Filling in a flue vent hole

bungaro79 · 02-08-2019 04:33PM #1

Hi
we're getting rid of a stove which was already in the house we bought two years ago. The vent goes out the wall behind it and it looks like it was filled in properly so I'm wondering if I can just use an angle grinder to cut it flush with the wall? A local fella said just to fill in the hole with expandable foam but I'm wondering if this is a good long term solution?? I've never done anything like this before so any advice is welcome.
Thanks

Is it an external flue mounted to the house outside or is it a chimney flue ? Important distinction

Hi listermint
That section in the picture is one solid piece going through the wall if that answers your question?!

I'd remove the entire flue.and brick up the hole. Maintaining any cavity in the wall. Then plaster the inside and render the outside. I wouldn't be spray foaming that it's not a job for foam.

A flea and a fly in a flue
were caught so what could they do?
Let us fly, said the flea
Let us flee, said the fly
So they flew through a flaw in the flue.

If you take and angle grinder and just take off the ends of the pipe (not flush with the wall leave it all sticking out) you should be able to pull out the central section of the pipe and a load of insulation. Once you have done that you can probably collapse the rest of the pipe so it can be pulled out. If you bash it in one spot on the outside so you are folding the pipe into itself eventually you should be able to revolve it a bit and eventually get it smaller than the hole and be able to pull it out. Or you could cut the pipe almost flush pull out the inner pipe and insulation then reach into the pipe from either end with the angle grinder and cut the pipe down one edge. Lever up and edge where its cut and grab it with a pair of mole grips (watch your hands and wear gloves that stainless can be sharp when cut) then you can roll the pipe up smaller in the hole so it pulls out.

I hope that sort of makes sense
