The best time of the year to have your chimney swept and inspected is during springtime, once the heating season is over. If you leave deposits in the system, the humidity of summer causes corrosion of the steel portions of your chimney.

By having your chimney swept and inspected during springtime you make sure that you have enough time to order spare parts and make necessary repairs before the next heating season. Also, if your chimney reeks of creosote on a muggy summer day, a sweep come springtime removes 80% of this bad smell.
