Fireplace Gap

[king 11,972]

After reading the chimmney sweep im after some info to help me sort my open fireplace out.

I ripped the old fireplace out and fitted another.

I cut the plaster surrounding the fireplace an inch bigger than the fireplace.

Screwed it to the wall and filled the gap.

But im left with big gaps and am not sure what to fill them with.

Ive been told normal cement will crack.

What would you reccomend.

Cheers king.

it is hard to tell from the pics but it almost looks like the fire surround is sticking out from the wall a bit and could do with either a bit trimming off of the back or off the wall, is there a gap at the top as well or is it flush to the wall, a photo of the whole thing may be a bit more informative, and lastly if it is fitted right and you still have that void all around it you can buy fireproof expanding foam, fill the gap and stick a bit of stainless angle over it to make it look nice, quick cheap and easy

You can buy a brass/steel trim that finishes it of .... Normally come with the surround , but not difficult to source ..

Hi GM right i ripped out an old style council fireplace and it had a load of light weight granule type filling that poured out.

The surrounding sides of the new fireplace are flush with the brickwork wall but the middle theres a good size gap it.

And above theres a big gap.

Were can i buy the trim from mate.

@chid.i bought a tub of fire cement for £5 for a little tub i would need loads of them tubs to fill the gaps.

I was hoping for a cheaper way of doing it.

Assuming that's the gap left between the fire brick that sits behind the fire and the chimney, I replaced a broken fire brick at my old place and the guy in the shop said to pour sand down behind it and down the sides so there are no air gaps left and then seal the joint at the front with fire cement.

[sussex 5,777]

Did you refill behind the fire back ? ...it should be refilled with thermiculite and parged on the top edge to allow smoke and fumes a smooth exit . The infill at the back dissipates heat to stop the fire brick cracking ..

[sussex 5,777]

Forgot ...Google fire surrounds uk and you can see what it should look like and were to get a trim ..

Are the fire bricks the 1s forming the back shape inside the fire walshie.

They are all ok.

@sussex thats all i done was removed the old fireplace and fitted the new 1

By fire back do you mean behind the fire place and the wall.its the first fire place ive ever changed and aint got much of an idea to be honest

Needs a wider fireback the old fire bricks are too narrow. And kango hammer out those blocks behind the fire bricks and the new fireback will sit flush they come in different sizes. It would have been easier replace fire back before fireplace was fitted. Vermiculite is the granule filling that goes behind fireback. Is it a 2nd hand fireplace and its missing a brass trim or liner around opening to cover the edges. Rockwool will fill any large gaps behind fire place to pack it out as long as its not too close to the heat.
