Signs That You Need Exterior Cleaning
A building’s external cleaning is most effective when carried out before surface deterioration becomes permanent. Visual changes to a building’s exterior often indicate that contaminants are starting to affect both appearance and material performance.
Common signs include:
- Visible staining or discolouration
- algae, moss, or mould growth
- dark patches caused by pollution or traffic residue
- streaking beneath windows or gutters
- weathered or uneven surface appearance
Addressing these issues early helps prevent deeper material damage and reduces the need for more invasive restoration work.
What Surfaces Can We Clean?
Exterior building cleaning can be applied to a wide range of materials when the correct techniques are used. Cleaning is adapted to suit each surface to ensure contaminants are removed while preserving the structure and finish.
Surfaces commonly cleaned include:
- brickwork and stone
- render and masonry
- metal and composite cladding
- architectural features and external detailing
Typical contaminants removed include dirt, carbon staining, algae, organic growth, efflorescence, oxidation, bird fouling, and general environmental build-up.
