Is rain getting in my chimney?

If the fireplace is bricked up or you have an open fire and you notice a damp patch on the wall of the chimney breast, rain may be coming down the chimney.  A rain cowl will help stop this happening. If you notice this problem and have a woodburning stove, it may indicate that there is something wrong with the cowl or the liner in the flue.
