Who this guide helps
Households reviewing renovation budgets
The short answer
Separate fixed-scope prices from provisional allowances and owner-selected items. A low estimate can depend on assumptions that have not been checked.
Practical workflow
List each allowance, assumed quantity or quality, exclusions and the process for final pricing. Ask about demolition findings, fixtures, finishing, access and disposal. Link options to the approved design rather than choosing substitutes by price alone.
What a useful handoff looks like
Request scenarios showing how a changed selection or discovered condition is approved and recorded. Confirm taxes, professional charges and permits where applicable. Have technical and contractual questions reviewed appropriately.
Mistakes to avoid
Do not present an allowance as a guaranteed final cost or sign off on a substitute before suitability is checked.
Working example: fields to record
