This way it is out of sight and out of mind,but a new extension or the bedroom with a teenager wanting TV wasn't planned back then.
So how does the cable get to the relevant tv point.
Well if it is an upstairs room,it can from the loft and into the room,and be laid in trunking nice neat way of doing it.
Downstairs this isn't an option,so the most sensible way is through a wall or through a window frame if the frames are wooden that is.With most windows being PVC these days that isnt an option.
Through the wall is the easiest and quickest way to gain entry for a cable,but it does come with a lot of buts.The old hammer drills were slow and very good at knowing the front of a brick off,however drilling a 12mm hole in even average bricks is patience testing.
In comes the much more powerful SDS drill,brilliant.Now the prblem is knocking the front of a brick off which looks a complete and utter mess.The key is to slow right down and not go hell for leather.
This trick doesn't always work so sometimes a cover plate will neaten things up
