Paving vs Decking Cost Comparison: Which Outdoor Surface Costs Less Over Time?
Compare paving and decking costs, including installation, drainage, maintenance, repairs, and resale presentation for patios, courtyards, and alfresco areas.
Paving and decking are often quoted as if they are interchangeable square-metre products. They are not. One is ground-based and drainage-sensitive. The other is structure-based and maintenance-sensitive. The better-value option depends on slope, drainage, height, finish expectations and how much maintenance you are willing to carry over the next decade.
Upfront Cost Comparison
| Surface | Low | Average | High |
|---|---|---|---|
| Concrete pavers | $80/m² | $120/m² | $180/m² |
| Premium paving/natural stone | $140/m² | $220/m² | $350+/m² |
| Treated pine deck | $180/m² | $250/m² | $350/m² |
| Composite deck | $220/m² | $320/m² | $450+/m² |
Paving is usually cheaper on level ground with straightforward access. Decking gets more competitive when the site is sloped, elevated, or needs to bridge over services and uneven levels. Paving generally wins for courtyards, patios at grade, pathways and areas that want a hard, low-profile finish. Decking shines on sloping sites, around pool zones, and where the outdoor floor level needs to align with interior floors.
The Cost Factors Owners Miss
- Excavation, spoil removal and drainage below paving
- Sub-base thickness and edge restraints
- Structural framing, stump depth and balustrades for decks
- Oiling, staining or board replacement over time
- Movement, weeds or settlement in paved areas if prep is poor
Paving usually costs less to maintain, but only if drainage and base preparation are done properly. Cheap paving jobs move, pond or weed up. Timber decking often needs washing, oiling or staining every 12 to 24 months depending on exposure. Composite reduces that maintenance but costs more to install.
Frequently Asked Questions
Is paving cheaper than decking?
Usually yes on simple flat sites. Not always on sloping or elevated sites where structural excavation becomes expensive.
Does decking always need more maintenance?
Timber decking usually does. Composite reduces maintenance but lifts the upfront price.
What lasts longer?
Well-installed paving can last decades. Deck life depends more on framing quality, exposure and maintenance discipline.
Which is better around pools?
Both can work. The right choice depends on slip resistance, heat underfoot, drainage and overall site design.
How We Collect These Prices
WhatCosts compares paving and decking costs as full installed systems, not headline material rates. We include prep, access, structural needs and maintenance because outdoor-surface value is mostly determined by the work underneath and the upkeep after handover.
