Video evidence in cases of insurance claims:

 

Some insurance companies require periodic 'visual' inspections of chimney flues and a condition report especially in thatched properties as part of the insurance requirements.

 

Checking for damage after chimney fire.

 

Corrosion within a metal liner.

 

Checking because of poor flue operation or suspected leak.

 

CCTV surveys are often requested by local Authorities, Letting Agents, The National Trust, Home buyers/sellers  requiring a video and report on flue condition in conjuction with general inspection regarding overall condition and compliance of installations.

 

These surveys may include a smoke test on the installation/flue as part of the inspection.

 

Smoke testing (integrity test) can reveal a failure in the system that may not be obvious by CCTV alone and can provide the client with visual confirmation of a leaking flue.  The camera inspection will assist in determining the best course of action required if any.

 

What is the procedure?

First the chimney/liner is thoroughly cleaned this will expose the surfaces of the flue.

 

A flue integrity test (smoke test) may be performed prior to CCTV survey or subsequent to it depending on circumstances.

 

CCTV system set up and inspection will begin. The camera may expose fissures in the flue, missing masonry, failed mid feathers, cracked, misaligned or damaged clay flue liners, failed connections or degradation of a metal liner. This can be recorded and may be required later for detailed analysis on a larger tv/laptop screen. A copy together with a report and any recommendations is then sent to the Client.
