Holes on plastered walls behind kitchen units

[tokyotecubate]

Hello all,

 

Would love to seek a bit of advice regarding to a plastered wall that will be behind some kitchen units. 

 

We are going to have our kitchen fitted on this wall as shown, where our electrican has to unfortunately make some holes to chase the wiring in. 

 

On our request, our builder has patched up some of the holes ( as you can see from the patches on the wall), but has left the holes on the wall as shown. 

 

We worry that those holes will be problematic down the line, as insects and dirt can be trapped behind - I wonder what are your views on that? Do you recommend us patching those holes around the cables? 

 

We also notice that the decorator has done a pretty bad job in filling up the holes as well - from your opinion, should we insist ( or even find another decorator) that could do a better job that this? Would this in your opinion be needed, as kitchen units re going to be fitted on this wall? 

 

We are going to be fitting this on Monday so not sure if there's much we can do about this - appreciate all your advice on this!

TBH  your lucky you even have plaster, I’ve seen some horrible things behind kitchen units. 
bare walls, half plastered, dead rats. 
once the kitchen is in surely you won’t see any of this, however I can see you point about creatures. 
talk to the electrician and get him to slide a short piece of flexible conduit over the wires, then use expanding foam to seal the hole up.

All the holes with cables emerging will surely be finished off with a back box etc.

 

That does not leave much else that cannot be filled with filler and as it won't be seen you don't need to be particular.

 

Where filler will be present and painted, you must hope your decorator finished that off properly.  There are many fillers that can be sanded so anyone should be able to fill a hole such that it cannot be seen once painted.

Thank you! if our builder is going to fill it up with sand ( as shown ), would we need to put flexible conduit over the wires? 

 

Thank you!

Ask your electrician what his plan is for terminating those cables.  I assume they are for appliances like dishwashers etc.
