Hello.

We have a wooden deck (walk out from 2nd floor) and wooden stairs down
onto our backyard.

We had it installed about 13 years ago and on one corner of the bottom
of the stairs, brick that supports deck stairs is a bit broken and
that corner is lowered down onto the ground.

(I think the reason was gradually gravity forced this corner down as
that part of soil was maybe weaker than other parts of our yard but I
am just guessing)

In terms of how far this corner went below the ground, I would say
around 3~5 cm compare to other corner of the stairs.

Originally, I was gonna call the deck/renovation specialist to fix the
problem but now I am thinking about doing it myself if possible.

I am thinking of renting 'Jacks' from home depot and raise that
corner, fill up the soil little, replace the brick that's broken,
lower the deck back down onto new brick.

To those experts, would my trial be enough or am I just wasting time?
I would appreciate any feedback.

Thanks.
