When it comes to fixing skirting boards internal joints scribing is by far the most common practice. Even if at first thought it may feel like uncharted territory, even to the most hands on DIY enthusiast. Us at Skirting Supermarket are here to assure you otherwise providing you have the correct tools and a pinch of patience.

We are here to make the process of how to scribe skirting boards from 90° internal to the most common odd angles that can be found in houses and offices across the country as easy as possible.

This is the reason we use a scribble joint when fitting skirting boards. If there is any slight difference in the angle which makes it not 90° than a mitre joint will not fit together correctly leaving a big gap in the skirting board joint.

So let’s get started

The tools you will need are…

  • Sharp pencil
  • Fine tooth saw
  • Combination square
  • Coping saw


Firstly let’s have a look at what scribing skirting boards actually is.

Scribing is the technique in woodworking of shaping the end of a skirting board profile to perfectly fit the contours of an abutting skirting board.

Internal joints. The majority of internal corners will be of 90° or greater for example under bay windows which are generally 122.5°.

Firstly we need to get the shape of the skirting board which we need to cut out. To do this we need to cut the skirting board at a 45° angle down the face at the end of the skirting board. Highlight the skirting board profile by running a pencil down the front edge aris. For the straight cuts we need to us a saw which is designed to cut straight lines which in this case is a fine tooth saw. You want to try and avoid cutting straight down but more of a back cut so that when the 2 skirting boards meet it is only the front edge that will be touching. Proceed to cut the skirting board only to where the profile begins.

Now it’s time to switch to the coping saw which is designed to cut curves and angles. Starting at the top of the skirting board profile (which needs cutting square as this will be visible once the 2 lengths of skirting boards are fitted in position). The remaining profile needs to be slightly back cut again so it is only the front edge that will be touching once fitted.

Always keep the coping saw moving because if you stop and try twisting the blade it will most probably snap.

It’s now time to see how you did and check the 2 skirting boards join correctly, which if this guide has been followed should be the case.
