Like any home appliance, chimneys need their share of maintenance. Inspecting and cleaning your chimney annually is essential to fire prevention, as well as your ventilation system. This can include the chimney itself, the flue liners that keep it protected, as well as the vents that encompass the entire home. Vents, like chimney flues, are used to transfer exhaust from appliances and some furnaces to ensure your family’s safety from day to day. In high efficiency furnaces, vents may be plastic as well as metal.
Inside a chimney, the conditions are bleak. Burning wood creates creosote, an oily black substance that coats the lining of your flue, which over time can become thick enough to ignite. If this happens, and the resulting creosote fire is intense enough, it can crack the liner of the chimney itself, risking weakening it and surrounding flammable materials which can include wood framing. If this happens, a comforting evening by the hearth can turn into a full-blown house fire, which is why it is so essential to have your National Property Inspections team member visit annually for prevention. The Chimney Safety Institute recommends a cleaning once the creosote gets to ¼ inch or thicker, so if you live with the fire burning, be wary of your creosotes. However, once your chimney sweep has finished, feel free to use the leftover creosote residue in flowerbeds. It is a great source of calcium and other nutrients!
During cleaning, your chimneysweep should check the damper to ensure correct positioning, as this helps with energy efficiency. Along with the flue itself, the damper ledge must always be cleaned, while the outside should be checked for obstructions as well as normal wear and tear. A chimney cap, which serves an important function, should be in place if it is not already, because it keeps animals, rainwater, leaves and debris out, while keeping the flames held in. If you decide a wood fire is best for you, remember never to burn green wood, but to make sure it is seasoned enough to crackle.
Between inspections, it is always good to keep an eye out for rust, discoloration, or cracking, especially the areas around joints. To prevent damage should there ever be a fire, always be sure to install smoke detectors in every level of the home to properly detect and alert everyone to the hazard. It goes without saying, never forget to check the smoke detectors each month for functionality.
