Wall Tie Replacements in Harrow (174)

Wall ties are a key component used in cavity walls. During construction, wall ties are added to join both your external and internal walls together. They’re usually made from metal and attached to the mortar between bricks that make up the walls of your home.

The purpose of wall ties is to add extra strength and stability to your property.

Originally, galvanised steel wall ties were very popular, however these ties are vulnerable to corrosion after 15-20 years. Now, other types of metal like stainless steel are used. This reduces the risk of damage from water and wall ties are now designed to last over 50 years.

If your home was built before 1980 the chances are your wall ties were made using galvanised steel. This material can corrode, causing the wall ties to fail. Homes built later than 1980 may have issues if the wall ties were installed incorrectly.

For example if the ties were spaced badly or the wrong sized ties were used.

Usually, this will be done by a professional to prevent damaging the cavity walls of your home. Using a metal detector, the wall tie specialist will locate the metal wall ties in your walls. They’ll then drill a small hole before using an endoscope to examine the condition of your wall ties.

It’s difficult to know what condition your wall ties are in without looking at them directly. However, there are a few telltale signs that wall ties are failing. If you have cavity walls, look out for the following issues:

• External wall cracks: Often seen in mortar joints

• Internal wall cracks: Often seen between your walls and ceiling

• Wall bulging: Your external wall appears to be bulging outwards

Getting your wall ties replaced is essential if they become corroded or damaged. If you choose not to replace your wall ties, you risk causing structural damage to your home.

Thankfully, the average wall tie replacement cost is not too high. You can expect to pay £5-£8 for each tie or a wall tie replacement cost of £40 per m2. You can find more information in our wall tie replacement cost guide.
