How to Fix Squeaky Floors Under Carpet: A StepbyStep Guide

How to Fix Squeaky Floors Under Carpet?

To fix squeaky floors under carpet, you don’t need to pull up the carpet.

Start by using a piece of wire coat hanger to locate the joists without damaging the carpet and mark them with tape.

If no joist is found within 16″ left or right, change direction and go perpendicular.

Then, create a small hole in the carpet without catching it using a screw.

Rotate the screw to make the hole larger and hold the sub-floor down tightly before driving the screw.

Stop driving the screw once the screw head reaches the top of the carpet.

Finally, use channel lock pliers to twist the screw until it pops off.

You will need 3″ drywall screws, tape, a drill and drill bits, a tape measure, and channel lock pliers or side cutters for this DIY solution.

Key Points:

  • Locate the joists under the carpet using a wire coat hanger and mark them with tape
  • If no joist is found within 16″ left or right, change direction and go perpendicular
  • Create a small hole in the carpet without catching it using a screw
  • Hold the sub-floor down tightly before driving the screw and stop once the screw head reaches the top of the carpet
  • Use channel lock pliers to twist the screw until it pops off
  • Gather necessary materials including drywall screws, tape, a drill, drill bits, a tape measure, and channel lock pliers or side cutters


Did You Know?

1. The term for repairing squeaky floors under carpet is called “re-bonding,” which involves injecting adhesive into the gaps between the subfloor and the joists to secure them together.
2. Surprisingly, baby powder can be an effective solution for fixing squeaky floors. Sprinkling some baby powder between the carpet and the subfloor can reduce friction and silence squeaks.
3. Squeaky floors can vary in sound intensity depending on the weather. Wood naturally expands and contracts with humidity changes, so you might notice more pronounced squeaks during high-humidity periods.
4. Did you know that squeaky floors were considered a security feature in ancient Japanese homes? The noise would alert homeowners of any intruders sneaking around at night.
5. While often associated with older houses, even brand new carpeted floors can develop squeaks due to improper installation. It’s crucial to choose experienced professionals and follow proper carpet installation procedures to avoid future squeaky floor issues.

Diy Solution For Fixing Squeaky Wood Floors Under Carpet

Squeaky wood floors can be an annoying problem, especially when they’re hidden beneath a carpet. Luckily, there’s a simple DIY solution that allows you to fix squeaky floors without the need to pull up the carpet. The main cause of floor squeaks is gaps between the sub-floor and floor joists. By reattaching the sub-floor to the framing, you can eliminate these gaps and prevent the squeaking.

Here’s how to do it:

  1. Gather the necessary tools: You’ll need a drill, screws, a screwdriver, and a stud finder.
  2. Locate the squeaky areas: Walk around the room and listen for squeaks. Use the stud finder to locate the floor joists.
  3. Mark the floor joists: Use a pencil or marker to mark the location of the floor joists so you know where to drill.
  4. Pre-drill the holes: Use a drill bit slightly smaller than the screws you’re using to pre-drill holes through the sub-floor and into the floor joists.
  5. Secure the sub-floor: Insert screws into the pre-drilled holes and tighten them using a screwdriver. Make sure to countersink the screws so they are flush with the surface of the sub-floor.
  6. Repeat for all squeaky areas: Move around the room and repeat the process for all squeaky areas, making sure to secure the sub-floor to the floor joists at each location.
  7. Test for squeaks: Walk around the room again and test for any remaining squeaks. If there are still squeaky spots, repeat the process until all squeaks are eliminated.

Note: Fixing squeaky floors may require lifting or moving furniture and may be time-consuming depending on the size of the room and the extent of the squeaks. Take your time and be patient for the best results.

Locating And Marking Floor Joists Without Damaging Carpet

Before reattaching the sub-floor, it is important to locate and mark the floor joists without causing any damage to the carpet. To accomplish this, a piece of wire coat hanger can be used. Simply straighten out the coat hanger and insert it through the carpet, feeling for the joists below. Once a joist is found, mark its location with tape. If a joist cannot be located within 16 inches on either side, it is advised to change direction and go perpendicular to find a joist.

Reattaching Sub-Floor To Framing To Eliminate Floor Squeaks

Once you’ve marked the joists, reattach the sub-floor to the framing. Start by creating small holes in the carpet without catching it. To do this, use a screw and rotate it into the carpet, gradually making the hole larger. Hold down the sub-floor tightly before driving the screw. As you drive the screw, make sure to stop once the screw head reaches the top of the carpet. This will ensure that the carpet remains undamaged.

Creating Small Holes In Carpet To Drive Screws

Creating small holes in the carpet is a crucial step in fixing squeaky floors under carpet. To create these holes, you’ll need a screw and a drill with a small drill bit.

Start by positioning the screw on the carpeted area that is above the joist you marked earlier. Use the drill to create a small hole in the carpet without catching it. Gradually enlarge the hole by rotating the screw into the carpet.

This will allow you to drive the screw later and secure the sub-floor without damaging the carpet.

Frequently Asked Questions

Do squeaky floors go away?

Squeaky floors can be a nuisance, but whether they go away or not depends on the underlying cause. In some cases, seasonal changes in temperature and humidity can cause temporary squeaks that come and go. These types of squeaks may lessen or disappear over time as the environment stabilizes. However, if the squeaks persist, it could be a sign of a more significant issue hidden beneath the surface of your floor. Properly diagnosing the cause of the squeaks and addressing it directly is crucial to ensure a long-term fix and a silent floor.

Can you silence a squeaky floor?

Yes, you can silence a squeaky floor by using a dry lubricant. If repairing the floorboards from underneath is not feasible, you can try sprinkling talcum powder, powdered graphite, or lock lubricant on the problem area. These substances help reduce friction and effectively silence smaller squeaks, even if you have limited access to the space below your flooring.

1. What are the most common causes of squeaky floors under carpet, and how can they be fixed?

The most common causes of squeaky floors under carpet are loose floorboards and inadequate subflooring. Loose floorboards can result from years of wear and tear, or they may not have been properly installed in the first place. Inadequate subflooring can occur when the subfloor is not thick enough or is made of low-quality material.

To fix squeaky floors under carpet, one option is to locate the loose floorboards by walking on the carpet and listening for creaking sounds. Once identified, screws can be inserted through the carpet into the floorboards to secure them in place. Another solution is to insert small shims between the subfloor and the floorboards to eliminate any gaps and reduce the movement that causes the squeaks. In more severe cases, it may be necessary to remove the carpet and address the subflooring directly by reinforcing it or adding an additional layer of subfloor material to strengthen the floor structure.

2. Are there any DIY methods for fixing squeaky floors under carpet, or is it better to hire a professional?

There are DIY methods for fixing squeaky floors under carpet that can be relatively effective. One option is to use powdered lubricants, such as talcum powder or baby powder, to reduce friction between the floorboards. Another method is to screw the subfloor to the floor joists, which can help stabilize the squeaky areas. However, if the squeaking persists or if the floor is in need of significant repairs, it may be better to hire a professional. They have the experience and expertise to diagnose and fix the underlying cause of the squeaking and ensure a long-lasting solution.

Overall, for minor squeaks, DIY methods can provide temporary relief. But for more extensive or persistent squeaking, it is advisable to consult a professional to address the issue thoroughly and prevent further damage to the floor.
