Fixing Squeaky Floorboards
That persistent squeak with every step can be more than just a minor annoyance; it can disrupt sleep and peace. Whether it’s a teenager sneaking in past curfew or a late-night trip to the kitchen, squeaky floorboards are a common issue in many homes. Understanding the cause and implementing the right fix can bring quiet back to your home.
Understanding Squeaky Floors
- Cause: Floor squeaks are primarily caused by the natural expansion and contraction of wood due to changes in humidity and moisture levels. This process leads to the following issues:
- Wood Shrinkage: As wood dries, it shrinks, creating gaps between the floorboards and the underlying structure.
- Loose Fasteners: Nails or screws holding the floorboards in place can loosen over time due to the wood’s movement.
- Rubbing: When someone steps on the floor, the wood moves and rubs against these loosened fasteners or other adjacent surfaces, resulting in that irritating squeak.
Repair Options
- Sistering Joists (Working from Below):
- Add Framing Strips: Attach strips of framing wood to the existing joist.
- Secure with Adhesive and Screws: Use construction adhesive and screws to secure the strip to the joist and the subfloor.
- Key to Success: Construction adhesive is essential as it bonds to all surfaces and doesn’t shrink as it cures.
- Adding Shims (Working from Below):
- Insert Shims: Add thin wood shims to gaps between the floor joists and the subfloor.
- Use Adhesive: Apply construction adhesive to the shims before inserting them.
- Gently Tap: Gently tap the shims into the gap. Avoid pounding, which can widen the gap and worsen the squeak.
Summary: Squeaky Floorboards and How to Fix
Squeaky floorboards are caused by wood shrinkage and loose fasteners. You can fix them by adding framing strips to the joists or inserting shims into the gaps, using construction adhesive for a secure and lasting repair. Working from below, secure the strips or shims gently to avoid further damage.
