About wall tie testing
What the service involves
Wall tie testing is the process of checking whether the metal ties inside a cavity wall are still doing their job. Ties connect the outer and inner leaves of brickwork across the cavity gap, and when they corrode they can swell, crack the mortar joints or lose their grip entirely. Testing identifies which ties have failed, which are at risk and which are sound, so a decision on remedial work is based on what is actually there rather than on the age of the building alone.
The service suits homeowners who have spotted horizontal cracking along mortar joints, surveyors who need a condition report before a sale or purchase proceeds, and property managers dealing with a block where the original build date puts the ties in a higher-risk bracket. A specialist visits the property, locates the tie positions and uses a calibrated pull-test or borescope inspection to assess their condition. A written report follows, setting out findings and any action required.
Key facts at a glance
Wall tie testing across the UK: what the process involves, when it is needed, and how to arrange a specialist visit.
How it works
How the work goes
Booking confirmed
You request a free quote, give the property address and any known details about wall type or age, and a specialist confirms the scope and price.
Access and inspection
The specialist visits the property and locates tie positions by scanning the outer leaf at the standard grid spacings used during original construction.
Load testing
Each selected tie is tested using calibrated equipment to measure pull-out resistance, recording whether the tie holds to the expected load or shows signs of failure.
Written findings issued
A report is produced listing each tie tested, the load recorded and whether the results indicate corrosion, failure or satisfactory condition.
When wall tie testing is worth arranging
Do any of these apply to your property?
- Horizontal cracks running in a regular pattern along mortar joints, typically every four to six courses up the outer leaf
- The property was built between 1920 and 1980, when mild steel ties were standard and corrosion is now a known risk
- A surveyor or structural engineer has noted possible tie failure in a report but has not yet confirmed the extent
- The outer leaf of brickwork appears to be bowing or leaning away slightly from the inner structure
- A mortgage lender or conveyancer has asked for written evidence of tie condition before the transaction can proceed
- You are planning render, cladding or external insulation and need to know whether the existing ties can carry the added load

What's involved
What affects wall tie testing
Tie type and age
Mild steel ties used in cavity walls built between the 1920s and 1980s are the most common subject for testing. Galvanised ties from later decades corrode more slowly but are not immune. The specialist identifies the tie generation during the visit, which shapes how the test results are interpreted.
What the test actually involves
The specialist uses a calibrated pull-out test device to measure the load a tie can carry before it fails or moves. Readings are taken at a sample of tie positions across the wall. The results show whether ties are still structurally sound or whether corrosion has reduced their capacity below an acceptable level.
When a mortgage lender requests testing
Buyers and their solicitors sometimes receive a requirement for wall tie testing as a condition of a mortgage offer. A written test report from a specialist, covering the method used and the results recorded, is usually what the lender needs to proceed.
