Identify the location
Is the connection inside or outside? Which window and side are affected? A whole-window photo helps identify it. Add close-ups of separated edges, cracks or discolouration.
Name the materials
Include frame, adjoining wall and surface finish if known. Painted areas, natural stone and coated frames may require different approaches. Leave unknown materials clearly marked as unknown.
Record related observations
When is the change noticeable? Is there moisture or a draught nearby? These details help identify checks needed, but do not by themselves prove a cause.
Clarify access
For external connections, reach and access equipment form part of planning. State floor level and access conditions. Further checks depend on the actual window.
