Why Are My Hardwood Floors Squeaking? Causes and Fixes
Squeaky hardwood floors can be frustrating—especially in quiet homes where every step makes noise. Many homeowners across Southern and Central Minnesota deal with this issue, particularly in older homes or during seasonal changes.
The good news? Most floor squeaks are fixable.
Let’s look at what causes them and how to solve the problem.
What Causes Hardwood Floors to Squeak?
Squeaks usually happen when parts of your floor move against each other. Over time, small shifts can create friction that leads to noise.
Here are the most common causes.
Subfloor Movement
Your hardwood floor sits on top of a subfloor. When the subfloor flexes under weight, it can rub against fasteners or boards, creating squeaks.
This is especially common in:
Older homes
Homes with thinner subflooring
Areas with heavy foot traffic

Seasonal Moisture Changes
Minnesota’s changing seasons play a big role in squeaky floors.
In winter, dry air causes wood to shrink. In summer, humidity makes it expand. This constant movement can loosen boards over time.

Loose Nails or Fasteners
When nails or staples loosen, boards can lift slightly and move when stepped on. This movement causes rubbing and squeaking.
This often happens in:
High-traffic hallways
Living rooms
Stair landings
Improper Installation
If floors weren’t installed correctly, squeaks may develop early.
Common installation issues include:
Inadequate subfloor prep
Incorrect fastening patterns
Skipping glue assist on wide planks
Poor acclimation

Wear and Aging
Over time, even well-installed floors can develop squeaks due to normal wear. Wood naturally dries, shifts, and settles as homes age.
This doesn’t mean your floor is failing—it just may need professional attention.
When Are Squeaky Floors Normal?
Some occasional squeaking is completely normal, especially:
During seasonal changes
In winter months
In older homes
In rarely used areas
If the noise is minor and temporary, it usually isn’t a cause for concern.
When Should You Worry About Squeaks?
Squeaks may signal bigger problems if:
The noise is getting worse
Large areas are affected
Boards feel loose
Floors bounce or flex
Cracks or gaps are appearing
These signs may indicate structural or moisture-related issues.
How to Fix Squeaky Hardwood Floors
The right repair depends on what’s causing the noise.
Here are the most common solutions.
Improve Indoor Humidity (For Seasonal Squeaks)
If squeaks appear mainly in winter:
Use a humidifier
Keep humidity between 35%–50%
Avoid extreme dryness
This often reduces movement naturally.
Refastening Loose Boards
Professionals can secure loose boards using:
Hidden fasteners
Subfloor screws
Specialized repair systems
This stops movement at the source.
Subfloor Stabilization
If the subfloor is the issue, it may need reinforcement or leveling to eliminate flex.
This is a long-term fix that prevents future problems.
Refinishing and Recoating
Sometimes squeaks are addressed during refinishing by stabilizing boards and resealing the surface.

Board Replacement
If boards are damaged or severely loose, selective replacement may be the best option.
This restores both appearance and structural integrity.
Can DIY Fixes Work?
Some homeowners try:
Baby powder
Wood shims
Screws from below
Temporary fillers
These may help short-term, but they rarely solve the root cause.
Improper DIY repairs can also damage finished floors.
For long-term results, professional repair is recommended.
