Restoring Integrity to Brick, Block, and Stone Façades

Masonry façades are built to last but they’re not immune to wear, weather, and structural movement over time. From cracked mortar and water ingress to structural concerns and cosmetic damage, CPR delivers precise, scaffold-free repairs that extend the life of your façade and protect your asset.

Common Masonry Repairs

Repointing

Repointing involves the careful removal and replacement of deteriorated mortar between masonry units (typically brick or stone). This restores structural integrity, prevents water ingress, and improves the overall appearance of the façade. Our rope-access technicians carry out detailed repointing work, ensuring that joints are cleaned, matched, and finished to a high standard—without the need for scaffolding.

When is repointing needed?

  • Cracked, crumbling, or missing mortar
  • Water staining, salt deposits (efflorescence), or dampness
  • Loose or bowing bricks
  • Uneven brickwork or discolouration

Cavity Flashing Replacement

Cavity flashings are critical for redirecting water away from internal wall cavities and out of the building. If improperly installed, blocked, or deteriorated, they can lead to internal water damage and mould. We replace faulty cavity flashings with durable, modem materials while preserving the external finish of the wall, ensuring proper weep hole function and weatherproofing.

Indicators of failed cavity flashing:

  • Persistent internal damp or staining
  • Water pooling at the base of internal walls
  • Rusting lintels or corrosion near wall openings

Brick Stitching (Crack Stitching)

Brick stitching is a structural repair technique used to stabilise cracked masonry. It involves inserting stainless Steel rods into horizontal bed joints across cracks, binding the wall back together without full rebuild. This is a discreet, effective method to stop further movement and restore wall strength.

When to consider brick stitching:

  • Diagonal or stepped cracks in brick walls
  • Visible cracking around windows, doors, or wall corners
  • Bowing or bulging areas of masonry

Project Highlight:

A mixed-use residential and hotel complex suffering from major water ingress. Moisture was entering living areas and bedrooms, with some units becoming uninhabitable due to mould and damp. CPR conducted a full façade audit, identified failed sealing and extensive concrete spalling, and delivered a complete remedial waterproofing program.

Key Components of an Effective Waterproofing System

All damaged joints removed and replaced.

Brick mortar repointing and Helifix bar installation

Render and concrete spalling repairs

Sealant renewal and waterproofing

Repainting of all previously painted external substrates

Metal surface painting and protection

Despite a 15-person crew on-site over a 25-week period, noise and disruption were kept to a minimum. The project benefited from seamless collaboration between the project consultant, engineering team, building manager, and owners committee—delivering a high-quality result with efficiency and care.

FAQs

What’s the difference between repointing and brick stitching?

Repointing restores the mortar between bricks or stones, while brick stitching is a structural repair technique used to stabilise cracked walls. Stitching involves embedding steel bars across cracks to prevent further movement.

Can you repair masonry on high-rise or difficult-access buildings?

Absolutely. All masonry repairs (e.g., repointing, crack stitching, or joint replacement) can be completed Scaffold-Free using CPR’s rope access and patented systems like PEARS® and SkyPod® BRMW, ensuring minimal disruption.

What effect does wet and damp weather have on bricks?

Prolonged exposure to moisture can lead to several issues. Water seeps into cracks or porous brick and mortar, leading to efflorescence, mould growth, and over time, spalling where the surface of the brick begins to flake or crumble. Repeated wetting and drying cycles can also weaken mortar joints and allow structural movement.

What mortar colours are available for repointing my property?

Mortar is available in a wide range of colours, and at CPR we match the existing mortar as closely as possible to maintain the building’s original look. For heritage or decorative projects, we can customise colour blends to suit both modern and traditional finishes.
