Repointing Brickwork in Sydney: Do You Need It? Signs, Process & Cost

Mortar looking cracked, sandy, or falling out? You might not need to rebuild your wall—but you probably do need repointing. This simple but essential process restores the strength and appearance of your brickwork without replacing the bricks themselves.

In this post, we’ll cover:

What repointing is (and what it isn’t)
Signs you might need it
The step-by-step process
Costs involved
How it ties into building warranties and compliance

Whether you're a homeowner dealing with a new build defect or a builder responding to warranty claims, knowing when to repoint—and how to do it right—can save time, money, and disputes.

🔍 What Is Repointing?

Repointing is the process of removing deteriorated, damaged, or loose mortar from the joints between bricks, and replacing it with fresh, compliant mortar. It doesn’t involve removing or replacing the bricks—just the mortar joints.

Repointing is often used:

In older homes with wear over time
In new homes where the mortar has failed early
After damage from weather, cleaning, or poor workmanship

🧱 What Repointing Is Not

It’s not just patching cracks with filler or sealant
It’s not pressure-washing or painting over the joints
It’s not a fix-all—if the mortar failure is due to a poor mix, acid damage, or structural movement, it must be diagnosed first

That’s why we always recommend mortar testing before repointing when the cause of deterioration is unclear.

⚠️ Signs You May Need Repointing

If you notice any of the following signs in your brickwork, repointing may be necessary:

Mortar that crumbles easily under your finger
Gaps forming between bricks
Sandy, powdery, or loose mortar
Water leaks or rising damp
White staining (efflorescence) or orange acid streaks
Hairline cracking along joints

In new builds, these are often signs of incorrect mortar mix, over-acid cleaning, or poor bricklaying technique—issues we can confirm through testing.

🧪 Do You Need Testing Before Repointing?

In many cases—yes. Especially if:

Your build is under warranty
The builder disputes liability
The staining or mortar failure appeared soon after construction
You suspect chemical damage (acid cleaning, waterproofing agents, etc.)

We arrange chemical mortar testing through accredited labs and provide defect reports that can be used in warranty claims, dispute resolution, and insurance processes.

🛠 How Repointing Works

Here’s a simplified overview of the repointing process:

Inspection & Testing (if required)
Determine the extent of damage and cause of mortar failure.
Mortar Removal
Old or damaged mortar is raked out to the required depth—usually 10–20mm.
Cleaning the Joints
Dust and debris are removed to allow for strong adhesion.
Mixing New Mortar
A compliant mortar is prepared—matching strength, colour, and texture as needed.
Repointing the Joints
New mortar is packed into the joints and tooled to match the original style (flush, raked, etc.)
Curing & Cleanup
The mortar is left to cure naturally and then gently cleaned for a consistent finish.

We carry out licensed repointing work across Sydney, and can match almost any mortar style—including heritage joints and modern builds.

💰 How Much Does Repointing Cost in Sydney?

Costs vary depending on:

Access and scaffolding needs
The extent of the damage
Type of joint (flush, rolled, raked, etc.)
Whether bricks also need to be replaced

General guide:

Minor repointing (1–2 walls): $1,200–$2,500
Full home façade or wraparound: $4,000–$7,500+
Testing & reporting add-ons: $600–$1,200

We provide clear, obligation-free quotes before any work begins.

🏠 For Homeowners: What You Need to Know

If your new home is showing signs of mortar failure, repointing may be the fix—but only if the cause is confirmed. Don’t let your builder dismiss it as “cosmetic” or “normal drying.” If the mortar is weak, it can lead to serious issues like water ingress, brick shifting, and even structural damage.

We work with homeowners, warranty departments, and inspectors to get the facts straight—and repairs done right.
