Checking a chimney should be a concern for every homeowner because it pertains to the safety of your home and family. Each year, lives and property are lost due to improper care and maintenance of chimneys. You can check some parts of the chimney yourself. We will review those below. But other parts need to be checked by a professional.
This is why you should have your chimney checked at least once each year by a chimney professional, and cleaned if necessary. In some cases, your chimney professional will advise more frequent visits.

Inside a chimney you’ll find one or more vertical passageways called flues. Ideally, each appliance connected to the chimney (such as each fireplace, each furnace, each wood stove) has its own, separate flue. More than one flue might be contained in one masonry chimney. So if you have a furnace and a fireplace connected to the same chimney, there should be at least two vertical passageways up the inside of the chimney.
Metal factory-built chimneys, of course, contain only one passageway for venting combustion products, the inside of the pipe.
In a modern masonry chimney, the inner wall of the flue is lined with some type of material for safety, ease of cleaning, and improved performance. Among the most common types of liners are:
