When Do I Need a Chimney Camera Inspection?

By the Miles Chimney Sweep team · Published Aug 21, 2026

You need a chimney camera inspection whenever something may be wrong inside the flue and no one can confirm it by looking from the fireplace or the roof. The most common triggers are buying or selling a home, a suspected or known chimney fire, an earthquake or major storm, switching or relining an appliance, or ongoing symptoms like a smoke smell, poor draft, or debris dropping into the firebox.

Here is the part most homeowners miss: the interior lining is the one section of a chimney that matters most for safety and the one section you cannot see with a flashlight. A camera is simply how a professional puts eyes on it.

What a Chimney Camera Inspection Actually Is

A camera inspection uses a specialized, high-temperature-rated camera on a long rod or cable that is fed through the flue. The technician watches a live video feed of the interior lining from top to bottom, checking the clay tiles, metal liner, or masonry for cracks, gaps, deterioration, offsets, and buildup. It is a visual method for examining the one part of the chimney that is otherwise sealed off from view.

Nationally recognized fire-safety guidance treats video scanning as part of a more thorough evaluation, not the routine annual check. Under the widely used NFPA framework, a standard annual (Level 1) inspection covers readily accessible areas, while a Level 2 inspection - the one used for home sales, after events, and after system changes - adds video scanning of accessible internal surfaces where practical. If you want the full picture of how those tiers differ, our guide to chimney inspection levels breaks it down.

When You Genuinely Need One

• Buying or selling a home. A general home inspection typically looks at the visible exterior and firebox only. Before a chimney changes hands, a camera scan confirms the hidden lining is intact rather than assumed to be.
• After a chimney fire - even a small or suspected one. Heat can crack flue tiles and warp components out of sight. Do not use the system again until it has been scanned; see what to do after a chimney fire.
• After an earthquake or major storm. Seismic movement and heavy impacts can shift or crack a liner internally with no visible outside damage. This matters especially for older masonry chimneys - more on that in our article on inspecting a chimney after an earthquake or storm.
• When you switch or reline an appliance - for example, adding a wood or gas insert, or changing fuels. The flue has to be correctly sized and sound for the new appliance.
• When symptoms appear: a persistent smoke or campfire smell, a fireplace that will not draft, water stains near the chimney, or bits of tile or mortar dropping into the firebox.
• When a routine inspection finds something concerning. If a technician sees evidence that suggests interior damage, a camera is how that concern is confirmed or ruled out.

When a Camera Scan Usually Is Not Necessary

If your system is used seasonally, has been maintained on a regular schedule, and shows no symptoms, the standard annual inspection is generally the right level of care. A camera scan is triggered by a reason - an event, a transaction, a symptom, or a finding - not performed on every visit by default. A reputable company will explain why a scan is being recommended rather than adding it automatically.

What the Camera Can Reveal

• Cracked or spalled clay flue tiles
• Gaps or missing mortar joints between tiles
• Glazed (hardened) creosote that a standard brushing cannot remove
• Blockages such as animal nests, debris, or collapsed material
• Corroded or separated metal liners
• Offsets and construction defects hidden inside the run

None of these are visible from the fireplace opening, which is exactly why a camera exists.

What You Can Do as a Homeowner

You can safely watch for the warning signs above and keep track of your chimney's history - when it was last inspected, whether it has had a fire, and whether anything has changed with the appliance. What you should not do is attempt to inspect the interior yourself by climbing onto the roof or reaching into the flue. The evaluation that requires special equipment is exactly the part to leave to a professional. When you are due for routine care, our overview of how often a chimney should be swept is a good starting point.

Preventing Surprises

The best way to avoid an emergency camera scan is a consistent annual inspection, prompt attention to symptoms, and a scan at the natural trigger points - a home purchase, after an event, or when changing appliances. Catching a hairline liner crack early is far less costly than discovering it after it has spread. If you are unsure whether your situation calls for a camera scan, describing what you are seeing to a professional is the fastest way to find out.
