How to repair hole in dry lining

Summer2020

Had to get some Electrical work done which unfortunately necessitated some holes in the wall. How would you go about repairing this? It’s plasterboard on top of warmboard behind it. One of the holes is about 25mm x 50mm , the other 2 are very small . I assume if I just used polyfilla etc it wouldn’t be great as there’d be an area of the wall not as insulated as the rest. Any help appreciated

Is that even legal?

How do you mean?

What I know about electrical work you could write on the back of a stamp, but I thought all wiring had to to straight up or down from a socket/switch - once that has been plastered over there will be no way of knowing that there is a wire there if you decide to hang a shelf or whatever - and its only just under the plaster/over the studs.

You have to cut a small piece of plasterboard, put it into the hole and twist, allowing you to ',fix' it to the main plasterboard from the back. Then go ahead and fill hole then sand.
Just be careful if you're screwing a couple screws to hold the small bit in place , mind those cables.

Summer; How to repair holes in plasterboard is probably one of the most common things on youtube.

That said? I'm with Looksee. Wow! Who Did that?! What sort of tradesman leaves bloody great holes in ye wall and waltzes off? That's shocking. (See what I just did there ...?)

I have already searched on YouTube but thanks for the suggestion. My query was because there’s 75mm of warmboard behind the plasterboard so was simply filling the hole compromising my insulation?

I’ve had a few electricians and none of them patch up holes unfortunately. They seem a particularly messy trade.

:eek: Wow! Seriously?! I've had Two sets of sparks do work in my place ~ Leitrim ~ and Both were absolutely fastidious. The only sign that they'd been was that everything electrical was lovely.


Holes in walls? Exposed wiring? That's like me attending a rodent infestation. Dumping a cat on the floor and holding my hand out!

The holes in the wall are not really the issue here. The random cable meandering behind the plasterboard in the middle of the wall is. Wiring in walls should be in a somewhat predictable location relative to sockets, switches, lights etc.

OP that hole is way too big for polyfilla. I think you'll have to cut it to a regular shape, then create an anchor point and attach some plasterboard, then you can use filler to get a smooth finish.

It was done like that to reach a fuseboard when installing a new wired doorbell. It’s unlikely there’s ever be drilling there in future however I do take the point it’s not safe practice. I would rather it hidden than a visible cable though.

Look up Californian patch for dry wall, its a nice way to make up a patch. You can buy joint compound pre-mixed in small containers, its a great job for filling / patching.

Was done like that because he's a lazy bollix.

Is that coving at the top. Better job would be horizontal behind coving and down vertically and predictable so no one shoots a nail into it hanging a picture. Also it should be ideally sheeted in trunking

Much easier to fill with liquid foam. When its hard just scrape off enough to allow a depth of filler.

Be careful with the liquid foam over live cables...
There was a thread here a few years ago of some poor sod who was filling a cavity in his kitchen still not sure what exactly happened but the wet foam must of arced the terminals in the back of a socket or switch and blew the place asunder when it ignited the fumes from the expanding foam in the cavity. Destroyed the place . He was on Joe Duffy and all over it.
Ever since then I've always killed the power when filling around cables with exp foam

I remember that thread, but in fairness he was spraying can after can of foam into a cavity to try and fill it up - huge amounts of the stuff!

You shouldn't use expanding foam around cables anyway. It can eat through the pvc sheeting . Its not meant for that application
