A total is not a scope
A remodel proposal should explain the work behind the price. It should identify rooms, demolition, protection, preparation, materials, installation, trade responsibilities, cleanup, exclusions, allowances, and known assumptions.
Clear documentation is especially important when several specialized trades contribute to one result.
Changes are normal; undocumented changes are the problem
Owners make new decisions and concealed conditions can appear after demolition. The change process should explain what changed, why, the added or reduced price, the schedule effect, and whether another selection or approval is needed.
The safest rule is simple: document and approve the change before the changed work proceeds, except where immediate action is required to protect life or property.
Questions to ask before signing
Ask who is responsible for permits, design, material ordering, delivery, protection, debris, utilities, inspections, punch work, and final documentation. Ask how allowances are reconciled and how owner-supplied materials affect schedule and warranty responsibility.
