When I bought the house I had a couple of the old coal braziers converted to fireplaces. That meant relining the chimney from bottom floor to top. In this photo you can clearly see the line between where the old wall was left intact and where new Sheetrock covers the repaired flue pipe. What's not so clear: why it's taken me more than a couple of years to sand out the patch and paint over it. I guess that in a house such as mine anything short of a complete overhaul feels like you're just whistling in the wind.
