Blocked gutters are one of the most common — and costly — causes of water damage to Wellington homes. With heavy rainfall, steep terrain, and leafy suburbs, it doesn’t take long for gutters to fill up and overflow, putting your roof, walls, and foundations at risk.
At Metro Water Blasting, we provide professional gutter cleaning services across Wellington, from the hills of Karori and Khandallah to the coastal homes of Lyall Bay, Island Bay, and Seatoun. Whether you need a once-off clean or regular maintenance, our team is equipped to clear the mess, flush your system, and prevent damage before it starts.

Why Gutter Cleaning Is Critical in Wellington
Wellington’s weather and landscape create perfect storm conditions for gutter blockage:
- High rainfall — Over 1,200mm annually, especially heavy in spring and winter
- Bush-lined suburbs — Trees drop leaves, pine needles, and seeds into open gutters
- Strong winds — Blow dust, debris, and roof grit into gutter channels
- Hilly terrain — Leads to fast water flow, runoff, and overflows during storms
When gutters clog, water backs up — damaging soffits, rotting fascia boards, seeping into internal walls, and even flooding basements in suburbs like Brooklyn and Aro Valley.
Suburb-by-Suburb Breakdown
✅ Khandallah & Ngaio
Heavy leaf fall from native bush and established trees. Gutters fill fast in autumn and spring — we recommend biannual cleaning.
✅ Karori & Wilton
Large properties with high roofs and complex downpipes. Frequent moss buildup, especially on tile roofs. Blockages lead to valley flooding and soffit leaks.
✅ Lyall Bay & Island Bay
Sea spray, salt deposits, and wind-driven grime accelerate blockages. Salt-laden moisture also corrodes metal gutters quickly if not kept clear.
✅ Brooklyn & Aro Valley
Shaded, steep sections mean moisture stays longer in gutters. Plant growth is common — we often remove ferns, weeds, and even moss mats.
✅ Mount Victoria, Te Aro & Newtown
Urban grime, bird nests, and roof grit are common here. In-fill housing and flats often have neglected gutters — perfect candidates for a reset.

What Can Happen If You Don’t Clean Your Gutters
Blocked gutters can lead to serious issues:
- Rotting fascia and soffits
- Overflow that stains cladding
- Interior leaks and ceiling damage
- Mould growth inside the home
- Foundation erosion on sloped sites
- Mosquito and rodent breeding grounds
Prevention is cheaper than repairs. Most Wellington homes need gutter cleaning every 6 to 12 months, especially those under trees or exposed to wind.
Before & After: Wellington Gutter Jobs
✅ Karori – A heritage villa had overflowing gutters and black stains on the weatherboards. We cleared a full year of buildup and flushed all downpipes.
✅ Island Bay – A rental property with a metal roof had ferns growing in the gutters. Our team removed plant growth, flushed the system, and prevented future moss regrowth by treating the roof.
✅ Mount Victoria – We cleaned three-storey townhouses using safety harnesses and long-reach equipment, restoring full flow and preventing further overflow into the internal gutters.
