Skirting Boards and New Flooring: How to Plan the Right Clearances

New flooring can transform a room, but the junction between the floor and skirting needs planning before work starts. The right approach depends on your flooring system, its movement requirements and whether you are keeping or replacing the existing boards.

Start with the flooring instructions

Floating laminate and engineered wood floors usually need a perimeter expansion gap. Its size depends on the product and room, so follow the flooring manufacturer's instructions rather than using a universal measurement. Skirting can conceal the gap, but must not prevent the floor moving as intended.

Replacing the skirting at the same time

Where suitable for the chosen flooring system, removing old skirting allows the new floor to be laid with the specified perimeter clearance before replacement skirting is fitted. Check that the new board's thickness covers the gap without trapping the flooring. Fix skirting to the wall, not through the floating floor.

Check the final floor level before cutting architrave legs or ordering skirting height. Underlay and floor coverings can change the proportions of existing joinery and affect door clearance.

Keeping existing skirting

If the boards are in good condition, a suitable scotia or perimeter trim may conceal the required clearance. Choose its size after checking the flooring instructions. Where the system calls for it, attach the trim to the skirting rather than to the moving floor.

Removing boards can disturb plaster and paint, so compare the cost of making good with the appearance you want. A simple trim may be practical, while replacement skirting can produce a cleaner visual line.

Carpet and tiled floors

Carpet fitters may need an appropriate space at the perimeter for their fitting method. Agree the sequence and clearance with the fitter before installing boards. Tiled floors have different joint and movement requirements: ask the tiler how perimeter joints will be detailed rather than filling every junction rigidly.

Check doorways and awkward corners

Measure thresholds, door openings and changes between rooms. Check that doors can operate above the finished flooring and that any alteration to a fire door is permitted by its specification. Do not trim a door without checking its construction and allowable trimming limits.

A simple planning checklist

  • Confirm the flooring type and manufacturer's expansion requirements.
  • Measure the final floor build-up, including underlay.
  • Decide whether to keep or replace skirting.
  • Check that the chosen profile will conceal the intended gap.
  • Agree the fitting order with your flooring installer.
