Why this matters: brickwork is more than just laying bricks
Brickwork looks straightforward until you factor in structural stability, moisture control, footing depth, council rules and the quality of the finished appearance. In New Zealand, some small non-structural jobs are suitable for capable DIYers, but many bricklaying tasks need professional skill, and some may require a building consent or another specialist trade.
The biggest mistake homeowners make is assuming that because a wall is small, it’s automatically simple. A poorly built brick feature can crack, leak, fail under wind or earthquake movement, or create a safety hazard. If the work is connected to a home’s structure, boundary, drainage, retaining function or fire safety, it is worth pausing before you pick up the trowel.
What a homeowner can usually DIY
A competent DIYer can often take on small, low-risk brickwork projects if they are not structural and do not affect weather-tightness, drainage or compliance. Examples include:
- repairing a few loose or cracked bricks in a garden wall that is clearly non-loadbearing
- repointing small areas of mortar on a decorative feature, provided the wall is sound
- replacing damaged pavers or bricks in a barbecue surround or garden edging
- building very small garden features, such as low edging or planters, if they are not retaining soil and are well below any height that could make them unstable
- cosmetic cleaning of brickwork using appropriate methods and products
If you’re doing any of the above, keep the work simple and reversible. Use the right mortar type, match existing brick sizes and finishes, and avoid making the repair look better while secretly weakening the wall.
DIY jobs that still need care
Even “small” jobs can go wrong if you skip prep. For example:
- Repointing: raking out joints too aggressively can damage brick edges. Use hand tools where possible and avoid power tools unless you know what you’re doing.
- Cleaning: harsh acids can stain or etch brick and mortar. Always test a small area first.
- Minor patch repairs: new mortar should be compatible with the old. Very hard modern mortar on older brickwork can cause future cracking.
For DIY work, it’s sensible to budget for proper tools and materials rather than trying to save money with shortcuts. A small repair might cost only tens or a few hundred dollars in materials, but a poor repair can make a later professional fix more expensive.
Bricklaying jobs that should be left to a professional
Many bricklaying tasks in a New Zealand home are not suitable for DIY, even if they look manageable. These should generally be handled by an experienced bricklayer, and in some cases other licensed or regulated trades may also be involved.
| Job | DIY? | Why |
|---|---|---|
| Decorative low garden edging | Sometimes | Low risk if not retaining soil or supporting loads |
| Small non-structural repointing | Sometimes | Possible for minor cosmetic repairs if the wall is sound |
| Brick veneer on a house wall | No | Affects building envelope, fixing systems and weather-tightness |
| Retaining wall | No | Structural and drainage-critical; failure can be dangerous |
| Chimney repair or rebuild | No | Structural, weatherproofing and fire safety issues |
| New brick pier or column | Usually no | May carry loads or need foundations and consent |
| Brick barbecue connected to flues/services | No | May involve fire safety, gas, ventilation or other regulated work |
| Repairs near foundations or slabs | No | Can affect structure and moisture management |
Why these jobs need a pro
A qualified bricklayer understands:
- correct footing and base preparation
- movement joints and crack control
- wall tie requirements for veneer work
- moisture management and flashing details
- load paths, stability and support
- how local conditions affect performance, including wind, coastal exposure and seismic movement
New Zealand’s climate can be hard on masonry. Coastal salt air, heavy rain, and the country’s seismic environment make proper detailing important. A wall that is fine for a few months can fail after the first wet winter or a minor ground movement if it was built badly.
Where consent and compliance come into play
Not every brick job needs a building consent, but many do. If the work is part of building, extending or altering a structure, check with your local council before you start. Building consent requirements depend on the size and purpose of the work, whether it is structural, and how it affects the building envelope or safety.
Common situations where you should assume extra checks are needed:
- Retaining walls: especially where the wall is supporting ground, carrying surcharge loads, or is near boundaries or driveways
- Changes to a house exterior: including brick veneer additions, new openings, or major repairs that affect the weathertight envelope
- Chimneys and fireplaces: may involve structural and fire safety considerations, and sometimes other specialist work
- Work near services: if excavation could affect plumbing, gas, drainage or cables
- Anything close to a boundary: height and setback rules may apply under local district plans
If the project also involves plumbing, gasfitting, drainlaying or electrical work, those parts must be carried out by appropriately authorised people. In New Zealand, those trades are regulated separately. Don’t assume a bricklayer can just “sort it out” if a pipe, gas line or wiring is in the way.
For bigger or more complex projects, ask your bricklayer whether they have experience working with a building consent process. A good tradie will know when documentation, engineering or inspections are likely to be needed.
Safety risks homeowners often underestimate
Bricklaying is physically demanding and can be hazardous, especially on ladders, scaffolding or uneven ground. Common risks include:
- back, shoulder and wrist strain from lifting bricks and blocks
- dust exposure from cutting bricks and mixing mortar
- eye injury from chips and flying debris
- falls from ladders, roofs or unprotected edges
- collapses if a wall is built without proper support or bracing
- cuts from tools and sharp masonry edges
If you’re DIYing a tiny repair, basic PPE matters: gloves, eye protection, sturdy boots and a dust mask when cutting or mixing dry materials. Use stable access equipment and never work on an unstable wall or stack of bricks.
For larger work, the safety picture changes quickly. Once you need scaffolding, high cutting volumes or repeated lifting, the value of hiring a professional increases. You are not just paying for speed; you are paying for safer methods, the right equipment and experience with unstable masonry.
What a professional bricklayer gives you that DIY usually doesn’t
A good bricklayer brings more than neat lines. They bring judgement.
Professionals can:
- assess whether the existing structure is sound enough to repair
- match mortar colour, joint profile and brick size more accurately
- spot hidden issues such as failing foundations, water ingress or poor flashing
- complete work to a standard that suits both appearance and durability
- coordinate with other trades and council requirements when needed
- reduce the risk of a repair failing and having to be redone
If you are planning to sell your home, professionally completed brickwork can also help avoid questions from buyers or building inspectors later. Visible patch jobs, uneven lines or repairs that don’t match the original finish can be easy to spot.
How to decide: DIY or call a bricklayer?
A useful rule is this: if the work is decorative, low-level, non-structural and easy to reverse, DIY may be reasonable. If it supports anything, holds back soil, affects moisture, sits near services, or forms part of the home’s external envelope, get a professional involved.
Ask yourself:
- Is this wall carrying weight or holding back soil?
- Could a failure injure someone or damage the house?
- Will the work change the weather-tightness of the home?
- Could it affect plumbing, gas, drainage or wiring?
- Might the council require consent or inspection?
- Would I trust my own work here in a storm or after a small quake?
If the answer to any of those is “maybe”, it is probably not a DIY job.
How to hire the right bricklayer in New Zealand
When you do need a professional, don’t just hire the first person who says they can start next week. Get at least two or three written quotes and compare scope, materials, exclusions and timing. In the current market, availability can vary by region and season, with spring and summer often busier for exterior work.
Check:
- references or recent similar projects
- photos of completed work, especially if you need matching brickwork
- whether they are experienced with the type of job you need
- whether they will arrange or work with any required consent/engineering
- whether the quote includes materials, scaffolding, waste removal and site clean-up
- insurance cover, especially public liability and contract works where relevant
Ask clear questions before you accept a quote:
- Have you built or repaired this type of brickwork before?
- Will this job need council consent or an engineer’s input?
- How will you match existing bricks and mortar?
- What happens if hidden damage is found after work starts?
- What warranty or workmanship guarantee do you provide?
A professional bricklayer should be happy to explain the process in plain English and flag any compliance issues early.
The practical bottom line
DIY can be fine for small cosmetic brick repairs, minor repointing and simple garden features, provided they are non-structural and don’t affect drainage, services or weather-tightness. But once brickwork becomes structural, retains soil, sits on or near the house envelope, or involves consent or other regulated trades, it is time to bring in a professional.
The safest and most cost-effective approach is often to do the simple prep you’re confident with, then leave the technical bricklaying to someone who does it every day. That way you protect your home, stay on the right side of NZ building requirements, and avoid paying twice to fix a DIY mistake.
