Wall Tie Replacement in Thornbury (20)

Wall ties play a crucial role in keeping your home structurally sound — but over time, they can corrode, loosen, or fail altogether. If left unchecked, damaged wall ties can lead to cracks, bulging brickwork, and even structural instability.

If you suspect your cavity walls need attention, search for wall tie replacement services in Thornbury with Checkatrade for a commitment to quality and a job done right.

What is wall tie replacement?

Most modern cavity walls consist of two layers of brick or block with a gap (the cavity) between them.

Wall ties are metal connectors that hold these layers together, ensuring the wall acts as one solid structure.

Over time, older steel ties can rust or break, causing the outer wall to bow or crack.

Wall tie replacement involves identifying the failed ties, installing new stainless steel ones, and making good the mortar joints — restoring strength and stability to your property.
