Our London handymen have mastered the hanging of LCD screens to any wall, plasterboard, masonry or chimney breast. But we get loads of requests to conceal the TV and accessory cables behind the wall. But this part of the job is far more complicated and time consuming than customers often realise.
Plasterboard is put up on vertical timber or metal studs, which block the horizontal route for cables behind the plasterboard. This means the only simple route to follow is vertically between two studs. The most common installation on plasterboard involves cutting a 80mm hole behind the screen and a second hole just above the skirting board. The cables are pushed through the hole behind the screen and exit above the skirting board. They are then routed to the plug socket and accessory along the skirting board.
On disused chimney breasts we cut a 80mm hole into the brickwork behind the screen and an exit hole on the side of the chimney breast where the accessories and power point are. The cables are then pulled through the cavity in the chimney breast and exit on one or the other side.
With solid masonry walls however, the process is allot more time consuming and messy. A channel has to be cut and chiseled into the masonry following the route the cables need to take. A trunking is fitted in the channel and the cables inserted into the trunking. The channel is then filled over and the filler allowed to dry for 24 hours. It is then sanded smooth and painted over. It is essential to ensure that the paint used is an exact match to the original paint.
