The problem
Render, masonry and paving weather differently, but each can collect dirt, organic growth and local staining. A dark mark may be surface contamination, a failed paint finish or a sign of another defect. Cleaning should be matched to the material and should not be sold as a substitute for repair or repainting where those are actually needed.
What's involved
- 01Identifying each surface and any paint, sealer, pointing or visible damage
- 02Agreeing a suitable cleaning approach for the render, wall or paving area
- 03Protecting adjoining elements and working through the agreed elevations or zones
- 04Treating local marks only where the surface and stain make that appropriate
- 05Reviewing the cleaned areas and tidying the immediate work zone

FAQ
Can painted render be cleaned?
Often it can, but the paint condition and render beneath it need to be checked. Loose, cracked or poorly bonded finishes may need repair or repainting rather than stronger cleaning.
Will black or rust staining disappear completely?
Not always. The source, age and depth of a mark affect the outcome. Testing can help set a realistic expectation before a larger area is treated.
Can walls and patios be cleaned during the same project?
Yes, they can be assessed together. Because they may be different materials, the quote should still define the treatment and area for each surface.
How often should exterior surfaces be cleaned?
That depends on shade, exposure, planting, traffic and the surface finish. We can discuss maintenance after seeing how the particular property weathers.
