Cavity Wall Survey using a Borescope

The Borescope is an invaluable tool for our snagging surveys and we can carry out spot-checks on the cavity on your new-build house as an extra to the standard snagging survey.
As can be seen in these example images, it is also integral to our thermal heat loss survey process where we use the borescope to confirm suspicions of voids in the cavity wall insulation.

Cavity wall insulation in new build houses has different types which can be blown in (such as polystyrene beads) or system built (such as kingspan panels), all of which can have problems with voids or thermal bridging. However we only carry out a borescope check on traditionally built (block & brick) new-build houses and not timber frame to ensure we do not penetrate the membrane in the cavity.

Our methodology of carrying out a spot check to the walls of your cavity ensures that minimal intrusion is caused. We drill into the mortar of the brickwork and collect the mortar dust whilst doing so. We then insert the borescope camera to inspect for voids, snots on wall ties etc. Most of the time we see insulation blocking the camera! But of course we are trained to identify voids both minor and extensive that will make your house cold in the winter and too hot in the summer.
Once we have carried out the check with the borescope camera, we fill the small hole back up with weatherproof sealant and the mortar that we gathered when drilling.

Cost of Borescope Inspection

A borescope check on your house can be carried out for just £30 extra to the standard snagging survey on your new build home. For this we will spot check the cavity wall in a couple of areas, typically at the corners. We can also check the roof to your garage if integral as it is often an area that has missing insulation, making the bedroom above very cold.

If you have specific concerns about heat loss then we recommend you book our thermal heat-loss survey that is carried out in the winter months. Our survey which combines the use of a thermal camera and borescope to prove insulation issues has been invaluable for many homeowners we have visited. For further information, see our webpage on heat loss surveys.
