uneven floorboards

[Stef]

If its only the joists that are uneven then you could go straight over it with Mapei Renovation screed as long as the floor is deflection free.

As said above an old house with sagging joists could be anything.

I would personally check that floor before i even attempted to prep it.

The Victorians (at least from aout 1870 onwards) were relatively good builders. They used copious quantities of machined timber for floors, wall plates, roofs, stud walls etc etc. they rarely built floors with dips in them. Ok there were probably cowboys even then. The implication is that the floor has sagged and is not just "uneven joists". You need to lift a cople of oards to see. It is ridiculous to offer solutions to a problem unless you know what the prolem is that you are trying to evolve. Are you just going to fish for the answer that you want in order to o ahead with the job or do you want to do it properly...... Is the client putting you under pressure??

I will get the customer to lift the boards and check it out, thanks for the info.

It's worth it mate, things like this need to be investigated, so everyone has piece of mind.
See what's going on underneath ideally after any work is done the whole floor should be replaced with 18mm ply wood.
