A structural repair is a repair carried out to restore the strength, stability, and safety of a building where structural movement or deterioration has occurred. Common causes include wall tie failure, subsidence, cracked masonry, failed lintels, and other structural defects that can affect the integrity of a property.

Structural problems often begin with visible signs such as cracking, bulging walls, or movement. If left untreated, these defects can worsen over time, resulting in more extensive and costly repairs.

At Northwest Wall Ties Ltd, we specialise in identifying the cause of structural defects and providing effective, long-lasting repair solutions. Our experienced surveyors assess each property individually and recommend the most appropriate remedial works to restore structural integrity while ensuring all repairs are completed to current British Standards.

Not every structural defect requires the same repair solution. Where a repair falls outside our scope of work, we work closely with a trusted network of experienced structural engineers who can provide specialist advice and design suitable remedial solutions. This ensures every customer receives the correct recommendation and the most appropriate repair for their property

Signs of structural movement can often indicate underlying issues affecting the stability and safety of a property. Common warning signs include stepped cracking in brickwork, horizontal or vertical cracking, bulging masonry, failed wall ties, lintel failure, and general masonry movement. These defects can develop gradually over time and may become more severe if left unaddressed.

Structural movement can be caused by a range of factors, including corroded wall ties, foundation settlement, thermal expansion, moisture ingress, or deterioration of structural supports such as lintels. Identifying the cause early is essential to prevent further damage and ensure the correct remedial action is taken. Our inspections help assess the severity of movement and provide clear, honest recommendations based on the condition of the property.

We provide specialist structural remedial repairs across the Northwest using proven reinforcement systems designed to restore stability and prevent further structural movement. All repairs are professionally installed using industry-recognised methods and are backed by long-term 25-year guarantees for complete peace of mind.

Our services include masonry crack stitching, helical bar reinforcement, lintel repairs, masonry stabilisation, and structural movement repairs. These systems are designed to strengthen damaged masonry, redistribute structural loads, and provide effective long-term solutions for cracking and movement-related defects. Every repair is tailored to the condition of the property to ensure the most appropriate and reliable remedial approach is used.

Masonry crack stitching is a permanent structural repair method used to strengthen and stabilise cracked brickwork or stonework. The process involves cutting slots into the mortar joints across the crack and installing high-strength stainless steel reinforcing bars, which are securely bonded in place using specialist grout.

Unlike simply filling or repointing a crack, crack stitching reinforces the wall, helps redistribute structural loads and reduces the risk of the crack reopening, while preserving the original appearance of the masonry.

MASONRY CRACK STITCHING IS COMMONLY USED TO REPAIR:

• Cracked brick walls
• Stone masonry
• Structural movement cracks
• Lintel failure cracks
• Subsidence-related cracking once movement has been addressed
• Cracks around doors and windows

BENEFITS OF MASONRY CRACK STITCHING

• Restores structural integrity
• Helps prevent cracks from widening or reappearing
• Minimal disruption to existing brickwork
• Cost-effective alternative to rebuilding
• Long-lasting, corrosion-resistant stainless steel reinforcement
• Virtually invisible once the repair has been repointed

Lateral restraint systems are used to secure external walls to internal floors and roof structures, helping prevent walls from leaning, bowing or separating from the building.

Movement, ageing, roof spread or inadequate original construction can cause walls to become unstable. Lateral restraint straps and bow ties provide a strong mechanical connection to improve stability and help prevent further movement.

LATERAL RESTRAINT STRAPS

Heavy-duty galvanised or stainless steel straps secure external walls to floor joists or roof structures. They are commonly used for bowing walls, roof spread and walls that have become detached from the internal structure.

LATERAL RESTRAINT BOW TIES

Stainless steel bow ties provide additional restraint to bowing or unstable masonry walls by connecting the external wall to suitable internal structural elements.

OUR LATERAL RESTRAINT SERVICE

We assess the cause of the movement before recommending the most suitable solution. Whether straps, bow ties or a combination are required, we provide durable structural repairs designed to improve stability and minimise disruption.

Having wall ties replaced is a specialist job, and the installation process matters just as much as the wall ties themselves.

At Northwest Wall Ties, we follow a clear, structured process from the initial survey through to installation, testing, finishing and final handover.

Every property is assessed individually, with the appropriate wall tie system and installation method selected based on the condition and construction of the masonry. We use specialist equipment, controlled drilling methods and industry-standard installation practices to ensure the work is carried out correctly, safely and with minimal disruption to your property.
