Chimney Breast Repointinhg Job - Fern Type Plant

[tododo]

Hi all

Im just started doing the repointing on a 1930s chimney - its needs doing as there a fern type plant attaching to the joints.

In some places its gone in quite deep and it comes out fairly easy but its quite a rooty fibrous type fern that seems to take hold on all the chimneys round here

Im going to use a grinder to get the bulk of it out but where I cant get a ginder in is there something that anyone know of that will kill it off - poison wise

Was thinking of also using my oscillating tool to get in the joints too - that may do it but not sure if its heavy duty enough

Thanks

I recently did mine, it was the same, so bad that the roots had replaced all the mortar in the top course. I removed the top course of bricks, (chimney redundant so couldn't see the point of rebuilding). I also used a multitool for raking out, partly because some of the joints were very thin and partly because I didn't feel safe using a grinder off a ladder.

Thats the stuff there - its gone right in the joint with you there too - there are a couple of loose bricks so Im glad we are doing it - although its a bit more work than I envisaged to be honest - especially the crown - theres a lump of concrete on there that we are going to need to replace Without dropping stuff down the neighbours side too.
