Creaking hardwood floors can be annoying, especially in the quiet of the night when every step seems to echo through the house. But what causes hardwood floors to creak, and how can you fix it? Whether it’s a minor annoyance or a sign of a bigger issue, understanding the root causes can help you find the best solution.

What Causes Hardwood Floors to Creak?

Hardwood is a natural material that expands and contracts based on moisture levels. In Reno’s arid climate, low humidity can cause wood to dry out, leading to:

1. Seasonal Expansion and Contraction

Hardwood floors naturally expand and contract due to changes in temperature and humidity. Reno’s dry climate, combined with seasonal fluctuations, can lead to wood shrinking and loosening from fasteners, resulting in creaks.

Solution:
Use a humidifier during dry months to maintain a stable moisture level.
Avoid sudden temperature changes in your home.

2. Loose Floorboards

Over time, nails or fasteners securing the hardwood planks may loosen, causing movement when stepped on.

Solution:
If individual boards are loose, use finishing nails or screws to secure them back in place.
A flooring specialist can refasten or reglue planks if the issue is widespread.

3. Subfloor Issues

Creaking may not always come from the hardwood itself—it could be the subfloor underneath. If the subfloor isn’t securely attached to the joists, it can shift when weight is applied.

Solution:
For small gaps, inject wood glue or shims between the subfloor and joists.
If the issue is widespread, you may need professional reinforcement or subfloor repair.

4. Poor Installation

If floors were installed without leaving proper expansion gaps along the walls, they may press against each other, causing friction and noise.

Solution:
If new flooring is creaking, check for adequate expansion gaps and adjust if necessary.
Professional refinishing can sometimes correct installation-related creaking.

5. Age and Wear

As floors age, nails, adhesives, and wood fibers naturally degrade, leading to creaks and pops.

Solution:
Refinishing the floors can help reset them in place.
In some cases, replacing severely worn sections may be necessary.

Quick Fixes for Creaky Hardwood Floors

1. Powdered Graphite or Talcum Powder

For minor creaks, sprinkle a small amount of graphite powder or baby powder between floorboards to lubricate the wood and reduce friction.

2. Wood Glue or Adhesive

If a board is moving excessively, use a thin layer of wood glue and press it firmly into place.

3. Tightening Floorboards

If nails have loosened, gently hammer them back in place. Use trim screws to secure planks, drilling at an angle to prevent damage.

4. Adding a Rug or Carpet Padding

If creaking is limited to high-traffic areas, placing a rug or carpet runner can help reduce movement.

When to Call a Professional
