If you plan to fire up your fireplace again this winter, consider having a professional inspect your chimney and flue. These professionals look for cracks in the masonry, water damage, and other signs of wear and tear.

Excessive Soot or Creosote Buildup

Creosote is a black, tar-like substance in your chimney as wood burns. When it becomes excessive, it can block the flow of smoke into the flue. This can lead to smoke blowing back into the house, which can trigger allergies and aggravate respiratory conditions like asthma.
