Record cracked-tile patterns, timing and nearby symptoms before assessment. Avoid assuming a local tile replacement addresses movement or moisture underneath.
A cracked tile is a visible symptom, not a complete explanation. Impact, substrate movement and other installation conditions can require different responses. Before deciding on a local replacement or cosmetic treatment, record the pattern and history for a tiler. This guide prepares the assessment; the existing re-grouting-or-replacement guide addresses the later repair choice once the condition is understood.
Record the pattern without disturbing it
Photograph the whole area and then the individual cracks from safe access. Mark whether the line crosses several tiles, follows a joint or is limited to one piece. Note the room and position relative to a doorway or wall. Do not lift loose tiles, scrape joints or probe underneath to identify the base. Unknown older materials and concealed wet-area components can require appropriate assessment before disturbance.
Describe timing and previous work
Say when the crack was first noticed and whether it followed an impact, renovation, leak or earlier repair. Keep invoices and photographs if available. A crack returning in the same area is useful information, but it does not by itself prove a particular structural fault. If you do not know the history, record that uncertainty. Guessing an installation date or cause can make the assessment less clear.
Report associated symptoms separately
Mention loose-feeling surfaces noticed during normal use, recurring dampness, staining or changes in nearby doors and finishes. Do not deliberately load or tap damaged areas to produce a diagnostic sound. Sharp or unstable pieces should be kept out of normal traffic and assessed promptly. Moisture reaching another room or downstairs needs attention beyond the cosmetic appearance of the tile. Ask which trade should investigate the wider concern.
Ask what the first visit can establish
The tiler may assess the visible installation and recommend further investigation where the base is concealed. The ARDEX bulletin demonstrates why substrate and movement considerations matter for its specific large-format scope, not a diagnosis of your crack. Request a distinction between observed findings and possible causes. Clarify whether any opening-up work requires a separate approval and how adjoining waterproofing or finishes would be protected.
Keep the repair decision evidence-based
Find matching spare tiles and product records if you already have them, but do not order a full replacement before suitability is checked. Ask whether a local repair addresses the identified cause and what limitations remain. Keep the report with the proposed scope. A new tile can improve the surface only within a suitable repair plan; it should not be represented as proof that every concealed movement or moisture issue has been resolved.
