Winter in Christchurch can be tough on your home. From moss creeping across your roof to grime building up on driveways and decks, the cold, wet months leave behind more than just puddles. As spring approaches, now is the ideal time to restore your property with a full exterior clean.

Whether you live in the shaded streets of Cashmere or the coastal air of Redcliffs, this post-winter cleaning checklist will help prepare your home for warmer days — and prevent long-term damage caused by moisture, mould, and debris.


Why Post-Winter Cleaning Matters

Cold, damp conditions across winter promote:

  • Moss and lichen growth on roofs and decks
  • Blocked gutters overflowing with leaves and grit
  • Mould staining on house exteriors
  • Slippery concrete and pavers
  • Timber deterioration on fences and decks

Ignoring these issues can lead to:

  • Early paint failure
  • Roof leaks
  • Rotting timber
  • Increased slip hazards
  • Reduced property value

A thorough spring clean isn’t just cosmetic — it’s preventative maintenance that protects your investment.


✅ 1. Roof Cleaning & Moss Treatment

Christchurch roofs take a beating during winter. Moss, lichen, and algae thrive on damp, shaded surfaces.

We recommend a soft wash roof clean followed by a moss treatment, especially in suburbs like:

  • Cashmere, Merivale, St Albans (older homes, shaded roofs)
  • Sumner, Redcliffs (salt exposure, coastal conditions)

✅ 2. Gutter Clearing

Winter storms drop leaves, grit, and debris into your gutters. If left blocked, gutters can overflow — damaging fascia boards, causing leaks, and feeding mould growth.

Now’s the time to:

  • Clear leaves and debris
  • Flush downpipes
  • Inspect brackets and joins

Perfect for properties in Fendalton, Ilam, and Riccarton, where trees are abundant.

✅ 3. House Washing

Rain, wind, and low sun angles create the perfect storm for mould and grime to cling to your home’s exterior.

Our soft wash house washing removes:

  • Mould and mildew
  • Cobwebs and dust
  • Bird droppings and algae

It’s gentle on painted surfaces and ideal for homes in Wigram, Halswell, and Hornby, where road dust and rain splash up from driveways.

✅ 4. Deck & Fence Cleaning

Timber decks and fences become waterlogged and slippery over winter, especially in shaded zones.

A low-pressure timber wash:

  • Removes black mould and green algae
  • Prevents timber rot
  • Extends the life of your oil or stain

We recommend this in suburbs like Huntsbury, Hillmorton, and Addington, where decks are often shaded and moisture lingers.

✅ 5. Concrete & Driveway Cleaning

Cold, wet months leave driveways, paths, and patios slippery and stained.

Our high-pressure concrete cleaning removes:

  • Moss and lichen
  • Tyre marks and grime
  • Safety hazards for families and guests

Especially recommended for St Martins, Spreydon, and Shirley, where driveways and paths are often under trees or shaded fences.
