We're in the process of renovating one of our ground floor rooms and
when we
removed the ceiling we discovered one of the joists in the floor above
has
been heavily damaged over the years by woodworm (which has been recently
treated). I can wiggle the joist around and it has the consistency of
cork.
So the damage isn't woodworm, it's rot of some sort. The woodworm are
just taking advantage of the softness of the rotted wood.
Two other joists are also damaged but still seem to have strength. My
first
plan was to remove the damaged joist and install a new one but I've
realised
this is going to be difficult since one end is imbedded into the
exterior
wall and the other end imbedded into the sleeper (is that what it's
called?)
running across the fireplace hearth. Would my best bet be to run new
joists
in parallel with the existing ones using joist hangers? I've not used
joist
hangers before, is there a write-up somewhere on the Internet on how to
use
them? Thanks for any help. The link below is to some pictures of the
problem.
You need to make sure you take enough out to be sure the rot is really
removed.

Woodworm attacks start in your loft, fact. If it is Woodworm, you'll know
if you see the little burrow holes, the only remedy is to replace the whole
thing after you've treated the whole area with an appropriate solution to
rid you of the problem. Woodworm don't just sit in the wood, but do, in
adult form, sit inside the cavities of the brickwork and other little hidey
holes, and only when they mate and lay their young on the soft wood, do they
show up as burrowing little maggots. It's not the adult woodworm that
causes the problem, it's the young maggot that destroys the wood.
Have it checked out properly by Rentokil or some such company.
If it is only rot caused by dampness or fungi, then take the road of
replacing the whole of the effected area with a damp proofing timber
preserver, and make good any parts that have or are going to eventually fall
off. Do it properly now before you end up with another load of work to do
in a few months time.
