how much should a chimney liner cost?
We have a c. 1860 house with a 21" x 21" unlined masonry chimney venting our gas fired steam boiler. Our boiler is almost dead (i.e., leaking steam up our unlined chimney) and we are looking not only to replace the boiler, but also to install a liner. The chimney is about 40 ft. tall and has a single flue. There is a slight "jog" in the chimney (see online pictures for condition - http://new.photos.yahoo.com/shesingh/album/576460762390379745).
We have been interested in doing a cast-in liner kind of installation (e.g., supaflu) to reinforce the chimney structure since it is so old and has been exposed to corrosive steam this season, but the estimates have seemed outrageous! What should we expect to pay for this type of system? How about for a stainless steel liner? We need an 8 or 9" flue. We also know that we will need to rebuild at least the corbel part of the chimney.
Thanks in advance for any help!
