Need a WETT Inspection or Chimney Sweep in London, Ontario?

While burning dry wood is highly recommended, it does not eliminate creosote entirely. Every log you burn leaves behind traces of soot and tar; creosote forms when these tar droplets condense on the relatively cool inner walls of your chimney. Furthermore, how you burn the wood is just as important as the wood's quality. If you frequently have "smoldering" fires rather than hot, active ones, or if your chimney’s configuration causes smoke to cool too quickly, creosote will accumulate much faster regardless of how dry your logs are.

You should book a professional sweep right away if you notice any of the following:

• Smoke Spillage: If smoke is drifting back into your room instead of venting upward, it often indicates a "draft issue" or a dangerous blockage.
• Strong Odors: Unpleasant, acrid creosote smells coming from the firebox are a sign of significant buildup.
• Visible Buildup: If you can see a layer of soot or tar thicker than 3 mm (1/8 of an inch) on the chimney walls, the National Fire Code considers it a potential fire hazard that requires cleaning.
• Physical Obstructions: Evidence of bird nests, animal activity, or falling debris inside the flue.

Yes. Fire safety standards recommend that wood-burning systems be inspected and cleaned at least once a year, regardless of how much you use them. This ensures that even small amounts of buildup are removed before they become a hazard. If you use your fireplace as a primary heat source and burn through three or four cords of wood in a season, you may actually need an extra mid-season sweep to stay safe.
