Best way to repair crack.

Hi
The house we're moving into has a crack running from the window fram to the skirting in one of the bedrooms:-

The surveyor checked it out and said it was cosmetic and there is no corresponding crack on the outside of the property.
I want to avoid reskimming this particular room as there is no other damage. Could someone recommend the best way to do a neat job of repairing this?
Thanks,
Steve

Chip off all loose plaster, don't worry if you're left with a big canyon.
Buy some cellulose filler, like this: http://www.screwfix.com/app/sfd/cat/pro.jsp?idb292&ts 850
And a filling knife, like this: http://www.screwfix.com/app/sfd/cat/pro.jsp?idb907&ts 879
And some sand paper: http://www.screwfix.com/app/sfd/cat/pro.jsp?idC908&ts 931
And a sanding block: http://www.screwfix.com/app/sfd/cat/pro.jsp?id 104&ts957
Having cleaned the crack, mix up some filler (instructions on box) and apply to crack, making sure the filler surface is a little below the finished wall surface. Wait for this to set.
Mix up a second lot of filler, and use it to finish off the crack slightly proud of the wall surface. Leave to set overnight.
Sand until it is smooth and level with the wall.
Paint.

That isn't a plaster crack, it's in the brickwork, something below this window has moved in the past or is still moving, has there been any widening of doors or other structural work carried out below it?

Hi
Its above some patio doors leading to the conservatory. The external brickwork looks fine. Do you reckon I should hack the plaster right off and look behind then?

That would be your best policy. I like Phillip had doubts whether it was just a crack appearing and since you have confirmed there's patio doors been put in down stairs below it makes you wonder.

With respect, given your limited knowledge it is extremely unlikely you would be able to assess the wall meaningfully.
Hacking back the plaster will simply show you a crack in the brick/block wall. There must be one, otherwise the plaster would not have cracked. But what would that tell you?
House walls crack - that's life. It's all part of the natural settlement process. The real question is whether there is a crack that is growing, or has been caused by recent work.
You initially stated that you'd had a surveyor look at the wall. I took this to mean that it had been inspected and passed. If you are uncertain about his, get a structural engineer in to advise you.

Hi
Yes, the surveyor said he didn't feel it was anything to worry about.

That wouldn't be of much use because we already know that the brickwork is also cracked. What I think has happened is that whoever knocked out for your french doors has not put a lintel in on the inside skin, this would explain why there is no corresponding crack in the outside wall, he may not have put a lintel on the outside skin neither but the patio door frame would go some way to holding this up, either way, you are going to have to check for a lintel above this door...it /should/ be steel but could be concrete or even timber. The safest way to check is to chip the plaster off....I'll do a quick diagram of where you should look - *don't* start banging holes out of it in the middle!

Hi
There is definitely a concrete lintel on the outside skin. I'll check for a lintel on the inside skin at the weekend.
Thanks for your assistance.
