A wall tie survey is a specialist inspection carried out to assess the condition of the wall ties within a property’s cavity walls. Wall ties are metal components that connect the outer brickwork leaf to the inner leaf of the wall, helping to maintain the structural stability of the building.

Over time, older wall ties can corrode and expand, placing pressure on the surrounding brickwork and mortar. This can lead to horizontal cracking, bulging walls and, in more advanced cases, structural movement. Many properties built throughout Liverpool and the surrounding areas between the 1920s and 1980s contain wall ties that may now be reaching the end of their service life.

At Northwest Wall Ties Ltd, our wall tie surveys are carried out independently and in accordance with BRE Digest 329 and BRE Digest 401 guidance. Using specialist equipment, including borescopes and metal detection technology, we inspect the existing wall ties within the cavity and assess their condition using recognised corrosion grading criteria.

Our detailed survey reports include:

• Borescope photographs of the inspected wall ties
• Photographs from the external visual inspection
• Cavity observations where accessible
• Identification of cracking, bulging or other signs associated with wall tie failure
• A clear explanation of our findings
• Recommendations for any remedial works where required

Unlike sales-led inspections, our recommendations are based solely on the condition of the wall ties and the evidence gathered during the survey. If remedial wall tie replacement is necessary, we explain the reasons clearly and provide transparent recommendations for the most appropriate solution.

If you own a property in Liverpool and have noticed horizontal cracking in brickwork, stepped cracking around openings, bulging walls, or have been advised by a mortgage lender or surveyor to obtain a wall tie inspection, a professional wall tie survey can provide the information needed to understand the condition of your cavity wall ties and any remedial action that may be required.

Liverpool has a large stock of traditional cavity wall properties, including Victorian, Edwardian and twentieth-century housing, many of which still contain their original wall ties. As these properties age, professional wall tie inspections can play an important role in identifying corrosion and helping homeowners, buyers and surveyors understand the condition of the building before remedial issues become more serious.

There are several reasons why a property owner, homebuyer, surveyor or mortgage lender may recommend a wall tie survey. The symptoms of wall tie failure can often resemble general building movement, settlement or structural cracking, making a specialist inspection essential to identify the underlying cause.

One of the most common signs of wall tie corrosion is horizontal cracking in the mortar joints. As corroding wall ties rust, they expand within the masonry, creating pressure that can force the brickwork apart and cause cracks to appear at regular intervals across the external walls.

Stepped cracking can also be an indicator of wall tie failure, particularly when it is accompanied by other symptoms such as bulging brickwork or horizontal cracking. These cracks typically follow the mortar joints in a stair-step pattern and are often found around corners, window openings and areas where the wall is under increased stress.

Another common warning sign is bulging or bowing brickwork. As wall ties deteriorate and lose their ability to securely connect the outer and inner leaves of the cavity wall, the external brickwork can begin to move outward. In more advanced cases, sections of wall may visibly bow or become unstable, requiring remedial wall tie replacement to restore structural integrity.

Property owners may also notice movement around windows and door openings. This can appear as cracking extending from the corners of windows and doors, distorted brickwork above lintels, widening joints or gaps forming around frames. Openings are naturally weaker areas within a wall and are often among the first locations where signs of wall tie failure become visible.

You may require a wall tie survey in Liverpool if:

• Horizontal cracking is visible in the mortar joints
• Stepped cracking is present within the brickwork
• External walls appear bowed, bulging or out of alignment
• Cracks are developing around windows and door openings
• Brickwork movement has been identified by a surveyor or mortgage lender
• The property was built between the 1920s and 1980s and retains its original wall ties
• You are purchasing an older cavity wall property and require reassurance regarding its condition
• Previous wall tie repairs have been carried out and an independent assessment is required

Liverpool has a large stock of cavity wall properties constructed throughout the Victorian, Edwardian and twentieth-century periods, many of which still contain original galvanised steel wall ties that may now be suffering from corrosion. Areas across Liverpool, Bootle, Crosby, Huyton, Prescot, Formby and the wider Merseyside region contain thousands of cavity wall properties where wall tie deterioration can become a concern as buildings age.

Where wall tie failure is suspected, a professional inspection can help determine the condition of the existing ties and whether remedial action is necessary. Early identification can often prevent more extensive structural defects and help property owners, buyers and lenders make informed decisions.

At Northwest Wall Ties Ltd, our wall tie surveys in Liverpool are carried out in accordance with BRE Digest guidance and include borescope inspections, cavity observations, photographic evidence and detailed reporting. This allows us to accurately assess the condition of the wall ties and provide clear, evidence-based recommendations for any remedial works that may be required.

Wall tie failure can develop gradually over many years, often without obvious signs during the early stages of corrosion. As the wall ties deteriorate, however, a number of characteristic defects can begin to appear within the brickwork. Recognising these warning signs early can help prevent more extensive damage and allow remedial works to be carried out before significant movement occurs.

One of the most common signs of wall tie failure is horizontal cracking in the mortar joints. Corroding wall ties expand as rust forms on the steel, creating pressure within the surrounding masonry. This expansion can cause cracks to develop along the bed joints, often at regular intervals across the external walls.

Stepped cracking is another defect frequently associated with wall tie corrosion. These cracks typically follow the mortar joints in a staircase pattern and may be found around window and door openings, corners of buildings or areas where the brickwork is under increased stress. While stepped cracking can have several causes, it is often investigated as part of a wall tie survey to determine whether corroded ties are contributing to the movement.

As corrosion progresses, the outer leaf of brickwork may begin to move independently from the inner leaf, leading to bulging or bowing walls. This is a more advanced symptom of wall tie failure and should be investigated promptly, as it can affect the stability and safety of the external wall.

Property owners may also notice cracking and movement around windows and door openings. Openings are naturally weaker points within a wall, making them more susceptible to movement caused by deteriorating wall ties. Cracks extending from window corners, widening joints, distorted brickwork or gaps forming around frames can all indicate that further investigation is required.

Other signs that may suggest wall tie failure include:

• Horizontal cracking within mortar joints
• Stepped cracking through brickwork
• Bulging or bowing external walls
• Cracks around windows and door openings
• Separation of brickwork at corners
• Loose, displaced or uneven brickwork
• Visible movement within external walls
• Defects highlighted by a mortgage valuation or building survey

Liverpool has a large number of cavity wall properties built throughout the twentieth century, many of which still contain their original wall ties. Older galvanised steel wall ties can become susceptible to corrosion over time, particularly where moisture has penetrated the cavity. This is commonly seen in traditional housing stock throughout Liverpool, Bootle, Crosby, Huyton, Prescot, Formby and the wider Merseyside area.

If you have noticed any of the signs above, a professional wall tie survey can determine the condition of the existing wall ties and establish whether remedial wall tie replacement is required. Identifying wall tie corrosion at an early stage can often prevent more extensive damage to the brickwork and help avoid unnecessary repair costs in the future.

At Northwest Wall Ties Ltd, our wall tie surveys in Liverpool include specialist cavity inspections, borescope photography, visual assessments and detailed reporting in accordance with BRE guidance. Our reports provide clear photographic evidence and independent recommendations, helping homeowners, buyers, surveyors and mortgage lenders understand the condition of the property’s wall ties and any remedial works that may be required.

One of the most common questions we are asked is, “How much does a wall tie survey cost in Liverpool?”

The cost of a wall tie survey can vary depending on the property location, property type and the level of inspection carried out. Across the North West, wall tie surveys typically cost between £250 and £400, with some specialist inspections costing even more.

At Northwest Wall Ties Ltd, we believe in transparent pricing and providing genuine value for our customers. For most properties within Liverpool, our wall tie survey fee is just £250.00, making us one of the most competitively priced specialist wall tie survey providers in the region.

Despite our competitive pricing, we do not compromise on the quality of our inspections or reporting. Our surveys are carried out in accordance with BRE Digest guidance and include detailed cavity wall investigations using specialist inspection equipment. Every report is designed to provide clear, evidence-based findings rather than sales-led recommendations.

Our Liverpool wall tie survey reports typically include:

• Borescope photographs of the inspected wall ties
• External inspection photographs
• Cavity observations where accessible
• Assessment of wall tie condition and corrosion grading
• Identification of defects associated with wall tie failure
• Clear recommendations for any remedial works where required

This means that while you receive a detailed independent survey report and professional assessment, the survey effectively becomes free if you proceed with the recommended works.

For homebuyers, this can be particularly valuable. Purchasing a property is often the biggest financial investment of your life, and understanding the condition of the wall ties before committing to the purchase is essential. In some cases, remedial wall tie replacement works can represent a significant expense. Having a detailed survey report and accompanying quotation allows you to make an informed decision and, where appropriate, use the findings during price negotiations with the seller before contracts are exchanged.

Many buyers find that the cost of a professional wall tie survey can be outweighed by the savings achieved through identifying defects before purchase. Even where no remedial works are required, the survey provides reassurance that the property’s cavity walls have been professionally inspected by a specialist.

Many property owners, buyers and surveyors are surprised by the level of detail included within our reports compared to other surveys available on the market. Our focus is on providing a thorough and independent assessment of the wall ties, helping clients make informed decisions about their property without unnecessary recommendations or pressure selling.

Liverpool has a large stock of cavity wall properties, including Victorian terraces, Edwardian homes and twentieth-century housing developments.

Many companies advertise “free wall tie surveys”, but in reality these are often quotation visits rather than comprehensive wall tie inspections.

A professional wall tie survey involves far more than simply visiting a property and looking for cracks in the brickwork. The surveyor must travel to and from the property, carry out a detailed visual inspection of the building, identify any signs of wall tie failure, undertake borescope inspections of the cavity wall, assess the condition of the existing wall ties and record photographic evidence throughout the inspection process.

Following the site visit, significant time is then spent reviewing the findings and preparing a detailed written report. This report must accurately assess the condition of the wall ties, identify any associated defects, explain the findings clearly and provide recommendations based on recognised industry guidance.

At Northwest Wall Ties Ltd, our Liverpool wall tie surveys are carried out in accordance with BRE Digest guidance and are designed to provide genuine value to homeowners, buyers, surveyors and mortgage lenders. When you consider the travel time, specialist equipment, an experienced surveyor’s time on site and the hours required to produce a professional report, it would be impossible for us to maintain this standard whilst offering completely free surveys.

In many cases, what is advertised as a “free wall tie survey” is actually a free site inspection undertaken by a company whose primary objective is to secure remedial work. Whilst these visits can identify obvious signs of wall tie failure, they do not always provide the level of investigation or reporting required when purchasing a property, satisfying a lender’s requirements or fully understanding the extent of any defects.

A professional wall tie survey can influence decisions worth thousands of pounds. For homebuyers in Liverpool, the findings may be used to renegotiate the purchase price before contracts are exchanged. For homeowners, the report can help determine the most appropriate remedial solution. For mortgage lenders and surveyors, the report provides documented evidence of the wall tie condition and any recommended works.

Importantly, remedial wall tie replacement is not always as simple as installing new wall ties. Depending on the type and condition of the existing ties, additional remedial measures may be required. Existing wall ties may need to be isolated to prevent further expansion, and in some cases certain tie types may need to be completely removed. Simply installing a new tie system without addressing the existing defective ties may not always provide a complete long-term solution.

This is why a detailed survey is so important. The purpose of a professional wall tie survey is not simply to identify whether new wall ties are required, but to establish the condition of the wall, determine the appropriate remedial specification and provide clear, evidence-based recommendations.

Liverpool has a large stock of traditional cavity wall properties, including Victorian terraces, Edwardian homes and twentieth-century housing. Many of these properties still contain their original wall ties, making accurate diagnosis essential before any remedial works are specified. A professional survey ensures that any recommendations are based on the actual condition of the wall ties rather than assumptions made during a brief site visit.

Where remedial works are recommended and you choose Northwest Wall Ties Ltd to carry out the repairs, the full survey fee is deducted from the cost of the works. This means you still benefit from a comprehensive independent survey and report, while effectively receiving the survey free of charge if you proceed with the recommended remedial work.
