Yes, hiring an aluminium scaffold tower is one of the safest and most practical ways to paint second-storey windows yourself — far safer than leaning a ladder against the wall for extended work. That said, there are important NZ safety requirements, setup rules, and limitations you need to understand before you get started.
Why a Scaffold Tower Is Better Than a Ladder for This Job
For a task like painting multiple windows at height, a mobile aluminium scaffold tower gives you a stable, level platform to stand on, somewhere to rest your paint tray and tools, and the ability to work comfortably for longer periods. Ladders are fine for quick jobs, but for second-storey work — typically 4–6 metres above ground — fatigue and awkward reach angles make ladders a genuine fall risk.
WorkSafe NZ identifies falls from height as one of the leading causes of serious injury in New Zealand, and this applies to homeowners doing DIY just as much as it does to workers on a job site.
What to Look for When Hiring a Tower
When you hire an aluminium scaffold tower in NZ, check the following:
- Working height vs. platform height: For a typical NZ two-storey home, you'll likely need a platform height of around 3–4 metres. Hire companies will help you calculate the right size.
- Outriggers/stabilisers: These are essential for towers above a certain height (generally when the height-to-base ratio exceeds 3:1). Always fit them as directed.
- Guardrails and toe boards: A compliant tower should include guardrails on all open sides of the platform and toe boards to stop tools rolling off.
- Condition of equipment: Check all frames, braces, pins, and castors before use. Refuse any equipment that looks bent, cracked, or corroded.
- Hire company instructions: A reputable hire company will provide an assembly manual. Read it fully before you start.
You can find scaffold tower hire at major NZ hire and trade suppliers, including Mitre 10 and Bunnings, as well as specialist hire companies.
Setting Up Your Scaffold Tower Safely
Follow these key steps every time:
- Choose firm, level ground. Soft or sloping ground is dangerous. Use base plates and adjustable screw legs to level the tower.
- Lock the castors before climbing. Every castor should have a brake — engage them all.
- Fit outriggers as specified in the manual, especially for taller configurations.
- Climb using the internal ladder or built-in rungs — never climb up the outside of the frame.
- Keep the platform tidy. Don't overload it; keep paint tins, rollers, and drop cloths organised and within safe weight limits.
- Never move the tower while someone is on it. If you need to reposition, everyone comes down first.
- Check the weather. Don't work on a scaffold tower in strong winds — this is especially relevant in many parts of NZ where wind can pick up quickly.
Height and Consent Considerations
For a straightforward DIY painting job using a hired mobile tower, you won't need a building consent. However, if you were erecting a more permanent or complex scaffold structure, different rules could apply. When in doubt, check with your local council or refer to MBIE Building Performance for guidance on Schedule 1 exemptions.
Protecting Your Home and Garden
Before you start painting, take a few minutes to:
- Lay down drop sheets on decking, paths, and garden beds below the work area.
- Mask off window frames, glass, and any cladding you don't want painted.
- Check the paint system you're using is suitable for the substrate — whether it's timber weatherboards, James Hardie fibre cement, or another material. Paint brands like Resene and Dulux have technical data sheets and helplines to advise on the right primers and topcoats.
When to Call a Professional
While a competent homeowner can safely use a hired scaffold tower for second-storey painting, there are situations where you should bring in a qualified tradesperson:
- Heights above two storeys, or where the building has complex rooflines, steep sites, or restricted access — these require proper scaffolding erected by a trained scaffolder.
- Large-scale repaints covering the full exterior — a professional painter with their own scaffold setup will often be more cost-effective and deliver a better result.
- Any electrical lines nearby. If there are overhead power lines close to where you'd be working, stop and contact your lines company before proceeding. Working near live lines is extremely dangerous.
- Unstable or difficult ground that makes safe tower setup impossible.
