Document what you observe
Where does moisture appear, and when? Name the affected room or outdoor area. Overview photos, connection details, plans and previous-work information help identify further checks.
Consider the build-up
The substrate, edges, penetrations and existing layers may affect planning. Discuss which parts are accessible and which checks are needed before agreeing the work.
Explain the installation
The quote should identify the surfaces and details to be treated and any assumptions. Keep concealed and inaccessible parts visible as points requiring clarification.
