Why do I need to clean my chimney ?
Most homeowners are aware of the need for chimney cleaning, if they own a wood - burning stove or regularly use their fireplace but many don't realize that a gas heating appliance - whether it is a furnace, boiler or hot water tank relies on a chimney for proper venting of the exhaust.  Appliances fueled by natural gas may not produce the visible soot that appliances burning other fuels do, but they can deposit corrosive substances in your chimney, in many cases these acids may wreak havoc on your chimney without producing symptoms.

We recommend to clean your chimney every 5 years.
