Chimney Camera Inspections: What They Show and What They Do Not

Why a camera is used

Much of a chimney is hidden: the flue interior, the joints between liner sections, the smoke chamber, and any offsets or bends. A camera on a rod or a cable lets the inspector view these areas. In CSIA terms, a Level 2 inspection includes a video scan or other means of examining the internal surfaces and joints of the flue liners. See the inspection levels guide.

What it can show

• Cracked, missing, or displaced liner tiles
• Open or deteriorated joints between liner sections
• Creosote or soot deposits and where they sit
• Obstructions such as debris or nesting material
• Problems in the smoke chamber area, depending on access
• Whether the flue is lined at all

What it cannot do

• It does not replace an inspection of the firebox, damper, crown, cap, flashing, and masonry
• Picture quality depends on lighting, deposits, and how far the camera can travel
• Some defects, such as hairline cracks or movement behind the liner, may not be visible
• A dirty flue may need cleaning first to see the surface clearly
• It does not measure clearances or hidden construction behind walls

What to expect

The inspector places the camera at the top or bottom and advances it through the flue while watching a monitor. Findings are described, and some providers record images or video. Ask whether you will get a copy. When you schedule an inspection, ask what equipment will be used and what you will receive afterward.

Questions to ask

• Will the whole flue be scanned, and what will be left unseen?
• Does the cleaning come first?
• Will I receive photos, video, or a written summary?
• How do the findings translate to repair options?
