Questions to Ask Before Hiring a Concrete Resurfacing Contractor

Central Coast Concrete Revival recommends asking every resurfacing contractor about their licence, their prep process, their sealer system and exactly what’s written into the quote before anyone signs anything, because on a Coast driveway the gap between a finish that lasts and one that peels within a year usually comes down to those answers, not the number on the page. This guide sets out what to ask and what a confident answer sounds like.

Why questions matter more than the price on the page

Two contractors can walk the same driveway and come back with quotes thousands of dollars apart, and it isn’t because one of them is ripping you off. It’s usually because they’re pricing different jobs. One has allowed for diamond grinding, crack repair and a coastal-grade sealer; the other has allowed for a pressure clean and a coat of paint over the top. Both numbers are real. Only one of them buys you a finish that’s still doing its job in five years.

That’s the entire logic behind this checklist: the questions below are designed to get prep, product and paperwork onto the table before price, so that when quotes do land side by side, you’re comparing like with like instead of guessing. Our concrete resurfacing cost guide covers what things should roughly cost; this page covers how to find out whether a quote reflects that cost honestly.

What licence and insurance should a concrete resurfacing contractor have?

In New South Wales, residential building work above certain contract values must be carried out by an appropriately licensed contractor. The dollar thresholds and licence categories are set and updated by NSW Fair Trading, and because they do change, the only reliable way to confirm a contractor’s current position is to check directly with NSW Fair Trading rather than take a business card at face value.

Before any work starts, it’s reasonable to ask:

• “What’s your licence number, and what class of work does it cover?” A legitimate operator will give you this without hesitation.
• “Can I see your certificate of currency for public liability insurance?” This protects you if something goes wrong on your property during the job.
• “Are you the person doing the work, or subcontracting it out?” Not a disqualifier either way, but worth knowing so you understand who’s actually accountable.

Every job arranged through Central Coast Concrete Revival is quoted and completed by appropriately licensed local contracting partners, and partner licence details are published here once confirmed. Our about page explains how that arrangement works and why we describe it plainly rather than dress it up.

What should you ask about preparation before any coating goes down?

Prep is where resurfacing jobs are actually won or lost, and it’s the single easiest thing for a lower quote to have quietly skipped. Worth asking directly:

• “What does your prep involve for a slab like mine?” Listen for specifics: pressure cleaning, diamond grinding, crack cutting and filling, oil-spot treatment. Vague answers (“we’ll clean it up and coat it”) are a signal to ask again.
• “Are you grinding back any old failing coating, or coating over it?” Coating over a peeling old finish is one of the fastest routes to an early failure.
• “How will you handle the cracks specifically?” Stable, narrow cracks are typically ground out and bridged as part of proper prep; ask what “typically” means for your slab.
• “What happens if you find hidden damage once cleaning starts?” A straight answer here (a process for photographing it, quoting the extra, and getting your sign-off before proceeding) is a good sign. No answer at all is not.

What should you ask about the sealer system?

On the Central Coast specifically, the sealer matters more than almost anywhere inland. Salt air and humidity are hard on standard sealers, and slabs within a few streets of the beach genuinely need a higher-grade UV-stable system to hold up. A contractor who raises this unprompted, rather than waiting to be asked, is usually one who’s thought about your job rather than quoting a generic template. Fair questions:

• “Is this sealer rated for coastal exposure?”
• “How often would you expect to need a re-seal, roughly?”
• “Does the quoted price include the coastal-grade option, or is that an upgrade?”

How do Coast quotes compare against realistic price ranges?

Before you can judge whether a quote is fair, it helps to know what “normal” looks like. These are the indicative guide ranges published in our cost guide, not a quote for your job specifically:

All figures are indicative Australian guide ranges only, dependent on a site inspection and formal written quote.

A quote that lands well outside these bands isn’t automatically wrong, larger, steeper or badly damaged slabs genuinely cost more, but it’s a good prompt to ask why. A quote that sits suspiciously below the range, with no mention of grinding, crack repair or a named sealer product, is more often explained by missing scope than by a genuine bargain.

What should be written into the formal quote?

A verbal number isn’t a quote. Before you agree to anything, ask for it in writing, covering:

• Scope of work: exactly what surfaces are included, and what prep steps are covered
• The product system: the actual coating and sealer brand or type being used, not just “resurfacing”
• Colour and finish: confirmed, ideally with a sample, not just a verbal description
• Timeframe: how many days on site, and when you can walk and drive on it afterwards
• What happens with hidden damage: the process for extra cracks, sunken sections or a failed old coating discovered once cleaning starts
• Payment terms and any warranty on workmanship

If a contractor is reluctant to put any of this in writing, that reluctance is itself an answer.

What should you ask about the day of the job?

It’s worth understanding what to expect before the crew arrives, not on the morning itself. Reasonable questions include how the area will be prepared and protected (garden beds, garage contents, cars), roughly how long the job will take from start to finish, and when you’ll actually be able to use the surface again. Our guide on what happens on resurfacing day walks through a typical job from arrival to clean-up, so you can compare what a contractor tells you against what a properly run job usually looks like.

Ten questions to take into every quote conversation

Print this list or keep it on your phone when contractors come to inspect:

1. What’s your licence number and which work does it cover?
2. Can I see your public liability insurance certificate?
3. What exactly does your prep involve for this slab?
4. Are you grinding back old coatings, or coating over them?
5. Which sealer system are you using, and is it coastal-rated?
6. What’s included in the price, and what’s an extra?
7. What happens if you find hidden damage once you start?
8. How long will the job take, and when can I drive on it?
9. Is there a warranty on the workmanship?
10. Can I get all of this in writing before I commit?

Any contractor who answers these clearly and without defensiveness has just told you most of what you need to know.

A word on honesty in this industry

Under the Australian Consumer Law, businesses cannot make false or misleading claims, including invented reviews, fabricated ratings or overstated experience. It’s a low bar, and every legitimate contractor clears it easily, but it’s worth knowing as a homeowner because it means you’re entitled to ask a contractor to substantiate what they tell you. On our side, Central Coast Concrete Revival publishes no fake reviews and no invented job counts: every job is arranged through, quoted by and completed by an appropriately licensed local contracting partner, and we say so plainly rather than dress up how the model works.

Questions to Ask a Concrete Resurfacing Contractor FAQs

What’s the single most important question to ask a concrete resurfacing contractor?

If forced to pick one, ask what their prep involves for your specific slab. Prep, not the finish coat, is what determines whether the job still looks good in five years, and a contractor who answers with specifics (grinding, crack treatment, oil-spot handling) is a stronger signal than any other single question on this list.

How do I check if a concrete contractor is actually licensed in NSW?

Ask for the licence number directly and verify it against NSW Fair Trading’s current records, since thresholds and categories are set and updated by that regulator and can change over time. A legitimate contractor will provide their licence number without hesitation and won’t mind you checking it independently.

Why do concrete resurfacing quotes for the same driveway vary so much?

Almost always it comes down to what’s included, not what’s being charged unfairly. A quote covering diamond grinding, crack repair and a coastal-grade sealer will cost more than one that amounts to a pressure clean and a coat of paint, and it will last considerably longer. Comparing scope line by line, rather than just the total, is the only reliable way to judge value.

Should I get more than one quote before hiring a resurfacing contractor?

Getting a second opinion is reasonable, particularly if the first quote is vague about prep or the sealer system, or if it sits well outside the indicative ranges published in our cost guide. Comparing quotes is only useful once you’re comparing the same scope of work, which is exactly what the questions on this page are designed to surface.

What should I do if a contractor won’t put the quote in writing?

Treat it as a genuine red flag. A written, itemised quote protects both sides: it sets out scope, product, colour, timeframe and what happens if hidden damage turns up, and it’s the document you’d refer back to if anything about the finished job doesn’t match what was agreed. Reluctance to provide one is reason enough to keep looking.

Does Central Coast Concrete Revival do the resurfacing work itself?

No. Central Coast Concrete Revival is a local lead-generation and marketing brand: enquiries are passed to an appropriately licensed local contracting partner, who inspects the concrete, provides the formal quote and completes the work. We describe the model this way because it’s the honest description of how it operates, and it’s exactly why the questions on this page matter before you commit to anyone.
