I have a large crack above my front door, see pic. I want to repair it before decorating my hall but not sure how to go about it. I could easily fill the crack with filler but i know it wont last so what I want to do is to knock the plaster all off and start again. Any ideas as to how I should go about it would be most helpful. Thanks in advance.

The pic is located in my profile, not sure how to post it on the main page.

It extends the width of the door and its hollow underneath thats why I thought it was a waste of time to try and just fill the crack.
Just looking at the picture what I believe has happened is the crack has opened up due to shrinkage of the plaster on the lintel & the lump of plaster below the crack has delaminated; if it’s an older property its likely to be concrete. If there was a crack in the blockwork or a crack in the mortar joint below, it will always return unless it’s sorted out properly but it looks to be directly over the lintel (assuming it’s got one!) & not where the lintel meets the brickwork. If so, the crack will only be plaster deep & providing the lump of plaster is not actually loose, you could try raking out a fairly deep “V” groove along the crack & filling with a flexible polyester filler; it may work or at least you could try it first. The only other alternative is to remove the plaster completely, apply a new base coat & then reskim to blend in locally but if you’ve not done this sort of thing before, it may be too much for you; it will be difficult to get a decent finish let alone an invisible repair.
Thanks for your reply, think I will try to do it the second way.
I would agree with what Rich'd says and remove the loose plaster from the lintel area. Once the blown/loose plaster has been removed and the area prepared/PVA'd, I would bed on, across the lintel (with dabs of multi finish) a length of "Expamet" corner bead, flush with the surrounding plaster level,and when the dabs have set, plaster over the lintel area with bonding plaster and multi.
