Advice needed: There are 2 unused brick chimneys we have to remove in an old two–story house my son and I are rehabbing. We have quite a bit of experience at rehabbing but have never taken down chimneys before and would like advice on the best, shortest, safest way to do it and which are the best tools to use for the job. We at first thought we would spread plywood on the floors around the chimneys then hammer away at the grout lines with cold chisels and heavy hammers. On reflection, though, that seemed rather old fashioned and heavy-handed so we thought we should check with fellow handyman adventurers who might have good advice to pass on. Thank you very much.
