Hello,

We have just bought a house, and on the first day, a plank on the staircase broke because it was rotten, and my partner needed to visit the emergency room (it turned out fine, but it could have been very serious), which made me tear everything down as it looked completely rotten upon closer inspection.

We had noticed that it looked a little bad but didn't think it was in such terrible condition and planned to do something about it by summer, but now it needs to be done immediately instead.

I need help with building in a concrete stair.

Is there anything I need to consider before building it in? For example, the foundation, to protect it? Does it need to be painted like the rest of the foundation? Should a special mat or something similar be placed under the new stairs? Or is it just a matter of going ahead and building it in?

We plan to build with pressure-treated wood, the same size as it was before.

Please let me know what you think and if you have any additional tips.
 
  • Broken wooden steps outside a green house with a red broom beside them, showing decay and damage needing repair.
  • Damaged wooden staircase with rot, leading to a house entrance. Fallen leaves scattered around, with underlying concrete steps exposed.
  • Pile of broken wooden planks next to a concrete porch and stairs outside a green house, with visible damage and missing sections.
  • Concrete stairs and entryway to a house with green siding, showing wear and needing repairs. Removed wooden planks are seen to the side.
  • Close-up of a broken, rotting wooden step with rainwater drops, showing exposed, decayed wood fibers.
  • Rotted wooden steps on a staircase with peeling paint and visible damage, indicating structural issues needing repair or replacement.
  • Close-up of a deteriorating wooden staircase underside with visible rot and debris, potentially requiring repair or replacement.
Don't worry about the old stairs that are there. Build a new one on top with new stringers as the other one was. What you can do is to place an asphalt felt as a roof over it with a slight upturn towards the wall so that water doesn't run towards the house.

Can you build in such a way that it becomes easy to replace the cladding (the bottom boards) without removing the entire staircase if needed in a few years?

The paint is peeling a little on these boards where you see it looks dirty, should this be painted first before building a staircase over it? It's below freezing right now, so it will be difficult to paint..
 
You should do something about this first. No one knows what it looks like behind the panel. It is appropriate to saw/tear down the three bottom ones up to where the bridge should end. Instead of using lumber, you put a sheet that covers.

A little washing and paint, and then you'll have a great staircase, right?

Not good, there's no landing, standing 1-2 stairs down with bags and opening the door outward is not ideal.

Thought so at first too, but as jonaserik writes, it's a really dangerous staircase if you're carrying some luggage/a child and you're supposed to stand on a small step and unlock.

It's a bit tricky too, you kind of have to make the stairs against the panel.
 
This is how it looks closest to the door in the corner where the old stairs used to cover. The paint is peeling a bit, how do you think the boards look? What would you have done?
 
  • Peeling paint on wooden boards near a door corner, with visible wear and an exposed bolt.
  • Peeling paint on wooden boards near a door corner, revealing bare wood beneath. The surface appears worn and slightly weathered.
  • Peeling paint on wooden boards near a door corner, old stair location, visible wear and discoloration.
  • Peeling paint on wooden boards near a door corner, showing wear after an old staircase was removed.
No doubt they have passed the expiration date long ago. Get rid of them otherwise there will be problems in the future and put a plate. Do it right from the start.

Would personally consider demolishing the concrete staircase, especially given how it seems to affect the paneling.

Do you have any tips on what kind of sheet you are thinking of and explain a bit more on how I should do it?

Yep, it might be a bit difficult without sketching, but I'll try. Calculate how far the deck will be plus 200 mm, remove the bottom panels. After that, go to a sheet metal company and say you want sheets that are about 10 cm wider than 3 panels. It sticks under the 4th panel, and there should be a slight bend at the bottom with a fold. Place the deck on plinths, not attached to the house, except at the stairs; the stairs can also provide good support. A very simple sketch, if you right-click on it and open in a new tab, it becomes larger.
 
  • Simple sketch showing a deck structure with railing, door, panels, and a note on removing the bottom three panels for metal sheet placement under panel 4.

Put sturdy handrails on both sides of the stairs!
We old folks are many who have trouble walking if there's nothing to hold onto.
And not everyone is right-handed :D
 
Something like this a sheet if I understand correctly? Like the white sheet on the left but in a smaller format would help?
