Read the guide →Common Questions About Pressure Washing
Quick answers to the questions we hear most often from London property owners and businesses looking to book a professional clean.
-
In London, driveways and patios typically need a professional clean every 12 to 18 months due to higher levels of pollution and damp compared to other parts of the UK. Commercial properties and high-footfall areas may need more frequent cleaning, sometimes every three to six months depending on usage and exposure.
-
No. Surfaces like older brickwork, soft stone, painted render and some types of decking require a lower-pressure soft wash approach rather than full jet washing. A professional assessment before any clean is important to avoid surface damage or mortar erosion. Cloud Nine always assesses surfaces before starting any job.
-
Pressure washing uses high-pressure water to blast away dirt and debris. Soft washing uses lower pressure combined with specialist cleaning solutions that treat biological growth like algae, moss and lichen at the source rather than just removing surface matter. Soft washing is the safer method for roofs, older brick and rendered walls.
-
It can if done incorrectly. Using too high a pressure, the wrong nozzle angle or getting too close to block paving joints can dislodge jointing sand or damage softer surfaces. Professional equipment with the correct settings and an experienced operative eliminates this risk entirely.
-
Not usually. As long as there is access to an external water tap and sufficient drainage, the clean can take place without you being present. The Cloud Nine team will confirm all access requirements before the visit so everything runs smoothly.
