Wellington winters are wild — gusty southerlies, persistent rain, damp mornings, and salty coastal air. While you’re layering up for the cold, your home is quietly collecting debris, mould, moss, and grime that can lead to costly damage and serious safety risks.

This winter, don’t let blocked gutters or slippery decks sneak up on you. At Metro Water Blasting, we provide full-service exterior winter cleaning in Wellington, helping homeowners prepare their homes for the season and avoid preventable maintenance issues.

Why Winter Is a Critical Time for Exterior Cleaning

Winter isn’t just uncomfortable — it’s the season when outdoor surfaces are under the most pressure:

  • Moss and lichen spread faster due to moisture retention and lack of sunlight.
  • Decks and driveways become slippery, creating serious hazards for kids, pets, and older adults.
  • Gutters clog more easily, especially with storm runoff, pine needles, and general debris.
  • Painted surfaces trap moisture, increasing the risk of rot, mould, and blistering.

If your home is in shaded or elevated suburbs like Brooklyn, Karori, Ngaio, or Wilton, you’re especially vulnerable. These areas rarely dry out between storms, meaning winter grime builds up fast.

Suburbs That Need It Most

While all of Wellington can benefit from winter cleaning, we especially recommend it in these areas:

  • Karori, Northland & Wilton – Bush-heavy suburbs with heavy moss growth and limited sun
  • Brooklyn, Highbury & Kelburn – High wind exposure, cold damp corners, and shaded decks
  • Island Bay, Owhiro Bay & Seatoun – Salt spray, sea mist, and mould on concrete and cladding
  • Johnsonville & Churton Park – Newer builds with large driveways and decks prone to mildew

What to Clean This Winter — and Why

✅ 1. Gutters

Blocked gutters lead to overflowing water, which runs down your exterior walls, pools around foundations, and backs up onto your roof. Winter is the peak time for gutter blockages due to rain + debris.

✅ 2. Decks & Paths

Slippery decks are not just annoying — they’re dangerous. Moss and mould-covered timber becomes hazardous in winter moisture.

We also water blast concrete walkways, tile paths, and patio areas.

✅ 3. Driveways

Slippery or stained driveways can be treacherous in cold weather. We water blast all surfaces — concrete, asphalt, pavers — to remove moss, oil, and mildew.

Before & After: Real Results from Winter Cleaning

In Kelburn, a cedar-clad home had blackened weatherboards on the south-facing wall. Our soft wash removed years of grime in one visit.

A Mount Victoria villa with a wrap-around deck had algae so slick it was unsafe to walk on. We cleaned it, treated it for regrowth, and sealed the timber — all within a day.

Bonus Tip: Treat Your Roof Too

Winter is the worst time to ignore roof moss and lichen. While it’s easy to overlook, buildup leads to water retention, clogged downpipes, and roof decay.
