Why Include Contingency Materials?

The contingency items are not optional extras - they're insurance against common issues that occur in every DIY project:

  • Dropped fixings: Screws and nails fall into grass, get bent, or rust
  • Cutting mistakes: Timber occasionally needs replacing
  • Damaged materials: Cladding boards can split during transport
  • Unforeseen requirements: Extra bracing or adjustments
