How to safely take care of your chimney

A poorly-maintained chimney is a major fire risk. These tips could keep your chimney working properly and keep your family safe.

The upper part of a chimney takes a beating from wind and the weather. Don't make it more vulnerable by attaching a TV antenna or satellite dish to it. Also, have the chimney inspected yearly for damage.

The mortar around the bricks or stones that face your chimney may loosen or crack and need repair (a process called tuckpointing). These are jobs for a mason and should be done as soon as possible.

• The joint between the chimney and the roof is protected by a series of overlapping pieces of metal called flashing.
• If flashing is damaged or worn, water may seep into the chimney.
• A roofer can replace the flashing, but any damage to the masonry will require a mason.

• The inside of a chimney is subject to enormous temperature extremes and buildup of creosote and toxic gases.
• It's not surprising that linings deteriorate over time and need replacing.
• Chimneys can be relined with flue tiles, poured concrete or metal. The choice depends on the size of the chimney, local weather conditions and the type of fireplace served.
• Consult a professional and have a professional complete the job.

• Metal flue caps, which are inexpensive and easy to install, can prevent water damage and stop animals from nesting inside your chimney.
• Measure your chimney top and buy a flue cap to fit it. Slip the cap over the top of the chimney and tighten the screws.
• If you aren't comfortable climbing onto the roof, hire a roofer or a chimney professional to put on the cap

• Chimney fires can burn quietly for a while and then cause havoc.
• If you suspect a chimney fire, close the damper to the fireplace and the damper and all air outlets to the stove, if you can safely reach the handles.
• Get everyone out of the house. Then, call the fire department from a neighbour's house.
• Wet down the roof with a hose.
• Deprived of oxygen, most chimney fires will die out quickly. But if flames break through a crack in the flue, or if burning ashes fall on the roof, the whole house could go up in smoke.

Proper chimney care is essential even if you don't use your fireplace. Keep it well-maintained and looked after by the professionals for the best performance.
