The difference speaks for itself. Real homes, real results. From stained driveways to weathered roofs — see what a proper clean looks like.
We clean timber decks, composite decking, painted decks, stained decks, and all common fence types including timber, Colorsteel, PVC, and painted fences. Our deck and fence cleaning methods are adjusted to suit each surface for safe, effective results.
Yes. We use soft wash deck cleaning and low-pressure water blasting methods that are specifically calibrated for each surface type. Timber and composite decks require different pressure settings and solution concentrations — we assess each deck before starting to ensure we clean effectively without raising wood grain, splintering timber, or damaging composite board surfaces. High-pressure blasting on composite decking, for example, can void manufacturer warranties, which is why we always use controlled, surface-appropriate methods.
Yes. Removing algae, mould, lichen, and slippery organic growth is the primary reason most customers book a deck clean. Our pre-treatment solution breaks down biological growth at the root level — not just surface removal. After treatment and cleaning, the surface is safe to walk on and significantly less prone to rapid regrowth. If you've noticed mould on your decking or green algae making the surface slippery, this is the most common and urgent reason to book.
Yes. We adjust our cleaning approach based on your fence type and its current finish. For painted or stained fences, we use lower pressure and wood-safe cleaning solutions to remove dirt, mould, and grime without stripping or damaging the existing coating. For bare timber fences, we can clean more thoroughly and prepare the surface for a new stain or sealant if required.
Most New Zealand decks and fences benefit from a professional clean every 1 to 2 years. Properties in Auckland, Hamilton, and Tauranga that are shaded, near trees, or close to water will accumulate mould and algae faster and may need annual cleaning. Decks that are regularly walked on in damp conditions also degrade more quickly. After cleaning, applying a quality deck stain or sealant will extend the time between cleans and protect the timber year-round.
Yes — and cleaning is the essential first step before any staining or sealing. Clean wood absorbs stain evenly and holds it for longer. Staining over dirty or mouldy timber results in a patchy finish and premature failure of the coating. Our brightening treatment step prepares the surface specifically for staining or sealing. If you're looking for fence cleaning and staining, or deck cleaning and staining services, we can prepare your surfaces to the standard required for best results. Contact us to discuss a cleaning and staining preparation service.

Yes. We safely clean large, multi-level, or elevated decks and fences using professional equipment tailored to each property, including tricky or hard-to-reach areas.
Yes. Many customers in Auckland, Hamilton, and Tauranga combine deck and fence cleaning with house washing, roof treatment, gutter cleaning, or driveway cleaning for a complete exterior refresh.
In New Zealand's climate, the general guideline is every 1 to 2 years for most properties. However, properties in the upper North Island — including Auckland and Tauranga — experience warmer, wetter conditions that accelerate biological growth on timber surfaces. Hamilton properties with heavy tree canopy often see faster moss and mould accumulation. For these regions, annual professional deck cleaning and fence cleaning is a sensible investment, particularly before the summer season when outdoor spaces get the most use.
