Insite Fixings was formed in order to provide a specialist service in the field of wall tie replacement which, according to the Building Research Establishment is likely to affect in excess of 10 million homes in the United Kingdom.
Wall tie corrosion can affect buildings as recent as 1981, leading to serious issues like horizontal cracking, bulging masonry, and, in high winds, the potential collapse of the outer brickwork leaf. Early stabilisation is crucial for safety and to avoid costly demolition and reconstruction.
Corrosion causes ties to expand up to 7 times their original thickness, leading to horizontal cracks and wall bulging.
Our Professional Process
Detailed Inspection: Insite uses metal detection equipment and fibre optic endoscopes to locate and inspect existing ties between the walls, allowing for an accurate condition assessment.
Tailored Replacement: We select the most suitable, precision-engineered corrosion-free stainless steel replacement ties (mechanical, resin, or combination) based on the inspection and site conditions.
Expert Installation: New ties are installed to the correct torque or set in specially selected resins. Corroded cast iron ties are removed or isolated to prevent further damage.
Finishing: Disturbed brickwork is neatly made good using colour-matched mortar. We also offer additional structural repairs, including Lateral Restraints and Helical products, to stabilise walls, cracks, and lintels.
We provide a full, certified 25-YEAR GUARANTEE on all remedial works, giving you complete long-term assurance and peace of mind regarding the structural integrity of your property.
As true specialists, we use advanced detection equipment (metal detectors and fibre optic endoscopes) for accurate diagnosis. We only install corrosion-free, precision-engineered stainless steel ties (mechanical, resin, or combination) specifically suited to your building’s condition.
Our service includes not only the installation of new wall ties but also the expert removal or isolation of old, corroding ties, structural repairs (like lateral restraints), and matching mortar to ensure a seamless finish, protecting both the structure and the aesthetics of your property.

Look out for horizontal step cracks in brickwork, bulging or bowing walls, and mortar separation. Since wall tie corrosion is often accelerated by moisture, these signs may also appear alongside issues like rising damp or localised mould issues, indicating a potential threat to your property’s structural integrity.
Insite Southern utilizes precision mechanical wall tie installation with stainless steel ties. These advanced, corrosion-free ties provide a flexible but firm anchorage between the inner and outer walls, ensuring a permanent structural safeguard with minimal disruption to your existing masonry.
The average cost is based on a detailed on-site inspection and is influenced by the property type and size, the number of ties needed, wall access (e.g., scaffolding required), and the extent of the existing corrosion. Investing in our expert solution ensures honest pricing and a guaranteed long-term value against future structural failure.
Timely replacement with high-performance ties prevents the outer and inner walls from separating, stopping horizontal cracking and potential collapse. By reinforcing the structural core, Insite Southern’s service avoids far more extensive and expensive remedies, with all work backed by our 25-YEAR CERTIFICATE OF GUARANTEE.
