Professional Cavity Wall Tie Surveys for Residential Properties
Cavity wall ties play a critical role in holding a building’s external and internal walls together. Over time, these metal components can deteriorate, corrode, or fail, often without visible signs at first. A professional cavity wall tie survey provides a detailed assessment of their condition, helping identify risks before they develop into structural issues.
At Surveying Cymru, our specialist surveyors carry out cavity wall tie surveys across South Wales, Herefordshire, and Gloucestershire. We provide independent inspections and clear reporting, giving homeowners and buyers a reliable understanding of wall tie condition and any action that may be required.
What Are Cavity Wall Ties and Why Do They Matter?
The Role of Wall Ties in Construction
Wall ties are metal connectors built into cavity walls to link the outer and inner leaves. They provide stability, helping the wall act as a single structure while allowing for slight movement and moisture control within the cavity.
If wall ties fail, the two leaves can begin to separate, which may lead to cracking, bulging walls, or, in more serious cases, structural instability.

What Is a Cavity Wall Tie Survey?
A Targeted Structural Inspection
A cavity wall tie survey is a focused inspection that assesses the condition, spacing, and performance of wall ties within a property. The aim is to determine whether ties are functioning correctly or showing signs of corrosion or failure.
Unlike a general house survey, this inspection specifically investigates hidden structural elements that cannot be assessed through visual checks alone.
Signs You May Need a Cavity Wall Tie Survey
Wall tie issues are often hidden, but certain signs can indicate a problem:
- Horizontal or stepped cracking in external walls
- Bulging or bowing brickwork
- Cracks around window or door openings
- Movement between inner and outer walls
- Rust staining on external brickwork
If any of these signs are present, a professional survey is recommended to confirm the cause.

FAQs About Cavity Wall Ties
What causes wall ties to fail?
Wall ties can fail due to corrosion, poor installation, or age related deterioration.
Are wall tie problems serious?
Yes. If left untreated, they can lead to structural movement and damage to brickwork.
Can wall tie issues be seen without a survey?
Not always. Many problems occur within the cavity and require specialist inspection.
Do all properties need a wall tie survey?
Not all, but older properties or those showing signs of movement should be assessed.
Will the survey involve damage to the property?
No. Surveys use non intrusive methods wherever possible.
