Squeaking staircase !

[Tobbe Mieden]

Hello everyone

We have a Smålandsvilla model Kalmar with a wooden staircase as shown in the picture below, where most of the steps are starting to creak and make noise.
It practically echoes in the house when you walk on the stairs.

We have now tried to hammer wooden wedges between the stringer and the carriage with the help of a jack without much success.
We have tried to put support blocks under the steps without much success.

So my question is, does anyone have any tips?
Is it time to dismantle the staircase and reinstall it?

Grateful for help

A photo of the entire staircase is good.

Yep, an L-shaped staircase, it's not unusual for one to creak.. It hangs on the outer stringer, which doesn't have support and is hanging in the air. It needs support from the floor up, holding the bend in the curve. To install one, it must be pushed up into the bend and the post attached from below. I have an L-shaped staircase myself, but installed an extra post in the bend, but did it from the beginning. I can walk on it, not even the cat reacts.

It needs support from the floor up that holds at the bend of the turn. To put one there, it must be pushed up into the bend and secure the post from below. I also have an L-staircase, but added an extra post at the bend, but did it from the start. Can walk on it, not even the cat reacts.

There it is!

Took the jack and lifted at the outer corner and 95% of the creak disappeared! Thanks for the tip!

It is a bit short in the first part, the upper part is long, so a post that is notched and placed on the vagnstycket about 20 cm up from the fold and rests on the klacken and attached on the outside of the vagnstycket will be good for you. A 45 X 95 is sufficient to withstand downwards pressure.

We tested sitting like this; however, the upper steps still creak. The rule is screwed into the outer stringer after we lifted the stairs with the jack.

Yep, and that's because the staircase has twisted and the steps are now slightly askew in the fitting. How is the stringer by the wall, is it anchored to the wall or hanging loose? I also put a support in the inner corner. You should try it, as you can see you've only temporarily placed a support as a test under one step, so it might creak, but it's good to test first. It's said that they're supposed to be self-supporting, but they sure aren't.

Check the assembly instructions for the staircase. Probably, the steps and the fittings in the stringers should be lubricated with paraffin, something that probably hasn't been done. To make it right, it's "just" a matter of disassembling the staircase and addressing it, then reassembling it.
