No two homes in New Zealand face quite the same cleaning problems. Living in Otago is very different from living in Wellington — and your roof, gutters and exterior walls prove it every season. From icy winters that fuel moss growth in Dunedin to salt spray blasting your windows in Wellington, our varied climates create unique cleaning challenges that every homeowner should understand.
If you’ve ever wondered why your neighbour needs roof moss removal every year in Otago, or why your Wellington windows never seem to stay clean, this guide is for you. We’ll break down the biggest cleaning headaches in each region — and explain how to tackle them, so you can protect your property and avoid costly repairs later on.
Why Your Region Dictates Your Cleaning To-Do List
One of the biggest reasons homes across New Zealand age so differently is the weather they face every day. If you own a house in Otago, you’re familiar with crisp mornings, heavy frosts and damp winters. These conditions are perfect for moss, mould and lichen to flourish on your roof and driveways. It’s why so many homeowners book regular roof moss removal in Dunedin and surrounding towns.
Wellington homes, on the other hand, battle wind, rain and coastal conditions. If you live near the sea, you’ll know how often salt spray sticks to cladding, windows and roofs. That’s why house washing in Wellington is so common — the wind leaves grime and salt behind that, if ignored, can damage paintwork and corrode metal over time.
Roof Cleaning: Stopping Moss and Salt Damage
In Otago, roof cleaning is less about general dirt and more about removing thick moss and lichen that cling to tiles and shingles. Once established, moss traps moisture, lifts roof materials, and can block gutters too. Many homeowners invest in a professional roof treatment every year or so to keep things under control and avoid bigger repair bills.
In Wellington, roofs don’t usually grow as much moss, but they do catch grime, pollution and salty residue thanks to the region’s coastal winds. A professional soft wash is usually better than aggressive water blasting, which can damage protective coatings. Many local property owners book roof cleaning in Wellington every 18–24 months to prevent build-up.
Gutter Cleaning: Often Forgotten, Always Needed
Blocked gutters can cause huge headaches if left too long. In Otago, moss, pine needles and autumn leaves quickly fill gutters, leading to blockages, overflow and damp walls. It’s no surprise that gutter cleaning in Otago is one of the top seasonal maintenance jobs homeowners book each year.
In Wellington, the wind carries debris from nearby trees and rooftops, plus the occasional bird nest, which can clog your guttering just as easily. Many Wellington property managers recommend cleaning gutters twice a year — usually after autumn leaves drop and again before the summer storms hit.
House Washing: Walls Take a Beating
The exterior of your house puts up with a lot. In coastal Wellington suburbs, salt spray from the sea sticks to your cladding, window sills and decks. If it’s left too long, that salty film can eat away at paint and metal fixings. This is why professional house washing in Wellington is a smart investment every year — or even twice a year for homes exposed to strong coastal winds.
Meanwhile, in Otago, damp air and shade encourage green slime, mildew and mould to grow on weatherboards and brickwork. A good building wash once a year helps remove mould, freshen up paintwork, and keep your property looking well cared for.
Driveways and Paths: Hidden Slip Hazards
In Otago, you’ll often spot dark green moss and algae spreading across driveways, garden paths and patios. It might look harmless but turns dangerously slippery in wet or frosty weather — a real hazard for families, visitors or tenants. Booking a driveway clean each year is an easy way to reduce slip risks and extend the life of your concrete or pavers.
Wellington homeowners see more general grime than moss on their driveways. Dust, dirt and salt are carried in on coastal winds, leaving stains behind. A gentle water blast or soft wash can lift this grime before it becomes an eyesore.
Windows: A Battle With Salt and Dirt
Windows are another part of the home that show regional differences. If you live anywhere near Wellington’s coastline, you’ll know the pain of salty residue sticking to glass and frames. It never seems to go away on its own, no matter how much rain hits it. Booking regular window cleaning in Wellington not only keeps your views clear but also protects aluminium and timber frames from salt corrosion.
In Otago, windows collect dirt, dust and moss spores, especially around seals and frames. Professional window washing every few months can extend the life of your window joinery — and help you spot leaks before they become bigger problems.
Spiders and Pests: Where They Hide
Homes across both regions are magnets for spiders, but they’re especially active around sheltered eaves, window sills and fences. In Otago’s colder months, pests often move indoors too. This is why many property owners book annual spider treatments to clear cobwebs and keep unwelcome visitors out.
Combining a professional spider treatment with your annual house wash is a great way to tackle exterior pests and keep your home looking neat at the same time.
Interiors: Managing Moisture and Mould
Inside your home, the regional challenges continue. In Otago, cold winters and less ventilation can lead to damp corners, musty wardrobes and hidden mould behind curtains. A good rule of thumb is to clean carpets professionally once a year and check for mould every change of season.
Wellington interiors tend to suffer more from dust and debris blown in by open windows and doors on windy days. Regular vacuuming, air purifiers and seasonal carpet cleaning keep living areas fresh and healthy.
How Often Should You Book Cleaning Services?
How often you tackle each task depends on your local climate and how exposed your home is. Here’s a simple guide comparing typical Otago vs Wellington cleaning schedules:
| Service | Otago | Wellington |
| Roof Treatment | Every 12–18 months | Every 18–24 months |
| Gutter Cleaning | Twice a year | Twice a year |
| House Washing | Annually | Annually or twice a year for coastal |
| Driveway Cleaning | Annually | Annually |
| Spider Treatment | Annually | Annually |
| Carpet Cleaning | Annually | Annually |
| Window Cleaning | Every 3–4 months | Every 3–4 months if coastal |
