Repair to render above front bedroom window

[fieldja18]

Hi all,

I'm looking for someone to repair the front of my house above one of our front bedroom windows. When the render was added to the front of the building I think they padded out infront of the lintel with woof fibreboard before painting over. I think a blocked drain has now caused water to soak the fibreboard causing it to crumble. I need someone to remove the fibreboard, replace with something more permenent (quick dry conrete maybe), then repaint the surface so it looks good as new. 

Can anyone help or recommend someone who can? I'd ideally have this fixed ASAP before it gets any worse. 

Thanks

James
