Replacing Joists

Postby Red T4g » Sun Jan 08, 2012 11:28 pm

Hi I was hoping that someone might be able to help.

I am currently renovating my home and have decided to move the bathroom upstairs, in doing so I lifted the floorboards to inspect the joist supporting the proposed bathroom. Upon inspection it appears as if sections of two joists have previously been replaced (with little more that a couple of pieces of unsuitable timber) and there has also been at some point a woodworm and damp problem (likely to be the initial reason for the replacements). As it was clear the substitutes would not be man enough to withstand the weights of a bathroom I set about removing the replacement sections and attempted to replace the joists. However when I tried to remove the bits of joists that had been left in the wall it became clear that the remains of the joists were the start of the neighbours! Ooops!

My question is how can I replace the joists without upsetting the neighbours and still maintain the strength and integrity needed for a bathroom. The joist have been cut flush against the wall so there is nothing I can fix against. And I'm worried about using joist hangers as the brick work is old and doesn't appear to have aged well.

Any help greatly appreciated.

Simply Build It

you can fit a transom timber, basically a timber that runs 90 degrees to the existing joists.If you planning to remove all the joists this can be bolted to the brickwork, with joist hangers attached to it and then the new joists will slot straight in.
