About wall tie surveys
What the service involves
A wall tie survey gives a full picture of the ties across a property, covering their location, spacing, type and condition. The specialist maps where the ties sit within the cavity, checks a representative sample using a borescope camera and records any signs of corrosion, displacement or mortar joint cracking. The findings go into a written report that shows the overall condition of the wall and flags any areas where ties have failed or are close to failing.
This type of survey is commonly requested before a property changes hands, after a structural engineer notes horizontal cracking in a pre-purchase report, or when a building is approaching an age at which original mild-steel ties are known to deteriorate. Cavity walls built before the mid-1980s often contain ties with a thin zinc coating that can break down over time. A survey carried out by a specialist provides the documented evidence needed to decide whether replacement is required and, if so, on what scale.

How it works
How the work goes
Quote and briefing
You request a free quote, give the property address, wall construction type and any visible signs of concern, and a specialist sets out what the survey will cover.
Wall scanning
The specialist scans the outer leaf at regular intervals to map tie positions and flag any areas where ties appear absent or irregularly spaced.
Condition checks
Where corrosion or expansion is suspected, mortar joints are opened at selected points so the tie condition can be assessed directly.
Survey report issued
A written survey report is produced showing tie distribution across each elevation, condition findings and any recommendations for further testing or replacement.

Do any of these apply to your property?
- Stepped cracking has appeared in the brickwork and a structural cause has not yet been ruled out
- The building is a 1950s or 1960s cavity construction and has never had the ties formally assessed
- An insurer has requested documented evidence of wall tie condition following a claim or renewal query
- You are purchasing a property and the vendor cannot produce any record of a previous wall tie inspection
- Render or external cladding is being removed and the condition of the ties beneath is unknown
- A neighbour in the same terrace or block has recently had tie failure confirmed and you want your property checked

What's involved
What a wall tie survey covers
How the specialist locates ties without opening the wall
A calibrated covermeter or metal detector is passed across the outer leaf in a systematic grid pattern. This picks up the position and approximate depth of each tie. Where a tie cannot be detected, or where the reading is ambiguous, a small drill hole may be made to confirm what is present.
The written report
After the visit the specialist produces a dated report setting out the tie type identified, the spacing found, the condition indicated by the survey, and any areas of concern. The report records the survey method used and can be submitted to a mortgage lender, a local authority building control officer or a structural engineer as part of a wider assessment.
Buildings most likely to need a survey
Cavity walls built between roughly 1920 and 1981 used ties that are now old enough to have corroded significantly in many cases. Properties in coastal or exposed locations tend to show faster corrosion. A survey is also common before a sale, after visible cracking appears in the outer leaf, or when a lender flags the property age as a concern.
