Driveway & Path Cleaning in Khandallah
Driveway cleaning in Khandallah, coloured-press concrete specialists.
Khandallah driveways are a specialty job. The suburb is full of long, north-facing coloured-press concrete driveways, the patterned, integral-colour finishes popular through the 1990s and 2000s. They’re attractive, durable, and catastrophically easy to ruin with standard water blasting.
Coloured-press concrete has its colour integrated into the surface layer of the slab, usually 2–4 mm deep. Standard high-pressure blasting at 2,500+ PSI strips the colour layer off and exposes the bare aggregate underneath. The “fix” is replacement, not cleaning. James sees two or three Khandallah jobs a year that have already been ruined by less-careful contractors.
The right Khandallah driveway clean uses:
- Lower pressure, 1,500–2,000 PSI, sometimes less
- Colour-safe detergent that lifts moss, oil and tyre marks without abrasion
- Pre-treatment for moss in the patterning grooves
- Controlled rotary cleaner rather than the wand direct
- Optional residual moss treatment to slow regrowth on shaded sections
Typical Khandallah driveway job
- Time: 2–3 hours for a standard suburban driveway
- Surfaces: Coloured-press concrete (most common), exposed aggregate, plain concrete
- Cycle: Every 12–14 months for shaded driveways; 18 months for sun-exposed
- Documented work: Ampur Drive coloured-press driveway
If a contractor quotes Khandallah coloured-press concrete at the same pressure as a regular driveway, they don’t know the difference. Ask before booking.

FAQ
Driveway & Path Cleaning in Khandallah, common questions
-
What's the difference between concrete and paver cleaning?
Same method, different chemistry. Concrete and aggregate go straight to high pressure. Pavers James uses a slightly lower pressure on to avoid lifting the joint sand, and pre-treats the moss in the joints with chemistry so it lifts off cleanly.
-
Will it damage coloured concrete?
Not if James uses the right approach. Coloured-press concrete needs a controlled pressure and a colour-safe detergent, too much pressure exposes the aggregate underneath and ruins the colour. He adjusts the technique on the day.
-
How often should I clean my driveway?
Most Wellington driveways look good for 12–18 months after a proper clean. Shaded driveways and south-facing properties closer to 12; sun-exposed driveways closer to 18+.
-
Do you clean coloured-press concrete safely?
Yes. Coloured concrete is sensitive, too much pressure strips the colour and exposes aggregate. We use a controlled pressure and a colour-safe detergent that lifts moss, oil and tyre marks without damaging the surface treatment.
-
How often does Khandallah need a house wash?
Khandallah's north-facing aspect means less moss than southern suburbs, but coastal salt deposits and dust still build up. Most homes here look best with a wash every 14–18 months. Hillside properties exposed to wind go closer to 12 months.
