Hamilton & the Waikato
Roofs, spouting, houses, driveways and decks — washed by a Hamilton crew with 14 years on the tools.
Our policy
Three rules decide what happens at your place, and the order is the whole point.
You, anyone else at the property, and the person doing the work. That is settled before the job is, every time.
Cladding, paint, roof, joinery, plants and paving. We would rather leave a stubborn mark than take your paint off getting rid of it.
With a mix and a pressure chosen for your surfaces, so the first two still hold once we have finished.
20% off when you book two or more services There’s a further package discount on bigger jobs — worth asking about when you get your quote.
Most people get two or three done on the one visit — which is where the 20% comes in.

Why people ring us
Nearly everyone who calls us used to do it themselves, and did a good job of it. Then the roof got steeper, or the knees got older, or there was one wobble at the top of the ladder.
You keep the garden and the jobs you enjoy. We’ll take the gutters, the roof and the two-storey wall nobody should be reaching.
“I’m past getting up on the ladder.”
Most companies make you book a visit before they’ll tell you anything. Here are our starting prices, so you can work out whether we’re in your ballpark before you pick up the phone.
Your exact price is confirmed in writing at the free quote, before any work starts. Book two or more services and the 20% comes off the lot.
How it works
That’s genuinely it. Three steps, and the first one takes a minute.
Your address and roughly what you’re after. Not sure what you need? That’s most people. Send the form instead if it’s late and you’d rather not ring.
About fifteen minutes, all of it outside. Nobody needs to come indoors.
Worked out for your property, not read off a chart, with the 20% already taken off if you’re having two or more services done.
On the day, the person doing the work introduces himself and walks you through what’s happening before he starts.
What we actually use
Houses get a biodegradable mix at low pressure, so the paint stays on the wall. Concrete gets proper pressure. Timber gets treated gently. Matching the method to the surface is the whole job.
Before we start we soak down the garden beds and lawn beside whatever we’re washing, and we rinse them off again at the end. Water dilution is what actually protects your roses. Pot plants, outdoor furniture and anything precious, we move or cover with you first rather than guess.
Pets and kids indoors or round the other side while we work, and back out as soon as we’ve rinsed down.
We’d rather tell you that than take your money.
Then you probably don’t need a house wash, and we’ll say so. On a brick home the work is nearly always the roof, the spouting and the driveway.
Leave the walls alone for now. But the spouting has still been filling up all year, and a fresh paint job is exactly the thing worth protecting from an overflowing gutter.
We don’t replace spouting, but we’ll tell you honestly whether yours needs replacing or just needs clearing. Quite often it’s just clearing, and that saves you a packet.
Roofs usually do. Moss and lichen sit in the hollows and on the shaded side, which is where they hold water and start overflowing in heavy rain. We’ll show you photos of yours.
Before and after
Same house, same angle, taken on the job. We photograph gutter work before and after as standard, because you can’t see inside your own spouting from the ground.
Where we work
Actual suburb names, not “your area”. We plan the week street by street, so there’s usually a day already heading your way.
Ring and ask. We get out to Tamahere, Cambridge, Te Awamutu, Ngāruawāhia, Horotiu and further round the Waikato often enough that it’s worth the call. If we can’t get to you we’ll say so on the phone, not after you’ve filled in a form.
It’s how we get the moss and lichen off your roof without anyone scrubbing it. We spray the whole roof with a treatment that kills the moss, lichen and mould at the root. It dies off over the following weeks and the rain carries it away, so the roof keeps getting cleaner after we’ve gone.
It’s the gentlest way to do it. A roof that gets blasted with high pressure can end up with cracked tiles, lifted ridge caps and water pushed up under the laps. And the moss comes straight back anyway, because blasting only takes off what you can see.
More people ask us this than anything else, so the answer is a long one.
The mix is biodegradable and it goes on at low pressure. Before we start we soak down the garden beds and the lawn beside whatever we’re washing, then rinse them off again at the end. Plain water dilution is what actually protects your planting. Pot plants, outdoor furniture, anything you care about: we’ll move it or cover it with you first rather than guess what matters.
Pets and grandchildren indoors while we work, or round the other side. They can come back out the moment we’ve rinsed down.
We stay off it wherever we can, and treat the roof from the edges and off ladders. Some roofs do need someone up there. If yours is one of them you’ll hear it at the quote, not on the day.
If you have solar panels we spray around them, not over them, unless you ask us to. There’s wiring under there we’d rather not disturb.
Most jobs start at $200. A roof treatment on a standard 180 m² single-storey roof starts at $250.
We are not the cheapest and we won’t pretend to be. Book two or more services and 20% comes off the lot, because one visit costs us less than two. Your exact price is confirmed in writing before anything starts. See how our pricing works.
Not unless you want to be, and plenty of people do. The quote is done from outside and takes about fifteen minutes. Nobody needs to come inside your house at any point, for the quote or for the job.
Probably not, and we’ll say so. Brick and mud brick mostly look after themselves, and we aren’t going to charge you for washing something that doesn’t need it.
What we’d look at on a brick home is the roof, the spouting and the driveway. That’s usually where the work actually is. Same if you have just had the place painted: the paint is fine, but the gutters have still been filling up all year.
If you’re still happy up the ladder, good on you. Genuinely. Most people who ring us have simply got to the point where being three metres up with a hose is no longer a sensible way to spend a Saturday, and the spouting has quietly gone two or three years without a clear-out.

Most people we look after are on a yearly or two-yearly cycle. Spouting is worth clearing once or twice a year, especially under pines or big deciduous trees. A roof treatment holds for a good year or two. Houses in the shade, down the south side, or near the coast go green faster than everything else.
Autumn is the best time to get it sorted, before the weather turns and while we can still get a dry run at it.
Give us the address and whatever you can see from the driveway. Moss on the roof, green down the south wall, spouting spilling over every time it rains. We’ll come and price it properly, from outside, in about fifteen minutes.
