Squeaky hardwood floors don't have to be a permanent fixture in your home. With a few easy techniques, you can silence those pesky noises and enjoy the tranquility you deserve.
In this blog post, I will walk you through the steps to identify the cause of your floor squeaks and provide step-by-step solutions so you can fix the problem yourself.
Key Takeaways:
- Squeaky floors happen when wood components rub together – it's usually fixable!
- Causes include humidity changes, loose subfloors, and improper installation.
- Try lubrication as a quick fix, or shimming and screwing for longer-lasting repairs.
- Control humidity levels to prevent future squeaks.

What Causes Squeaky Hardwood Floors?
Before we dive into fixing your squeaky hardwood floor, it's important to understand what's causing the problem. The primary culprit behind those annoying sounds is friction.
Here's a breakdown of the most common reasons why your floorboards might be rubbing against each other or their supports:
- Expansion and Contraction: Hardwood naturally expands with increased humidity and contracts when the air gets drier. These seasonal shifts in size can cause gaps or loosen floorboards, leading to squeaks as you walk.
- Loose Subfloor: The subfloor is the layer of support beneath your finished hardwood. Over time, the subfloor may develop gaps or become loose from the floor joists below. This creates space for your hardwood floor to move and rub, resulting in squeaks.
- Warping: Due to moisture changes or age, individual floorboards may bend or warp slightly. This warping can cause areas of friction and squeaking when weight is applied.
- Improper Installation: If your hardwood floor wasn't installed correctly, nails or screws might not be properly secured. This loose fastening again allows individual boards or sections of flooring to move and squeak.
Top Methods to Fix a Squeaky Hardwood Floor
Now that you understand why your floor is squeaking, let's get to the good stuff – fixing it! Here are the most effective methods, ranging from the quickest fix to more involved solutions:
Method 1: Lubrication (Quickest & Easiest)
Materials:
- Baby powder, powdered graphite, or talcum powder.
- A method for application:
- Squeeze bottle (like an old hair-dye bottle)
- Paintbrush
- Old sock or cloth
How it works: Lubrication reduces friction between the wood surfaces that are rubbing and causing the squeak. While it may offer a temporary fix, it's the quickest way to try silencing a squeak.
Steps:
- Identify the squeak: Walk on the floor and pinpoint the exact source of the squeak. If you can, mark the spot.
- Clean the area: Sweep away any dust or debris in the gaps between the squeaky floorboards.
- Choose your application method:
- Squeeze bottle: Great for precision. Fill with your chosen powder and gently squirt into the cracks between boards.
- Paintbrush: Dip in powder and gently brush it into cracks.
- Old sock or cloth: Load it with powder and rub across the squeaky area.
- Work it in: Walk over the area to work the lubricant deeper between the floorboards.
- Clean up: Wipe away any excess powder.
Important Notes:
- Reapplication: Lubrication might need to be reapplied periodically, especially with changes in humidity.
- Graphite: A less messy option, but leaves a slight gray residue. Choose baby powder or talc for a cleaner finish.
Method 2: Shimming from Below (For Access to Floor Joists)
Materials:
- Wood shims (tapered wedges of wood, found at hardware stores)
- Carpenter's glue
- Hammer
- Safety glasses (to protect against wood splinters)
Best for: Squeaks you can easily locate, with access to the underside of the floor (basement or crawlspace). This method is less invasive than screwing from above.
Steps:
- Safety First: Wear safety glasses.
- Locate the squeak: Have someone walk over the squeaky area while you listen from below. Mark the spot directly above the squeak on the subfloor.
- Apply glue to shim: Coat one side of a wood shim with a thin layer of carpenter's glue.
- Insert the shim: Gently tap the shim into the gap between the floor joist and subfloor with a hammer. Aim for a snug fit, but avoid driving it in too far, as this could lift the floorboard and cause unevenness.
- Trim excess: If needed, break off or score and snap the excess shim so it doesn't interfere with anything below.
Important Notes:
- Multiple shims: You may need to use multiple shims to cover wider gaps and fully stabilize the area.
- Shimming vs. Construction Adhesive: Shimming is a good first option, but for particularly stubborn or large gaps, applying construction adhesive between the joist and subfloor, then adding a shim for support, may be a more robust solution.
Method 3: Securing from Above (When Subfloor Access is Limited)
Materials:
- Screws (appropriate length for your flooring thickness and subfloor - generally 2-2.5 inches)
- Drill with a drill bit slightly smaller than your screw diameter
- Screwdriver or drill with screwdriver bit
- Stud finder (to locate floor joists)
- Wood filler (optional, to conceal screw heads)
- Stain or paint to match (if using wood filler)
Best for: When you can't access the underside of the floor to shim and want to minimize visible repairs to the finished floor surface.
Steps:
- Locate Joists: Use a stud finder to find the floor joists below the squeak. You may also see nail patterns on your floor, indicating where the boards are secured to the joists.
- Drill Pilot Holes: Drill pilot holes at opposing angles through the squeaky floorboard. The opposing angles help pull the board tightly against the joist. Make sure your holes line up with the center of a floor joist.
- Carefully Drive Screws: Slowly drive your screws into the pilot holes. Stop just before the screw heads are flush with the floor surface to avoid dimpling the wood.
- (Optional) Conceal Screw Heads: If desired, fill the screw head recesses with wood filler. Once dry, sand flush, and touch up with stain or paint to match your floor.
Important Notes:
- Screw Length: Choosing the correct screw length is crucial. Too long, and they'll go through the subfloor and be visible from below. Too short, and they won't provide enough hold. Use a tape measure on the edge of your flooring to determine the total thickness.
- Counter-Snap Screws: Special "counter-snap" screws designed for floor repairs are available. They have a break-away point below the head, allowing you to drive them fully and then snap off the top, leaving a clean surface with no head to fill.
Preventing Future Squeaks
Fixing an existing squeak is great, but wouldn't it be even better to avoid them in the first place? Here are some key tips to help prevent squeaky hardwood floors from developing:
Humidity Control
Hardwood is sensitive to humidity fluctuations. Maintain a consistent indoor humidity level, ideally between 35-55%. Use a humidifier in dry winter months and a dehumidifier in humid summers. This will minimize the seasonal expansion and contraction that can create squeaks.
Proper Installation
While DIY is increasingly popular, improper installation can set the stage for future squeaks. If laying new hardwood floors, consider hiring a professional installer. They'll ensure proper fastening to the subfloor and account for necessary expansion gaps along walls and fixtures.
Acclimation
If you're installing hardwood yourself, allow new wood flooring to acclimate to the humidity of your home for a few days before installation. Spread the boards in the area where they'll be installed. This helps them adjust to the environment and minimizes movement after they're laid.
Even with careful preventative measures, some degree of squeaking may still occur over time as your house settles and materials naturally age.
