The chimney sweeps are now chisling and pulling out the liner; it is packed within 8 feet of the top of the flue, the previous installer put on a cap, but no mesh, so the birds have been flying in and out of there for all this time. There is no way to get the packed mess out without destroying the liner, so we have to have a new liner put in; it will be Saturday or Sunday unless someone cancels. Sigh!
