Leaky fireplace Eldfast/Thermocrete

[silurian]

Hi, I have an open fire which I 'Used to' burn coal/wood on.

Unfortunately, I have had to stop using it as my daughters bedroom (directly above the room the fire is in) has filled with smokey fumes the last couple of times we used it.

I understand that a metal flue needs to be minimum 8" and would be almost impossible to install given the age of the property (1917).

One solution I have come across is using Eldfast/Thermocrete systems but they are going to cost £2000/£2500 just for one chimney flue! Does anyone have any bright ideas/alternative solutions, as I really would like to be a little warmer this winter!?

Many thanks

Hi.

Some years ago I installed a "vermiculite / cement" slurry like weak concrete into several Ex-MoD properties.

The process was to install a neoprene circular former down the chimney, blow it up then from ground level pump this mix into the space between the former and the internal surfaces of the chimney.

Once firm the former was deflated and withdrawn.

This link may assist?

If not I can e-mail; this document you need section F in it.

THanks KenGMac.

THat is the thermocrete system you are describing and the cost is about £2500 for my flue! Maybe more cost effective if someones having my than one chimney repaired in the stack though.

Since reading your post, I think I might opt for the Eldfast system, but that involves ripping the insert and surround off the wall and replacing afterwards. THey insert a 'plug' into the chimney and winch it up from bottom to top whilst continually puring a ceramic alumni cement mix down the chimney. Total cost by the time I have made good is about £2000 I suppose.

The link you sent me did help a lot to describe the different methods available and helped me make my mind up. Thanks again, and I will post again when the work has been completed to let people know if it worked!

Hi again.

is there any chance of contacting the NACE to see if there are any other installers in the area? may be that you can get the work done cheaper elsewhere?

Sorry about the cross over as regards what system we were both discussing, the last time I used that system [ mid 80s ] the firm installing was called "scot lum" I do not think they are still trading?

Would be interested to hear how it all goes?

Cheers, good luck.

Ken.

Sorry Ken, who are the NACE? I googled it and cae across all sorts of things but nothing related to fires and chimneys.

Thanks

Hi,

Just wanted to clear up a couple of misunderstandings about Eldfast:

On average, it costs about £1500+vat to line a chimney using Eldfast. It would only cost a lot more if it's a particularly large or difficult chimney.

It is also very rare that a fire surround would need to be removed/replaced to apply Eldfast. As a precautionary measure, dust sheets are used to protect furniture in the room from soot, dust and the mixture.
