Document the surroundings
Include approximate area, existing finish and affected connections. Photos of thresholds, wall junctions and drainage points help explain the request in context. Existing plans are useful too.
Define the work
Is the request about a visible seal, a local repair or investigating waterproofing? These have different scopes. Agree the next steps for the actual property.
Describe access and conditions
Explain how the area can be reached and whether it must remain in use. Scheduling and installation depend on the intended system requirements.
