Are tile and silicone treated as the same surface?
Describe each material and condition. Ask which suitable work is needed rather than assuming identical treatment or replacement.
Will a stained seal look new afterwards?
A new finish should not be promised. Discuss suitable cleaning, damage and whether separate replacement is required.
Does a bathroom fan rule out ventilation problems?
Its presence alone does not settle how the arrangement works. Explain observed conditions for the moisture investigation.
Should I scrape the joint before sending photographs?
Leave affected material undisturbed and show accessible details. Discuss preparation instead of scraping or experimenting with products.
Does the quote include plumbing?
Treatment and plumbing repair are distinct tasks. Confirm what was identified and which additional work is separately agreed.
Can I book ordinary bathroom cleaning instead?
Describe mould specifically. General domestic cleaning has a different scope and does not replace moisture assessment or suitable treatment.
