Show condition and area
Photograph the whole surface and individual damaged joints. Mention apparently loose tiles, visible moisture and previous work. Explain whether the area is a bathroom, kitchen or outdoor space.
Consider the existing finish
Assess existing grout, tiles and any visible substrate before work. Agree an installation suited to the property and identify any further checks needed.
Agree the visible result
For partial areas, discuss how the work will look alongside the existing finish. Older colours and different materials may affect the suitable approach.
