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.

Wall ties can deteriorate over time for a number of reasons, including:

• Corrosion & rust – Older metal wall ties can rust, expand and lose their strength over time.
• Black ash mortar – Common in older budlings, black ash mortar can contain impurities that contribute to accelerated corrosion of metal wall ties.
• Coastal locations – Salt-laden air and increased moisture can speed up corrosion, particularly in properties close to the coast.
• Age of the property – Original wall ties may simply have reached the end of their service life.
• Moisture penetration – Persistent dampness within the cavity can increase the risk of corrosion.
• Poor installation – Incorrectly installed or unsuitable wall ties may fail prematurely.
• Unsuitable original ties – Some older types of wall ties are more susceptible to corrosion than modern replacement systems.

Replacing deteriorated wall ties helps restore the connection between the inner and outer walls and provides a reliable, long-term solution.

When existing wall ties have failed, are missing or are no longer suitable, we provide a range of specialist remedial wall tie systems to restore the connection between the inner and outer leaves of the cavity wall.

The most suitable system depends on the construction, condition and type of masonry. Our options include:

• Mechanical Neoprene Ties – Secure expansion-based fixings suitable for many standard cavity walls.
• Helical Drive Ties – Hammer-driven ties providing a fast and secure mechanical fixing.
• Mechanical Brass Ties – Expansion ties offering reliable load transfer and good corrosion resistance.
• Resin-Bonded Ties – Chemically bonded ties used where mechanical fixing is unsuitable or a strong resin bond is required.
• Grout Sock Ties – Grout-filled mesh sleeves suitable for hollow, perforated or irregular masonry.
• Cementitious (CEM) Ties – Grout-fixed ties providing a strong and durable connection.

We select the correct system based on the specific construction and condition of your property.

Wall tie replacement normally starts with an initial survey. This allows us to assess the condition of the existing ties, identify the cause of deterioration and determine what remedial action is required. We can then select the most suitable replacement wall tie for the masonry and construction of your property.

Where possible, we install the new wall ties through the existing mortar joints. This provides a more discreet finish and helps minimise any visible disturbance to the brickwork.

However, if the mortar joints are unsuitable or we cannot achieve a strong enough fixing within them, we may need to drill through the bricks. We use a 10mm masonry bit and dustless drilling equipment to minimise dust and mess, helping to protect your property and neighbouring properties.

Once installed, the holes are filled and finished as discreetly as possible. Over time, the repair will naturally blend into the surrounding brickwork and become difficult to notice.

Every property is different, so there is no single wall tie system suitable for every installation. Our specialist surveyors assess the construction, masonry, mortar, age and condition of your property to determine the correct wall tie, length, spacing and fixing method.

Where required, pull-out testing can also be carried out to confirm the strength of the masonry and ensure the chosen system is suitable.

We only use premium-grade stainless steel wall ties, selected for long-term durability and corrosion resistance. This is particularly important in properties with aggressive materials such as black ash mortar or those exposed to coastal conditions.

As we provide a 25-year guarantee, we believe in using quality materials and carrying out every installation correctly, without cutting corners.

Wall ties can look like a straightforward job, and it can be tempting to save money by finding a local builder or following advice online. However, we come across this situation frequently, and in every case we have surveyed, the previous wall tie installation has failed to meet the required British Standards.

When there is no certified installer, guarantee or documentation, we cannot confirm who installed the ties, when they were installed, or whether the correct installation procedures were followed. When the property is being sold or re-mortgaged, this can become a major issue.

In every case we have encountered where the original installation could not be verified, new wall ties have ultimately been recommended so that the work can be properly certified and the sale can proceed. This means the homeowner ends up paying for the work twice, with additional drilling and double the number of holes in the property.

Although using a builder you know or doing it yourself may seem cheaper initially, it can end up costing more in the long run. Using a specialist from the beginning ensures the work is carried out correctly, to the required standards, with the appropriate certification and guarantee.
