Re: Sistering floor joists
This can be easily done by placing the new joist up against the floor above and placing shims under these joists where they rest on the wall plates.
So is it more important that the bottom edge rests even on the top plate with the old joist, or that that top edges are level against the floor up above.
Notching for plumbing always makes me shudder.
in a couple of places there is a bit of notching near the top that has to happen to help accommodate the tub drain.
There are specific guidelines regarding notching floor joists and it's critical this is done properly.
If at all possible consider routing the plumbing in another direction to avoid notching.
This may depend on how easy it would be to get the new joist in place after the plumbing is done ..... it might be simpler to install them before hand.
Should we get these new joists attached before or after the plumber replaces all the old pipe?
Hope this helps.
