How to Fix Squeaky Wood Floors?

Sep 27, 2023

While living in an old home has its charms, the squeaking sound coming from the floors certainly isn’t one. The squeaking can be due to seasonal change, or it can be something more permanent. But no matter the cause behind the squeaks, we are here to help you fix it. So read our step-by-step guide and say goodbye to annoying squeaks.

Quick Fixes For Squeaky Wood Floors

Sometimes, the wood floors squeak because they expand and contract with temperature. So before you start the DIY project, try the following hacks and see if they help with the noise.

→ Apply Powdered Graphite or Baby Powder

The solution to the squeaky floors can be as simple as applying a lubricant between the floorboards. So, identify the noisy floorboard and apply a generous amount of powdered graphite between the cracks. Brush the powder until it settles in the crack, and wipe off the excess. You can also use baby powder for the same purpose.

→ Use Wood-Safe Dry Lubricant

Another simple solution is to buy a commercial wood-safe lubricant like WD-40 and apply it to the joint between squeaky floorboards. Wear rubber gloves and work the lubricant deeper into the crack with your fingers. Wipe off the extra solution and finish off by applying a cleaner to maintain and clean the hardwood floor.

If the above hacks don’t work, gather your tools and try different methods to fix the squeaky floor.

Fix Squeaky Hardwood Floor With Shims

If you can access the floor from below, using shims is the easiest way to remove the irritating squeaky sound from your floors.

Materials You’ll Need

  • Shims
  • Adhesive glue
  • Utility Knife

1. Locate The Squeak

First, you should find the squeaking joint with a helper. Go below and ask your helper to move around. Observe and mark the area when you hear the squeaky sound.

2. Insert The Shim

After that, coat the shim in adhesive glue and insert it in the gap between the joist and the subfloor. Only slide it in until you feel slight resistance. Do the same with another shim from the opposite side. Let the glue dry, then cut the excess shim off with a utility knife.

Fix Squeaky Wood Floors Using Wood Blocks

Shims work great for smaller gaps. But if the gap is wider, or there are damaged joists, use a wood block to reinforce and strengthen them.

Materials You’ll Need

  • Wood planks
  • Utility knife
  • Measure tape
  • Adhesive glue
  • Drill
  • Self-drilling wood screws

1. Measure & Cut

Measure the distance of damage in the area where the subfloor lacks support. Then, cut the wood boards two feet longer than the damaged area.

2. Nail The Support Block

Apply adhesive glue to the front and side of the supporting block and stick firmly between the joists attached to the subfloor. Next, nail the 2 ½ inch self-drilling screws into the joists and directly into the subfloor.

Fix Squeaky Wood Floors From Above

If you can’t reach the floor from below, you need to screw through the top. You’ll need some special equipment like a breakaway screw kit containing scored screws-special screws that breakaway at the top for this method.

All The Materials You’ll Need

  • Stud finder
  • Sticky notes
  • Drill
  • Drill bits
  • Breakaway screw kit
  • Wood filler
  • Sandpaper

1. Locate The Squeaking Joist

Start by identifying the problem areas by moving around on the floor. Mark these places using sticky notes, as pencil marks can be hard to distinguish. You can also use a stud finder to detect the joist nearest to the squeaky areas.

2. Make Pilot Hole

Next, drill a hole into that joist with a drill bit slightly shorter than the scored screws. Ensure you drill into the joist to avoid hiding electric or plumbing lines.

3. Drive The Screw In

Finally, use the breakaway screw kit. Place the screw into the special tool and put the end in the pilot hole. Nail the screw using a drill until it breaks off. After removing the tool, the head and top portion of the screw will fall off, while the threaded part will hold the floor below the surface.

Next, you should fill the gap caused by the screw with similar-coloured wood filler. Lightly sand the area with sandpaper until it is smooth once again. If you don’t have wood fillers, choose a finish for your wood floor and apply that. Doing so will make the area look even and aesthetic.
