Façade & Cladding Wash: Keeping Your Auckland Home's Exterior Fresh

The cladding is the single biggest visible surface on your home — and in West Auckland, it takes the most punishment from salt, damp, and bush debris. With 7+ years of experience washing every type of cladding from plaster to cedar, Fizzy Cleaning has cracked the code on what works safely, and what destroys your paint film in one afternoon.

Know Your Cladding Type Before You Wash

Each substrate needs a different approach. Painted weatherboards (the classic Henderson villa look) need gentle soft wash with a mild detergent. Brick needs careful control of pressure and dwell time. Plaster-over-polystyrene (common on 2000s townhouses) is fragile and never tolerates water blasting. Cedar requires pH-neutral products so you don't strip the natural oils. Fibre cement board (Linea, Hardies) is tougher but still benefits from soft wash over high pressure. For a complete overview, start with our exterior house cleaning guide.

Why Soft Wash Beats Pressure Every Time

High-pressure water forces moisture behind cladding joins, under flashings, and into cracks in paint. Even one careless pass can let enough water in to trigger mould behind the gib sheet. A proper soft wash uses volume, not pressure — combined with a surfactant that breaks down grime chemically. The same logic applies to your roof; we break that down in our roof moss removal article.

Common Auckland Problems You'll See Solved

A professional facade wash removes black algae streaks (especially on south-facing walls), green moss patches near gutters, spider webs under eaves, lichen spots, salt haze on coastal homes, and the general grey dullness that sets in after a few Auckland winters. You'd be amazed how much colour your cladding actually has under the biofilm.

Protecting Plants, Pets, and Neighbours

Good crews tarp garden beds, pre-wet foliage, flush soil post-wash, and schedule around your pets and neighbours' washing lines. Chemicals are biodegradable and broken down within hours — this isn't 1990s pressure-washing with bleach. We also avoid windy days to keep overspray off neighbouring properties.

How Often and When

For most West Auckland homes, a full facade wash every 12 to 18 months keeps paint warranties valid and extends coating life by years. Homes in shaded valleys or near native bush may need annual service. Coastal homes benefit from a lighter freshwater rinse between full washes. We're 24/7 available, Henderson-based, and can combine your facade wash with gutter cleaning for a discounted bundle rate.
