Working in Wanaka
The local conditions that change how we work.
Wanaka limestone gets a particularly harsh ride. Higher UV than Queenstown, harder frosts further from the lake, longer dry summers. Each pulls the stone in a different direction — UV fades the surface, frost cycles open the pore structure, dry summers bake biological growth in deep. Combined effect: a limestone surface that looks weathered in 10-15 years instead of 30-40. The right cleaning approach, paired with proper sealing afterwards, can reset that clock significantly.
Whether it's a residential job, a commercial site or a heritage building, we adapt our method to the surface, the exposure and the season. Our team is on the ground in Upper Clutha weekly, call-outs to Wanaka are part of the normal schedule, not a special trip.

Wanaka FAQs
Common local questions.
Do you work on Ōamaru stone homes in Wanaka or just Queenstown?
Both. We're in Wanaka every week and a significant share of our limestone work is in the Upper Clutha.
My Ōamaru stone has gone green on the shaded side — can it be cleaned without damaging it?
Yes. Green is typically algae or moss, both of which lift off with the right biocide. The trick is using a treatment that's strong enough to kill the spore base but pH-balanced for limestone. Standard moss killers from a hardware store can etch the stone.
Will cleaning remove the patina I actually like?
Honest answer: it can. We'll talk through what you want to keep before we start. Some clients want the natural weathered look preserved and just want the biological growth removed; others want a deeper restoration. We can do either.
How much does cleaning Ōamaru stone cost in Wanaka?
We quote in person because the cost depends heavily on the size of the wall, the height (scaffolding adds cost), and the level of biological growth to remove. A small feature wall might be a few hundred dollars; a full house façade is a multi-day job. Quotes are free.
