Brick Repointing
Protecting the Structure of Your Home

The mortar joints between your bricks do far more than just hold them apart—they act as your home's primary defence against the elements. Over time, wind, rain, and frost naturally degrade this mortar. When it begins to crack, crumble, or recede, your walls become vulnerable to water ingress, damp, and structural issues.

Repointing is the process of carefully raking out this damaged mortar and replacing it with fresh, high-quality material, restoring both the strength and the weatherproofing of your property.

Does Your Property Need Repointing?

Mortar failure isn't always obvious at a casual glance, but there are several clear warning signs that indicate it's time to take action.

Visible Gaps and Crumbles

The most obvious sign. If you can see missing chunks of mortar, or if it crumbles to dust when you touch it, the joint has failed.

Receding Mortar Joints

If the mortar has worn back by more than 5mm to 10mm from the front face of the brick, water can begin to pool on the exposed brick edges, leading to rapid deterioration.

Damp Patches on Internal Walls

When external mortar fails, rainwater penetrates the brickwork. If you notice localised damp spots, peeling wallpaper, or blistering paint inside your home, failed pointing is a common culprit.

Frost Spalling (Flaking Bricks)

When water gets trapped behind compromised mortar and freezes, it expands. This pressure can cause the faces of the bricks themselves to crack, flake, or pop off entirely.

White Powdery Stains (Efflorescence)

A white, salty residue on your external walls indicates that water is moving freely through the brickwork and drawing out natural salts.

Our Process

A proper repointing job is all about preparation. Rushing the job or simply "smearing" new mortar over old, loose material will fail within a few seasons. We follow a strict, professional process to ensure a clean finish that lasts for decades.

Step 1
Assessment & Preparation

We inspect the brickwork to determine the original mortar type (such as traditional lime or modern cement) to ensure the new mix matches perfectly in strength, flexibility, and colour. Areas are safely zoned off, and windows/doors are protected.

Step 2
Raking Out the Old Mortar

Using specialised dust-extracted routing tools, we carefully remove the damaged mortar to a uniform depth (usually around 15mm–20mm). We cut back to a clean, sound surface without damaging the edges of your original bricks.

Step 3
Cleaning & Dust Removal

All loose debris and dust are thoroughly brushed or washed out of the open joints. Wetting the joints just before pointing ensures the bricks don't suck the moisture out of the fresh mortar too quickly, which would cause it to crack.

Step 4
Applying the New Mortar

The new mortar is firmly packed into the joints in layers. We use traditional hand-pointing techniques to ensure there are no air pockets and that the bond between the mortar and brick is completely watertight.

Step 5
Finishing & Striking

Once the mortar has began to set slightly, we "strike" or profile the joint (such as a weather-struck or flush finish) to match the style of your property and ensure rainwater sheds away from the joint cleanly.

Step 6
Final Clean Down

We brush down the entire wall face to remove any stray mortar tags, leaving a neat, professional, and visually striking finish that completely refreshes the look of your property.

  Why Professional Depth Matters

Simply slapping a thin layer of new mortar over old, crumbling joints (known as "face pointing") is a short-term fix. Without raking out to a proper depth of at least 15mm, the new mortar cannot form a mechanical bond and will quickly flake off during winter frosts.
