A wall tie survey is a specialist inspection used to assess the condition of metal wall ties within cavity walls. These ties secure the external brickwork to the inner wall, helping the structure perform as a single unit.

Over time, wall ties can corrode and expand, causing pressure within the masonry. Common signs of wall tie failure include horizontal cracking, bulging brickwork, lifting mortar joints, and structural movement.

Many properties across Bolton, particularly those built between the 1920s and 1980s, can be more susceptible to wall tie deterioration due to the use of mild steel wall ties.

Northwest Wall Ties Ltd provides independent wall tie surveys across Bolton using specialist detection equipment and borescope technology to locate and inspect wall ties within the cavity. Our inspections follow recognised BRE guidance, including BRE Digest 329 and BRE Digest 401.

Our wall tie survey reports typically include:

• Internal and external visual inspections
• Wall tie identification and corrosion assessments
• Borescope images and cavity observations
• Photographic evidence of defects
• Independent recommendations based on findings
• Quotations for remedial works where required

Wall tie surveys are commonly recommended for homeowners and property buyers where cracking, movement, or potential wall tie failure has been identified, helping to establish repair requirements before issues become more serious.

A wall tie survey in Bolton is recommended when a property shows signs of wall tie failure, external wall movement, or brickwork defects that could affect structural stability. Common warning signs include horizontal cracking in brickwork, bulging walls, stepped cracks, rust staining, or separation between external masonry and internal walls. Older properties across Bolton, particularly homes built with cavity wall construction, can experience wall tie deterioration over time due to corrosion and age. A professional wall tie survey in Bolton helps identify hidden issues early, assess the condition of existing wall ties, and determine whether wall tie replacement or remedial work is required before structural damage becomes more severe.

Wall tie failure in Bolton homes can develop gradually and often creates visible warning signs that indicate underlying structural concerns within cavity wall construction. Common symptoms include horizontal cracks in brickwork, stepped cracking around windows and doors, bulging external walls, and rust staining appearing on masonry surfaces. Some homeowners may also notice separation between internal and external walls or movement affecting the property’s structure over time. Older properties in Bolton can be more susceptible to wall tie corrosion and deterioration due to age and environmental exposure. A professional wall tie survey in Bolton can identify these issues early and determine whether wall tie replacement or remedial repairs are necessary.

Wall tie failure often develops slowly over many years and may not show obvious symptoms until corrosion is well advanced. As wall ties deteriorate, they can cause a range of visible defects in brickwork that should be investigated through a professional wall tie survey in Bolton.

One of the earliest indicators is horizontal cracking in mortar joints. This is caused by expanding rust on corroded steel wall ties, which places pressure on surrounding brickwork. Stepped cracking is also common, particularly around windows, doors and corners, where structural stress is highest. These patterns are frequently assessed during wall tie inspections to determine the underlying cause.

In more advanced cases, bulging or bowing external walls may occur as the outer leaf begins to separate from the inner leaf. This can indicate significant wall tie failure and should be inspected promptly. Additional warning signs include cracking around window and door openings, displaced brickwork, and visible movement in external walls.

Common signs of wall tie failure include:

• Horizontal cracking in mortar joints
• Stepped cracking in brickwork
• Bulging or bowing walls
• Cracks around windows and doors
• Separation at building corners
• Loose or uneven brickwork
• General wall movement or distortion

Many properties in Bolton, including Victorian terraces, interwar housing and post-war cavity wall homes, still contain original galvanised steel wall ties.

Over time, these can corrode due to moisture penetration within the cavity, particularly across areas such as Westhoughton, Horwich, Farnworth, Little Lever and Blackrod.

If these issues are present, a wall tie survey in Bolton can confirm the extent of deterioration and whether wall tie replacement is required. Early diagnosis helps prevent further structural damage and reduces long-term repair costs.

Many companies advertise “free wall tie surveys”, however these are usually limited quotation visits rather than full, independent wall tie inspections in Bolton. In most cases, a so-called free visit is designed primarily to generate repair work rather than provide a detailed structural assessment. A professional wall tie survey in Bolton is a far more in-depth process, requiring time, technical knowledge, and specialist equipment to properly assess the condition of cavity wall construction in local properties.

A proper wall tie survey in Bolton involves a detailed inspection of the property both externally and internally where access allows, identifying potential signs of wall tie failure such as cracking, bulging masonry, or rust staining. Where necessary, borescope equipment is used to inspect the cavity wall and assess the condition of existing wall ties hidden within the structure. Throughout the inspection, photographic evidence is recorded to support findings and ensure accuracy. Once the site work is complete, a full written report is produced in line with BRE guidance, assessing the condition of wall ties and clearly outlining any defects or required remedial works. This level of detail is essential for Bolton homeowners, buyers, and surveyors who need reliable information before making decisions on a property.
