Wellington’s weather — with its wind, rain, salt air, and rugged terrain — doesn’t go easy on exterior surfaces. From moss-covered driveways in Karori to algae-stained concrete in Lyall Bay, outdoor areas across the region build up grime fast.
That’s where professional water blasting services in Wellington come in.
At Metro Water Blasting, we use high-powered, surface-safe techniques to remove years of built-up dirt, mould, algae, and lichen from all types of exterior surfaces. Whether you’re a homeowner in Newtown, a business in Te Aro, or managing rentals in Johnsonville, we have the experience and equipment to get your property looking its best.

Why Wellington Properties Need Water Blasting
Wellington’s terrain and climate accelerate exterior wear:
- Steep hillsides lead to water runoff and erosion
- Salt air (especially in coastal suburbs) promotes lichen and corrosion
- Dense vegetation creates shade, encouraging moss and algae
- Air pollution and traffic grime collect on paths and walls in urban zones
Even new concrete surfaces in areas like Mount Cook, Tawa, or Hataitai can become stained and slippery within a single season.
Water blasting is a fast, effective way to clean:
- Driveways
- Paths and walkways
- Concrete walls
- Retaining walls
- Courtyards and patios
- Carparks
- Fences, decks, and building exteriors (where suitable)
Residential Water Blasting: Make Your Property Shine
If you’re a homeowner in Karori, Khandallah, Wilton, or Brooklyn, you’ve likely noticed moss growing on your driveway or slippery footpaths developing in winter. We use rotary surface cleaners and controlled pressure to restore:
- Driveways (concrete, pavers, asphalt)
- Front steps and paths
- Courtyard areas
- Retaining walls and fences
Our method is especially effective in shaded suburbs like Aro Valley and Ngaio, where concrete and timber retain moisture and grow biofilm.
Commercial Water Blasting in Wellington
We also offer commercial and industrial water blasting services for:
- Office complexes
- Strata & body corporate buildings
- Apartment walkways
- Carparks
- Shops and commercial entryways
- Warehouses and loading bays
Areas like Te Aro, Newtown, and Mount Cook benefit from regular water blasting due to heavy foot traffic, air pollution, and nearby construction. We offer after-hours or weekend scheduling to minimise disruption to your operations.

Suburb-by-Suburb: What We See Most
✅ Karori
Older homes and long, steep driveways collect grime and moss fast. Water blasting safely restores grip and curb appeal.
✅ Lyall Bay
Salt spray and wind-driven sand wear down hard surfaces. Great candidate for patio and retaining wall cleaning.
✅ Newtown
Urban density + old concrete = black algae and biofilm on walkways, fences, and paths.
✅ Brooklyn
Shaded stairways and multi-level paths are common. Water blasting is essential for safety and presentation.
✅ Johnsonville
Newer subdivisions with large exposed aggregate or standard concrete driveways — mossy patches build up quickly.
What Surfaces Can Be Water Blasted?
We can safely blast:
- Concrete – driveways, paths, slabs
- Pavers – clay, concrete, or stone
- Decking – only where appropriate (or consider Deck Cleaning)
- Fencing – concrete or timber
- Exterior walls – brick, concrete, or blockwork
- Courtyards and pool surrounds
- Carparks and loading zones
We do not water blast delicate cladding or painted weatherboards — those are handled with soft washing techniques. We’ll always assess the material before choosing the right method.
Before & After Results
In Hataitai, a rental property had a stained driveway with heavy moss buildup. After water blasting, it was visibly safer, brighter, and more attractive for tenants.
In Mount Victoria, we cleaned an inner-city apartment complex’s entryway and pathways. The black grime and algae were completely removed, restoring the original colour and grip.

Our Process
- Site assessment – We inspect the surface type, grime level, and runoff safety

- Rotary surface cleaning – Even pressure for flat surfaces (driveways, paths)
- Manual edge and vertical cleaning – For fences, steps, and detail areas

FAQs About Water Blasting in Wellington
Q: Will water blasting damage my concrete?
No. We use rotary cleaners and pressure levels suited to your surface type. For fragile areas, we’ll use soft wash alternatives.
Q: Do I need to be home?
Not necessarily. As long as we have access and water, we can complete the job and leave everything tidy.
Q: Can I book recurring water blasting for commercial use?
Yes — we offer monthly, quarterly, or annual commercial plans for shops, buildings, or body corporates.
Q: Do you use hot water?
We use cold water systems, as they are effective for most surfaces. For oil-stained commercial areas, we use degreasers and surfactants.
