Overcoming joists

[sparrrrk]

Hi all,

Hopefully some bright spark can enighten me. Been asked to move a bathroom ceiling light fitting today. Not a difficult job however I can't gain access to ceiling void due to a functional bathroom directly above the bathroom where the work needs doing. Floor tiles are laid which the customer does not want removing.

From where the fitting is now to where it needs to be a joist is in the way. Does anyone know a trick to overcome this from below. Hopefully there's a trick of the trade I haven't come accross yet.

thanks

Cut hole in ceiling.
drill hole in joist
feed cables through/extend as required.
patch hole in ceiling.

Bash hole in ceiling
extend cables with choc block
mount light fitting with plasterboard fixings
leave for plasterer to make good

seriously though no easy way. you may drop on lucky but you might not. Id start by making a hole where the new light fitting is going no bigger than what the fitting would hide. Take down the old light and then you should have a pretty good idea which way the joists and cables runs.

MF connectors surely? Daz

A choc block to me is an enclosure that you can put MF connectors in. CEF advertised them years ago after they appeared on TV as below:


Welcome to Chocbox

From their description on your link: 'A plastic box to insulate connector blocks'

I would say most people would see your phrase 'chock block' in your earlier post and assume you meant screw terminals though. Daz

Something like an Ashley box would do the job.

Mini trunking ?

Talk your customer out of the proposed move, explain the ramifications of trying to drill through a joist you can probably only see one side of, the cost of repairing the ceiling possible damage to cables or pipework on the hidden side of the joist.

find the joist that's in the way. chip out ceiling under joist, 1" hole either side, fish cable, clip to underside of joist, fix 3mm steel plate to protect cable. fill.
