Inspections & Testing


CCTV Inspection

A CCTV Camera inspection of a flue enables us to detect the existence of many hidden chimney problems, such as breaches in the chimney flue wall, blockages from poorly installed chimney liners, bird nests, fallen debris, or damage to the flues and brick work.

This survey will also show up problems like heavy tarring (Read More ⇨). We use a state-of-the-art chimney CCTV inspection camera for all inspections, which allows precise chimney inspection by being able to tilt 180 degrees and pan 360 degrees remotely.

A recording of the chimney inspection can be made onto a suitable format or photos provided for you or your insurance company. A detailed report can also accompany this recording, outlining the condition of the chimney flue shaft plus the exterior of the stack among many other key points and noting any recommendations for any remedial action if needed.

Please note that a chimney would need to be properly cleaned in advance to facilitate a Chimney CCTV inspection Survey

Smoke & CO2 Testing

Carbon Monoxide safety is something that all households should be aware of, and if there is any doubt about the condition of a chimney, or if an old chimney is to be put in use after a long period of disuse, it is advisable to have it Smoke & CO2 tested.

We also recommend that a smoke test is carried out during the construction of masonry chimneys, and on completion of all chimney installations. Smoke tests should also be carried out where there is (or was) a gas fire. A smoke test should only be carried out by a qualified person

The purpose of a smoke test is to identify any faults which would cause fumes to escape during the normal operation of an appliance and chimney. Closing the bottom and top of the chimney during the test, will generate a positive pressure in the flue. This will force the smoke, generated by the pellet, to escape through gaps in the joints in a masonry chimney, or connections between pre-fabricated metal chimneys and flue pipes.

Minor leakage detected during this test, would not be a major risk when the installation is used during normal operating conditions, providing the point of leakage does not indicate a fault that could get worse. However, if significant or heavy smoke leakage is seen, the cause must be investigated and rectified. Broken components, incorrect fitting and incomplete jointing of flue liners are the most common problems which cause major leakage and require remedial action
