Hiring a concrete resurfacer is a significant investment — particularly in Port Stephens, where the coastal environment means that product quality and preparation standards make the difference between a job that lasts 15 years and one that fails in three.
Most homeowners don’t know what to ask. They get a price, it sounds reasonable, and they book. Then they find out the hard way — when the overlay starts peeling two years later — that the contractor cut corners on preparation or used products not rated for coastal conditions.
This checklist covers what to ask any contractor before you commit.
1. Are You Licensed Through NSW Fair Trading?
Why it matters: In NSW, certain building work requires a contractor licence through NSW Fair Trading. Concrete coating and resurfacing work on residential properties can fall under these requirements depending on the scope and value.
What to ask:
- “What is your NSW Fair Trading contractor licence number?”
- “Is your licence current and valid for this type of work?”
How to verify: You can check any contractor’s licence at nsw.gov.au/licensing/check-a-licence. It takes 30 seconds and is always worth doing.
Red flag: A contractor who can’t or won’t give you a licence number. Unlicensed contractors have no accountability through the fair trading system.
2. Do You Carry Public Liability Insurance?
Why it matters: If a contractor causes property damage or someone is injured during the work, your home insurance may not cover it if the contractor is uninsured. You could be liable for the cost.
What to ask:
- “Can you provide your certificate of currency for public liability insurance?”
- “What is the coverage amount?” (Minimum $5 million is standard for residential trade work)
What to do: Ask for a copy of the certificate. A professional contractor will provide this without hesitation.
3. What Specific Products Are You Using?
Why this matters in Port Stephens: Coastal environments require specific products. A contractor who answers this vaguely — “we use good quality stuff” or “a professional concrete overlay” — hasn’t thought about coastal product specification. Specific products have specific performance ratings. Vague answers suggest commodity-grade products.
What to ask:
- “What overlay system are you using, and what’s the brand?”
- “What sealer goes on top, and what’s its UV rating?”
- “Are these products rated for coastal conditions?”
- For pool surrounds: “Is the overlay/sealer formulation chlorine-resistant?”
Good answers: Named products with specific coastal credentials — e.g., “Dulux Avista overlay system, with a Dulux UV-stable polyurethane topcoat.” The contractor can point you to the product datasheet.
Red flags: Vague product descriptions, can’t name the brand, dismisses the question as unimportant.
4. What Does Your Surface Preparation Include?
Why it matters: Preparation is the single most important determinant of how long a resurfacing job lasts. Contractors who cut corners on prep — minimal cleaning, skipping crack filling, inadequate priming — produce jobs that fail early.
What to ask:
- “Walk me through your preparation process for my surface specifically.”
- “How do you handle existing cracks?”
- “What do you do about the old sealer on my driveway?”
- “Do you use a bonding primer? What type?”
Good answers: A detailed description covering cleaning (including what cleaning products or methods), crack routing and filling, removal of old failed sealer, and primer application with a named product.
Red flags: “We just clean it and put the product on.” Any suggestion that preparation is quick or minimal. Not mentioning primer.
5. Can You Show Me Examples of Your Work in Port Stephens?
Why it matters: Concrete resurfacing in coastal environments is different from inland work. A contractor with extensive inland experience may not have adapted their methods for the coastal conditions in Port Stephens. Seeing completed local work gives you evidence of what they produce.
What to ask:
- “Do you have photos of completed jobs in Port Stephens or Port Stephens suburbs?”
- “Can you give me a reference from a recent local job?”
What to look for: Photos showing clean, uniform results without visible delamination, blistering or colour inconsistency. Recent jobs (within 1–2 years) in Port Stephens conditions are more relevant than photos of inland jobs from 5 years ago.
6. What Is Your Warranty?
Why it matters: A warranty tells you what the contractor stands behind. A contractor who won’t put a warranty in writing is a contractor who isn’t confident in their work.
What to ask:
- “What workmanship warranty do you provide?”
- “Is this warranty in writing?”
- “What does the warranty cover? What does it exclude?”
- “Does the manufacturer provide any product warranty?”
Good answers: A written workmanship warranty of at least 2 years, covering defects in materials and workmanship. Some contractors offer longer warranties — 5 or even 10 years — on premium jobs. Product manufacturers like Dulux provide their own product warranties.
Red flags: Verbal-only warranty, “we’ll fix it if anything goes wrong” without specifics, no written documentation.
7. Who Will Actually Do the Work?
Why it matters: Some contractors are primarily salespeople or project managers who subcontract the actual labour. This isn’t necessarily a problem, but you should know whether the person quoting is the person laying the overlay — quality control varies when work is subcontracted.
What to ask:
- “Will you or your own employees be doing the work?”
- “If you use subcontractors, are they covered under your licence and insurance?”
- “Will you be on-site during the job?“
8. What Is the Estimated Timeline?
What to ask:
- “How many days will the job take?”
- “What is the cure time before I can use the surface?”
- “How far out can you schedule the work?”
Understanding the answers: A simple single driveway reseal is typically 1 day. A spray-on overlay is 1–2 days. A full outdoor area (pool surround + patio + driveway) is 2–4 days. Anything significantly faster than this suggests shortcuts.
Cure times for vehicle traffic should be 72 hours for driveways. Pool surrounds need 48 hours before the pool is used.
9. Is the Quote Fixed Price or Estimate?
What to ask:
- “Is this a fixed-price quote or an estimate?”
- “Under what circumstances could the price change?”
- “Are there any potential additional costs you haven’t mentioned?”
What to expect: A professional contractor should be able to give you a fixed-price quote for a job they’ve properly assessed. An “estimate” that comes in significantly higher than quoted is a problem. Legitimate additional costs (discovering significant crack repair needs during preparation that weren’t visible in photos) should be communicated before work begins, not presented as a surprise on the invoice.
10. For Pool Surrounds: Will It Be Non-Slip Compliant?
What to ask:
- “Will the pool surround meet AS 4663:2013 slip resistance requirements after resurfacing?”
- “What aggregate size or texture do you use for the non-slip finish?”
- “How is the non-slip incorporated — in the overlay or in the sealer?”
Good answers: Confirmation of P4 or R11 compliance, specific description of how non-slip is achieved (aggregate in topcoat sealer, or incorporated in the overlay coat), and acknowledgement that non-slip on a pool surround is non-negotiable.

Red Flags Summary
If any of these come up during a contractor conversation, proceed with caution:
- Can’t provide a licence number or insurance certificate
- Won’t name the specific products being used
- Describes preparation as quick or minimal
- Only willing to do verbal warranty (no written)
- Significantly undercuts all other quotes (usually means corners will be cut)
- Dismisses your coastal concerns as not important
- Can’t show you local Port Stephens examples
- Pressures you to decide immediately or offers a “today only” price
Frequently Asked Questions
Is a quote in writing legally required? For work over a certain value in NSW (generally $1,000+), contractors are required to provide a written quote. A written quote also protects both parties by defining the agreed scope and price.
What should I do if a contractor starts work without full preparation? Speak up immediately. If you’re watching them skip crack filling or apply product without primer, raise it on the spot. Once an inadequately prepared overlay is applied and cured, the damage is done.
Is the cheapest quote usually the worst option? Not always, but significantly below-market quotes usually indicate corners cut somewhere — typically in preparation, product quality, or both. Get three quotes and be suspicious of any that are 30%+ below the other two without a clear explanation.
