Remedial wall ties — also referred to as wall tie replacements or lateral restraints — are stainless-steel fixings drilled through the outer brick leaf of a cavity wall, across the cavity, and bonded into the inner leaf. They physically reconnect the two leaves of the wall, replacing the original metal ties that have corroded and failed.

Here's what most homeowners don't realise: the brickwork is usually fine. It's the invisible ties behind it that have failed. Those original ties — mild steel or galvanised wire in older homes — rust, expand, and eventually snap. Once enough ties go, the outer wall has nothing holding it in place and it starts to show signs of leaning and bowing outward under its own weight.

Remedial wall ties reconnect what time has taken away. The wall is stabilised without knocking it down, without rebuilding, and without any visible fixings on the face of the brickwork. Done in 1–2 days.

The primary causes of wall tie failure include corrosion from exposure to moisture and water, disconnection caused by subsidence, and damage from expanding brickwork. When enough ties fail, the outer leaf disconnects from the inner structure and starts moving independently — leaning, bowing, or separating from window frames and the roofline.

Look for gaps opening around windows, horizontal cracking along mortar bed joints, or the outer wall visibly pulling away from the roofline. Remedial wall ties reconnect those leaves before the damage progresses further. Once installed, the lean is arrested, the wall is stable, and the repair is invisible behind colour-matched mortar.
