Inspections of Chimney Interiors using Closed Circuit Televion Cameras

Reveal the true condition of your chimney in full colour!

 

Recorded on videotape, you can view at your own leisure, and see for yourself whether repairs, e.g. relining or rebuilding are truly needed.

 

  • Have Repairs or Relining already taken place?
  • Have the repairs been carried out properly?
  • Does the new lining go right to the top of the chimney?

 

We can make a video tape of the entire inner surface of your Chimney. In full colour, this will enable you to see precisely where in the chimney any needed work should be carried out. If repair work has already been carried out you will see whether it has been carried out to your satisfaction. All is revealed in full colour detail.

Here a builder when relining this flue found it too difficult to go past this projection he gave up and stopped 4ft short of the chimney pot, the householder was able to get him to return and finish the job properly when he was confronted with this evidence. The top of the chimney is generally the weakest part and is most in need of repair. But since you are unlikely to check his work, an unscrupulous builder can cut corners, and leave you with a still unsound chimney, that could be very dangerous. It is worth checking, as you can see from this picture.
In this case the chimney relining firm had not centralised the rubber tube used to form the new flue when they were pumping in the lightweight concrete lining, the result as you see is that the new lining material has not adhered to the old flue wall, leaving a defective lining in a defect old flue, this too was able to be rectified as a result of this video evidence.
In this picture you can see a hole through from one chimney into the neighbouring chimney, fortunately they were both no longer in use, but since the householder wanted to put them both back into use, he wisely decided to have a video inspection carried out to ascertain the condition of the flue first, boy was he glad he did.
When opening up an old flue to bring back into use an old fireplace it is wise first to see if it is safe to use. If you see smoke coming out of the slates as well as the chimney pot then there is something very wrong as seen here. See just how close the hole in this flue is to the wooden beams, a potentially very dangerous situation. Fortunately it was discovered before it was too late.
Here is a view of the crown of a chimney stack. Being able to see this is also valuable as it might show such defects as seen in the bottom left of the picture, a small crack in the concrete that can allow water to enter, with frost the crack will enlarge causing further damage. The next door neighbour would be wise to seal the bottom of his gas terminals with silicone sealer too, as rain water will seep in around the slight gap between it and the pot. A stitch in time as they say
This picture shows a severe break in the mid-feathers of a chimney allowing the fumes from one chimney to pass into the flue of another chimney. It is an extreme hazard as if either of these chimneys catch fire both properties could go up in flames. Or carbon monoxide can leak from one to another with disastrous results
Here we see again a chimney were the lining has not been taken right to the top of the chimney. Yet the house owner paid for a lining to be completed right to the top. As always it is the top of any chimney that is the weakest since this is were the effects of both the weather and the damp soot take their toll. Therefore it is the places were the lining is needed most.
Here we see the top of a chimney were there are no pots fitted it shows the effects of the elements and acids from soot, the cement between the bricks is eroding and the chimney stack is be coming weak needing repair
Here we see from the top of a chimney a view of the other terminals of flues on the stack these are ventilators allowing the disused flues to breath. Such caps cannot be used on chimneys burning solid fuel.
