What is this called? Old style window. Pic included!

Please help! What is this part called on old windows? I need mine totally replaced but can't find someone with the right expertise until I have the first clue what I'm asking for.

Lintel?

Either a lintel or a decorative stone head I think?

If it’s made of stone then I guess you need a stone mason.

Thanks. Sorry should have specified, the one on my house is made of wood.

Had a Google n looks like it's an external dentil cornice

If the corbels are wood have a look at this company, richardburbidge.com/shop/mouldings

They have all sorts of mouldings and it might be possible to create something similar. You would still need a good, sympathetic carpenter to construct it.

Thanks so much everyone

It's just a plaster cornice, but I can't see clearly what It's purpose is. It looks like it covers up the timber structure that holds up your bay window roof and possibly a parapet gutter. So you might need a roofer for lead flashing and a lime plasterer/general builder/carpenter for the timber repairs behind the cornice and then replastering.

What is wrong with it? Why does it need to be replaced? Is it leaking?

I mean the cornice is just decorative and usually can be taken off to carry out any structural repairs behind it. If it is wood, a joiner will be able to repair any rotten bits (cutting bits out and splicing new bits in), if it is plaster, a plasterer can refix it.

Yes it's rotten wood that's the issue. Thank you.

If it is just rotten wood on the decorative cornice bit, then what you need to look for is a Window Joiner. But if it is severely rotten (doesn'tlook bad in the photo though), there might have been some water leaks (damaged/blocked guttering or faulty flashing) causing it, so you might have a builder/roofer check for any water ingress behind/onto the cornice.

@NellyBarney thanks so much for your help. Sorry, I realise I wasn't clear, that's not actually my house. That's just a picture from Google of something similar, I wasn't at home when I posted. Mine isn't in very good condition.

Know a lot more about what I'm asking for now though, thanks all.
