## Composite vs Wood Decking: The Complete Comparison

Choosing between composite and wood decking is one of the biggest decisions in an outdoor project. Both materials have clear strengths, and the right choice depends on your budget horizon, willingness to maintain the deck, and aesthetic preferences. This guide compares every factor side by side.

### Head-to-Head Comparison

| Factor | Treated Softwood | Hardwood | Composite |
|--------|-----------------|----------|-----------|
| Material cost per m2 | EUR 15-30 | EUR 40-80 | EUR 25-75 |
| Installed cost per m2 | EUR 80-140 | EUR 130-220 | EUR 120-200 |
| Lifespan | 10-20 years | 25-40 years | 25-30 years |
| Annual maintenance | Oil/stain every year | Oil every 1-2 years | Wash once a year |
| Maintenance cost per year | EUR 30-60 | EUR 30-60 | EUR 5-15 |
| Colour options | Unlimited (stain any colour) | Natural tones only | Wide factory range, fixed |
| Fade resistance | Low without treatment | Moderate | High (capped boards) |
| Slip resistance (wet) | Moderate (grooved) | Low (smooth) | Good (textured surface) |
| Splinter risk | Yes, increases with age | Yes | None |
| Scratch resistance | Low | High | Moderate to high |
| Can be refinished | Yes — sand and re-stain | Yes — sand and re-oil | No — surface cannot be sanded |
| Weight per board | Lighter | Heavier | Heavier than softwood |
| DIY difficulty | Easy | Moderate (hard, dense wood) | Easy |

### Total Cost of Ownership Over 20 Years

This is where the real comparison happens. Upfront cost tells only part of the story.

| Cost Component | Softwood (20 years) | Composite (20 years) |
|---------------|-------------------|---------------------|
| Initial materials (15 m2) | EUR 450-825 | EUR 825-1350 |
| Installation (if professional) | EUR 750-1500 | EUR 750-1500 |
| Annual treatment (oil/stain) | EUR 600-1200 | EUR 0 |
| Annual cleaning | EUR 100-200 | EUR 100-200 |
| Board replacements | EUR 150-300 | EUR 0 |
| Full deck replacement at year 15 | EUR 450-825 | EUR 0 |
| **Total (DIY build)** | **EUR 1750-3350** | **EUR 925-1550** |
| **Total (professional build)** | **EUR 2500-4850** | **EUR 1675-3050** |

Softwood costs more over 20 years because you pay for annual treatment, periodic board replacement, and potentially a full rebuild at year 15. Composite's higher upfront cost is recovered by year 6-8, after which it is consistently cheaper.

### When to Choose Wood Decking

Wood decking is the right choice when:

- **Budget is tight right now** — Softwood costs 40-50% less upfront than composite
- **You enjoy maintenance** — Some homeowners find annual sanding and oiling therapeutic and satisfying
- **You want to change the colour** — Wood can be sanded and re-stained in any colour at any time
- **Authenticity matters** — Real wood has a warmth, grain variation, and natural ageing that composite cannot fully replicate
- **Environmental priority** — FSC-certified timber is renewable, biodegradable, and recyclable

### When to Choose Composite Decking

Composite decking is the right choice when:

- **You want minimal maintenance** — Composite needs only an annual wash, no sanding, oiling, or staining
- **You are building for the long term** — If you plan to keep the deck for 15+ years, composite is cheaper overall
- **Splinter safety matters** — Families with young children benefit from composite's smooth, splinter-free surface
- **Consistent appearance** — Composite maintains its colour and texture year after year without fading or greying
- **You want a warranty** — Most composite manufacturers offer 20-25 year warranties; wood rarely has more than 10 years

### Appearance Over Time

| Year | Softwood (untreated) | Softwood (annually oiled) | Composite |
|------|---------------------|--------------------------|-----------|
| 0 | Golden brown | Golden brown | Factory colour |
| 1 | Greying starts | Maintained colour | Factory colour |
| 3 | Silver-grey, possible green algae | Maintained colour | Slight weathering, even |
| 5 | Fully grey, surface roughening | Maintained, minor wear | Minimal change |
| 10 | Splitting, moss, structural concern | Good if maintained, some board replacement | Consistent, minor patina |
| 15 | Likely needs replacement | Usable but showing age | Still performing well |

### Environmental Impact

| Factor | Softwood | Composite |
|--------|----------|-----------|
| Raw material | Renewable timber (FSC-certified available) | Recycled wood fibre + recycled plastic |
| Manufacturing energy | Low | Moderate to high |
| Transport weight | Lighter | Heavier (higher carbon per unit) |
| Treatment chemicals | Preservatives, stains, oils | None needed |
| End of life | Biodegradable, recyclable | Not recyclable, landfill |
| Carbon storage | Stores carbon throughout lifespan | Locks recycled material out of waste stream |

Neither material is a clear environmental winner. Sustainably sourced and well-maintained softwood is renewable and biodegradable. Composite diverts plastic from landfill but creates a product that itself cannot be recycled. The greenest option depends on your priorities — renewability or waste diversion.

### Making Your Decision: Quick Checklist

**Choose softwood if:**
- Your budget is under EUR 50 per m2 for materials
- You do not mind annual maintenance weekends
- You want to stain or paint the deck a specific colour
- You prefer the look and feel of real wood
- Sustainability and end-of-life recyclability are priorities

**Choose composite if:**
- You want to build once and forget about maintenance
- You are staying in the property for 10+ years
- You have young children (no splinters)
- You value a long manufacturer warranty
- You want consistent colour without annual treatment

## Frequently Asked Questions

### Which lasts longer, composite or wood decking?

Composite decking lasts 25-30 years with minimal maintenance. Treated softwood lasts 10-20 years with annual oiling and occasional board replacement. Hardwood (ipe, cumaru) lasts 25-40 years but is expensive and requires regular oiling to maintain its colour.

### Which is cheaper in the long run, composite or wood?

Composite is cheaper over 15+ years. A 15 m2 softwood deck costs EUR 1250-2325 over 15 years (including annual treatment and repairs), while composite costs EUR 925-1500 over the same period. The higher upfront cost of composite is offset by near-zero maintenance.

### Does composite decking look as natural as wood?

Modern composite decking closely mimics wood grain and comes in a wide range of natural colours. However, it does not develop the natural patina that real wood gets over time. Some people prefer the authenticity of real wood, while others value composite's consistent appearance year after year.

### Can composite decking be stained or painted?

Most manufacturers advise against staining or painting composite decking because the surface is designed to resist absorption. Some specialist composite coatings exist, but they rarely last long. If you want to change the colour of your deck in future, wood is the better choice.

### Is composite decking slippery when wet?

Early composite decking had a reputation for being slippery, but modern capped composite boards have textured surfaces with good grip. Most quality composite boards meet or exceed the slip-resistance ratings of smooth-planed timber. Always check the manufacturer's slip-test ratings.

### Is composite decking environmentally friendly?

Composite decking is typically made from recycled wood fibres and recycled plastic, which diverts waste from landfill. However, composite boards themselves are not recyclable at end of life. Sustainably sourced FSC-certified timber is renewable and recyclable, making the environmental comparison nuanced.
