SERVICING OAMARU, DUNEDIN TO MILTON & BEYOND
PROFESSIONAL OAMARU STONE CLEANING & SEALING
Oamaru stone and natural stone surfaces require specialist care. Over time, dirt, moss, mould, algae, and weather staining build up on stonework - leaving homes, walls, pathways, and buildings looking aged and neglected.
At Blast Off Otago, we provide professional Oamaru stone cleaning and sealing services throughout Otago. Using safe soft washing methods and specialist stone treatments, we carefully restore the natural appearance of limestone and other delicate stone surfaces without causing damage.
From historic Oamaru stone homes to modern stone cladding and entranceways, we help bring surfaces back to life while protecting them long term.

Once cleaned, sealing your stonework is the best way to keep it protected from Otago’s harsh weather conditions.

We use high-quality breathable sealers designed specifically for natural stone and limestone materials.
Why Seal Your Concrete in Dunedin?
Oamaru stone is a soft limestone material that can easily be damaged by incorrect pressure washing or harsh chemicals. Using the wrong cleaning methods can permanently mark, erode, or weaken the surface.
Our cleaning process is designed specifically for delicate stone surfaces, ensuring a safe and effective clean without unnecessary damage.
With Otago’s wet winters, coastal air, and strong UV exposure, regular maintenance and sealing can dramatically improve the lifespan and appearance of your stonework.
