How to fit a door threshold

Here is a step-by-step guide to fitting a brand new door threshold.

Step 1: Remove the old threshold

Remove the old threshold by cutting through any old silicone caulking.

Step 2: Cut the new threshold

  • Cut the new threshold to the correct size of the door.
  • Ensure that you choose a blade most suitable for cutting your material (aluminium and brass are softer thresholds than stainless steel ones).
  • Protect the finish of your threshold by using paper masking tape during the cutting.

Step 3: Drill the threshold

Plenty of masking tape on the threshold will help to avoid drill skid. Countersink the drill holes so that the screws will sit flush with the surface.

Step 4: Fit the threshold

Fit your new threshold either screwing it with countersunk screws, gluing with a sealant, or using a combination of the two.
