FAQs
Water Stain On Ceiling FAQs
What causes a water stain on a ceiling?
Common causes include bathroom leaks, concealed pipework, shower or bath leaks, heating pipework leaks and water tracking through floor structures.
Should I repaint the ceiling first?
No. The source should be investigated first, otherwise staining may return and damage may continue.
Can bathroom leaks damage ceilings below?
Yes. Shower, bath, basin or concealed bathroom pipe leaks can cause staining and damage to ceilings below.
Can you provide evidence for insurance?
Yes. Written findings and photographic evidence can be provided for escape of water or trace and access requirements.
Will the ceiling need to be opened?
Not immediately in every case. Non-destructive investigation helps decide whether access is needed and where it should be targeted.
