Which decisions make the biggest difference?
For water-damaged material removal, it matters whether the water came from a burst supply line, outside runoff, a sewer/drain backup, groundwater or a sump malfunction. Those sources vary in potential contamination and the work needed after visible water is removed. The materials matter too: a bare concrete slab behaves differently from carpet pad, insulation, finished wood, or a concealed wall cavity.
Age alone is not a reason to throw out every item, and a dry-looking surface is not proof that adjacent materials have reached acceptable conditions. The scope should reflect on-site observations, material limitations and any specialist trade required. Ask why each material is marked for removal, how dust/debris will be managed, and what photographs will be recorded.
