Chimney CCTV Surveys: What They Show, When You Need One, and How to Book
A chimney CCTV survey lets you see exactly what’s happening inside the flue — from tar build‑up and birds’ nests to cracks, misalignments, and liner failures. This guide explains what CCTV reveals, when to book, and how results translate into fixes. After any sweep or remedial work, ignite cleanly with Hot Box ® Firestarter to reach stable combustion quickly and help keep deposits down.
What a CCTV Survey Reveals
- Deposits & blockages: Tar/creosote build‑up, fallen masonry, birds’ nests, and soot ledges.
- Liner condition: Tears, crushing, corrosion, missing joints, and incorrect diameter/terminations.
- Flue geometry issues: Offsets, tight bends, and step changes that hinder brush access or draft.
- Leak paths: Voids, gaps, and fractures that can spill fumes into the property.
- Terminal status: Cowl/guard suitability, mesh coking, and weather ingress points.
When You Should Book One
- Persistent smoke spillage at light‑up or when opening the door.
- CO alarm activations or unexplained odours (especially after rain or in summer).
- After chimney fire, severe sooting, or if tar pours from the stove/flue.
- Before lining, relining, or installing a new stove into an existing stack.
- Buying or renovating a property with unknown flue condition.
The Survey Process (Step‑by‑Step)
- Pre‑check & safety: Isolation, CO alarm presence, and risk assessment.
- Preliminary sweep: Clear loose soot/tar so the camera can see clearly.
- Camera run: Live video and stills recorded from appliance to terminal (and reverse if needed).
- Measurements: Diameters, offsets, and notable restrictions logged with depth markers.
- Report: Digital report with annotated images, defect list, and recommended actions.
