If you own a property with cavity walls which is common in houses built from the 1920s onwards then cavity wall ties are a vital part of your home’s structural stability. While they’re not something you can see, they play a crucial role behind the scenes. But like any hidden component, they can deteriorate over time and cause serious problems if left unchecked.
So, what exactly are wall ties, and how do you know if yours are in good condition?
What Are Cavity Wall Ties?
Cavity wall ties are metal components built into the wall structure during construction. They connect the outer and inner walls (also called leaves) of a cavity wall, keeping them securely bonded and aligned.
Without functioning wall ties, the two layers of brickwork can start to move independently which can eventually lead to visible cracks, bulging walls, and even structural failure.
What Happens When Wall Ties Fail?
Over time, cavity wall ties can corrode, especially in older properties or homes located near the coast where salt-laden air accelerates rusting. Common issues caused by failing wall ties include:
- Horizontal cracking in the mortar joints, often visible from the outside.
- Bulging or bowing brickwork, as the outer wall becomes unstable.
- Cracks around window or door openings.
- In severe cases, partial wall collapse.
Unfortunately, these problems often go unnoticed until the damage is well advanced and costly to repair.
How Can You Check the Condition of Your Wall Ties?
The best way to assess the health of your wall ties is by arranging a professional wall tie survey. During a survey, a trained specialist will inspect the walls using a borescope (a small camera inserted through drilled holes), allowing them to view the condition of the ties without causing unnecessary damage to your property.
The survey will determine:
- Whether your existing wall ties are sound or showing signs of corrosion.
- If there is an appropriate number of ties in place.
- Whether replacement or remedial work is needed.
We carry out thorough wall tie surveys using the latest equipment and techniques. If remedial work is required, we’ll recommend the best course of action to restore the structural integrity of your property.
Why Choose a Specialist?
Cavity wall tie issues are not always easy to spot, and misdiagnosis can lead to unnecessary or ineffective repairs. That’s why it’s essential to instruct a qualified specialist to carry out your survey and any follow-up work.
We’re proud to be members of the Wall Tie Installers Federation (WTIF) an industry recognised body that ensures high standards in wall tie inspections and replacements. As members, we follow strict codes of practice and provide work that meets or exceeds industry expectations.
Peace of Mind Starts with a Survey
Whether you’ve noticed signs of cracking or simply want peace of mind about the condition of your cavity walls, a wall tie survey is a smart investment. It’s quick, non-invasive, and could save you from major structural issues and costly repairs in the future.
