Deck Cleaning – Get Your Deck Safe and Clean, Fast

A slippery, mould-covered, or heavily stained deck isn't just unsightly — it's a genuine safety risk. Slick algae and built-up grime on decking boards can cause serious slips and falls, especially in wet weather or low light, and the problem only gets worse the longer it's left untreated. If your deck feels unsafe to walk on, or you're noticing dark patches, green film, or a musty smell, this needs attention now, not "someday."

Common Deck Problems Homeowners Face

  • Slippery, slick surfaces caused by algae, moss, or mildew build-up

  • Black or green staining from mould and organic growth trapped in the wood grain

  • Grey, weathered timber that has lost its protective finish and is starting to degrade

  • Grime and dirt build-up in gaps, joints, and along board edges

  • Rust or oxidation stains from outdoor furniture, fixtures, or metal fittings

  • Standing water and poor drainage, which accelerates rot and mould regrowth

  • Loose, splintering, or soft boards that may indicate underlying timber damage

  • Deck lighting or nearby power points affected by moisture, grime, or corrosion

If any of these apply to your deck, don't wait for it to get worse — arrange help today.

Safety Notice — Please Read

Do not attempt to pressure wash, hose down, or clean a deck near power points, outdoor lighting, switches, or any electrical fittings yourself. Water and electricity are a dangerous combination, and mixing the two can result in electric shock or fire. If your deck has any electrical fixtures on or near it — lighting, powerpoints, spa or hot tub connections, or wiring of any kind — this work must only be carried out or assessed by a licensed professional.

Additional safety points:

  • If boards feel soft, spongy, or visibly rotten, avoid walking on the affected area and arrange an inspection before use.

  • Wet, mould-covered decking is extremely slippery. Keep children, pets, and elderly household members away from the affected area until it has been treated.

  • Do not use undiluted chemical cleaners or attempt DIY pressure washing on treated or sealed timber, as incorrect products or pressure can strip finishes and cause further damage.

  • If you smell gas, notice sparking, or see exposed wiring anywhere near the deck, stop immediately and treat it as an emergency.

When in doubt, don't risk it — let YWS arrange a professional to assess it safely.

Frequently Asked Questions

1. My deck is slippery and I have kids or elderly parents at home — how urgent is this?

Very. A slippery deck is a serious slip-and-fall risk. Restrict access to the area and enquire with YWS as soon as possible so a professional can attend and assess it.

2. Is it safe to clean my deck myself with a hose or pressure washer?

Not if there are power points, lighting, or any electrical fittings on or near the deck, and not if the timber is showing signs of rot or damage. In these cases, DIY cleaning can create a serious safety risk. It's safer to arrange a professional through YWS.

3. How do I know if my deck's mould or staining is just cosmetic or a bigger problem?

Black staining, soft spots, or a musty smell can point to deeper moisture damage, not just surface dirt. A professional can assess this properly — don't assume it's only cosmetic.

4. What if I have deck lighting or an outdoor powerpoint I'm worried about?

Do not touch, clean around, or attempt to inspect it yourself. This is an electrical safety matter and should only be handled by a licensed professional. Flag this clearly when you enquire so YWS can prioritise the right support.

5. How quickly can YWS arrange someone to help?

YWS aims to connect you with a suitable professional as quickly as possible, with urgent and safety-related enquiries prioritised. Response times can vary by location and availability.

6. What information should I have ready when I enquire?

It helps to know roughly how large the affected area is, whether there's any electrical fixture involved, whether any boards feel unstable, and how urgent the situation feels to you. If you're unsure, just enquire — YWS will ask the right questions.
