with cavity wall ties
What are cavity wall ties?
Cavity wall ties are important components that connect the inner and outer walls of buildings, making sure they remain securely fastened. These ties, typically made from metal, are embedded into the mortar during construction to hold the two wall skins together.
Modern cavity wall ties are often stainless steel, but older properties may have ties made from less durable materials, which are prone to corrosion over time.

Why do cavity wall ties need replacing?
Over time, older metal ties (especially those made from ferrous materials) can corrode, particularly in damp or coastal environments where salt in the air accelerates rusting. If left unchecked, the rust expands and puts pressure on the walls, leading to potential structural failures such as cracks or even complete collapse. Signs that your cavity wall ties may need replacing include:
Horizontal or stepped cracks in the brickwork
Bulging walls
Separation of the inner and outer walls
Neglecting this can lead to more serious problems, so quick replacement is key to maintaining the integrity of your property.

How are cavity wall ties repaired or replaced?
At Damp HQ, our process starts with a thorough inspection. One of our surveyors will use a small endoscope to inspect the cavity wall ties, assessing their condition. If the ties are corroded or damaged, they’ll be marked for replacement.
Our technicians carefully install new stainless steel ties, tailored to your property’s specific construction. After installation, any damage to the brickwork is repaired with matching mortar, leaving your home structurally safe and aesthetically intact.
Tips for maintaining structural health
Regular inspections: Think about getting regular inspections if your home is older or located in coastal areas prone to salt exposure.
Watch for signs: Pay attention to any unusual cracks or wall movement, as these may be early signs of tie failure.
Maintain your walls: Keep an eye on the condition of your external brickwork and make quick repairs to prevent water ingress, which accelerates
wall tie corrosion.
