Mould and algae exist because of continued moisture, especially in shaded areas. Concrete and tiles absorb moisture, and the predictable result is black or green mould, or Lichen.  These can become a slip hazard, as well as looking unsightly, and reduce the natural life of the product. Our professional mould removal techniques are able to remove this, and once these products are sealed, they no longer absorb moisture, and the result is a product that keeps its natural look, is safe to walk on, and lasts a lifetime, Yes it will still require cleaning, but only to remove the normal dust, dirt, bird dropping etc, the difference is that the dirt will only sit on top, rather than seeping into the product, and all that is required is quick a rinse of, rather than an intense high pressure clean. We are able to remove Mould From Ceiling  bathroom areas, fixing rising damp problems.
