Cavity walls have been widely used in UK construction since the early 20th century. They provide insulation and help prevent moisture from passing through external walls. At the heart of these structures are wall ties. Small but crucial components that connect the inner and outer leaves of a cavity wall. Over time, these ties can corrode or fail, leading to serious structural problems.

That’s where professional cavity wall tie specialists come in. At Surveying Cymru, based in Monmouth, our experienced specialist surveyors inspect, diagnose, and report on wall tie conditions, helping homeowners and buyers maintain safe and structurally sound properties.

What Are Cavity Wall Ties?

Cavity wall ties are metal strips or rods used to connect the two layers of a cavity wall. Their main role is to keep the walls stable while preventing rainwater from travelling from the outer wall to the inner wall.

Why They Matter

  • They ensure the two walls act as a single, strong structure.
  • They reduce the risk of cracks, bulging, or collapse.

They play a vital role in keeping your property safe and secure.

Why Do Cavity Wall Ties Fail?

Common Causes of Wall Tie Problems

Over time, wall ties can deteriorate due to:

Corrosion
rusting of the metal, especially in older properties with mild steel ties.

Poor Installation
ties placed incorrectly or too few in number.

Property Age
homes built before stainless steel ties became standard are most at risk.

Exposure to Weather
coastal or damp environments accelerate deterioration.

The Risks of Ignoring Wall Tie Failure

If left unchecked, wall tie failure can cause:

  • Horizontal or stepped cracks in brickwork
  • Bulging or bowing external walls
  • Risk of partial or full wall collapse
  • Expensive repair costs if problems worsen

Frequently Asked Questions

How long do cavity wall ties last?

Modern stainless steel wall ties can last over 60 years. Older mild steel ties may fail much sooner, often after 20–30 years.

What are the signs of wall tie failure?

Cracks, bulging walls, and rust stains are common indicators. However, many issues are hidden and require a professional survey to confirm.

Can I repair cavity wall ties myself?

No, identifying and replacing wall ties requires specialist knowledge and equipment. A survey is essential before any work is carried out.

Do all homes need cavity wall tie surveys?

Not all. Surveys are most important for older properties, especially those built before stainless steel ties became standard.

How much does a cavity wall tie survey cost?

Costs vary depending on property size and location. Contact Surveying Cymru for a tailored quote.
