Choosing the right concrete resurfacing contractor is the most important decision in your project. The difference between a driveway that looks great for 20 years and one that’s peeling by year 3 almost always comes back to the contractor, their preparation standards, product choices, and workmanship. This guide gives you the practical framework to evaluate any concrete contractor on the Central Coast and make a confident choice.
Why Contractor Selection Matters More Than Product Selection
It’s tempting to focus on the product, “should I get spray-on or stencil?”, but the most technically advanced product applied poorly will fail faster than a standard product applied correctly.
The key variables in a resurfacing outcome are:
- Surface preparation (grinding, crack filling, priming), 60% of the outcome
- Product quality and appropriateness for the application, 25% of the outcome
- Application technique, 15% of the outcome
All three are contractor-controlled. Choosing a skilled, experienced contractor who uses appropriate products and prepares correctly is the single most important decision.
Step 1: Verify Licensing and Insurance
Contractor Licence (NSW)
In NSW, concrete work may be subject to the contractor licensing requirements under the Home Building Act 1989. While pure concrete resurfacing (applying overlays and coatings) may not always require a building licence depending on the scope, any contractor working on residential premises should be able to provide evidence of appropriate licensing.
Check the NSW Fair Trading licence register at fairtrading.nsw.gov.au, you can search by contractor name or licence number.
Public Liability Insurance
Any contractor entering your property to perform work should carry public liability insurance of at least $5 million, $10 million is preferred for residential work. Ask for a current certificate of currency from the insurer.
If a contractor without adequate insurance damages your property or causes injury to a third party while working on your site, you as the property owner may be partially liable for the resulting claims.
Workers Compensation Insurance
If the contractor employs workers (anyone other than a sole trader working alone), they must hold workers compensation insurance in NSW. Ask for confirmation. Unlicensed contractors who employ workers without workers compensation are operating illegally and expose you to liability if a worker is injured on your property.
Step 2: Assess Experience and Specialisation
Years in Business
Look for contractors who have been operating on the Central Coast for at least 3-5 years. Concrete resurfacing quality issues often don’t appear immediately, a product failure might take 12-24 months to manifest. A contractor who has been in business long enough to have customers from 5+ years ago and can provide references from that period has demonstrated that their work holds up over time.
Relevant Project Experience
Ask specifically about experience with:
- The type of surface you need done (driveway, pool surround, garage floor, commercial)
- Surfaces similar in condition to yours (if your concrete is heavily damaged or unusual)
- Projects in coastal conditions (if your property is near the beach at Terrigal, Umina, or similar)
Portfolio and References
Request before-and-after photos of recent similar projects in your area. Request at least two references from customers with completed projects you can contact directly. A contractor who can’t provide references from recent satisfied customers is a concern.
Step 3: Evaluate the Quote
A professional concrete resurfacing quote should be in writing and should specify:
The scope of work:
- Exactly what areas are being treated (with measured areas in m²)
- What surface preparation will be done (grinding depth, crack filling, stain treatment)
- What products will be used (brand name and product type, not just “epoxy primer” or “overlay”)
- Number of coats for each product
- Specified finish type and colour
- Non-slip rating if applicable
What’s included:
- All labour and materials
- Surface protection of adjacent areas
- Clean-up on completion
What’s excluded: A good quote notes what is not included, common exclusions include structural crack repair, slab lifting, lead paint testing.
Price and payment terms:
- Fixed price or schedule of rates (fixed price is preferable for homeowners)
- Deposit amount (10-20% is standard; anything over 30% upfront is unusual)
- Milestone payments if applicable
- Warranty period and terms
Quote comparison tip: If one quote is significantly cheaper than others, find out why. A $4,000 quote vs $7,000 quotes for the same job usually means either fewer coats, inferior products, less preparation, or the cheaper contractor is proposing something different. Ask each contractor to explain their preparation and product specification in detail.
Step 4: Ask the Right Questions
Use these questions to evaluate any contractor:
On preparation:
- What preparation will you do before applying any product?
- Do you use diamond grinding equipment or pressure washing only?
- How do you handle cracks before overlaying?
- What primer system do you use, and why?
On products:
- What specific product will you use for the overlay?
- What is the topcoat product and how many coats?
- Can you provide the product data sheet (PDS) for the products you’re using?
- Is the product rated for outdoor use in coastal conditions?
On the process:
- How long will the job take?
- What access do I need to provide?
- How long before I can use the surface?
- What temperature and humidity conditions do you require?
- What happens if it rains?
On their business:
- How long have you been doing concrete resurfacing on the Central Coast?
- Can you provide two or three references I can contact?
- Do you carry public liability insurance? Can I see a current certificate?
- What warranty do you offer on the workmanship?
Step 5: Recognise Red Flags
These are warning signs that should make you cautious or prompt further investigation:
Red Flag 1: No physical sample or portfolio A contractor who can’t show you physical finish samples or photos of recent completed work cannot confirm that their outcome will match your expectation. Always view samples before committing.
Red Flag 2: Quote delivered on the spot without measurement An accurate quote requires measuring the area, assessing the existing condition, and allowing time to calculate material quantities. A quote delivered in the car on a 10-minute site visit (or over the phone without a site visit) is an estimate, not a fixed price, it will change.
Red Flag 3: Cash-only or significantly lower than all other quotes A price substantially below other quotes (more than 20% lower for comparable scope) usually indicates skipped preparation steps, inferior products, or no insurance, which passes risk to you.
Red Flag 4: Cannot specify the products being used A contractor who says “we use a quality overlay” but can’t name the brand or provide a data sheet is either not confident in their product knowledge or is using unspecified products they can’t stand behind.
Red Flag 5: Requests a large deposit A deposit of 10-20% is standard. Requesting 50%+ upfront, or asking for cash payment in full before completion, is unusual and creates risk.
Red Flag 6: No warranty offered A professional concrete resurfacing contractor should offer a workmanship warranty of at least 2-3 years (longer for professional-grade products and applications). If no warranty is offered, ask why.
Red Flag 7: Unwilling to provide references Any established, confident contractor can provide references. Reluctance or inability to do so is a significant concern.
Red Flag 8: Pressure tactics “This price is only good today” or “I’ve got a job nearby so I can do it cheaper if you sign now” are sales tactics that discourage the due diligence you need to do. A quality contractor’s pricing doesn’t change with time pressure.
Getting Multiple Quotes, How Many and How to Compare
How many: For jobs up to $5,000, two quotes is adequate. For jobs $5,000 to $20,000, three quotes. For jobs above $20,000 (commercial, large strata projects), three or more formal written quotes.
How to compare:
- Ensure quotes cover the same scope (same m² area, same preparation, same finish type)
- Check product specifications, are the same categories of product specified?
- Check warranty terms
- Check payment terms and deposit
- Check timeline and scheduling
Do not compare only the total price. Compare value, what do you get per dollar, and who are you trusting to deliver it?
Questions to Ask References
When you call a contractor’s references, ask:
- Did the contractor arrive on time and complete the job on the agreed schedule?
- Were there any issues with the finished product? If so, how did the contractor respond?
- How does the surface look after [X months/years]?
- Did the finished result match what you were shown or quoted?
- Would you use this contractor again or recommend them?
Central Coast Market Context
The Central Coast concrete resurfacing market has a mix of:
- Established local contractors who have been operating 10+ years
- Tradies who do concreting broadly and offer resurfacing as a secondary service
- Sub-contractors who work under larger contractors and occasionally take direct jobs
- Interstate or outer-regional operators who come to the Central Coast for work
The established local contractors typically offer the best combination of experience, accountability, and ongoing relationship if you need maintenance or warranty work. A contractor who doesn’t operate locally as their primary market may be harder to reach if issues arise post-installation.
Frequently Asked Questions
Do I need a licensed builder for concrete resurfacing? For residential concrete overlays and coatings (surface treatments), a specific builder’s licence is not universally required if the work is maintenance in nature. However, any contractor claiming to be a builder should be licensed, and all contractors should be adequately insured. When in doubt, request their licence number and check it.
Can I check if a contractor has had complaints? Yes. NSW Fair Trading maintains a public register of licence holders and disciplinary actions. You can also check the ACCC’s Scam Watch for business name searches. For larger contractors, a Google search for the business name plus “reviews” or “complaints” will surface any publicly documented issues.
How much should I pay as a deposit? A deposit of 10-20% to secure scheduling is standard in the Central Coast market. Deposits of more than 30% before work commences are unusual. Never pay more than 10-20% for a job that hasn’t started.
What happens if the contractor’s work fails during the warranty period? Notify the contractor in writing (email creates a record) with photos of the issue and the date it was first observed. A reputable contractor will arrange to inspect and repair at no cost if the failure is within the warranty scope. If the contractor doesn’t respond, escalate to NSW Fair Trading’s home building complaint process.
Is the cheapest quote ever the best choice? Occasionally, if the cheapest quote genuinely represents the same scope, same products, and the contractor has excellent references. But “cheap” usually means something is different, and in concrete resurfacing, what’s usually different is the preparation, which is the most important step.
