Before the visit
Document the leak pattern and avoid applying sealant over wet or failing finishes. Coordinate access with building management for shared or inter-floor issues.

Questions & booking
Before we visit.
Is every leak a waterproofing problem?
No. Leaks can come from plumbing, sealant, grout, aircon drainage or external sources.
What photos help?
Send wet areas, joints, grout lines, windows and nearby fixtures.
Can old silicone be replaced?
Often yes, if the surface is suitable and the issue is sealant-related.
Is there a warranty for waterproofing work?
Ask about the terms for the specific proposed work before you accept a quote. Coverage can depend on the treatment, substrate, source of the leak and agreed exclusions.
