Hi,

Renovating a house and have noticed that the stringers on the main staircase have separated quite badly, to the point where I think it is quite dangerous - certainly can see straight through in places.

What options, other than a new staircase, do I have for repair?

Googling shows me a case where you can use threaded bar to pull the two sides together - cannot post the link but it is on the Ann Arbor website. (stair-repair-101)

What options do I have? I think the threaded bar 'hack' would work.

Thanks in advance.

Andrew

Get yourself a few more posts and you can post pictures.

Yep. I think its a 5 post min so you are almost there.

Alternately, you should be able to post links, if the photos are hosted somewhere, e.g. Imgur—but not Photobucket (a.k.a. Photosuckit).

Apologies for image orientation - not worked that out yet!

If there is wall on both sides measure the distance between the walls at the floor under the stairs in a few places so you can compare that to above the stairs.

There is a wall only at the very top of the stairs and that is not accessible.
Attached better photo.
Once I have those measurements, are you saying that threaded rod solution would be a good one to implement?

It looks like this kind of stringer with reinforcing pieces of wood missing and since open on one side, easier for the treads to pull away. Maybe original treads were replaced? Trying to pull/push the sides tighter probably would end up opening joints somewhere else or damage the stringers. I would add cleats under the stairs with glue and screws and cover the gaps with small trims. You can miter the ends then sand round for better looking ends.

It's the forum software—it's really schitty for orienting photos correctly.
