Horowhenua

Horowhenua's growing. So's the green stuff.

House washing and soft washing right across Horowhenua, from Foxton Beach down to Manakau. We treat the mould, algae and lichen at low pressure, then rinse it away, whether you're in the middle of Levin or out behind the dunes.

Where we wash

All of Horowhenua, not just Levin.

Levin's the big one, but the district runs from the dunes at Foxton Beach to the nurseries around Manakau, with beach settlements, small towns and lifestyle blocks in between. That's our patch.

It's a district on the move, too. Horowhenua grew about 10 percent between the 2018 and 2023 Censuses, and the council says that makes it the 10th fastest-growing district in the country. Construction on the Ō2NL highway, between Ōtaki and north of Levin, started in late 2025, with completion expected in 2029.

New house or old, weatherboard or brick, they all cop the same weather. Give it time and the green stuff tends to turn up, and that's where we come in.

Inland vs coast

Inland or by the beach, it still goes green.

Inland, it's damp and sheltered. Out at the beach there's less rain on paper, but you've got salt and sand to deal with. Different reasons, same green walls.

Inland

Sheltered, so it stays damp.

  • NIWA's records for Levin show about 1,160 mm of rain a year, with 1 mm or more falling on roughly one day in three.
  • It's sheltered, too. NIWA puts Levin's mean wind speed at about 10 km/h, against nearly 18 km/h at Ohakea, which is more exposed to the west.
  • The metal roofing industry's code of practice says sheltered, shady spots are where lichen does best. So the shady side of a house or roof is often the first to go green.
  • Resene says a quick wash with water won't remove the spores and a chemical treatment is needed. That's the idea behind a soft wash.
On the coast

Out where the wind brings the salt.

  • Foxton Beach and Waitārere Beach sit on New Zealand's largest coastal dune system, which runs from Pātea down to Paekākāriki. The council's district plan talks about "sand blow" at both.
  • Less rain on paper. NIWA's Himatangi station, the nearest it lists to Foxton Beach, averages about 840 mm a year. But the prevailing wind comes from the west, off the sea, and NIWA says settled weather brings pronounced sea breezes in summer.
  • Salt builds up. Resene says to wash a house every year, partly to shift salt deposits, and the metal roofing code says metal surfaces that miss out on rain or hand washing may corrode two to three times faster than cleaned ones.
  • BRANZ puts anywhere within 500 m of the coast, or 100 m of a tidal estuary, in its high-risk salt zone, Zone D, for building fixings. Foxton Beach sits at the Manawatū River mouth, so it's worth checking your address on BRANZ Maps.

Levin

The big one. About 19,500 people lived here at the 2023 Census, over half the district.

It sits inland, out of the worst of the wind, and it's damp enough for moss, mould and lichen to settle in. It's on council water, so if restrictions kick in they can shift booking dates.

East of town, the council's Tara-Ika rezoning took effect in March 2024. The area is zoned for around 3,500 new homes over the years ahead. Block of units or a body corporate site? Have a look at commercial.

Foxton Beach

About 2,100 people at the 2023 Census, at the mouth of the Manawatū River. The council's district plan describes a holiday and retirement town with a high proportion of holiday homes and baches, wide open streets, and a coastal landscape of dunes and "sand blow".

A bach you only see at Christmas has nobody around to notice the green creeping up the walls. Confirm: can you wash a bach while the owners are away, with access sorted first?

Foxton

About 3,400 people at the 2023 Census, roughly 6 km in from Foxton Beach and on council water. Like the rest of the coast, the weather mostly rolls in from the west.

Shannon

About 1,500 people at the 2023 Census, around 15 km north-east of Levin. Far enough inland that salt isn't the main worry. Damp and shade are.

Waitārere Beach

Just under 1,000 people at the 2023 Census, up nearly 30 percent on 2018. The council's district plan calls it distinctly coastal, with considerable sand blow and a large number of holiday homes.

It isn't one of the council's water supplies, either. The 2015 plan says water here comes from individual roof supply and groundwater bores, so if yours fills a tank, read this first.

Ōhau

About 770 people at the 2023 Census, just south of Levin. The district plan describes a low-density rural township, with sections mostly over 1,000 square metres and lifestyle blocks growing around it. It's not on the council's list of drinking-water supplies, and the plan says water is generally provided on each site, with only a limited supply from Levin. So tell us if your roof fills a tank.

Manakau

About 480 people at the 2023 Census, at the southern end of the district, roughly 12 km south of Levin. Rural, with nurseries and horticulture, and off the council's water supplies too.

Out past the town supply?

Lifestyle block or beach place running on its own roof water? Then there's a bit more to treating the roof. Here's how it works.

Tank water, explained

Census counts are from the 2023 Census (Stats NZ), rounded. Levin, Foxton, Foxton Beach and Shannon come from Horowhenua District Council's census breakdown. Waitārere Beach, Ōhau and Manakau are Stats NZ settlement figures as reported on Wikipedia (Waitārere Beach, Ōhau, Manakau). Other details: the Horowhenua District Plan 2015, the council's water supplies, Plan Change 4, Tara-Ika (with the council's Tara-Ika news for the housing figure), and Wikipedia on Foxton, Foxton Beach and Shannon. Confirm: check these Census counts on Stats NZ's place summaries before launch.

Off the town supply?

On tank water? Tell us when you book.

Horowhenua District Council lists six drinking-water supplies: Levin, Foxton, Foxton Beach, Shannon, Mangaore and Tokomaru. Outside those, your water may well come off your own roof or from a bore. The council's 2015 district plan says Waitārere Beach homes rely on their own roof supply and groundwater bores.

If your roof fills a drinking-water tank, the pipe into the tank needs disconnecting before any roof treatment goes on. BRANZ's Level guidance says to disconnect it first and rinse everything down with clean water before reconnecting. The exterior cleaning industry's code of practice says treated roofs used for collecting water need the tank disconnected or diverted, so the water isn't tainted.

When to reconnect is where the advice differs. The same code says to stay disconnected through at least three or four separate rain events of more than 30 minutes each, and product labels may set their own rule. Confirm: your tank routine, including who disconnects and reconnects the downpipes, and the reconnection rule on your product's label.

There's more on this on our roof treatment page.

New build?

Brand new still goes green.

A new house might look fine for a while. But the people who make cladding and paint still set washing schedules, new or not.

James Hardie's care guide for its Linea Oblique weatherboard says to wash it every 6 to 12 months with low-pressure water and a brush, or every 3 to 4 months in extreme coastal or sea-spray conditions, and not to use a water blaster on it. Resene says houses should be washed every year to keep paint finishes looking right and get rid of salt deposits, bird droppings and mould.

Tara-Ika, east of Levin, is zoned for around 3,500 new homes over time, so there could be plenty of fresh cladding about. Check the care guides for your own cladding and paint, as each maker sets its own schedule. Confirm: do you offer scheduled repeat washes for newer homes?

Horowhenua questions.

Do you cover all of Horowhenua?
Levin, Foxton, Foxton Beach, Shannon, Waitārere Beach, Ōhau and Manakau, plus the lifestyle blocks in between. Hōkio Beach, Waikawa Beach or somewhere not on the list? Ask anyway, we'll tell you straight. Confirm: whether there's a travel charge for the beach settlements or the far ends of the district.
Does a house near the beach need washing more often?
Often, yes. Resene says every house should be washed each year, and that salt-blown spots the rain doesn't reach need particular attention. Dulux says its maintenance routine, which starts with a low-pressure wash, may be needed as often as every six months in coastal areas. James Hardie says every 3 to 4 months for its Linea Oblique weatherboard in extreme coastal or sea-spray conditions. Not every beach house is right in the spray though, so we'll tell you honestly what yours needs. Sources: Resene, Dulux paint care guide and James Hardie
What's this salt zone people talk about?
BRANZ maps exposure to wind-driven salt for choosing building fixings. Its high-risk zone, Zone D, includes the area within 500 m of the coastline and within 100 m of tidal estuaries and sheltered inlets. It's a building design zone, not a cleaning rule, and it's mapped address by address, so check yours on BRANZ Maps rather than guessing. Either way, it gives you a rough idea of how much salt your place might see. Source: BRANZ Bulletin 588
I'm on tank water. Can you still treat my roof?
It can be done, with the pipe into the tank disconnected first and left off until the roof's been properly rinsed. Tell us when you book, and have a read of the tank water note above. Confirm: how much rain you wait for, and who reconnects the downpipes.
Can water restrictions affect my booking?
They can. Horowhenua District Council uses water restriction levels, and at the higher levels commercial exterior washing is limited or needs the council's approval first. If restrictions are on when your job's due, we may need to move the date. Source: Horowhenua District Council, water conservation and restrictions Confirm: re-check the council's current restriction table and how it applies to your gear and water source.
My house is brand new. Does it really need washing?
It might look fine for a while. But cladding and paint makers still set washing schedules, new house or not. James Hardie's Linea Oblique care guide, for one, says every 6 to 12 months. Check the care guides for your own cladding and paint, and we'll take it from there.

What can shift your date.

Rain

NIWA's Levin records show 1 mm or more of rain on roughly one day in three. The exterior cleaning industry's code says cleaning agents shouldn't go on when high wind or rain is forecast, so a wet week can push a job back.

Confirm: your rain policy, for example rebooking if heavy rain is forecast.

Wind

Levin's fairly sheltered, but the prevailing wind is westerly and NIWA says settled summer weather brings pronounced sea breezes. The exterior cleaning industry's code also says to hold off in high wind, and spray drifts anyway, so a gusty day can move things too.

Water restrictions

The council can bring in water restriction levels, and at the higher ones commercial exterior washing gets cut back or needs approval. Levin, Foxton, Foxton Beach and Shannon are all on council water.

Confirm: how restrictions affect your bookings, and whether you bring your own water.
