Q. How often should my chimney be cleaned?
A. CSIA recommends an annual inspection to ensure the safety of you and your home. Upon doing an inspection it will be determined if a sweep is necessary. Depending on how often you burn and what type of wood you burn, will also determine how often your chimney needs to be swept. If you have between 50-80 (or more) fires a year, it is likely you need your chimney swept.
Q. What type of wood should I be burning?
A. For burning firewood in wood stoves or fireplaces, choose well seasoned wood that has been split for a minimum of six months - one year and stored in a covered and elevated location. Never burn Christmas trees or treated wood in your fireplace or wood stove. All firewood contains water. Freshly cut wood can be up to 45% water!, while well seasoned firewood generally has a 20-25% moisture content. Well seasoned firewood is easier to start, produces more heat, and burns cleaner. The important thing to remember is that the water must be gone before the wood will burn. If your wood is cut 6 months to a year in advance and properly stored, the sun and wind will do the job for free. If you try to burn green wood, the heat produced by combustion must dry the wood before it will burn, using up a large percentage of the available energy in the process. This results in less heat delivered to your home, and literally gallons of acidic water in the form of creosote deposited in your chimney.

There are commercial chimney deodorants that work pretty well, and many people have good results with baking soda or even kitty litter set in the fireplace. The real problem is the air being drawn down the chimney, a symptom of overall pressure problems in the house. Some make-up air should be introduced somewhere else in the house. A tight sealing, top mounted damper will also reduce this air flow coming down the chimney.
Q. Why is there cold air coming from the chimney?
A. This could be a drafting issue. This could also be a wind-induced downdraft and can be fixed with a wind cap. Depending on the location of your fireplace, there can be a negative air pressure. This is when the pressure in the upper levels of the house tend to be higher than the lower levels of the house due to the tendency of hot air rising. This is known as the "stack effect". This may also be resolved with a fresh air intake.
Q. Why is there smoke coming in my house while burning wood?
A. Just like cold air issues, this can be a drafting issue either from no fresh air intake or the result of pressure difference in the house.

Q. What is the animal screeching in my fireplace?
A. In most cases its a Chimney Swift. This is the only bird that can fly up and down your chimney. And they do, looking for places to make their nest. You’ll know you have these uninvited guests when you hear the baby chimney swift birds "screeching". Once these swifts have made their home in your chimney, it is unlawful to remove these birds due to their endangered status. If you have swifts in your chimney, we have to wait until the fall when these birds migrate to remove the nest and install a chimney cap.
