Scope questions
Ask what is included, what is excluded, who supplies major materials and what assumptions are built into the proposal.
Schedule questions
Ask about expected sequencing, material lead times, access to the home and how schedule changes are communicated.
Change questions
Ask how change orders work and what happens when hidden conditions are discovered after demolition.
Turn the research into a project scope
Online planning is useful up to the point where the answer depends on the actual room, the desired scope and existing conditions. When you are ready to discuss those specifics, call with the project location and the main changes you are considering.
