Stop calling a tradie for things you can fix yourself.
The shift toward DIY is growing fast in Australia. With the right tools and a bit of know-how, most common home repairs are well within reach — and cost a fraction of the price.

Skill level
Australians are increasingly choosing DIY over subcontracting, driven by cost-of-living pressures and a growing desire for hands-on control over their homes. The good news: most common household problems are far easier to fix than you'd think — if you have the right tools and a clear guide.
⚠️ Important: This guide covers DIY-legal repairs. Electrical work beyond basic fixture changes and all gas work must always be performed by a licensed tradie in Australia. When in doubt, call a professional.
Inside the Home
01
Fix a Running or Leaking Toilet
Easy
A constantly running toilet wastes thousands of litres of water and adds significantly to your water bill. In 95% of cases, the fix is a worn toilet fill valve or flapper — both are cheap parts available at any hardware store.
1
Turn off the water supply valve behind the toilet2
Flush to empty the cistern, then remove the lid3
Identify whether the flapper or fill valve is faulty4
Replace the faulty part (push-fit, no tools needed)5
Turn water back on and test — done in under 30 min
No special toolsParts under $15Saves $$$ on water bills
02
Patch a Hole in Plasterboard (Gyprock)
Easy
Door handle holes, picture hook damage, or accidental impacts leave unsightly holes in walls. A plasterboard repair kit handles holes up to 15cm wide without needing to cut or replace panels.
1
Clean edges of the hole and remove loose plaster2
Apply self-adhesive mesh patch over the hole3
Apply joint compound in thin layers, feathering edges4
Sand smooth when fully dry (4–8 hours)5

03
Re-seal a Leaking Window or Door Frame
Easy
Gaps around window and door frames let in moisture, draughts, and insects. Re-sealing with fresh silicone or weatherstrip seal is a weekend afternoon job that can dramatically reduce heating and cooling costs.
1
Remove old caulk with a utility knife and scraper2
Clean the surface thoroughly and let dry3
Apply painter's tape either side for clean lines4
Apply silicone caulk in a continuous bead5
Smooth with a damp finger, remove tape, let cure 24hr

04
Fix Squeaky Floorboards
Easy
Squeaky floorboards are caused by boards rubbing against each other or against nails. The simplest fix: apply talcum powder or a specialist timber lubricant into the gaps between boards. For persistent squeaks, a few screws driven at a slight angle through the board into the joist eliminates movement permanently.
1
Identify the squeaking board by applying weight2
Try talcum powder in the gap first (often works)3
If persistent, locate the joist with a stud finder4
Drive a countersunk screw through the board into the joist5
Fill screw hole with matching wood filler

05
Unblock a Slow or Clogged Drain
Easy
Before reaching for harsh chemicals, try a drain snake (also called a drain auger). They reach blockages 3–10 metres deep, physically remove the clog, and work on hair, soap buildup, and debris. A manual drain snake costs under $20 and solves the problem in under 10 minutes in most cases.
1
Remove the drain cover and insert the snake2
Rotate and push until you feel resistance (the blockage)3
Hook and pull out the blockage material4
Flush with hot water to clear residue
Drain snake under $20No chemicals needed
💡 Snagg It Tip: A drain snake, plunger, and tube of silicone together cost under $50 and handle 80% of the most common home problems. Keep them in a dedicated home repair kit.

06
Fix a Sagging or Sticking Gate
Easy
A sagging gate is almost always caused by loose hinge screws or a hinge that needs replacing. Tighten screws first — if the holes are stripped, fill them with timber dowel and wood glue before re-screwing. For gates that still stick after hinge adjustment, a plane or belt sander removes just enough material from the edge to clear the frame.

07
Re-Secure Loose Fence Palings
Easy
Loose fence palings are a security and appearance issue. Remove old rusted nails with a pry bar, straighten the paling, and re-attach with galvanised decking screws (which won't rust or loosen). For rotted rails, replace the rail section — most timber fencing uses standard sizes available at hardware stores.

08
Patch and Seal Concrete Cracks (Driveway / Path)
Intermediate
Cracks in concrete driveways and paths let water in, expand with freeze-thaw cycles, and become trip hazards. A concrete crack filler or polyurethane sealant handles cracks up to 20mm wide. Clean the crack with a wire brush, apply the filler, smooth flush, and seal once cured.

09
Clean and Reseal Timber Decking
Intermediate
Grey, weathered timber decking can be completely restored with a deck cleaner and fresh sealant or oil. Use a pressure washer or stiff deck brush with timber cleaner, let dry fully, then apply two coats of outdoor timber oil or sealant with a roller. The difference is remarkable and protects the timber for years.

Install a Outdoor Security or Motion Sensor Light
Easy
Solar-powered outdoor security lights require zero wiring — mount them with screws and they charge during the day, switching on automatically at night via built-in motion sensor. A high-quality solar security light costs under $40, installs in 15 minutes, and adds genuine security and visibility to any Australian home.
