Thoughtful exterior care

The right approach for the finish on your wall.

Rendered walls can develop algae, weather-related staining and traffic film. Different render systems have different care requirements. Painted finishes, through-coloured render and insulated systems should not be treated interchangeably or cleaned without checking their condition.

The assessment looks for cracks, blown areas, loose coatings and vulnerable details around windows and vents. Cleaning cannot resolve water ingress or failing render. Where the surface needs repair, that should be dealt with before a cleaning method is agreed.

A suitable low-pressure or soft-washing approach may be proposed for compatible render. Product compatibility, neighbouring materials and run-off need consideration. Abrasive wet blasting is not the default for rendered or insulated walls, even where it may be useful on other parts of a property.

Test cleaning helps establish the expected finish and whether existing colour differences are likely to remain. Your quote should distinguish cleaning from painting, repairs and any longer-term treatment. A clean wall is a fresh starting point, not a guarantee against future organic growth.

Your questions, answered

Is wet blasting suitable for render?

Not as a default. The render system and condition must be checked; a gentler cleaning method is often more appropriate.

Will the green staining disappear immediately?

Results depend on the treatment and the cause of staining. Some changes can develop over time and some marks may remain.

Can you clean a painted wall?

The coating’s condition and compatibility need checking first. Loose or failing paint may need separate repair and redecoration.
