What To Check
Request labour, materials, access costs, and disposal as separate line items where possible.
Use the midpoint as a planning number, then compare at least 3 written quotes for the same scope.
Expect your final price to move if access is difficult, urgency changes, or the provider uncovers extra remedial work on site.
