Can a dry visit still consider earlier wetting?
Share dated observations and photographs. Accessible findings should retain any uncertainty about conditions which are not present during the appointment.
Should I create steam to demonstrate the pattern?
Describe normal-use observations instead. Do not deliberately recreate unusual conditions or a suspected damaging water problem for the enquiry.
Does morning moisture prove condensation is the only issue?
Do not assume one explanation accounts for every mark. Keep separate wall or water observations available for appropriate investigation.
Why keep photographs from different times?
They can explain how the same position changes during ordinary use. Dates and locations make them useful rather than contradictory images.
Can one visit exclude every intermittent leak?
No such conclusion should be assumed. Confirm accessible findings and which source questions need another check or arrangement.
What should be compared after treatment?
Return to the original affected positions during normal use, with instructions and any separate work details retained.
