Step by step
7List every option
Put maintain, repair, partial replacement, and full replacement on the list. Keep each until evidence from this unit removes it.
Write down · NoteSurvey this exact unit
Inspect the unit or section in question, after its last change. A survey of another slope or unit does not carry over.
Write down · PhotoSet symptoms aside
Peeling paint, drafts, age, and energy claims are clues about where to look. They do not show the unit is beyond repair.
Write down · NoteName the likely cause first
Write what likely caused the damage and how it will be corrected. A new part can go the same way.
Write down · NoteLook for open water and movement
Note water still entering and possible hidden decay. If anything sags or moves, keep people clear and call an engineer.
Write down · NoteCompare over time
Put repeat repairs, remaining service life, and disruption side by side. Leave prices and product picks to their own step.
Write down · NoteRecord the decision
Write the option chosen, the evidence behind it, and who made the call.
Write down · Decision
A finished run leaves the options considered, the evidence on this unit, the likely cause, and who made the decision.
