I've got some questions regarding removing a subfloor. I'm thinking of removing the subfloor in my mudroom so that I can build it up for a tile floor. If I do remove, as opposed to just adding a layer on top, I'm wondering the steps needed to remove.
From the reading I've done it looks as if I need to cut the floor at the walls and add blocking at the edges so that I have a spot to nail, or screw, the new subfloor into. This blocking is where I have the questions. When I cut out the floor at the walls it seems as if I could end up, worst case, with the subfloor under the base plate overhanging the previous floor joist by about 14 inches (on the wall that runs parallel to the floor joists). How does this section of subfloor get supported? Also, I read that if the base plate is not over a floor joist, as in the case I just mentioned, when you cut the subfloor at the wall the wall might move a bit and cause cracks.
What is the procedure for doing this? I've got an unfinished basement below.
Do I attempt to find out where the cut is going to end up and put the blocking in first so that the wall is always supported?
When the blocking is added so that I have a spot to nail the new subfloor into, is 1/2 of it supposed to support the floor on the other side of this new floor (the existing floor under the base plate)?
Thanks,
Nick
