Deck cleaning costs typically start at $3 per square metre for painted, standard timber, and composite decks. Non-painted or bare timber decks cost more, around $4.50 per square metre, due to the extra care required.
The price depends on your deck’s size, material, and condition. Larger, heavily soiled, or hard-to-reach decks may incur additional charges.
In this guide, we’ll break down the factors that affect deck cleaning costs and what’s included in a professional service.
Deck Cleaning Cost Breakdown
Deck cleaning costs in New Zealand are calculated based on the size of your deck and the type of material.
Here’s a breakdown of the typical pricing:
| Deck Size (sqm) | Painted/Standard Decks (Cost) | Non-Painted/Bare Timber Decks (+50%) |
|---|---|---|
| 10 sqm | $30 | $45 |
| 20 sqm | $60 | $90 |
| 30 sqm | $90 | $135 |
| 40 sqm | $120 | $180 |
| 60 sqm | $180 | $270 |
| 80 sqm | $240 | $360 |
| 100 sqm | $300 | $450 |
- Standard Rate: For painted decks, timber decks, and composite decking, the cost is $3 per sqm.
- Non-Painted/Bare Timber Decks: These require extra care and are charged at $4.50 per sqm due to the extra time and effort needed.
What Affects Deck Cleaning Cost?
Several factors impact the cost of deck cleaning. Here’s a breakdown of the key elements that influence the price:
1. Deck Size
Larger decks require more time, materials, and cleaning solution. The bigger the deck, the higher the cost due to increased labour and surface area.
2. Deck Condition
Decks that are heavily soiled with moss, algae, grease, or old stains require extra treatment. Cleaning these decks involves more work and potentially additional products (like degreasers or moss removal), which increases the cost.
3. Deck Material
- Painted timber, composite, and standard decks are easier and quicker to clean, thus cost less.
- Non-painted/bare timber decks require special care to prevent damage. The cleaning process needs lower pressure, longer time, and more attention, resulting in a higher price.
4. Accessibility
Decks with difficult access, like raised decks, narrow spaces, or multi-level decks, may require more equipment and labour to clean. This can add to the overall cost due to the extra time and effort needed to reach all areas.
What’s Included in Professional Deck Cleaning?
A professional deck cleaning service includes several key steps to ensure your deck is thoroughly cleaned and maintained. Here’s what to expect:
1. Surface-Safe Washing
The cleaning process begins with the application of water, either through pressure washing or soft washing, depending on the deck material. This ensures the surface is cleaned safely without causing damage.
2. Moss & Mould Removal
Moss and mould are common issues for outdoor decks. Professionals use effective methods to remove these growths, preventing long-term damage and keeping your deck safe for use.
3. Eco-Friendly Detergents
Only eco-friendly detergents are used, ensuring the safety of your deck, the environment, and surrounding plants while effectively cleaning the surface.
4. Careful Pressure Control
Pressure settings are adjusted based on the material of your deck to avoid damage. For example, bare timber decks require lower pressure to prevent splintering or surface damage.
5. Rinse & Final Inspection
After cleaning, the deck is thoroughly rinsed to remove all cleaning solutions, and a final inspection is conducted to ensure the deck has been cleaned to your satisfaction.
Why Regular Deck Cleaning is Important
Regular deck cleaning is essential to maintain both the appearance and longevity of your deck. Here’s why it should be part of your home maintenance routine:
1. Preserve the Deck’s Condition
Dirt, algae, moss, and grime can degrade the surface of your deck over time, causing it to weaken or discolor. Regular cleaning prevents this buildup and extends the life of your deck, saving you money on repairs or replacements.
2. Enhance Curb Appeal
A well-maintained deck adds to the overall attractiveness of your home. Whether you’re hosting guests or considering selling, a clean deck creates a positive impression and boosts curb appeal.
3. Improve Safety
Moss, algae, and dirt buildup can make your deck slippery, increasing the risk of falls and accidents. Regular cleaning removes these hazards, ensuring a safer environment for you and your family.
4. Prevent Long-Term Damage
Left untreated, moss and mould can lead to wood decay, warping, or staining. Regular cleaning removes these growths before they can do permanent damage to your deck’s surface.
5. Maintain Health and Hygiene
Moss and mould not only damage your deck but can also cause health issues, such as respiratory problems. Cleaning your deck removes these allergens and keeps your outdoor space cleaner and healthier.
How Often Should You Clean Your Deck?
The frequency of deck cleaning depends on a few key factors, including usage, location, and environmental conditions. Here’s a guideline to help you determine how often you should clean your deck:
1. General Recommendation: Once a Year
For most decks, annual cleaning is sufficient. This helps maintain the deck’s appearance and prevents the buildup of dirt, moss, and algae.
Cleaning in the spring or after the winter months is ideal, as it helps remove debris and prepare the deck for outdoor use.
2. High-Traffic Decks: Twice a Year
If your deck is frequently used, such as for outdoor dining or social gatherings, you may want to clean it twice a year. Regular use can cause dirt and grime to accumulate faster, requiring more frequent cleaning to keep it looking pristine.
3. After Storms or Severe Weather
Heavy rains, storms, or strong winds can carry debris onto your deck, which may require more frequent cleaning. If your area experiences harsh weather, consider cleaning your deck after each storm to prevent dirt and stains from settling.
4. Decks with Organic Growth (Moss, Algae)
If you notice the growth of moss or algae, you may need to clean your deck more often. These substances can damage the wood or decking material if left unchecked, so clean them off as soon as they appear to prevent long-term damage.
