Terrace construction prices fluctuate 15–30% seasonally due to contractor demand, material availability, and weather risks. Winter offers the deepest discounts while spring/summer carry premiums from high demand and rush jobs. Timing your build correctly can save €500–1,500 on a 20 m² project.

Why Prices Swing Seasonally
1. Contractor Cash Flow Pressure
WINTER PROBLEM: No work = no income
• Crews need winter jobs (heating, mortgages)
• Accept 20-30% lower margins
• "Use it or lose it" equipment overhead
SUMMER PROBLEM: Too many jobs
• Booked 2-3 months ahead
• Rush premiums + overtime
• Selective on "small" projects (<30m²)
2. Material Price Cycles
| Material | Winter Price | Summer Price | Savings |
|---|---|---|---|
| Treated Lumber | –15% (surplus stock) | Normal | 6–9 EUR/m² |
| Composite Decking | –10% (clearance) | +10% (demand) | 8–12 EUR/m² |
| Screws/Fasteners | Stable | Stable | 0 EUR |
| Screw Piles | –20% (off-season) | Normal | 4–6 EUR/m² |
Total material savings: €300–600 on 20m² winter build
Weather Risk Pricing Matrix
| Month | Rain Days (Baltics) | Delay Risk | Contractor Premium |
|---|---|---|---|

| Jul-Aug | 8–12 days | Low | +15–25% (peak) |
| Sep-Nov | 15–22 days | High | +10–20% (rush to finish) |
November Risk: Rain delays = 20% labour overrun
