Fast, Accurate Wall & Cavity Wall Surveys Without Destructive Works
At Surveying Cymru, we specialise in borescope surveys for homeowners, landlords, housing associations, and building surveyors across South Wales, Gloucestershire and Herefordshire.
If you want to check for cavity wall insulation, you can assess the wall’s condition. You can also look for dampness. Our non-invasive borescope inspections can assist you with this. We provide quick visual evidence with little disruption to your property.

What Is a Borescope Survey?
A borescope survey is a specialist method used to inspect areas inside a building’s structure that are not easily visible, such as wall cavities, voids behind rendering, or inaccessible pipework.
This is achieved using a small camera probe (borescope) inserted through a tiny borehole (typically 10mm in diameter) drilled into the external wall or area being assessed.
Unlike fully invasive inspections, borescope surveys provide visual confirmation of conditions behind walls without needing to remove large sections of masonry or internal finishes.
WHAT OUR CLIENTS SAY
What Can a Borescope Survey Reveal?
- Presence or absence of cavity wall insulation
- Type and condition of existing insulation
- Wall tie corrosion or defects
- Signs of water ingress, damp or moisture
- Confirmation of wall construction type (e.g. solid wall, cavity, timber frame, system-built)
- Presence of vermin or insect infestations
- Leaks or concealed pipework
- Obstructions or defects behind rendered external walls

Our Borescope Survey Process
At Surveying Cymru, we combine specialist equipment with local surveying expertise to ensure a thorough and professional experience.
Step 1: Initial Assessment
We will talk about your concerns. This includes suspected cavity wall issues, water leaks, or identifying wall construction. We will also suggest the best way to inspect.
Step 2: Borehole Access
A small 10mm hole is drilled in a discreet location on the external wall. This causes minimal disturbance and is carefully repaired after the inspection.
Step 3: Camera Insertion & Image Capture
Our surveyor inserts the borescope camera into the wall, capturing live images or video of the cavity or void space. We’ll assess insulation, moisture, structural components and any defects.
Step 4: Professional Report
You’ll receive a comprehensive survey report, including photos, findings, and our recommendations for any next steps such as insulation removal, damp treatment, or further investigation.
Typical Borescope Survey Applications
A cavity wall survey is commonly used to:
- Confirm if insulation is present in cavity walls
- Check for insulation failure or moisture retention
- Inspect wall ties for corrosion or damage
- Identify cavity depth for insulation feasibility
- Diagnose hidden damp or water ingress sources
- Detect infestations in wall voids or lofts
- Locate leaks or pipes behind walls or ceilings
- Verify wall build-up behind external render or cladding
These surveys are especially useful in older homes, hard-to-treat properties, or where retrofit work is being planned.
Will the borehole damage my wall?
No, the small hole is only around 10mm in diameter and is always filled after the inspection.
Can you survey through rendered walls?
Yes, we can drill through render with care and repair the surface after the inspection.
How long does a survey take?
Most borescope inspections take 30 to 90 minutes, depending on complexity.
Can I use the images for a retrofit assessment?
Yes, we provide high-resolution images and cavity depth info suitable for PAS2035/2038 assessments.
