I have a second floor dormer/room that had dropped a few inches on one end

needs to go up about 4 inches in order for the dormer/room floor to become

cracks etc., but I am redoing the house so that is not an issue or problem..

My question is, what can I put on top of the bottle jacks to spread the load
out over a larger surface area. *I assume I can look for and buy a couple of
small steel plates to put on top of each bottle jack, but I am not sure.
Or, is there something that is made for this that is available?

Thanks.

A screw jack is cheap and will help with control, you want to do it
over weeks or more.
