-
Oamaru Stone Cleaning & Sealing Our most Oamaru-specific service. Specialist soft wash cleaning for natural limestone surfaces — homes, walls, pathways, steps, and heritage structures. Cleaned using stone-safe low-pressure methods and sealed with breathable sealants formulated for porous limestone. We never use high-pressure washing on Oamaru stone.
-
Water Blasting Professional water blasting for driveways, paths, patios, concrete, fences, block walls, and all outdoor hard surfaces. Commercial-grade equipment and the right technique for each surface type.
-
House Washing Full exterior soft wash for residential and commercial properties in Oamaru. Safe on all cladding types including plaster, timber, brick, and stone. Removes mould, algae, grime, and coastal salt deposits from the full exterior.
-
Roof Cleaning Soft wash moss, lichen, and algae removal from residential roofs across Oamaru, with professional roof treatment applied after the clean. Oamaru's coastal position and high rainfall make regular roof maintenance particularly important for protecting roofing materials.
-
Gutter Cleaning Complete debris removal and downpipe flushing for residential and commercial properties. Oamaru stone dust and coastal debris create their own type of gutter accumulation — we clear it all and remove debris from site.
-
Concrete Cleaning & Sealing Driveway, path, and outdoor concrete cleaning with sealing available to protect against Oamaru's coastal conditions and slow moss and algae regrowth.
-
Deck & Fence Cleaning Controlled-pressure timber cleaning for decks and fences, including preparation for staining or recoating.
-
Drain Clearing Outdoor stormwater drain unblocking and drainage system flushing for residential and commercial properties.
