This was a very satisfying little job as it really cleaned up well and the client was very impressed with the before and after effect in just a couple of hours.
The cleaning process involved removing the mold with professional chemicals and then using specialist acidic and alkali cleaning agents to remove different contamination within the tiles.
I work all over Hertfordshire and North and West London and there are many of these types of tiled pathways in areas such as Tring, Harpenden , Berkhamsted etc
A bit more about this type of work
Believe it or not the cleaning was done in one day then I just needed to return the day after for an hour to seal it. Generally the more green stuff the easier it is to clean as the chemicals I use disintegrate all mold and algae with ease.
This cleaning process can be used on all exterior stone and masonry including Victorian tiles , stone and even bricks.
Cleaning your exterior tiles will leave them less slippery and the sealers we use prevent dirt getting into them as easily for a few years.
