I have to remove a telephone extension box and cable. Removing the extension box is no problem, just unscrew it from the wall (it has already been disconected from the BT box). But I need to fill the hole drilled from the exterior of the building that the phone cable comes through. I'm going to do this myself as no doubt BT would charge a small fortune and I'm not rich!
As a novice DIYer, can anyone tell me the best inexpensive way to do this please - what filler to use etc. The filler will be exposed outside at the outer end of the hole.
Thanks for the suggestion Stua. Not sure I want to go to the trouble of mixing what sounds like concrete to me (not that I'd know really!). I'd prefer to use some king of ready mixed filler of some kind, that I can buy in a little tub or tube.
