Tiled paving on Were Street, Brighton, cleaned in July 2025. The tile itself was in good order — it was the grout lines between them doing all the damage to how it looked. That is the usual case with tiled outdoor areas. The eye reads the dark grid, not the tile, so a surface that scrubs up fine still looks filthy.


Grout and tile are two different materials in the same surface, and they do not clean the same way. Grout is softer, far more porous, and sits slightly lower, so everything washed off the tile ends up in the joints. Clean only the tile and the grid stays dark, so the area looks barely touched.
Pressure had to be managed at the joints rather than at the tile. Grout blows out under a close, square hit, and the repair costs more than the clean did. Passes were worked across the joints instead of running along them, which spreads the force rather than driving it into one line. The area was checked for sealer first: stripping a failing sealer unevenly leaves a blotchy finish worse than the dirt.
