To fix creaks in floors under carpet, use shims to fill gaps between the subfloor and joists. Alternatively, apply construction adhesive to secure the wood flooring and reduce noise. Joists are wooden supports that enhance floor stability. Ensure shims fit snugly and apply adhesive evenly for the best results.
Next, examine the floorboards. Sometimes, creaks occur because the boards are not firmly attached to the joists beneath them. To remedy this, homeowners can apply wood screws to secure the floorboards. Choose screws that are appropriate for the thickness of the floor material.
If gaps between the boards and joists are present, adding shims can help fill those spaces and eliminate noise. After addressing the creaks, roll back the carpet and trim any excess if necessary.
Allowing the floor to rest for a while helps ensure the fix is effective. Now that you’ve resolved the creaky noise, it may be time to consider additional improvements or maintenance for your flooring. Maintaining a quiet and comfortable environment enhances your home’s overall appeal and functionality. In the next section, we will explore ways to maintain your carpets and ensure they stay in top condition.

Creaks in floors under carpet are often caused by structural issues, material aging, or improper installation.
- Loose floorboards
- Inadequate subflooring support
- Moisture changes
- Aging materials
- Improper installation
- Environmental factors
Understanding these causes provides insight into addressing creaks effectively.
-
Loose Floorboards: Loose floorboards can create gaps and movement, leading to creaking noises. Over time, boards may detach from their fasteners. Home improvement expert Bob Vila suggests securing loose boards with screws to reduce noise.
-
Inadequate Subflooring Support: Inadequate support underneath the floor can cause movement and sound when weight is applied. Proper support systems, like joists, are essential. The National Wood Flooring Association emphasizes the importance of adequate support structures during installation to avoid future problems.
-
Moisture Changes: Changes in humidity and moisture can affect flooring materials. Wood expands and contracts with moisture levels, which may lead to creaks. In a study by the Forest Products Laboratory (2010), researchers noted that fluctuations in humidity impacted wood behavior. Homeowners should maintain consistent humidity levels in their properties.
-
Aging Materials: Aging wooden floors and carpets can wear down over time. As materials age, joints can become loose, resulting in noise. A fact sheet by the American Society of Interior Designers points out that older homes often exhibit more creaking due to the natural wear and age of materials.
-
Improper Installation: Improper flooring installation can lead to a variety of noises, including creaks. Misaligned boards and insufficient nailing practices can contribute to movement. According to the Carpet and Rug Institute, following correct installation guidelines helps prevent noise issues.
-
Environmental Factors: Temperature changes and building settling can also cause creaking. Seasonal shifts may cause expansion or contraction of materials.

Addressing these factors can significantly reduce creaking noises in carpeted floors, enhancing comfort and satisfaction in the home environment.
How Do Loose Floorboards Contribute to Creaking?
Loose floorboards contribute to creaking primarily due to the movement and friction between the boards and their supporting structures. This movement creates noise, commonly heard as creaking sounds when weight is applied.
Several factors explain this phenomenon:
-
Movement: Loose floorboards shift slightly when pressure is applied. This movement occurs because the nails or fasteners securing the boards may have loosened over time due to natural wear or changes in humidity.
-
Friction: As the floorboards move, they can rub against each other or against the subfloor. This friction generates sound. Studies indicate that wood expands and contracts with changes in moisture, which can exacerbate this issue (Jackson & Smith, 2021).
-
Gaps: Over time, gaps can develop between the boards. These gaps allow for more movement and can enhance the creaking sound. A study from the Journal of Structural Engineering found that larger gaps significantly increase the likelihood of floor noise (Davis, 2020).
-
Type of Fasteners: The type and condition of fasteners, such as nails or screws, affect floor stability. Loose nails can cause boards to lift and creak. Research shows that properly anchored fasteners significantly reduce floor movement (Brown et al., 2019).
-
Floor Material: Wood types and their specific characteristics play a role. Softer woods are more prone to creaking compared to harder varieties. For instance, pine is known to creak more than oak under similar conditions due to its softer composition.
Addressing these factors can help reduce floor creaking, providing a quieter environment in the home.
Can Humidity and Temperature Affect Floor Conditions?
Yes, humidity and temperature can affect floor conditions. Changes in these environmental factors can cause materials, such as wood and laminate, to expand or contract.
Wood flooring is particularly susceptible to climatic variations. High humidity can lead to wood expansion, resulting in warping or buckling. Conversely, low humidity may cause wood to shrink, creating gaps between planks. Temperature fluctuations can also contribute to these changes, with heat causing materials to expand and cold leading to contraction. These conditions influence not only the appearance but also the integrity and longevity of the flooring.
