Stair stringers

[Swwils]

I currently have the following in my new build.

Is there anything I can do to improve the transition to skirt?

Know nothing about stairs. Not quite sure why the sides are so far from the wall.

You could maybe remove that quadrant strip profile, which they have put on to disguise it and have a special profile made up by a specialist to replace it.

Is it fine for me to cut into the stringer?

I have the right ogee router bits to match the skirt so could rustle something up.

It's just occured to me this offset is why you can't get your hand down the rail on the next flight since the wall is too close to the rail!

I would be very wary of weakening the stringer.

I'm hoping that it's a full string and cut string construction.

I will check (it's accessible underneath through storage) and work a way forward.

Thanks for your info!

I'm hoping that it's a full string and cut string construction.

If there is a wall on both sides of the stairs there will be a full stringer on both sides. If one side or the stairs is open and the stringers are like those in the picture below:-

Then you have a mixed construction, one side cut, the other full, sometimes called a half cut stringer stair. Most commonly, though, stairs in the UK have full stringer construction simply because it is a lot faster, easier and cheaper to make. It is also potentially somewhat stronger

Either way you shouldn't modify the full stringer by cutting material away because both the treads and risers are held in place by glue and wedges at the back. Any substantial amount of cutting away the stringer can weaken the stringer and/or displace the wedges. Just don't do it!

The way to deal with this is often to form a moulding during manufacturing on the top of the stringer which matches the skirting moulding. The extra thickness of the stringer over skirting (often 28 to 38mm vs. 18 to 25mm of skirtings) is sometimes hidden by installing the stairs prior to installing the MF studwork and its' plasterboard on top of the stringer, thus reducing the visible thickness. This sort of detail needs to be in the original design, though, and is difficult to achieve after the stairs are installed

If I may? Do you like that skirting?
It's an horrible detail, can you:
1/ not get them to snag it and point out the dodgy beading and the detail?
2/ change the skirting to something more appropriately sized, height wise?
So that it runs into the stair stringer.
3/ Take that manky beading of and cut the skirting at 45 degrees that top corner.

 

[Swwils]

Lets just say its the least of my worries and I am year down the "snagging" pipe. But I appreciate the input.

I don't mind the skirting, we have young kids.

I just wondered what the usual stringer detail was and how far off the mark it is!

Fundamentally it is like a lot of detail in new builds - not well thought out and poorly executed
