Taking on a home renovation project is an exciting but daunting prospect. Whether you’re upgrading your kitchen, adding an extra room, or giving your home a fresh coat of paint, one big question always comes up: Should you do it yourself or hire a professional? While DIY projects can be rewarding and cost-effective, there are situations where calling in an expert is not just advisable but necessary. Let’s break it down so you can make the best decision for your home.

The Kiwi DIY Spirit

We Kiwis are known for our strong DIY culture. Whether it’s a backyard deck, a sleepout, or a minor home renovation, we love to get our hands dirty. Hardware stores like Mitre 10 and Bunnings are full of weekend warriors looking to tackle their next project. However, not all renovations are created equal, and some come with risks that could end up costing more in the long run if they’re not done right.

When DIY is a Good Idea

There are plenty of renovation projects that are well within the capabilities of a keen DIYer. These projects often require minimal expertise, pose little safety risk, and can be done with easily accessible tools and materials:

1. Landscaping and Outdoor Projects

Building a garden bed, laying pavers, installing a fence, or putting together a small deck are all achievable DIY tasks. Many outdoor projects don’t require consent, making them ideal for homeowners looking to improve their property on a budget.

2. Basic Flooring Updates

Laying click-together laminate or vinyl plank flooring can be a manageable DIY job. These materials are designed for easy installation and don’t require specialised tools. However, more complex flooring options like solid timber or tiles are best left to professionals.

3. Installing Flat-Pack Kitchens and Shelving

Flat-pack kitchens from retailers like Bunnings or Kaboodle can be DIY-friendly if you’re confident in your measuring and assembly skills. Likewise, installing floating shelves or pre-made cabinetry can be a great DIY task as long as you locate the wall studs properly.

When You Should Call in the Professionals

While some renovation jobs are perfect for DIY, others are best left to the experts. Some projects require specific skills, trade qualifications, or council consents. Cutting corners on these jobs could lead to costly mistakes or even legal issues.

1. Painting and Decorating

While painting may seem like an easy DIY task, achieving a professional finish requires skill, experience, and the right equipment. A high-quality paint job enhances the look and longevity of your home, while a poorly done one can result in uneven finishes, drips, and the need for costly touch-ups. If you want a flawless finish that lasts, hiring professional Wellington painters like Orkney Group is the best choice. Our expert team uses top-quality materials and proven techniques to deliver stunning, long-lasting results.

2. Electrical Work

In New Zealand, electrical work must be carried out by a licensed electrician. This includes installing new power points, light fixtures, or wiring. Attempting DIY electrical work is not only illegal but also extremely dangerous. A poorly wired house can cause serious fire hazards or electrocution risks. Hiring a qualified professional ensures compliance with NZ safety regulations and gives you peace of mind.

3. Plumbing and Gas Fitting

Like electrical work, plumbing and gas fitting are strictly regulated in New Zealand. If you need to install or modify water pipes, hot water cylinders, or gas appliances, you must hire a registered plumber or gasfitter. Small jobs like replacing a tap washer or installing a new showerhead can usually be done yourself, but anything beyond that should be left to the pros.

4. Structural Changes and Major Alterations

If your renovation involves removing walls, adding an extension, or altering the structure of your home, you’ll likely need a building consent from your local council. Structural changes require careful planning and expertise to ensure the integrity of your home isn’t compromised. Wellington builders with experience in renovations, like Orkney Group, can handle these projects professionally, ensuring all work meets New Zealand’s strict building codes.

5. Waterproofing and Tiling Bathrooms

Bathrooms require specialised knowledge due to the risk of leaks and moisture damage. Poorly done waterproofing can lead to costly repairs down the track. Licensed professionals know how to properly seal wet areas, install drains, and lay tiles for a long-lasting, leak-proof finish.

6. Roofing Work

Whether it’s replacing your roof, fixing leaks, or installing skylights, roofing is a high-risk job that requires professional skills. Working at heights comes with serious safety concerns, and incorrect installation can lead to water damage, mould, and costly repairs. Orkney Roofers have the right equipment and experience to do the job safely and correctly.

The Cost Factor: DIY vs. Professional Renovation Costs

One of the biggest reasons homeowners choose DIY over hiring a professional is cost. However, DIY doesn’t always mean cheaper. If a project goes wrong, fixing mistakes can be expensive. 

While DIY can save money on labour, it’s important to weigh up the risks. If you don’t have the necessary skills, a botched job could end up costing more to fix than hiring a professional in the first place.

Understanding NZ Building Regulations

If you decide to go the DIY route, make sure to check if you need a building consent. In New Zealand, many structural, plumbing, and electrical works require approval from the local council. Failing to get consent can lead to fines or complications when selling your home.

Some DIY work may be covered under exempt building work, but it’s always best to consult with a professional or check with your local council before starting.

Finding the Right Professionals

If your project requires expert help, finding the right tradesperson is crucial. Here are a few tips:

Get multiple quotes: Don’t settle for the first price you receive—compare at least three quotes.

Check credentials: Ensure your builder, electrician, painter, plumber, or other tradie is licensed and registered.

Read reviews: Look at online reviews or ask for references from past clients.

Choosing the Best Approach for Your Renovation

Deciding whether to DIY or hire a professional comes down to safety, skill level, and budget. While landscaping, shelving, and minor home improvements can be fun and cost-effective DIY projects, painting, electrical, plumbing, structural, and roofing work should always be left to the experts.
