If you have stayed for many years without cleaning or doing any maintenance work on your fireplace chimney in Suffolk County NY, it about time you hired a chimney repair contractor to check it out. A chimney that is not maintained properly can malfunction in various ways. After enough fire burning, creosote can build up inside the chimney. If the creosote is not cleaned, it can catch fire. Soot can also build up in the chimney and release dangerous carbon monoxide back in your house, something that can in turn lead to lethal consequences.
