If you require a professional wall tie survey in Preston, Northwest Wall Ties Ltd provides independent wall tie inspections, detailed reports, and expert advice for homeowners, property buyers, surveyors, and mortgage lenders throughout Preston and the surrounding areas.

Our wall tie surveys are designed to assess the condition of cavity wall ties and identify any signs of corrosion, deterioration, or structural movement that may affect the stability of a property’s external masonry. Using specialist wall tie detection equipment and borescope camera inspections, we can investigate the condition of wall ties within cavity walls and provide clear, evidence-based recommendations.

Many properties across Preston, including traditional terraces, semi-detached homes, interwar housing, and post-war developments, were constructed using mild steel wall ties. As these ties age, they can become susceptible to corrosion, potentially leading to horizontal cracking, bulging brickwork, and other signs of wall tie failure.

Our Preston wall tie surveys are carried out in accordance with BRE Digest 329 and BRE Digest 401 guidance and include photographic evidence, cavity observations, corrosion assessments, and comprehensive reporting.

Whether you have noticed signs of possible wall tie failure, have been advised by a surveyor to obtain a specialist inspection, or simply require reassurance regarding the condition of a property before purchase, our surveys provide the information needed to make informed decisions.

As specialists in wall tie inspections and replacement, Northwest Wall Ties Ltd regularly carries out wall tie surveys throughout Preston, Fulwood, Penwortham, Bamber Bridge, Longridge, Leyland, Walton-le-Dale, and the surrounding Lancashire area.

Many property owners only become aware of potential wall tie problems after visible defects begin to appear within the brickwork. Because the symptoms of wall tie corrosion can often resemble general settlement or structural movement, a specialist wall tie survey is often required to determine the underlying cause.

Some of the most common signs that may indicate the need for a wall tie survey include:

Horizontal Cracking

Horizontal cracking along mortar joints is one of the most recognised symptoms of wall tie corrosion. As older steel wall ties corrode, they expand within the masonry, placing pressure on the surrounding brickwork and causing cracks to develop along the bed joints.

Bulging or Bowing Brickwork

Where wall ties have significantly deteriorated, the outer leaf of brickwork may begin to move outward. This can result in walls appearing bowed, uneven, or out of alignment and should be investigated as soon as possible.

Stepped Cracking

Cracks following the mortar joints in a stair-step pattern can sometimes be associated with wall tie failure, particularly when found alongside horizontal cracking or bulging masonry.

Cracking Around Windows and Doors

Openings within a wall are naturally weaker areas of construction. Cracks developing from window or door corners, widening joints, or movement around frames can sometimes indicate wall tie-related movement.

Surveyor or Mortgage Lender Recommendations

Many wall tie surveys are commissioned following recommendations from homebuyer surveys, structural reports, or mortgage valuations. Where cracking or movement has been identified, lenders may request a specialist wall tie inspection before proceeding.

Older Cavity Wall Properties

Many properties throughout Preston were constructed between the 1920s and 1980s using mild steel wall ties. As these properties age, the likelihood of corrosion-related deterioration can increase, making professional inspection beneficial where concerns exist.

If you have noticed any of these symptoms at your property, a professional wall tie survey can help determine whether wall tie deterioration is present and whether any remedial works may be required.

Our wall tie surveys in Preston are designed to provide a comprehensive assessment of the condition of a property’s cavity wall ties, helping homeowners, property buyers, surveyors, and mortgage lenders make informed decisions based on clear, evidence-based findings.

Using specialist wall tie detection equipment and borescope camera technology, we inspect the wall ties within the cavity and assess their condition in accordance with BRE Digest 329 and BRE Digest 401 guidance.

Every Preston wall tie survey includes:

External Visual Inspection

A detailed inspection of the accessible elevations is carried out to identify any signs commonly associated with wall tie deterioration, including horizontal cracking, stepped cracking, bulging brickwork, displacement, and other masonry defects.

Wall Tie Detection and Identification

Specialist metal detection equipment is used to locate wall ties within the cavity walls. This allows us to determine wall tie spacing, positioning, and identify areas requiring further investigation.

Borescope Camera Inspection

Small inspection holes are drilled where necessary to allow a borescope camera to access the cavity. This enables direct examination of the wall ties and surrounding cavity conditions without causing unnecessary disruption to the property.

Corrosion Assessment

The condition of the wall ties is assessed using recognised BRE corrosion grading criteria. This helps determine whether the ties remain serviceable, require monitoring, or have deteriorated to a level where remedial action should be considered.

Cavity Observations

Where access permits, observations are made regarding cavity width, construction type, moisture conditions, debris, and any factors that may contribute to wall tie deterioration.

Photographic Evidence

Our reports include borescope photographs of the inspected wall ties together with photographs from the external inspection. This provides a clear visual record of the findings and supports the recommendations made within the report.

Detailed Written Report

Following the inspection, a comprehensive report is produced outlining the survey findings, corrosion assessments, photographs, and recommendations. The report is written in clear, straightforward language to ensure clients fully understand the condition of the wall ties and any issues identified.

Remedial Recommendations and Quotations

Where remedial works are considered necessary, the report will include clear recommendations together with a detailed quotation for the proposed repairs. Should you choose Northwest Wall Ties Ltd to carry out the recommended wall tie replacement works, the cost of the initial survey will be deducted from the quotation.

Our independent approach ensures that recommendations are based on the condition of the wall ties and supporting evidence gathered during the inspection, providing complete transparency and confidence in the findings.

Unlike sales-driven inspections, our reports are supported by photographic evidence, cavity observations, and clear explanations of our findings. This ensures complete transparency and gives clients confidence that recommendations are based on the condition of the wall ties rather than a predetermined repair solution.

Where remedial works are recommended, a detailed quotation can be included within the report. Should the recommended wall tie replacement works proceed, the cost of the initial survey is deducted from the quotation, providing additional value and peace of mind.

With extensive experience inspecting cavity wall properties throughout Preston, our surveys provide clear, professional, and evidence-based assessments that help clients make informed decisions regarding their property.

When searching for a wall tie survey in Preston, you may come across companies offering “free surveys.” In many cases, these are not comprehensive wall tie inspections but initial site visits intended to generate quotations for remedial work.

A professional wall tie survey involves a detailed investigation of the property’s cavity wall construction. This includes a thorough visual inspection, specialist wall tie detection, borescope camera investigations, cavity observations, photographic recording, and an assessment of the condition of the existing wall ties using recognised industry guidance.

Following the inspection, the findings must be carefully reviewed and compiled into a detailed written report. The report should explain the condition of the wall ties, identify any associated defects, assess corrosion levels, and provide recommendations based on the evidence gathered during the survey.

At Northwest Wall Ties Ltd, our Preston wall tie surveys are carried out in accordance with BRE Digest 329 and BRE Digest 401 guidance. We believe clients should receive a thorough and independent assessment that provides genuine value, whether they are purchasing a property, responding to a surveyor’s recommendation, or investigating signs of possible wall tie failure.

Many cavity wall properties throughout Preston, Fulwood, Penwortham, Bamber Bridge, Walton-le-Dale and the surrounding areas were constructed using mild steel wall ties that may now be experiencing age-related deterioration. Identifying the condition of these wall ties requires specialist equipment, technical knowledge, and sufficient time to investigate and report accurately.

A wall tie survey can play an important role in property transactions and maintenance planning. For homebuyers, it can help identify potential repair liabilities before contracts are exchanged. For homeowners, it provides clarity regarding the condition of the structure and whether remedial works are necessary. For surveyors and mortgage lenders, it provides documented evidence to support informed decision-making.

Where replacement wall ties are recommended, it is important to understand that the solution may involve more than simply installing new ties. Existing corroded wall ties may also require isolation to prevent ongoing expansion forces from affecting the surrounding masonry. A detailed survey helps ensure that any recommendations are appropriate for the property’s specific construction and condition.

To provide additional value, where remedial wall tie replacement works are recommended and subsequently instructed, the full cost of the survey is deducted from the repair quotation. This allows clients to benefit from a comprehensive wall tie survey and professional report while avoiding duplication of costs should remedial works proceed.
