Concrete cleaning · Queenstown & Wanaka
Concrete cleaning done with chemistry, not just pressure.
Driveways, patios, garages and commercial slabs across the Southern Lakes. Specialist chemistry that lifts oil, lichen and weathering — without the high-pressure blasting that wrecks the surface you're trying to restore.

The concrete we work with
Every surface has its own treatment.
Driveways
Most Queenstown and Wanaka driveways are exposed aggregate or broom-finish concrete. Both pick up tyre marks, oil, lichen and alpine grime that water alone won't shift. We use chemistry that lifts the contamination, then a low-pressure rinse — never high-pressure blasting that erodes the cement paste between the stones.
Patios & paths
Pavers, broom-finish concrete and exposed aggregate paths around alpine homes get heavy moss, lichen and algae build-up where shade and irrigation overlap. Our biocide treatment kills spores so the green doesn't grow back in a season.
Garage & workshop floors
Oil, hydraulic fluid, rust and tannin staining on garage and workshop slabs. Specialist degreasers and stain-specific chemistry — what works on oil doesn't work on rust, and vice versa.
Exposed aggregate
Exposed aggregate looks beautiful when clean and shabby when neglected. The aggregate stone holds dirt in its micro-texture. We deep-clean the matrix without smoothing the surface or stripping the existing seal.
Commercial slabs
Café forecourts, restaurant terraces, retail entrances. After-hours work, no disruption, results that hold up to alpine UV and freeze-thaw cycles.
Pool surrounds & alfresco areas
Concrete around pools and outdoor entertainment areas needs a clean that respects the slip-rating and any existing sealer. We choose products that don't strip the finish you paid for.
How we work
Slow when it matters, fast when it doesn’t.
01
On-site assessment
We look at the substrate, the staining, and any existing seal. A small spot-test tells us what method the surface actually needs — high-pressure blasting is rarely the right answer for concrete.
02
Targeted chemistry
Oil, rust, tannin, lichen, weathering — each needs a different cleaner. We carry a full chemistry kit and choose by stain type, not by habit.
03
Low-pressure rinse
We rinse with the lowest effective pressure. High-pressure blasting on concrete strips the cement paste between aggregate stones and accelerates wear.
04
Optional sealing
Clean concrete is the right time to seal. A penetrating sealer locks in the result and stops the next round of staining before it starts.
