Survey types

  1. look and go see. This is not a survey in a true sense as no official report will be generated. It is used simply to see if a given blockage such as a birds nest has been fully removed. Or maybe to Find if there is a cap on top which you cannot see from the roadside.
  2. Full chimney survey with report and pictures or video. This type of survey is much more in depth you will have to assess the safety of the chimney, wether it conforms to building regulations, the condition of the lining, wear and tear, water damage, major structural faults such as missing bricks, protruding objects such as RSJs,  suitability for use amongst many other things. All findings must be professionally documented with attached photographic evidence along with your expert statements.  This type of full survey carries a significant risk  to the surveyors  as such professional indemnity insurance is required. This is the type of survey you would undertake on a thatch property of maybe a party wall disagreement.
  3. Full structural survey.  This type of survey is often undertaken along with an engineer or surveyor. As the name suggests it must not be undertaken without expert input.

Camera Types

  1. Look and go see.  This is a basic camera that looks straight ahead, it has minimal functionality and is suited only to look and go see surveys. These cameras are often cheap but cannot serve the purpose of a full survey camera.

It has the ability to tilt the camera head to look 90 degrees side to side and pan 180 degrees this is necessary to scan the interior walls if the flue. Is has a record function and image resolution is usually very high. The downside is this type of cctv chimney survey camera is typically very expensive and is quite fragile requiring expert users.

    Love my VIS400, would not be without it, looking forward to the review, the new light ring is a vast improvement, pan and tilt is absolutely the way forward. Do you have the big flightcase?

      yes pan and tilt is the only way you can actually survey the walls of a flue.
      I don’t have the add on light ring but do have the flight case. A peli case would be much better for this type if kit imo.
