What Is Structural Repair?

Structural repairs are essential to maintaining the safety and stability of any building.

Over time, all buildings are exposed to forces that can weaken their structure. Movement in the ground, water ingress, age-related deterioration. Poor construction practices can also lead to visible problems such as cracks, weakened lintels and compromised wall ties.

These issues are more than cosmetic. If left untreated, they can compromise the safety, stability, and long-term value of your property.

Structural repairs are the specialist processes used to restore strength and stability to buildings affected by such defects. From crack stitching and cavity wall tie replacement to lintel reinforcement, the right techniques ensure your property remains secure and compliant with building standards.

At Cannon Clarke, our team of experienced surveyors will diagnose the root cause of structural problems and apply tailored repair methods that deliver lasting results. By addressing defects early, we help homeowners, landlords, and developers avoid costly future repairs and safeguard their properties and investments.

Here’s an overview of some of the key methods we use for structural repairs:

Fixing Cracks In Walls

Cracks in walls are one of the most common signs of structural movement. While hairline cracks in plaster may be harmless, larger or recurring cracks in brickwork, render, or masonry can indicate an underlying structural problem that needs attention.

At Cannon Clarke, our surveyors investigate the cause of the cracking. Whether it’s foundation movement, wall tie failure, or stress from nearby building work, and will design and implement the right structural repair solution for your building. Sometimes we will recommend you seek advice from a structural surveyor who will advise the best course of action and repair schedule that Cannon Clarke can carry out.

 

Methods For Fixing Cracks In Walls

By addressing both the symptom (the crack itself) and the cause (movement or failure), we provide a long-term repair that restores both the appearance and strength of your walls.

Helical Bars

Helical bars are a versatile solution for reinforcing and stabilising masonry structures. These stainless steel bars are twisted into a helical shape, providing excellent tensile strength and flexibility.

 

Benefits of Helical Bars:

  • Versatility: Suitable for a variety of applications, including stitching cracks in walls and reinforcing weakened lintels.
  • Durability: Made from stainless steel, they are resistant to corrosion and provide long-lasting support.
  • Minimal Disruption: Installation is quick and causes minimal disruption to the existing structure.

Crack Stitching

Crack stitching is a method used to repair and stabilise cracked masonry. This technique involves inserting helical bars into the mortar joints across the crack, effectively stitching the masonry back together.

 

Benefits of Crack Stitching:

  • Effective Repair: Provides a permanent solution to cracked walls, restoring structural integrity.
  • Aesthetic Preservation: The repair is discreet, preserving the appearance of the building.
  • Cost-Effective: A less invasive and more affordable alternative to rebuilding damaged walls.

Lintel Reinforcement

Lintels are horizontal supports found above doors and windows. Over time, they can weaken due to factors such as age, moisture, and structural load. Lintel reinforcement involves strengthening these supports to prevent sagging and cracking.

 

Benefits of Lintel Reinforcement:

  • Enhanced Stability: Reinforces the structural integrity of openings, preventing further damage.
  • Prolonged Lifespan: Extends the life of existing lintels, avoiding the need for complete replacement.
  • Improved Safety: Ensures the safety of the building’s occupants by preventing potential structural failures.

Cavity Wall Tie Replacement

Cavity wall ties are metal components that connect the inner and outer leaves of a cavity wall. Over time, these ties can corrode, leading to structural instability. Replacing cavity wall ties is crucial to maintaining the integrity of cavity walls.

 

Benefits of Cavity Wall Tie Replacement:

  • Restored Stability: Ensures the inner and outer walls remain securely connected.
  • Corrosion Resistance: Modern wall ties are made from corrosion-resistant materials, providing long-term durability.
  • Preventative Maintenance: Replacing old, corroded ties prevents more extensive and costly repairs in the future.

Why Structural Repairs Are Important

Structural defects are more than just cosmetic concerns. Cracks, failing walls, or weakened lintels all point to underlying issues that, if ignored, can escalate into serious and costly problems.

  • Safety Risks: Structural weakness can compromise the stability of a property, posing risks to occupants and neighbouring buildings.
  • Reduced Property Value: Homes or commercial premises showing visible defects often lose market value and can be harder to sell.
  • Insurance Implications: Many insurers require structural problems to be professionally addressed before cover is offered or renewed.

In the UK, these risks are particularly relevant due to the country’s older housing stock and common construction methods. Many properties suffer from issues such as cavity wall tie failure, subsidence, damp-related weakening, or corroding concrete, all of which require professional repair to restore integrity.

By investing in timely structural repairs, you not only prevent further deterioration but also protect the long term safety, durability, and value of your property.

Our Approach to Structural Repairs

Every property is different and has its own unique challenges, which is why we assess every house individually and provide a bespoke solution. At Cannon Clarke, we combine technical expertise, industry accreditation, and proven systems to deliver structural repair solutions that stand the test of time.

1. Comprehensive Survey & Diagnosis

Our experienced surveyors carry out a detailed structural survey to identify the true cause of defects. We look beyond the visible cracks to assess ground conditions, load-bearing elements, and signs of movement, ensuring repairs address the root of the problem.

2. Tailored Repair Design

No two properties are alike. We design a bespoke repair plan based on your building’s condition, construction type, and intended use. Whether it’s crack stitching, cavity wall tie replacement, or lintel repairs, every solution is chosen for durability and compliance with UK building standards.

3. Expert Installation

Our trained technicians implement the repair plan using proven methods and high-quality materials. We work with precision and care, minimising disruption while restoring strength and stability to your property. We follow strict quality control processes to ensure every stage of the repair is completed to the highest standard.

4. Final Checks

Once repairs are complete, we carry out thorough checks and provide ongoing support where needed.

Our Process

Survey

We start by conducting a thorough survey of the space you want inspected. There's usually a fee for our initial consultation.

01

Scoping discussion

We collaborate with you to marry your objectives with our findings from the survey. We’ll discuss how you want to use the space when it’s finished and the best way of achieving your vision.

02

Design

Once we have the physical specifications, and your input on your requirements, we’ll design a system that works for you.

03

Approval

We’ll send you a specification, together with a report which explains the technical aspects. We’re happy to chat through this with you and make any changes you’ve identified.

04

Work begins

With an approved plan in place, we’ll get to work on the date we’ve agreed between us.
