START WITH THE CONDITION
A useful repair starts with understanding what has actually failed.
Protect bathroom wet areas with a scope matched to the condition and project.
CareSeal reviews the visible condition, likely water path and surrounding joints before defining a scope. The objective is a practical repair—not unnecessary demolition or a one-size-fits-all treatment.
Common signs to look for
✓Recurring wet-area leak
✓Water damage beyond tiled surface
✓Renovation or repair requiring waterproofing work
✓Failed wet-area junctions
✓Moisture below or beside tiled areas
✓Surface repair not appropriate for the condition
WHAT CAN BE BEHIND THE PROBLEM
The visible symptom is only part of the story.
Flexible joints
Transitions, penetrations and changes of plane need careful detailing.
Water path
Existing finishes can hide the location or extent of a failure.
Repair scope
The right scope depends on whether a targeted repair or broader intervention is appropriate.

QUESTIONS BEFORE YOU BOOK
Bathroom Waterproofing FAQs.
How do I know if I need bathroom waterproofing?+
The visible symptom is a useful starting point, but the correct scope depends on the condition of the tiled area, joints and surrounding wet-area details. CareSeal reviews the evidence before recommending work.
How much does bathroom waterproofing cost?+
CareSeal provides a clear quote after reviewing the condition and required scope.
Can CareSeal avoid removing sound tiles?+
Where a suitable surface-first repair can address the identified defect, the aim is to keep sound tiles in place. Some conditions require a broader repair, so this depends on assessment.
How long does the work take?+
Many CareSeal wet-area repairs are completed within 1–2 days, depending on access, area, preparation and the agreed scope.
Is the work guaranteed?+
Qualifying CareSeal work can include a written guarantee of up to 7 years. The applicable guarantee depends on the service and scope quoted for your job.
