DIY vs Hiring a Tradie: When to Call a Professional

In Australia, you can legally perform most cosmetic and non-structural work yourself, including painting (interior and exterior), garden maintenance, furniture assembly, minor plaster repairs, replacing tap washers in standard compression taps, unclogging drains with a plunger, installing shelving, replacing shower heads, cleaning gutters, and basic fence maintenance. You cannot legally perform any electrical work (except changing light globes and resetting breakers), plumbing work beyond basic tap washer replacement and plunging drains, gas fitting of any kind, or building work above the value threshold in your state without the appropriate licence.

Savings vary significantly by job type. For painting, DIY typically saves 60 to 70 per cent compared to hiring a professional (materials cost $50 to $100 per room versus $300 to $600 professionally). For ongoing garden maintenance, owning basic equipment saves $1,200 to $2,000 or more per year after the first year. However, when you factor in tool costs, your time at a realistic value, potential mistakes, and the quality difference, actual savings are often 30 to 50 per cent less than expected. For jobs requiring licensed professionals, there are no legal savings from DIY — the work cannot legally be done by unlicensed individuals.

Unlicensed work — particularly electrical and plumbing — can void your home insurance coverage for claims related to that work. If unlicensed electrical work causes a fire, or unlicensed plumbing causes water damage, your insurer may deny the claim entirely. Even for work that doesn't require a licence, poor-quality DIY that causes damage may result in reduced payouts. Always use licensed professionals for electrical, plumbing, gas fitting, and structural work, and keep compliance certificates as part of your property records.

Hire a handyman for general maintenance tasks that don't require a specialist licence — things like door repairs, furniture assembly, picture hanging, minor timber work, silicone sealing, pressure washing, and odd jobs around the house. Handymen charge $50 to $90 per hour, which is lower than specialist tradies. Hire a specialist (plumber, electrician, builder) when the job requires a licence, involves significant safety risks, or requires specialist tools and expertise. A good handyman will tell you when a job is outside their scope and recommend a specialist.

Yes, developing basic DIY skills is a worthwhile investment for any homeowner. The ability to handle simple repairs, maintenance, and cosmetic improvements can save thousands of dollars over the years. Start with low-risk, high-value skills like painting, basic garden maintenance, and simple plaster repairs. Take workshops at Bunnings or Mitre 10, watch reputable YouTube channels, and practise on non-critical areas before tackling visible parts of your home. However, always respect the boundary between DIY-appropriate and professional-only work — no amount of YouTube tutorials qualifies you to do electrical or plumbing work safely and legally.

The most dangerous DIY activities are working at heights (gutter cleaning, painting eaves, roof work), using power tools without experience (angle grinders, circular saws, nail guns), any electrical work (even seemingly simple tasks carry electrocution and fire risks), and disturbing asbestos-containing materials in pre-1990 homes. Falls from ladders and roofs account for a significant proportion of spinal cord injuries in Australia. If a job requires you to be more than two metres off the ground, involves power tools you're unfamiliar with, or could disturb asbestos, hire a professional.

Homes built before 1990 in Australia may contain asbestos-containing materials (ACMs) in fibro sheeting, insulation, vinyl floor tiles, textured coatings, and even some cement products. You cannot identify asbestos by sight — it must be tested by an accredited laboratory. Before any renovation or repair work that involves cutting, drilling, or removing wall, ceiling, or floor materials in a pre-1990 home, have the materials tested. Many licensed asbestos assessors offer testing services for $150 to $400. If asbestos is found, removal must be performed by a licensed asbestos removalist — this is never a DIY job.
