Surface Contamination
Whatever the contaminant, we have the knowledge, expertise, and equipment necessary to guarantee a brilliant exterior clean.
Contaminants
Different surface contaminants often require different treatments. OneFifty has developed a range of tried and tested cleaning processes that help ensure the best possible outcome without damaging the surface material. From graffiti to greasy food stains, or from algae to atmospheric pollution, whatever the contaminant we have the knowledge, expertise, and high performance equipment necessary to guarantee a brilliant exterior clean.
Algae
Algae requires moisture to grow and reproduce so it thrives in damp, sheltered or shaded areas. Growth tends to be more significant in autumn and winter, but can happen at any time if the surface is persistently damp and shady.
Read moreAtmospheric pollution
Atmospheric pollution & general grime is a particular problem in built up areas, such as city centres, where there is a high volume of traffic. This is because vehicle exhausts emit sulphur dioxide which reacts with stone, forming calcium sulphate crystals on the surface.
Read moreCarbonate Staining
Carbonate Staining, or Lime Run, is a hard white or grey surface crust that emanates from mortar joints or runs down from a hole or crack between the brick and the joints. The way to differentiate between Lime Run and Efflorescence is that Lime Run does not disappear when wet.
Read moreChewing Gum
Towns and cities are becoming increasingly blighted by blobs of unsightly, hazardous discarded gum. Steam cleaning system makes really light work of the removing the gum; the mix of steam and pressure is a killer combination that is both efficient and effective.
Read moreFly Posters
Fly posters and self adhesive stickers are an annoying problem however these can be quickly and easily removed. They tend to appear on walls and other surfaces in prominent positions - they are advertising after all so want to be seen! We can clean fly posters off quickly and easily.
Read moreGraffiti
Dealing with unwanted graffiti is an ongoing challenge in many urban areas. It is unsightly, can be offensive and is often seen as a clear sign that a neighbourhood is starting to go downhill.
Read moreMoss and Lichen
Moss and lichen are micro-organisms which adhere to a solid surface. Both require moisture to grow and reproduce, so thrive in damp, sheltered or shaded areas. Poor drainage conditions contribute to growth on paths and hard surfaces, moss particularly likes a pitted surface that allows it to set down roots.
Read moreOil and Grease
Greasy food stains, or oil stains from vehicles, can be surprisingly stubborn and difficult to remove - especially from porous surfaces such as wood, natural stone and concrete.
Read morePaint
There can be several different reasons for wanting to remove paint from an exterior surface; perhaps to clean up after a spill or to remove old paint from a building façade. More recently, we are receiving requests to remove paint after a paint attack.
Read moreRust Staining
Rust is commonly found on buildings constructed with iron, steel and other types of metals. Red-brown or yellow-brown rust patches appear on facades as a result of oxidisation of the metal within or nearby, which is caused by moisture and dampness around it.
Read moreWhite Efflorescence
White Efflorescence, a naturally occurring phenomenon on brick, concrete or stone walls and floors, is a loose, powder surface deposit. It usually disappears when the surface is wet and then reappears as the surface dries.
