How to replace skirting board running up a stair case

[bwaj]

Replacing plain old horizontal skirting board seems to be a pretty simple job, but what about when it runs up a staircase?

Below are pics of what we have and want to replace. I don't know how it was cut/installed or how we can go about removing and replacing it (without damaging the stairs). Would welcome any advice.

Looks like you have a moulding on top of the stringer. The moulding should be removable, but if it's glued on then it may have to be cut off.

It could be ripped down skirting as opposed to a standard moulding. In which case you could do the same again.

It might well be moulded onto the top of the stringer (i.e eith a router). Normally I'd expect somewhat more "meat" above tread than there is above this example. If it is moulded in place do not attempt to remove it - you will weaken the stairs

Simple answer - you don't (and there isn't)

Basically, in laymans terms, you do not have a skirting board running up the sides of your stairs.
What you can see are the side supports, (stringers, as JobAndKnock stated), and the treads and risers are slotted into both sides.
Unfortunately you can't replace them, (no matter how plain they may be), without actually having a new staircase installed, (which is a specialist job not suitable for a novice). Also likely to be quite expensive.

Many thanks @TimboTwo @JobAndKnock @^woody^ @conny for enlightening me.

We definitely don't want to install a new staircase. But we do want to replace the skirting boards you see running along the floor horizontally at the bottom of the stairs. So the question becomes: how do we keep the style of the new skirting board and side supports/stringers consistent?

Per your advice, I will investigate whether we can remove and replace the moulding on top of the stringer with ripped down new skirting. @JobAndKnock what do you mean by a 'router'?

You try to match the profile of your new skirting to that of the original. It may require a plinth block to be installed at thr bottom of the stairs between the skirting and the stringer to allow this. You won't be helped by the fact that your stringers should have been cut to length at the bottom to allow a taller skirting to marry to them (i.e. the vertical end cut is wrong). Trying to trim the end in situ now without making a hash of it is quite difficult

@JobAndKnock what do you mean by a 'router'?

Used to drive a cutter which cuts a profile into a piece of timber
