Surface Contamination
Exterior surfaces are exposed to the elements, leading to a build-up of dirt, organic growth, and pollutants. We safely remove all types of surface contamination using professional methods.
Common Exterior Contaminants
Different contaminants require different cleaning approaches. At Servos, we use a range of specialist methods, including softwashing, steam cleaning, and controlled pressure systems, to ensure each surface is cleaned safely and thoroughly.
From algae and moss to graffiti and oil stains, we provide tailored exterior cleaning solutions designed to restore surfaces without causing damage.
Algae
Algae is a common cause of exterior staining, thriving in damp, shaded areas where surfaces stay wet. Green staining appears on render, stone, and cladding, especially on north-facing walls, and can develop at any time if moisture persists.
Chewing Gum
Chewing gum is a common issue in busy areas, creating unsightly and hazardous surfaces. Steam cleaning uses heat and controlled pressure to break down and remove gum quickly without damaging the material beneath.
Graffiti
Graffiti can affect a property’s appearance and is often seen as a sign of neglect. Professional removal uses safe, surface-specific methods to eliminate graffiti while preserving the original finish of the material.
Atmospheric Pollution
Pollution and grime build up on surfaces in urban and high-traffic areas, causing dull, dark staining. Over time, these particles can react with materials like stone, leading to discolouration and gradual surface deterioration.
Moss & Lichen
Moss and lichen grow in damp, shaded conditions and attach to surfaces like roofs, walls, and paving. They retain moisture and cause staining, increasing the risk of long-term surface wear if left untreated.
Carbonate Staining
Carbonate staining, or lime run, appears as hard white or grey deposits on brick or stone. It forms when water carries minerals from mortar joints or cracks and, unlike efflorescence, does not disappear when wet.
Oil & Grease Stains
Oil and grease stains from vehicles or spills can penetrate deep into porous surfaces like concrete and stone. These marks are difficult to remove without professional cleaning that breaks down and lifts the contamination.
Fly Posters & Stickers
Fly posters and stickers can make surfaces look neglected, especially in high-visibility areas. They adhere firmly, but with the right cleaning methods, they can be removed cleanly without leaving residue or damage.
Paint Removal
Paint may need removing due to spills, damage, or restoration work. Specialist cleaning methods safely remove paint from surfaces like brick, stone, and render without causing damage to the underlying material.
Efflorescence
Efflorescence is a white, powdery residue caused by salts rising to the surface of brick or concrete. It often disappears when wet and returns as it dries, affecting the overall appearance if left untreated.
Rust Staining
Rust stains appear as red or brown marks caused by metal oxidising in damp conditions. These stains can spread over time but can be safely removed with the correct cleaning treatment.
