Sydney has dozens of mobile welders — from highly certified tradespeople to uninsured sole traders working out of a beaten-up ute. Picking the wrong one can cost you far more than the job itself. Here's a checklist that helps you make the right call.
1. Check They're Insured
This is non-negotiable. Any welder working on your property or for your business should carry public liability insurance. Ask for a certificate of currency before they start. At minimum it should cover $5M — $10M or $20M is standard for commercial work.
An uninsured welder working on your property puts you at risk if something goes wrong — structural failure, fire, or injury. Don't skip this step.
2. Ask About Certifications
In Australia, welding qualifications matter for structural and load-bearing work. Look for:
- AS/NZS 2980 — Quality of welding (processes)
- AS 1796 — Certificate of competency (boilermakers/welders)
- AS/NZS ISO 9606-1 — Welder qualification for fusion welding
- White Card — Required for any construction site work
For non-structural domestic work (gate repairs, handrails, etc.) formal certification is less critical — but experience and quality photos of past work should be your guide.
3. Get the Rate Before They Arrive
A reputable mobile welder should be able to tell you their hourly rate over the phone. If they refuse to give you a rate until they've "seen the job", that's a yellow flag — it often means they'll name a price on the day based on what they think you'll pay.
Published pricing on a website is the gold standard. It signals that the business stands behind its rates and doesn't engage in on-the-spot negotiation.
4. Understand What's Included
Before agreeing to a price, confirm:
- Is travel/call-out included or extra?
- Are consumables (wire, gas, rod) included?
- Are materials (steel, stainless, aluminium) quoted separately?
- What happens if the job takes longer than estimated?
5. Look at Reviews — But Read Them Critically
Google reviews are useful but easily gamed. Look for:
- Reviews that mention specific job types (gate repair, boat hull, etc.)
- Consistent patterns across multiple reviews (on time, clean finish, quoted correctly)
- How the business responds to negative reviews
A business with 6 reviews and 5 stars is less trustworthy than one with 40 reviews and 4.6 stars.
6. Red Flags to Watch For
- Refuses to give any rate until on-site
- Can't provide proof of insurance when asked
- No website, no reviews, no verifiable identity
- Asks for full payment upfront
- Significantly below-market quotes (usually means cutting corners)
- Vague scope — "I'll assess when I get there"
The Bottom Line
A good mobile welder is transparent, insured, communicates clearly, and gives you a price you can plan around. If any of those boxes aren't ticked, keep looking.
