Start with the cause
Faucets, sinks, toilets, disposals, and appliance hookups should fit the existing pressure, valves, and waste layout. A useful evaluation connects the symptom to pressure, flow, drainage, venting, age, and access.
Questions for the scope
- What is being repaired or replaced?
- How will the area be accessed and protected?
- Are permits or inspections expected?
- How will the completed work be tested?
- Who handles finish restoration?
