Getting three quotes for a welding job is good practice. But comparing them is harder than it looks. A quote for $380 and a quote for $620 for the same gate repair might represent exactly the same quality of work — or a $240 difference in hidden costs on the invoice. You need to know what you're comparing before you decide.
The 5 Things a Good Mobile Welding Quote Should Include
Before you get to price, check whether the quote actually contains these five things:
- A clear scope of work. "Weld the gate" is not a scope. A proper scope says: "Re-weld two separated hinge plates on existing tubular steel driveway gate, grind flush, cold galv finish." If the scope is vague, the job can expand without warning — and so can the invoice.
- Material specification. The quote should state what grade of steel, stainless, or aluminium is being used. Grade 304 stainless and grade 316 are priced differently. Mild steel and galvanised steel have different costs and finishes. If material isn't specified, it might not be included at all.
- Labour breakdown. You should see the call-out fee and hourly rate listed separately, not bundled into one number. This lets you verify the estimate is realistic for the scope.
- Inclusions and exclusions. Does the quote include consumables (gas, wire, grinding discs)? Does it include travel within a certain radius? Is GST included or not? These are common hidden-cost sources.
- An estimated timeline. Not legally binding, but a welder who's thought through the job should be able to tell you whether it's a 1-hour or a 4-hour job.
Red Flags in Mobile Welding Quotes
These are the signals that a quote will cause problems later:
- Vague scope. Any quote that describes the job in fewer words than you described it to them over the phone is incomplete.
- No mention of insurance. Public liability insurance is non-negotiable for work on private or commercial property. If it's not mentioned, ask directly. If they can't produce a certificate of currency, walk away.
- A firm price before seeing the job. A ballpark range over the phone is fine — that's useful. A firm fixed price given without a site visit or photos is a red flag. They're either guessing or planning to vary it once on-site.
- Unusually low price. A quote 40–50% below market rate usually means no insurance, unqualified work, or substandard consumables. The welding might look fine until load is applied.
- No call-out fee shown separately. Some operators bundle the call-out into the total and show you one number. That's fine for simple jobs, but it makes comparing across quotes impossible. Ask them to break it down.
Questions to Ask Before Accepting
A reputable operator won't be bothered by these questions — they should have quick, clear answers:
- "Is this price inclusive of GST?"
- "What happens if the job runs over the estimated hours?"
- "Are materials included, or quoted separately?"
- "What's your public liability cover?"
- "Do you carry a White Card for site access if needed?"
- "Can I see photos of recent similar work?"
If any of these questions creates hesitation, that's your signal.
Why Cheapest Is Often a False Economy
A weld that looks fine on day one can fail under load six months later — especially on gates, structural connections, and load-bearing handrails. The rework cost is almost always higher than the saving on the original job: you're paying for a second call-out fee, additional labour, and sometimes materials to cut out and redo the failed work.
Uninsured work is a bigger risk. If a substandard weld on a gate causes injury or property damage, and the operator isn't insured, you're the one with exposure. This isn't theoretical — it's the reason public liability is a baseline requirement for any legitimate mobile welder.

How to Get Comparable Quotes
The cleanest approach is to give every operator the same written brief — a few sentences describing the job, the metal type if known, the location, and the access conditions. If you send photos, send the same photos to everyone.
When quotes come back, compare them on this basis:
- Call-out fee (separate)
- Hourly rate (separate)
- Estimated hours
- Materials included? (yes/no, and at what cost)
- Total ex-GST
- Insurance confirmed (yes/no)
- Certifications relevant to the job
A table makes this easy. The quote with the best combination of clear scope, verified insurance, and realistic labour estimate is the one worth choosing — price is one input, not the deciding factor.
