5 min8 June 2026Planning & Cost

Before signing any contracting agreement, there are specific questions you should get clear written answers to. This guide gathers the most important ones, often overlooked until a problem shows up later.

Questions about materials and specifications

  • What exactly is the material's source, and can specifications be clarified in writing?
  • Are there alternatives with different specs, and what's the price and quality difference?

Questions about timeline and execution

  • What's the detailed timeline from signing to handover?
  • Who's the supervisor responsible for daily project follow-up?
  • How are unexpected delays handled?

Questions about warranty and responsibility

  • Does the warranty cover materials and installation together, or only one?
  • What's the exact warranty period, and what's excluded from it?
  • Who's responsible if an issue appears after handover?

Questions about changes and extra costs

Ask clearly: is the stated price final and all-inclusive, or could extra costs appear during execution? And if you want a mid-project design change, how is that calculated?
