About soft washing
Soft washing is not a weaker version of pressure washing — it is a different approach to a different problem. Instead of relying on force, the surface is treated with a cleaning solution that kills algae, moss and lichen at the root, left to work, then rinsed at a pressure the material can take. Christie's Exterior Cleaning Ltd uses it on roofs, render, harling and anything porous or fragile, because a high-pressure lance on those surfaces strips the finish, drives water where it should not go and leaves you with a bigger problem than the one you started with.
Signs you need soft washing
Green or black growth on a roof, render or harled wall, red algae staining on pale render, dark streaking down a wall or roof slope, or any surface that looks like it needs cleaning but that you would not want a pressure washer near. If you are unsure which method your property needs, that is exactly what the quote is for.
Our soft washing options
Christie's Exterior Cleaning Ltd soft washes tiled, slate, shingle and metal roofs, smooth and textured render, pebbledash, harling and painted walls. Hard surfaces like driveways and patios are a different job — those take pressure washing. Soft washing is often combined with a gutter clear, since growth comes down into the gutters during the job.

Soft Washing for Edinburgh homes
Christie's Exterior Cleaning Ltd has soft washed roofs in Edinburgh, Musselburgh, Livingston, Dunbar and Melrose, and treated them with an HSE-approved biocide afterwards for long-lasting protection. The same method took years of red algae staining off a rendered house in Tranent and a dirt-covered wall in Hawick. Central Scotland's damp climate is why this method matters here more than it does in drier parts of the UK.
What to expect
Christie's Exterior Cleaning looks at the surface and its condition first, because the whole point of soft washing is matching the method to the material. Surrounding planting, windows and doors are protected, the treatment is applied and given time to work on the growth, then the surface is rinsed at controlled low pressure. Larger areas are worked in sections so nothing dries before it is rinsed. Where the roof is carrying heavy moss rather than algae, we will tell you it needs scraping first rather than selling you a wash that will not shift it.
- Assess the surface and confirm soft washing is the right method for it.
- Protect planting, windows, doors and surrounding surfaces.
- Apply the treatment and allow it to work on the growth.
- Rinse at controlled low pressure, working in sections, and tidy up.
