Timber & Composite Care

Deck Cleaning, Auckland-Wide

Gentle, calibrated cleaning that revives greyed, mouldy timber and composite decking — and preps surfaces ready for staining.

Overview

Bring Tired Timber Back to Life

Decks and fences take a constant hammering from sun, rain and foot traffic, leaving timber grey, slippery and prone to mould — and composite decking can dull and stain just as easily without the right care.

We calibrate pressure specifically for timber and composite surfaces, avoiding the gouging and splintering that comes from blasting decking with driveway-level force, and can prep surfaces ready for re-staining or oiling on request.

What’s Included

  • Timber and composite deck cleaning
  • Pergola and handrail wash-down
  • Mould and algae treatment
  • Surface prep for staining or oiling (on request)
  • Gentle pressure calibrated specifically to timber
  • Rinse and clear of light furniture and planters

Auckland Service Guide

Deck Cleaning and Timber-Safe Deck Water Blasting

Deck water blasting must be gentler than driveway cleaning. Hydro Clean calibrates pressure for timber and composite decking to lift algae, mould and weathered grime while reducing the risk of gouging, splintering or opening the timber grain.

If the deck is being prepared for staining or oiling, mention that in the quote request. We can adjust the cleaning approach and advise on suitable drying time before the next coating step.
