Start with the finding that changes the decision
Your decision: Compare what each option repairs, what it leaves in place and the evidence supporting that choice. Price comes after the scope is clear.
Ask what has failed and how it was established. A local cap defect, loss of backfill and movement of the wall system raise different questions. The assessment should identify both the damage and the limits of the investigation.
A standard visible inspection does not predict remaining life. If a proposal relies on a claim that the wall has “another twenty years,” ask who made that evaluation and what work supports it.
Compare like-for-like alternatives
| Decision | Repair proposal | Replacement proposal |
|---|---|---|
Structure retained | Which panels, cap and anchors stay? | What is removed or left buried? |
Design basis | Why can the remaining structure support the repair? | Which site measurements and ground information support the design? |
Related work | Are joints, drains and lost soil included? | Are docks, utilities, grading and restoration included? |
Completion | How is the repaired condition recorded? | Who provides inspection records and the final survey? |
A change in scope can change the approvals
For a Naples City parcel, bring the existing cap elevations and adjoining-wall information into the discussion. For a natural waterway, ask City staff about the riprap requirement before comparing a bare-wall bid with a complete shoreline scope.
Gulf-front armoring needs a separate coastal review. An inland-canal price is a poor substitute for a proposal that addresses beach access, coastal approvals and site restoration.

Three different findings, three different conversations
A localized cap defect
Ask whether the investigation supports keeping the panels and anchors. Request a defined repair area and a description of the connection to sound material. A cosmetic finish alone does not answer what the assessment found.
Sinking ground behind the wall
Ask how the soil is leaving and how that path will be addressed. Compare void filling, joint work and drainage as separate items. Filling a depression without explaining the cause leaves the scope difficult to judge.
Movement across several sections
Ask what additional investigation or design is needed before pricing alternatives. Record which parts were examined, which remain concealed, and how each proposal handles the retained wall and neighboring connections.
These examples organize questions; they do not diagnose your property. A visible inspection may leave underwater components and concealed anchors outside its scope. Make those gaps explicit before treating either alternative as complete.
Compare the second project, too
A smaller repair can be a sensible choice only when you understand what it leaves for later. Ask the proposer to mark the components that remain original and identify the next condition review. Avoid assigning a promised lifespan to work that has not been evaluated for that purpose.
For each option, record the initial scope, access needed again, items excluded and documents you will receive. If one quote removes a dock and restores the yard while another excludes both, compare those differences before comparing totals. Keep any future work as an open question rather than an invented allowance.
Write down why you chose the scope
Keep the assessment, alternatives and final exclusions together. Record who will design the work, obtain permissions, protect the site and close the permits. A lower first price can omit work you will still need to buy.
Read the repair scope guide and replacement checklist, then compare the full budget.
