Renovating your home is one of the most exciting and rewarding projects you can take on. Whether you’re modernising an outdated kitchen or adding a sleepout, the promise of a better space keeps many Kiwis motivated. But without proper planning, renovations can quickly turn into costly and stressful nightmares. At Complete Home Renovations, we’ve seen firsthand what works and what doesn’t. Here are ten common renovation mistakes New Zealanders often regret, and how to avoid them.
1. Underestimating the Budget
This is the most common regret. Many homeowners set a budget based on ideal costs without allowing for real-world surprises. For example, a kitchen reno may start at $30,000 but blow out to $45,000 when asbestos is discovered behind the old cabinetry or the subfloor needs replacing.
How to avoid it: Always add a 10-20% buffer to your renovation budget. Consult a professional builder early to get realistic quotes based on current market rates, and don’t rely on TV shows for pricing expectations.
2. Not Getting the Proper Consents
Some homeowners assume council consent is only needed for major additions, but even a new deck or moving plumbing can require approval. We’ve seen projects stalled for months, or even partially demolished, due to unauthorised work.
How to avoid it: Check with your local council or engage a renovation company (like us!) that handles all permitting and compliance requirements for you. It’s not worth the risk to skip this step.
3. Poor Planning and Design
A common issue is designing as you go, which leads to disjointed rooms and inefficient layouts. For instance, adding a new bathroom without considering plumbing proximity can add thousands in pipework and water pressure issues.
How to avoid it: Work with a designer or architect to map out how the space will be used. Good design considers the flow of people, light, and utilities, not just looks.
4. Ignoring the Home’s Original Structure
Modernising a villa or bungalow without respecting its structure often results in mismatched styles or costly fixes. Removing a wall without checking if it’s load-bearing, for example, can compromise the home’s integrity.
How to avoid it: Renovate in harmony with your home’s original features. Use similar materials or styles where possible to blend old and new. Always consult a builder before making structural changes.
5. Choosing the Cheapest Quote
Low quotes may hide shortcuts. We’ve been called in to fix work where cheap contractors used incorrect insulation, unsafe wiring, or bathroom tiles that lifted within months.
How to avoid it: Look beyond the price tag. Check references, view previous work, and ensure your builder is licensed and insured. Quality workmanship saves money long-term.
6. Over-Customising
Installing a home gym in the lounge or a brightly coloured kitchen may be your dream, but it could deter future buyers. Unique choices like purple tiles or curved walls are hard to reverse.
How to avoid it: Personalise with decor, not permanent fixtures. Choose neutral, timeless finishes for big-ticket items like cabinetry and flooring. Add character through art, paint, and soft furnishings.
7. DIY-ing Beyond Your Skill Level
Tiling your own splashback or painting a feature wall? Go for it. But we’ve seen DIY waterproofing lead to major leaks and insurance issues. A poorly installed bathroom can cause $10,000+ in water damage.
How to avoid it: Stick to simple tasks (painting, landscaping), and leave plumbing, electrical, and structural work to the pros. It’s not just about looks, bad DIY can be dangerous.
8. Not Thinking About the Future
We often see couples renovate without thinking about kids, or retirees forget about accessibility. A second-storey extension might look great now, but may be impractical in later years.
How to avoid it: Plan ahead. Think about how your needs may change. Consider wide hallways, ground-floor bathrooms, or multi-use rooms that adapt over time.
9. Rushing the Timeline
Pushing trades to finish early often backfires. Paint doesn’t cure properly, floors get scratched because they weren’t protected, or critical inspections are skipped. The end result? You redo work within a year.
How to avoid it: Allow for delays. Weather, shipping issues, or unforeseen discoveries can all push out a timeline. Factor this in from the start and prioritise quality over speed.
10. Neglecting Lighting and Power Points
We’ve had clients call back after finishing a reno because they forgot to install enough outlets in the kitchen or proper task lighting in the bathroom. Retrofitting electrical work is messy and expensive.
How to avoid it: Plan your lighting and electrical layout during the design stage. Walk through your day-to-day routines and make sure every space is lit and powered for its purpose, especially high-use zones like kitchens, home offices, and bathrooms.
