What Happens During a CCTV Chimney Inspection?
A standard sweep clears soot and debris, but it can't tell you what's happening deep inside the flue. That's what a CCTV inspection is for, and it's worth understanding before you book one.
What It Actually Involves
A CCTV chimney inspection uses a camera on a flexible rod to survey the full length of the flue from the fireplace or stove up through the chimney. It typically adds around 20-30 minutes to a visit and is often combined with a standard sweep.
What We're Looking For
Cracks or gaps in the flue liner, which can let heat or fumes escape into the surrounding structure
Old or deteriorating repairs that may no longer meet current standards
Structural movement, such as bulging or misalignment
Blockages from nests, debris, or masonry that's fallen from higher up the stack
Whether the flue is correctly sized for the stove or fire you're using, or planning to install
When You Actually Need One
A CCTV inspection isn't required for every routine sweep, but it's genuinely worth having in a few common situations:
Buying a property with an existing open fire or wood burner you plan to use
Moving into a period home where you don't know the chimney's history
After a chimney fire or suspected blockage, to check for hidden damage
Before installing a new stove, to confirm the existing flue is suitable
If you've had ongoing smoke, smell, or draw issues that a standard sweep hasn't resolved
What You Get Afterwards
You'll get a clear picture, literally, of the condition of your flue, along with an explanation of anything found and recommendations if repair work is needed. This is particularly useful ahead of a house purchase, since it gives you concrete information rather than guesswork before you commit.
