud finder to locate said joists, and a tape measure to ensure accurate placement of screws. Lastly, a utility knife could be handy if you need to adjust your carpet.

Right Materials for a Lasting Fix

Choosing the right materials is paramount for a lasting fix. High-quality, durable tools and materials ensure the repair stands the test of time, eliminating future squeaks. Investing in a quality carpet repair kit and sturdy screws specifically designed for flooring applications can make all the difference between a temporary solution and a long-term fix.

Locating the Squeaks

The first step to fixing squeaky floors under the carpet is pinpointing their exact locations. Let’s walk through how to accurately locate the squeaks on your floor.

Selecting the Exact Location of Squeaks

Identifying the exact location of the squeaks involves a simple yet crucial process. Walk across the carpeted area carefully, paying close attention to any squeaking sound. You may find it helpful to have someone accompany you, listening as you walk to pinpoint the precise sources of the noise. Mark these spots with removable tape for easier reference when you start the fixing process.

Tips for Locating Floor Joists Through Carpeting

As part of fixing squeaky floors under the carpet, identifying the location of your floor joists is crucial, and here are some tips to make this task easier.

  • Use a Stud Finder: An electronic stud finder is reliable for locating floor joists. This tool can detect the denser material of the joists beneath the carpet.
  • Check for Nail Patterns: Joists are typically where the nails or screws are driven into. Look for consistent nail patterns as a clue to where joists are located.
  • Listen for Solid Sounds: When you tap on the carpet, a solid sound usually indicates the presence of a joist beneath. Hollow sounds typically mean you are in between joists.

Fixing the Squeaks

Let’s dive into the step-by-step guide that will walk you through how to fix squeaky floors under carpet. Follow these steps diligently to restore peace in your workspace.

Prepare the Carpet

Begin by isolating the area of the carpet over the marked squeak spot. Carefully pull the carpet back from the tack strip along the wall using pliers, careful not to damage the carpet.

Locate the Joist

Use your electronic stud finder to locate the nearest joist to your squeak. Floor joists are usually spaced about 16 inches apart. Once found, mark the joist location with a piece of removable tape.

Secure the Subfloor

Attach the depth control device from your carpet repair kit to your drill. This tool ensures that the breakaway screws will only drill to the necessary depth. Drive a screw into the joist through the subfloor, making sure that it is tight and secure.

Snap Off the Screw Tops

After securing the subfloor, your next step is to snap off the tops of the breakaway screws. This can be easily done by rocking them side to side until they break off, leaving a smooth, flat surface beneath your carpet.

Replace the Carpet

After all the squeaky spots have been fixed, lay the carpet back down and press it back onto the tack strips. Make sure the carpet lies flat and smooth.

By following these steps, you can effectively fix squeaky floors under your carpet and create a more peaceful and professional environment for your business.

Special Considerations

While fixing squeaky floors under carpet can be straightforward, working through carpet introduces unique challenges that demand special considerations. It’s important to approach the task with care to solve the annoying squeaks and maintain the integrity of your carpet. Let’s delve into some of these special considerations.

Working with Carpet Without Damage

To ensure your carpet remains undamaged, use pliers to gently pull it back and avoid using sharp tools that may cut or tear the fibers. When replacing the carpet, ensure it’s smooth and properly aligned with the tack strips to prevent rippling. Your careful handling will ensure the carpet’s longevity while silencing your squeaky floors.

Preserving the Untouched Look After Carpet Repair

In order to keep your carpet looking untouched post-repair, make sure to carefully realign the fibers around the repaired spot. Also, vacuum the area thoroughly to restore the carpet’s natural texture and remove any signs of work.

Preventive Measures to Avoid Future Squeaks

To ensure that your efforts in repairing any squeaky floors are long-lasting, it’s essential to adopt some preventive measures to avoid future squeaks. Let’s explore some recommendations that can help maintain the silence and professionalism of your business environment.

Advice on Maintaining Floors

Regular floor maintenance is crucial to prevent future squeaks from developing. Ensure your floors are properly installed and secured, with no loose boards or subfloor panels. Regularly check for any signs of moisture, which can lead to warping and squeaking. Lastly, consider using humidity controls in your building to minimize the expansion and contraction of the floor materials, which can lead to squeaks.

Regular Floor Inspections

Regular floor inspections, especially in high-traffic business areas, are vital in maintaining squeak-free flooring. These areas are prone to wear and tear, leading to loosening of the floorboards and subsequent squeaks. By routinely checking these areas, potential issues can be addressed early on, ensuring a professional and quiet environment for your business.

When to Call a Professional

While the DIY approach to fixing squeaky floors under carpet can be cost-effective and rewarding, there are situations when calling a professional is the best course of action. Let’s explore when you need to engage the services of a professional floor repair service.

Situations Requiring Professional Assistance

When the squeaking persists even after securing the floorboards or when there’s significant warping or damage, it might be time to call a professional. Also, if you’re dealing with an older building where the subflooring material is unknown, a professional can ensure safe and proper repairs, helping maintain the structural integrity of the floors.

Value of Professional Expertise

While the DIY approach to fixing squeaky floors under carpet can be a budget-friendly solution, it’s imperative to recognize the value of professional expertise for complex cases. Professionals bring a depth of knowledge and experience that ensures a comprehensive solution, particularly for structural issues.


Addressing the problem of squeaky floors under the carpet is essential in maintaining a professional and welcoming business environment. The presence of squeaks can be distracting and may leave an unfavorable impression on your clients. By understanding how to fix squeaky floors under the carpet and implementing regular floor maintenance, you can proactively tackle this issue, saving time and money.
