DAYCO Cleaning is a professional cleaning company offering pressure washing services in and around London.
Pressure washing (also known as power washing) is an effective exterior cleaning method for hard surfaces that removes dirt, pollutant buildup, and biological growth.

Modern pressure washing uses controlled water pressure and, when appropriate, hot water to remove contaminants without damaging surfaces. However, caution is always necessary.
For delicate areas or historic properties, we recommend DOFF cleaning as a gentler alternative to traditional power washing.
Pressure washing is appropriate for a variety of surfaces, and the DAYCO Cleaning team of professionals will evaluate your area to ensure that the most suitable cleaning techniques are used.
In London, pavements become dirty due to heavy foot traffic, chewing gum, spillages, and pollution. Pressure washing restores clean, safe walking surfaces and can reduce slip hazards, particularly in commercial and public areas.
Pressure washing is commonly used to clean brickwork, concrete, stone, and rendered surfaces on urban buildings. High pressure jets remove pollution, algae, moss, and surface grime, improving appearance and helping prevent long-term material degradation.
Courtyards, bin stores, loading bays, service yards, and communal spaces benefit from regular pressure washing services to remove odours, residue, and unsightly build-up.
Pressure washing can be used on hard surfaces around shopfronts, steps, and thresholds to remove grime and enhance kerb appeal in busy city locations. Clean shopfronts and business entrances create a strong first impression for customers.
In London, where construction is ongoing, we frequently use pressure washing to remove dust, mortar residue, and general debris from hard surfaces after building works.
Pressure washing, often combined with hot water or specialised treatments, is an effective method for removing specific types of graffiti from robust urban surfaces such as concrete and paving.
London car parks and forecourts are regularly exposed to oil stains, tyre marks, fuel residue, and dirt. Pressure washing maintains a clean, professional appearance while improving safety and hygiene.
In any area, and especially in the busy, historic city of London, pressure washing must be carried out responsibly to ensure public safety and avoid surface damage. DAYCO Cleaning manages this for you, with our specialist equipment and professional services.
Primarily, we use barriers, cones, and signage to create safe work zones in public areas and high-foot-traffic locations in London. Access equipment, such as mobile towers, MEWPs (Mobile Elevating Work Platforms), or platforms, is necessary when pressure washing at height. It is also crucial to use Personal Protective Equipment (PPE) to ensure our workers’ safety.
Our commercial-grade machines feature adjustable pressure settings for different surfaces and dirt levels. Using hot water, they effectively remove oil, grease, and tough grime that cold water can’t handle. With variable spray nozzles and removable lances, we ensure precise control to avoid surface damage. Extension lances allow us to safely reach high walls and hard-to-access areas without ladders.
To protect surfaces, we sometimes need to use specialised cleaning detergents and degreasers designed to break down oils, algae, moss, and heavy contaminants. Detergents improve grime removal, allowing us to reduce jet-wash pressure during cleaning.
Where possible, DAYCO Cleaning use systems to prevent contaminated water from entering drainage systems. We use protective sheeting and masking materials to protect adjacent surfaces, doors, glazing, and landscaping during cleaning operations.
DAYCO Cleaning begins with a site inspection to assess surface types, condition, and dirtiness. We identify contaminants such as dirt, algae, moss, oil, grease, chewing gum, and pollution buildup.
Based on our assessment, we select the appropriate pressure levels and water temperature for each surface.
Before starting the cleaning process, we protect the surrounding areas, including fixtures, drains, and landscaping. We then set up the pressure-washing equipment and mark safe work zones, ensuring proper water runoff management to prevent blockages or environmental damage.
If necessary, we apply pre-treatment solutions to loosen heavy dirt.
Next, we jet wash hard surfaces such as pavements, concrete, stone, brickwork, and paving. For stubborn stains, grease, or chewing gum, we use hot water pressure washing, paying special attention to walls, façades, steps, ramps, and entrance areas.
We also clean car parks, forecourts, service areas, and loading bays by removing surface algae, moss, and biological growth to minimise slip hazards.
For heavily soiled areas, we provide spot treatment to ensure consistent results, and we always rinse and neutralise treated areas where chemicals are applied.
After the cleaning, we do a final check to ensure surfaces are clean and safe. We tidy the site and remove any protective coverings.
The ideal frequency for jet washing depends on location, footfall or vehicle use, exposure to pollution, and environmental conditions. In urban environments, surfaces are exposed to higher levels of dirt, traffic residue, algae, and general wear, meaning more regular cleaning is often required to maintain safety and appearance.
Surfaces in city areas should usually be jet washed every 3 to 6 months. High foot traffic, vehicle fumes, spills, chewing gum, and pollution quickly dirty pavements, entrances, and communal areas. Busy areas such as shopfronts, forecourts, loading bays, and public walkways may require cleaning every 3 months, or even every 2 months, to maintain a clean, safe appearance.
Outer city and suburban locations generally require jet washing every 6 to 12 months. Lower traffic density and reduced pollution mean surfaces stay cleaner for longer. However, areas with trees, shaded spaces, or nearby green spaces may still experience algae and moss growth, which can increase slip risk and require more frequent maintenance.
Commercial premises often benefit from jet washing 2–4 times per year, depending on usage and visibility. Entrances, car parks, service yards, and communal areas should be cleaned regularly to maintain professional standards, reduce hazards, and protect surfaces from long-term staining or deterioration.
Regular cleaning keeps your property looking good and extends the life of your paving and surfaces. Most residential driveways, patios, and pathways need to be jet washed every 12 to 18 months. If a property experiences heavy vehicle use, has shaded areas, or is near trees, it may require cleaning annually to prevent algae, moss, and stains.
Areas with a high risk of contamination, such as factories and loading bays, may frequently experience oil spills, food waste, or heavy foot traffic. To maintain high hygiene and safety standards, jet washing may be necessary every one to three months. Locations with high traffic, such as bin stores and restaurant forecourts, often require more frequent jet washing and could be as much as daily or weekly.
DAYCO Cleaning can tailor jet washing frequency to your site. A professional assessment can identify the optimal schedule based on surface type, location, and usage, ensuring effective cleaning without unnecessary wear.
