How to level a floor

Before you even think about installing new floor tiles, carpet or even laminate, let’s make the floorboards even and learn how to level a floor.

Grab a spirit level and check for any slopes. If there are any you’ll need to get flooring experts like us to level for you or if you’re feeling confident, you could have a go and try to level a floor yourself.

You’ll need:

  • Sheets of hard board
  • Panel pins
  • Nail punch
  • Hammer
  • Saw or utility knife
  • Try square
  • Straight edge

Starting from the bottom up, you’ll need to check the floor at ground level to ensure there’s an air brick opening into the room to provide some ventilation. If there’s not one, install one! Whilst you’re there you should also check for signs of mould or damp and cure before fitting the hard board.

Take up a couple of old floorboards and make a note of where any pipes and wiring are. Mark the spot on the hard board and fit slim pieces over these sections so they can be easily accessed if necessary.

Remove skirting boards to lay the new flooring underneath them. Knock any protruding nail heads below the surface with a hammer. If you have any very uneven boards you should use a power plane to level them out. Screw down any creaking or loose boards.

Cut the hard boards to size using the saw or utility knife and straight edge as a guide. Lay across the floorboards rough side up. Stagger the joints and secure with panel pins. Place a pin 100mm apart around the edge and at 150mm intervals in the middle. Ensure all nail heads are flush with the surface.

TOP TIP! Allow the new hard boards time to acclimatise to the room. Brush the sheets with a little water and leave them in the room overnight before attempting to fit them.

And there you have it; a beautiful level floor ready for your new chosen flooring.
