What Affects the Price of an Estimate?

Take-off and cost planning fees depend on the size and complexity of the project, the quality of the drawings supplied, and how quickly you need the result. We confirm a fixed price before any work begins.

  • Project type — single-room renovation, new home, or commercial build
  • Number of drawings, revisions, and trades to be measured
  • Level of detail required — budget range or fully itemised schedule
  • Turnaround time, with same-day options available on request
  • Currency, local rate libraries, and measurement standards used

Payment is taken once you approve the quote, and all deliverables are sent in editable spreadsheet format so you can keep adjusting rates.

Need a Fixed Quote?

Send your drawings or project details and we'll reply with a fixed price and delivery date — usually within one working day.
