Filling old flue opening Fillers, sealants and adhesives for all types of DIY work. Help, advice and information on all aspects of this subject

[verve]

Hi

I have had an old boiler removed and re-positioned. The old flue opening through a double skin external wall has been left (approx. 125mm diameter) and is open to the outside.

Can anyone tell me please what the best way is to fill the opening?

Many thanks

Bricks, sand and cement. Internally plaster it over afterwards.

brick up and plaster internally. either cut out ext brickwork and replace with new complete bricks or brick up slightly below surface, render over and mark into square with straight edge so looks tidy
