We're renovating a very dated 1970s house and removed an artificial beam (it was wood on all sides and hollow in the middle) which revealed a big straight crack in the ceiling. The crack itself isn't that wide but one side of it has dropped by 3-5mm. This seems to have cracked the plaster on the walls at either end of the ceiling crack, on one side (outer wall) a zig zag crack goes right down to the floor and on the other side (inner wall) it's a straight crack about 15cm along the corner where the ceiling meets the wall.
The position of it is we have a L shaped lounge diner and this artificial beam was between the lounge and the dining room - we intend to put in double doors/similar.
When the house was surveyed it wasn't visible as the crack was behing the wooden beam and wall cracks were behing wall paper and a stone cladded wall.
Do I need professional opinion on it or just a plasterer or decorator to cover it up? Might it get worse? I don't want it to buckle the interior doors we intend to put in.
