Assessment & pre-treatment
Before any washing begins, we carry out a full on-site assessment of the area. This includes checking drainage points and clearing any blocked drains or grates that could cause water pooling or runoff issues during the clean. We also inspect the surface for cracks, loose pavers, or existing damage, and flag anything that could affect the wash or worsen with high-pressure cleaning. Where staining is deeply set — oil marks, moss, algae, and built-up leaf and dirt residue — we apply a pre-treatment to break down grime before washing begins.
