So, what are helical bar lintels and how do they work?

Helical bar lintel reinforcement is a modern structural repair method used to strengthen or replace the function of a failing lintel without the need for full removal or major rebuilding. High-strength stainless steel helical bars are installed into the mortar joints above doors and windows, then bonded with a specialised grout to create a reinforced beam within the existing brickwork.

This method redistributes the load above the opening, stabilising the structure and preventing further movement or cracking—much like traditional lintels, but with far less disruption.

But helical bar lintels aren’t just an alternative—they offer a range of practical advantages over conventional lintel replacement:

Minimal Disruption:

Unlike traditional lintel replacement, which often involves removing brickwork and installing temporary supports, helical bar systems can be installed with minimal disturbance to the structure and surrounding areas.

Cost-Effective Solution:

Because there is no need for extensive demolition or rebuilding, helical bar lintel reinforcement is typically more affordable while still delivering excellent structural performance.

Strength and Load Distribution:

The helical bars act as a reinforced beam, effectively spreading loads across the opening and restoring stability to weakened or failed lintels.

Preserves Existing Brickwork:

This method allows you to retain the original appearance of your property, making it ideal for older buildings or where matching brickwork would be difficult.

Versatile Application:

Suitable for a wide range of properties, helical bar lintels can be used on domestic homes, extensions, and older structures where traditional methods may be more invasive.

Long-Term Durability:

Manufactured from high-quality stainless steel, helical bars are resistant to corrosion and designed to provide long-lasting structural support.

How Do Helical Bar Lintels Compare to Traditional Lintels?

Traditional lintel replacement typically involves removing brickwork above an opening, installing a new steel or concrete lintel, and rebuilding the surrounding area. While effective, this process can be time-consuming, disruptive, and more costly.

Helical bar lintel reinforcement, on the other hand:

• Requires far less removal of existing materials

• Can often be completed more quickly

• Reduces labour and overall cost

• Minimises mess and disruption

• Maintains the original look of the property

While full lintel replacement is sometimes necessary in cases of severe structural failure, helical bar systems are an excellent solution for many situations where reinforcement and stabilisation are required.

Don’t ignore cracks forming above doors and windows.

These are often early signs of lintel failure, and addressing them quickly can prevent more serious structural issues developing over time.
