Cavity Wall Camera Inspections tell you exactly what’s happening inside your walls – often the missing piece in a wider retrofit assessment or energy survey, and the fastest way to separate a genuine insulation problem from a false alarm.
A neglected or poorly filled cavity can mean cold rooms, higher energy bills, and – in the worst cases – damp working its way through from the outer leaf to the inner wall. But cavity condition is invisible from both inside and outside the property, so problems tend to surface as symptoms (a cold room, a damp patch, an EPC that doesn’t add up) long before anyone knows the cause.
Our borescope inspections have supported retrofit and energy assessment work across social housing, commercial buildings and private homes alike, typically as part of a wider retrofit assessment or energy survey rather than a standalone check. That combination – diagnostic testing paired with the retrofit and energy assessment expertise to act on what it finds – is what gives clients an evidenced answer rather than a guess before any decision is made on what to fix. Learn more about cavity wall inspections in our FAQ section below.
Why work with us?
Experience
From ruling out a structural cause for reported damp across 28 retirement flats at Anchor Properties, to uncovering completely uninsulated 1960s cavity walls during a full energy survey at Horfield Health Centre, our borescope inspections give clients a confirmed answer about what’s actually happening inside their walls – not an assumption.

Understanding Cavity Wall Inspections: Your Questions Answered
What is a cavity wall?
Most homes built after the 1920s have cavity walls – two separate layers of brick or blockwork forming the external wall, with a gap or “cavity” in between, originally designed to stop moisture passing from the outer wall to the inner one and to act as a natural insulator.
What is a cavity wall camera inspection, and how is it carried out?
It’s a minimally invasive way of seeing what’s actually inside that gap. We use a borescope – a thin, flexible camera on a tube – to check for the presence and condition of insulation, signs of damp, and any debris or blockages. In practice: we inspect the outside walls for obvious issues, drill a few small 8mm holes in the mortar joints, insert the borescope to take photos, then seal the holes with a weatherproof sealant. You get a detailed report with the findings and any recommendations.
Do you offer this as a standalone service?
Usually not on its own – a cavity wall inspection is normally commissioned as part of a wider retrofit assessment or energy survey, where it helps confirm exactly what’s driving a building’s energy performance rather than being assessed in isolation.
Can a cavity wall inspection rule out insulation as the cause of damp?
Yes – and it’s often just as useful for ruling a cause out as confirming one. On a 28-flat retirement development for Anchor Properties, borescope surveys found the cavity walls were properly filled with no structural cause for the reported damp, redirecting the fix toward ventilation instead of an expensive fabric intervention.
What happens if the inspection finds missing or damaged insulation?
It gives you the evidence to prioritise the right fix rather than guessing. During a commercial energy survey at Horfield Health Centre, a cavity wall inspection found the building’s original 1960s section had no insulation at all, while a later extension had some but not enough to make a meaningful difference – a finding that directly shaped a fabric-first improvement plan ahead of any heating system upgrade.
What are the benefits of an inspection?
Knowing the true condition of your cavity walls lets you improve energy efficiency by fixing genuine heat loss, prevent damp and mould by finding and addressing the real cause of moisture, avoid costly guesswork by catching problems before they escalate and get certainty about a hidden part of your building before specifying any retrofit measures.
Who do you deliver cavity wall inspections for?
