That driveway that used to look nice and tidy is starting to look a bit more green than grey. The deck has picked up a layer of grime, the concrete paths are looking tired, and the outside of the house could probably do with a good clean too.
Sound familiar?
If you're wondering how much water blasting costs in NZ, completed water blasting and pressure washing tasks on Ezy Peazy show that customers have paid between $90 and $380 for the completed jobs reviewed. These included everything from small waterblasting jobs and pathways through to driveways, decks, exterior windows and full house washing.
Where there isn't enough completed Ezy Peazy task data for a particular service, we've also included current NZ market pricing from water blasting and exterior cleaning providers to give you a more useful guide.
A small path or outdoor area may cost around $100–$200, while a standard driveway can be around $180–$350. Larger jobs covering several outdoor surfaces or a full house wash can cost considerably more.
This guide breaks down typical water blasting prices in NZ for driveways, decks, concrete, patios and house washing, along with the factors that can affect your final quote.
Based on the completed Ezy Peazy tasks reviewed and current NZ market pricing, residential water blasting and exterior cleaning can range from around $90 for a small job to $700+ for larger or more complex work.
The $100–$200 small-area range is consistent with both the completed Ezy Peazy pathway job at $120 and current NZ market guides. Current NZ pricing guides put small driveways around $120–$180, medium driveways around $180–$300, and large driveways around $300–$500, although actual prices vary by provider and job.
For house washing, current NZ providers commonly advertise standard homes in the $249–$450 range, while larger or multi-level properties can move considerably higher.
These ranges are useful for budgeting, but they aren't fixed rates or a simple per-square-metre price list. A small driveway covered in years of moss, algae and grime can take more work than a larger area that only needs a quick clean.
For the most accurate price, it's best to get a quote based on your actual property and the work required.
Water blasting uses pressurised water to remove dirt, moss, algae, mould, grime and other surface buildup from outdoor areas.
In everyday NZ usage, water blasting and pressure washing are often used to describe the same type of service. So if you've searched for "pressure washing cost NZ", you're generally looking at the same sort of residential cleaning work.
Water blasting is commonly used for:
It's particularly useful around NZ homes because damp weather, rain and shaded areas can encourage moss and algae growth. A driveway beside a hedge, a south-facing path, a deck under trees or paving near a fence can all become green and slippery over time.
But more pressure isn't always better.
Concrete can generally handle more pressure than timber, painted cladding, windows and other softer or more delicate surfaces. The right pressure, nozzle and cleaning method should be chosen for the surface being cleaned.
For painted surfaces, house cladding and some other exterior materials, a lower-pressure clean or soft-wash method may be more suitable.
A typical residential driveway water blasting job in NZ can cost around $180–$350, while larger driveways, parking areas, or jobs that also include paths, paving, steps, or a carport can reach $500 or more.
There is useful real-world Ezy Peazy pricing here. One completed Ezy Peazy task involved water blasting a driveway for $200. Other completed water blasting jobs on the platform were priced at $120, $250, and $300, showing how much the scope of the work can affect the final price.
Current NZ market pricing broadly supports a range of around $120–$180 for a small driveway, $180–$300 for a medium driveway, and $300–$500 for a larger driveway, before additional treatments or complications.
The final driveway cleaning price can depend on:
If your driveway is starting to look like it belongs in a rainforest, it'll probably take more work than a concrete surface that only needs a quick tidy-up.
A typical deck water blasting job can cost around $180–$400+, depending on the size of the deck, the condition of the timber, and how much cleaning is required.
A completed Ezy Peazy task involving cleaning mould from a deck and concrete area cost $300. Because that task included more than just the deck, it shouldn't be treated as a standard deck-cleaning rate, but it provides a useful real-world example of what a more involved outdoor cleaning job has cost on Ezy Peazy.
Some current NZ market guides put deck cleaning at around $80–$250 for straightforward cleaning, with larger or more involved decks potentially costing more.
Decks need more care than concrete. Excessive pressure can damage timber, leaving the surface rough, splintered or "furred". The pressure setting, nozzle and cleaning technique all matter.
The price may increase when the job includes:
If you're cleaning a deck before staining or oiling it, mention that when requesting a quote. Cleaning, sanding and staining may need to be planned as separate stages.
Concrete water blasting generally costs around $150–$400+, depending on the size of the area, its condition, and how much detailed cleaning is required.
A completed Ezy Peazy task involving mould removal from a deck and concrete area cost $300, while another completed task involving water blasting of a pathway and backyard was $120.
These completed jobs demonstrate how much the price can change depending on the size, condition, and scope of the concrete areas being cleaned.
Current NZ pricing guides also put hard-surface water blasting around $3–$4 per square metre in some markets, although providers may use minimum charges or quote based on the overall job rather than simply applying a per-square-metre rate.
Concrete cleaning can include:
Green algae and moss are particularly common in damp or shaded areas. A path under trees, the side of a house that gets little sun, or concrete near garden beds may need more than a quick rinse.
For tougher stains, a suitable cleaning solution or treatment may be needed before water blasting. This can help with ingrained grime, oil marks, algae and established moss.
Patio and courtyard cleaning typically costs around $150–$350, depending on the size of the area, surface material and how easy it is to access.
There isn't enough completed Ezy Peazy task data in the examples reviewed to give a reliable patio-only price. The $150–$350 range is therefore a current NZ market guide, rather than an Ezy Peazy completed-task average.
A small paved courtyard may be fairly straightforward. A larger outdoor entertaining area with pavers, steps, furniture, garden edges and stubborn moss can take considerably longer.
The price can increase if the job involves:
If your patio, paving and paths all need attention, combining them into one job may be more practical than arranging separate visits.
House washing jobs can cost around $250–$450 for many standard NZ homes, with larger, two-storey or more complex properties potentially reaching $550–$700+.
There is strong completed-task evidence from Ezy Peazy for this category:
These are useful examples of actual completed Ezy Peazy jobs, but they shouldn't be interpreted as a fixed Ezy Peazy house-washing rate because the scope of each property was different.
There's also an important distinction to make: your house doesn't necessarily need high-pressure water blasting everywhere.
Exterior cladding, windows, painted surfaces, soffits, and some roofing materials can require lower-pressure cleaning or soft washing to reduce the risk of damage. The cleaning method should be suited to the surface.
House-washing costs can be influenced by:
Wondering why two people can quote quite different prices for what sounds like the same job?
It's usually down to a handful of practical factors.
A small patio won't take as long as a 150 m² driveway, paths, and backyard concrete area.
Larger jobs generally require more time, water, equipment and labour. Cleaning several nearby areas during the same visit can sometimes make better use of the time and equipment involved.
Light dirt is one thing. Years of moss, algae, mould, oil and grime are another.
A surface that hasn't been cleaned for years may need pre-treatment, multiple passes, or more detailed stain removal. Damp, shaded areas can need additional attention because moss and algae become more established.
Concrete is different from timber. Timber is different from brick. Brick is different from painted cladding.
The cleaning method needs to suit the material. That can affect the equipment, pressure setting, treatment, and time required.
A wide driveway right beside the road is usually fairly straightforward.
A backyard deck down a narrow side passage is a different story. If equipment and hoses need to be moved a long way around the property, or there are stairs, slopes, gates and restricted parking, the job can take longer.
A basic driveway blast may cost less than a more complete exterior clean that includes paths, steps, patios, garage floors, paving and treatment for moss or algae.
When comparing quotes, check the scope. Find out whether setup, pre-treatment, cleaning, rinsing and basic cleanup are included or priced separately.
Water blasting prices can vary between regions and individual providers.
You may see different pricing in Auckland, Christchurch, Wellington, Hamilton and Tauranga because labour costs, demand, property types, travel time and job complexity can differ.
For example, current NZ pricing guides put Auckland water blasting around $150–$400 depending on job size and complexity, while published regional estimates can differ between Auckland, Tauranga, Christchurch and Wellington.
Rather than relying on a national "per square metre" price, getting quotes based on your actual property is usually the most accurate way to understand what you'll pay.
Every provider has a different process, so it's worth confirming exactly what's included before booking.
A standard water blasting job may include:
Some jobs may require additional work or cost more, including:
A lower quote isn't always a better quote if it excludes necessary preparation, treatment or cleanup. Make sure you're comparing like for like.
If you've searched for "pressure washing cost NZ", you may have noticed that results also use the term water blasting.
In most everyday NZ contexts, the terms are used interchangeably. Both refer to using pressurised water to clean exterior surfaces such as driveways, concrete paths, patios and paving.
The more important difference is usually the cleaning method, not the label.
High-pressure cleaning can work well for many hard concrete surfaces, while a lower-pressure or soft-wash approach may be more suitable for cladding, painted surfaces, timber and other delicate materials.
When requesting a quote, describe the surface you want cleaned rather than assuming one method will suit every part of the property.
Water blasting can make a big difference to driveways, concrete paths, patios, decks, and other exterior areas that have become dirty, green, slippery, or weathered.
Whether you need a driveway clean, deck preparation before staining, concrete washing, patio cleaning, or a more complete house-washing job, posting clear photos and details will help you receive more accurate offers.
Post your water blasting task on Ezy Peazy, compare offers from local taskers, and choose the one that suits your budget, timing, and job.
