Wellington homes face a very different set of exterior challenges compared to other regions in New Zealand. Strong winds, frequent rain, salt-laden coastal air, steep sections, and shaded hillsides all combine to accelerate exterior wear and tear.
In Wellington, exterior cleaning is not cosmetic maintenance — it is protective, seasonal upkeep that prevents moisture damage, corrosion, leaks, and safety hazards. Homes that follow a seasonal maintenance plan consistently last longer, cost less to maintain, and retain higher property value.
This guide explains what Wellington homeowners should clean each season, why timing matters so much in this region, and how professional exterior cleaning protects homes year-round.
Why Seasonal Maintenance Is Essential in Wellington
Wellington’s environment is uniquely harsh on exterior surfaces.
Key regional factors include:
- Strong, persistent winds driving rain into buildings
- Coastal salt exposure across many suburbs
- High rainfall and moisture retention
- Steep terrain increasing runoff pressure
- Shaded hillsides that dry slowly
- Cooler temperatures during winter months
These conditions mean dirt, mould, algae, and salt buildup never fully stop accumulating.
Spring Exterior Maintenance – Recovering From Winter
Spring is the most important maintenance season for Wellington homes. Winter moisture and wind-driven rain often leave behind hidden problems.
Spring risks
- Salt buildup on walls and roofs
- Moss and algae growth
- Debris lodged in gutters
- Slippery paths and steps
- Early corrosion on metal surfaces
Spring priorities
House Washing
Soft washing removes mould, grime, and salt residue that built up during winter.

Moss and debris accumulate quickly on Wellington roofs due to constant moisture and wind.

Summer Exterior Maintenance – Protection and Presentation
Summer brings more outdoor use, but Wellington homes remain exposed to salt air and wind.
Summer risks
- UV breakdown of paint
- Salt residue bonding to surfaces
- Increased foot traffic on outdoor areas
- Wind-blown grime buildup
Summer priorities
Deck Cleaning
Decks in Wellington are prone to algae growth due to shade and moisture.

Winter Exterior Maintenance – Monitoring and Safety
Winter is not ideal for major cleaning but requires close monitoring.
Winter risks
- Wind-driven rain
- Overflowing gutters
- Persistent dampness
- Slippery accessways
Winter focus
- Monitor gutters and downpipes

Why Wellington Homes Require More Frequent Gutter Cleaning

Blocked gutters in Wellington cause:
- Water forced under roofing
- Fascia rot
- Internal leaks
- Wall saturation
Regular cleaning is one of the most important maintenance tasks for Wellington homes.
Coastal vs Hillside Homes in Wellington
Coastal homes
- More salt exposure
- Faster corrosion
- More frequent washing required
Hillside homes
- More shade
- Slower drying
- Faster algae growth
Both benefit from tighter cleaning schedules.
Why DIY Exterior Cleaning Is Risky in Wellington
Wellington’s terrain and wind make DIY cleaning particularly dangerous.
