House Wash

Wash the grime off, not the paint.

A low-pressure soft wash for the whole outside of the house. We treat the mould, algae and grime on your cladding, soffits, joinery and spouting faces, then rinse it all off gently, top to bottom.

Soft washing, in one breath

The solution does the scrubbing.

We put a cleaning solution on at low pressure, give it time to work on the mould, algae and grime, then rinse the lot off gently, top to bottom. Closer to a garden hose than a blaster.

Why not just blast it? High pressure can strip paint, chew up soft timber and force water in behind the cladding, into the wall cavity, where it can sit and cause rot you won't see.

Why not just hose it? Resene says a quick rinse with plain water won't remove the spores. You need a proper cleaning solution, and that's the bit we bring.

What we wash

Whatever your house is wearing.

Different cladding, different care. The ticks are a straight soft wash. The ones marked extra care get a gentler hand, the way their makers ask.

Weatherboard

The classic Kiwi house. Low pressure only, because a blaster can strip paint and push water in behind the boards. Wattyl advises against high pressure water blasting on stained and oiled timber too.

Fibre cement

Linea and other fibre cement boards. James Hardie's own care guide says wash it with low pressure water and a brush, and don't use a water blaster on the cladding.

Brick

Tough as, but it can grow a white, powdery salt bloom called efflorescence. A brush and a careful rinse come first. Strong acid cleaners can burn the brick and etch the mortar.

Plaster, texture coat & EIFS

Extra care. Low pressure with the nozzle held well back, and a gentle cleaner. Too much pressure can strip the finish coat and let water in behind it, risking the layers underneath. Solvent cleaners are out.

Natural cedar

Extra care. Cedar's a soft timber, so high pressure or harsh bleach-based cleaners can roughen the grain and strip its natural oils. Cedar care guides suggest a gentle wash or hose-down once a year. Confirm: do you wash cedar, and with what?

Steel cladding

Extra care. NZ Steel's guidance is to wash steel walls by hand with water and a sponge or soft brush, more often the closer you are to the coast, with extra attention on sheltered spots the rain never reaches. Confirm: your method on steel

In the wash

The whole outside, top to bottom.

  • Every bit of cladding, washed from the top down.
  • Soffits and fascia, the sheltered bits under the eaves that rain never rinses.
  • Window frames and joinery.
  • Spouting faces and the downpipes you can see.
  • Confirm: does the window glass get a rinse as standard?
Separate jobs

Not part of a house wash.

  • The inside of your gutters. That's a Gutter Clean.
  • Moss and lichen on the roof. That's a Roof Treatment.
  • Paths, driveways and decks. That's Surfaces.
  • Fixing leaks, rot or flaking paint. A wash is a clean, not a repair.
  • Confirm: is a proper streak-free window clean an add-on, or not offered?
Before & after

Same wall, same spot, one wash apart.

After: the same weatherboard wall, same spot, freshly soft washed
Before: the shady side of a house, green and grubby
Before
After

Placeholder: shoot your greenest wall before and after, from the exact same spot. The south side is usually the winner.

Don't just take our word for it.

Paint and cladding makers publish care guides, and they're pretty clear about washing.

What the paint makers say

Washing is part of looking after your paint

Resene says it's important houses are washed each year, to keep the paint looking good and to get rid of the salt deposits, bird droppings, mould and other muck that can affect the coating.

Dulux suggests washing exterior paintwork every one to two years in sheltered or inland spots, and as often as every six months in coastal or industrial areas, using a low pressure water wash plus a soft brush on stubborn dirt. James Hardie says to wash Linea weatherboard every 6 to 12 months, or every 3 to 4 months in extreme coastal or sea spray conditions. Near the sea? That's worth knowing.

Some warranties lean on it too. Resene's paint warranty for Linea lists washing every 6 to 12 months as basic maintenance, and COLORSTEEL's warranty terms tie keeping the warranty valid to sticking to its washing schedule.

Warranty terms vary from product to product, so we can't tell you what yours needs. Dig out the paperwork for your paint or cladding and check what it asks for. Confirm: will you give customers a dated invoice or wash record for their warranty files?

How a house wash goes

Top to bottom, no blaster.

01

Send photos You

Your address and a few photos through the form. Know what the cladding is? Tell us. If not, a close-up does the job.

02

Walk round

We check what your house is clad in and look for anything loose, cracked or flaking before a drop goes on. Windows and doors get shut.

03

Garden first

Beds and plants along the house get a good soak with plain water first, so they're not thirsty for wash solution. Confirm: your plant protection routine

04

Treat

The solution goes on at low pressure from the top down, over the cladding, soffits, fascia and spouting faces. Then it gets time to work. Confirm: your usual dwell time

05

Rinse

Everything gets rinsed off top to bottom at low pressure, then the garden beds get another rinse to dilute any runoff.

06

Last lap

A final walk round for streaks or missed spots before we pack up. Confirm: do you send before and after photos?

House wash questions.

Will a soft wash damage my weatherboards or paint?
Soft washing is the low-pressure approach cladding and paint makers point people towards, because high pressure can strip the paint film or force water in behind the boards. What a wash can do is show up paint that's already tired. If it's flaking or chalky, we'll point it out before we start.
How often should I get my house washed?
The paint makers mostly say every year or two, and more often near the sea. Dulux suggests as often as every six months in coastal areas, and James Hardie says every 3 to 4 months for Linea in extreme sea spray. Shady walls tend to need it sooner too. We'll tell you honestly what yours needs.
Will washing keep my paint warranty valid?
It can help. Some warranties list regular washing as basic maintenance, like Resene's paint warranty for Linea weatherboard. Terms vary by product though, so check your own paperwork for exactly what it asks for.
Is the wash solution safe for my garden and pets?
Soft wash solutions are commonly based on sodium hypochlorite, the active stuff in household bleach, and they can harm plants if the runoff isn't managed. Good practice is to soak garden beds with plain water first, cover anything precious, rinse everything well afterwards, and keep people and pets clear while the work's underway. Confirm: the product you use, how you protect plants, and when pets can come back out.
Do you do the windows?
The frames and joinery get washed with the rest of the house. Confirm: whether the glass gets a rinse as standard, and whether a proper streak-free window clean is an add-on.
How long does a house wash take?
Confirm: a typical time for an average single-storey house (other NZ operators commonly quote 1 to 3 hours).
Will a wash fix a leak or a damp wall?
No. A wash is maintenance, not a repair. The building code guidance does count washing as part of looking after cladding, but it also notes a tired-looking wall isn't necessarily a leaky one. If anything looks like a leak, rot or damage, get a builder to check it. If we spot something on the day, we'll tell you. Source: building.govt.nz, E2/AS1 external moisture
