Waterproof your chimney and do not let rain water seep into your chimney. The waterproofing will prevent long-term corrosion and masonry damage.

Get your chimney flashing inspected and maintained from time-to-time. By keeping the flashing functioning, you can prevent rainwater and snow melt from entering your home and damaging the walls and ceilings of your home.

For an annual repairing of your chimney you should opt for the month of Spring. For the purpose you should get your chimney checked by a CSIA Chimney Sweep.
