Diagnosis and access
Locating the affected component, tank accessibility, trenching, existing site plans and inspection requirements can change the work. Ask what the quoted diagnostic fee includes and whether it is credited toward repairs.
Soil and design
If a field or system change is needed, soil conditions, allowable location, system sizing, groundwater and permitted design can materially change the project. Ask how the contractor determined the proposed method.
Equipment, restoration and approvals
Clarify material specifications, excavation access, utility locate responsibility, driveway/landscape repairs, permit fees, inspections and written warranty terms. Missing line items may reappear later as change orders.
Compare total scope, not headline price
Two proposals are not comparable if one excludes backfill, inspection or field restoration. Use the worksheet and ask each contractor to annotate what is included and excluded.
