Define the decision-maker and affected property
Identify whether the line is a common element, limited common element or unit responsibility under the association’s documents. Legal interpretation belongs to association counsel—not the contractor.
Build an inspection record
Use labeled footage, stack or unit references, distances, pipe material, visible conditions and access locations. Store the files where future boards and managers can retrieve them.
Separate immediate cleaning from capital repair
Restoring flow may be urgent. Structural rehabilitation may require bids, engineering input, reserves or phased approvals. Treat these as related but distinct decisions.
Require comparable proposals
Ask bidders to state included lengths, diameters, preparation, access, shutdowns, reinstatements, permits, exclusions, verification and warranty conditions.
Plan resident and vendor logistics
Define notice periods, unit entry, parking/loading, protection paths, elevator reservations, water-use restrictions and emergency contacts.
Create a contingency for changed conditions
Cleaning may expose damage that was hidden. The contract should explain who can authorize additional work and how pricing and schedule changes are documented.
