At least once each year you should have your chimney checked and cleaned if necessary, by a chimney professional. If you heat with wood, or if special circumstances of your chimney system warrant it, it may be wise to have the chimney checked more frequently.
When is the best time to have the chimney checked?
If you haven't had it done this year, then now! But for routine maintenance, early spring, after the heating season is over, is the best time. Chimney cleaning in the spring leaves the chimney free of corrosive and foul- smelling soot deposits during the hot, humid summer months. And in the fall, you will be ready for the cold weather.
