START WITH THE CONDITION
A useful repair starts with understanding what has actually failed.
Protect suitable kitchen wet areas around tiled floors, splashbacks and water-prone junctions.
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
✓Failed caulk around sinks or splashbacks
✓Water tracking behind a tiled junction
✓Loose or deteriorated grout
✓Moisture around cabinetry edges
✓Cracked flexible joints
✓Repeated dampness after sink use
WHAT CAN BE BEHIND THE PROBLEM
The visible symptom is only part of the story.
Flexible joints
Flexible caulk can shrink, split or lose adhesion over time.
Water path
Damaged grout can hold moisture and make cleaning difficult.
Repair scope
The source may be plumbing-related rather than a tiled-surface defect, so diagnosis matters.

QUESTIONS BEFORE YOU BOOK
Kitchen Waterproofing FAQs.
How do I know if I need kitchen 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 kitchen 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.
