Roof Cleaning (roof treatments and roof washing)

Moss, lichen and mould break down your roofing material fast, and once they take hold they're hard to shift. We offer two options: a roof treatment that naturally kills growth over time, or a full wash and treatment that gets your roof looking clean straight away and keeps it that way for at least 2 years. From a 20m² shed to a roof the size of 12 rugby fields, we've got it covered.

Hot Water Blasting

Greasy workshop floors, oil-stained concrete, chewing gum stuck to car parks and sidewalks. Cold water blasting won't touch it, and can etch softer concrete trying. We heat water to 90°C to cut through grease, oils and gum without chemicals, leaving surfaces sanitised and dry faster. Both pull from the specifics already in the full page description (the 90°C detail, the etching risk, the sanitised/no-chemical points) rather than the vaguer "just the ticket" and "really need some grunt" phrasing in the current version.

Concrete and Deck Washing in Northland and Auckland

Hard surfaces collect grime, moss and algae fast, and once they do, they age everything around them. We use soft washing or pressure washing depending on the surface, treating before and after the wash so the clean lasts months rather than weeks. Driveways, paths, decks, patios, car parks and large concrete areas across Northland and Auckland, with telescopic reach up to 15 metres for walls and building facades.

Cleaning & clearing blocked gutters on house in Whangarei

Gutter Cleaning and Blocked Downpipes

The most important thing you need to do to protect your house from water invasion via gutters is to keep them clean and clear. If left unattended, blocked gutters can cause quite a bit of expensive damage. Maintaining the health and flow of your gutters is a critical part of the autumn and winter jobs. Schedule us in at least once a year to remove plants and other debris from your gutters.

Solar Panel Cleaning

Dirty solar panels lose efficiency fast. You could be losing up to 20% energy output with just one year of buildup, and 35% if they haven't been cleaned in two years. We use a pure water-fed pole system with a soft brush, chemical-free, streak-free, and safe for all panel types. Bundle with your house wash and sort it all in one visit.

Motorhome & Caravan Washing

Your motorhome or caravan is your home on wheels. We wash it properly using a foam pre-wash, soft brush agitation, and a low-pressure rinse safe on all surfaces, including painted aluminium, fibreglass, windows, trims, and solar panels. Every wash includes a ceramic coating as standard, protecting against UV, salt air, and road grime. From $180 incl GST. Available across Whangarei, Kerikeri, Bay of Islands, Mangawhai, Dargaville, and the Far North.

Pro-grade bug and spider treatment

Most bug sprays use an off-the-shelf product in a knapsack sprayer. Ours doesn't. We use professional-strength actives that aren't available at the hardware store, applied with a precision mister system that gets into every spot bugs actually hide and travel through. We invested in specialist training to use this product properly. Protection lasts 3 to 6 months, safe for families and pets once dry.
