So the big Bank Holiday project was to install insulation under the floor of my Victorian terrace front room. Got all the bits for a suitable system inc wood fibre insulation, draft proof membrane for below and moisture membrane above + various tapes, primers, screws.
Managed to pull the boards up with only some damage to woodwormy bits and a few splits. Have been gluing the split ones.
Took down some newer bricks on top of the old hearth which we can now tile level with the floor.
The joists are a bit wonky ( seems to be an original feature built in.) which might be OK for reinstalling old boards but not if we want a modern floor. Trying to level them.
I contructed a duct for the air brick to channel air underneath the joists and insulation.
At every stage there seems to be some tricky problem to solve.
Someone even built a masonry wall to infill a door, on top of the floorboards! I really cant start demolishing walls now so have to work around, maintaining support.
