Which surfaces may be suitable for pressure washing?
Sound concrete, selected paving, durable masonry and some exterior hard surfaces may be suitable after a test. Loose render, weak joints, painted finishes, timber, delicate stone, sealed surfaces and areas near exposed electricity may need lower pressure, another method or exclusion.
- Compatible concrete paths, terraces or courtyards
- Selected pavers and durable masonry with sound joints
- Ground-level bin surrounds and parking edges when drainage is controlled
- Outdoor hard surfaces where a small test confirms compatibility
What is checked before pressure washing?
Pressure is only one part of the method. The technician also reviews the nozzle, distance, water flow, runoff, pre-cleaning needs and protection of nearby materials.
How is pressure washing carried out?
The agreed area is isolated, loose debris is removed and a discreet test is completed. Pressure, attachment and distance are adjusted to the surface, while water and debris are managed throughout the work.
Inspect and test
Confirm material, defects, runoff and a compatible test setting.
Control the wash
Work in sections with the agreed pressure, distance and protection.
Manage water
Collect accessible debris, guide remaining water and report damage or stains outside the scope.
How should the area be prepared?
Provide photographs, measurements, material details and the water and drainage arrangement. Move vehicles and fragile objects, close nearby openings and keep residents, customers, children and pets outside the controlled work zone.
- Identify external sockets, lighting, cameras and other electrical equipment.
- Report loose render, cracked paving, weak grout, peeling paint or leaks.
- Remove or secure delicate pots, furniture and decorations.
- Confirm where wash water may drain and whether any drains are blocked.
Pressure washing will not proceed where water may enter electrical equipment, occupied interiors or an uncontrolled sensitive drainage route.
SERVICE BOUNDARIES
What is excluded from pressure washing?
Pressure washing does not include unsafe height access, roof work, paint or coating removal, graffiti treatment, facade repair, waterproofing, drainage repair, hazardous contamination or restoration of damaged surfaces. Delicate or unstable materials may be refused or changed to another cleaning method.
- Roofs, gutters, rope access and unprotected height work
- Paint stripping, sandblasting and graffiti removal
- Timber, delicate stone or weak surfaces without confirmed compatibility
- Electrical, drainage, waterproofing or structural repair
- Guaranteed removal of oil, rust, biological marks or permanent staining
Never assume that more pressure gives a better result. Excessive pressure can damage joints, coatings, stone, render and adjacent property.
What determines the pressure-washing quote?
The quote depends on area, material, condition, test results, water access, runoff control, nearby protection, equipment, labour and location. Exterior cleaning is priced individually and has no fixed public rate.
