Need more details here....
has there been any revovations done before?
How much pipe would you need to replace?
Other damages? How bad is the floor, how bad is the wall?
Do you need to do any kind of mold clean up?
Is any insullation affected, will you need to update anything while you are fixing this issue?
We just had a busted pipe in our wall, currently we are at 1100 dollars and counting to replace/repair. We still have dry wall and paint to go.
With that old of a house, and no updates, you are probably looking at plaster walls, which will need to be replaced with dry wall, the pipes might be good, but if the leak was not properly cleaned up you may have issues with your subflooring and possibly the support structures if the water sat there long enough.
then theres possible mold.
At this point, I would think high and then start ticking it down. Without much more detail its hard to say.
ETA: I read that it was a basement, so here's more info...
If all you need to do is repair some pipe and redo a wall, then around 1000 would be more accurate. Other things to consider though is if there was any mold, or if the insullation needs replaced. Insullation isnt expensive, but mold clean up can be.
