Our quadrafire is in our basement, which is a walk-out patio. The chimney for this is three storeys high on our large house. We burn this quadrafire often, but lately noticed soot on our patio, first and second storey window sills, etc. Is this normal? We also have some soot staining on the limestone that caps off the chimney, which is all brick. The quadrafire has a metal cap type thing on top, not the clay caps like our other chimney flues. Anyway, it seems abnormal to have soot on our yard, patio, window sills,etc. What causes this? What can we do? We've been using it this winter and last in our new construction home and next week this chimney will be inspected and cleaned. My husband uses wood he cut from logs from trees that have been dead awhile and the logs are seasoned about 9 months I think. Recently we have burnt seasoned wood we bought locally. I'm not happy with the staining on the top of the chimney on the exterior of our house or the soot everywhere outside. Please help! Thank you.
