House Washing Tips for Wellington
Wellington's strong winds and driving rain cause salt deposits and grime to build up rapidly, particularly on elevated and exposed hillside properties.
Steep hillside sections common in Wellington suburbs create access challenges that can add to the final cost.
Wellington operators are experienced with the city's diverse housing stock from Victorian villas to modern townhouses.
House Washing in Wellington -- What to Know
Surface selection matters
Different cladding types in Wellington need different techniques. Render and painted surfaces need soft wash. Brick may tolerate medium pressure. Using the wrong technique causes damage that is expensive to repair.
Biocide treatment
Post-wash biocide applied to walls and roofs significantly extends the time before mould returns. Ask whether it is included in your quote or priced separately -- it affects the long-term cost significantly.
Bundling saves money
Most operators in Wellington charge a call-out fee that makes single-item jobs expensive. Bundling house wash with driveway, deck and roof in one booking reduces the effective per-surface cost.
What Changes House Washing Prices in Wellington?
Cladding type and contamination in Wellington
The type of cladding and level of contamination is the biggest pricing variable in Wellington. Clean render with light dust washes quickly. Heavy mould, black algae and lichen on rendered or painted surfaces requires more time, chemical treatment and careful technique.
Access and property layout
Single-storey properties in Wellington are the most affordable to wash. Two-storey homes, tight side access, steep blocks and elevated roof areas increase setup time and may require extension equipment.
Biocide treatment and sealing inclusions
Biocide treatment after washing slows mould and algae regrowth significantly. This extends the clean period and is particularly valuable on shaded walls and south-facing elevations in Wellington. Confirm what is included in each quote before comparing.
Water supply and equipment type
Operators using on-site water supply in Wellington typically quote less than those bringing water tanks. Commercial-grade soft wash equipment with chemical injection systems produces better results on delicate surfaces.
