If you are unsure whether your property has sufficient cavity wall insulation, our borescope check is the best way of spot checking this. The purpose of cavity wall insulation is not to act like a blanket to just keep your house warm in the winter months, it's purpose is to stop air flow... so it is important not only to stop the winter cold air from coming inside and costing you higher heating bills, but also to stop the warm summer air. making inside uncomfortable With this in mind, if certain areas of your property are colder in winter or hotter in summer, you may have an issue with your cavity wall insulation.
At HomeSnag we offer 2 different services to spot check the walls: The first is alongside your snagging survey on your new-build house where we spot check a few different elevations (around 1m high) to check what insulation it is and if there are any gaps. This option will be prompted when you book your snagging survey on houses and is just £30 inc VAT.
If you have been living in your house for a period of time and have concerns over the condition of heat loss then it may be worthwhile instructing us to carry out a full thermal heat loss survey in the winter where we use the borescope to confirm our suspicions (an example shown in the below photo from a report)
The other service we provide is for customers of older houses or clients needing a commercial building surveying which require us to check the cavity in more detail. In this situation please get in touch with our office to provide a quote. An example report of a borescope inspection on a commercial building complex is provided further down on this page.

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.

Commercial Cavity Surveys
If you require a detailed survey on cavity walls on a commercial building such as a school, office or similarly large complexes, please get in touch for us to quote. An example of a report we carried out on a school is below, which provides images of the cavity alongside the specific location and summary where cavity wall insulation is missing or present.
