Start with the conditions downstairs
Photograph staining, odors, visible cracks and previous repairs. Ask the contractor to identify conditions that must be resolved before finishes are installed rather than burying them behind new walls.
- Record where moisture has appeared.
- Describe previous waterproofing work.
- Keep storage clear for the initial assessment.
Define the use of each space
A recreation room, bedroom and separate apartment are different projects. Ask the local authority and project designer which approvals and room requirements apply to the intended use.
- Mark stairs, windows and access routes.
- Separate finished rooms from utility space.
- Discuss requirements before ordering materials.
Compare the complete basement scope
Look for preparation, partitions, ceilings, floors, doors and finish work. A proposal for an open room will not match one with several enclosed spaces and a bathroom.
- List rooms and approximate dimensions.
- Check whether moisture work is a separate contract.
- Ask what is excluded from the final total.
