01Understand what the surface can tolerate
A hard tile responds differently from porous stone, fragile joints or an existing coating. We assess condition and select an appropriate pressure and method. Where needed, a trial area establishes the effect before the work proceeds across the surface.
02Systematic surface cleaning
The work covers the agreed area, such as an entrance zone, path or paved site. We clean systematically, including edges and transitions. Not every discolouration is dirt; ingrained staining and underlying damage may remain visible after the surface is cleaned.
03Water and surroundings matter
Exterior cleaning requires water supply, drainage and protection of adjoining areas. We consider doors, vulnerable planting, traffic and people using the site. Barriers and removal of released dirt are addressed during preparation rather than left until work begins.
04Ready for continued use
We check the treated surface and remove agreed loose residues after cleaning. Joint repairs, impregnation and specialist wastewater treatment require separate assessment. For recurring contamination, periodic care may be more appropriate than repeatedly applying an intensive treatment.
