How do you pay the building contractors -as per the stages of work?

Paying building contractors by stages typically involves a schedule of payments tied to the completion of specific milestones in the project. This can include initial deposits, progress payments at defined intervals or upon the completion of certain phases (e.g., foundation, framing, roofing), and a final payment upon project completion and inspection. It's important to have clear terms outlined in the contract to ensure both parties understand when payments are due and what constitutes the completion of each stage. Additionally, retaining a small percentage of the total fee until final approval can help ensure quality and satisfaction with the completed work.
