What to check before hiring garage floor resurfacing contractors: licensing, warranty, red flags, and the questions worth asking.
A quick search for garage floor resurfacing contractors turns up dozens of options, and on paper most of them look similar: photos of glossy floors, promises of a quick turnaround, competitive quotes. The differences that actually matter, licensing, warranty terms, the coating system used, only show up once you start asking the right questions. Here's what separates a contractor worth hiring from one you'll be calling back in two years.
Start with licensing. In Queensland, any contractor carrying out garage floor resurfacing as part of a building or renovation job should hold a current QBCC licence, and it's worth checking that licence rather than taking it on trust. Insurance matters just as much: if something goes wrong on your property, an uninsured contractor leaves you exposed. Beyond the paperwork, ask what warranty is offered and what it actually covers. A lifetime adhesion warranty is a meaningful commitment from a contractor confident in their prep work. A vague "satisfaction guarantee" with no specifics usually isn't.
A short conversation before you commit tells you most of what you need to know:
Most garage floor resurfacing jobs can be quoted accurately from a handful of clear photos, and that's a good thing: it's faster and cheaper for everyone, and it doesn't mean corners are being cut. Send photos showing the slab, any cracking, staining or old coatings, and a contractor who's seen enough garage floors should be able to put together an itemised quote without needing to visit first. What matters is what happens when something in the photos looks out of the ordinary, significant cracking, a sunken area, or anything suggesting a structural issue. That's when a proper contractor arranges an on-site look before locking in a price, rather than guessing. And regardless of how the quote was put together, moisture should always be tested on site on the day of the job, before any coating goes down. That step is what actually protects the floor long-term, and it's not one worth a contractor skipping to save time.
A few warning signs are worth taking seriously. A quote that's dramatically cheaper than every other one you've received usually means shortcuts somewhere, most often in slab prep, which is the step that determines whether the floor lasts fifteen years or fails within two. Pressure to sign on the spot, no fixed address or licence number you can verify, and an unwillingness to put the warranty in writing are all reasons to keep looking.
Brisbane's climate puts real demands on epoxy coatings that a contractor without local experience might not account for. Humidity affects cure times and can trap moisture under a coating if the slab isn't tested properly first. UV exposure fades or chalks a topcoat that isn't rated for it. A contractor who's resurfaced garage floors across Brisbane for years has already worked through these issues on other people's garages, not yours. That experience shows up in fewer callbacks and a floor that actually holds up to a Brisbane summer.
Hardware-store epoxy kits are tempting because they're cheap and look simple enough on the box. The problem is almost never the epoxy itself, it's the prep. Professional garage floor resurfacing contractors grind the concrete to open the surface and remove contaminants before anything goes down, which is what the epoxy actually bonds to. Most DIY kits skip this step entirely or rely on a light acid wash, and that's why so many DIY garage floors start peeling or flaking within a year or two. By the time that happens, the cost of doing it properly the second time, including removing the failed coating, often ends up higher than hiring a contractor from the start.
The contractors worth hiring tend to share a few things in common: a proper product system rather than a generic hardware-store epoxy kit, a track record you can actually verify with real addresses and real photos, and a same-day or close-to-it install process that reflects genuine efficiency rather than rushing the job.
