Good to know
Render & walls — your questions
Why not just pressure wash render?
High pressure can blow holes in render and strip coatings. Soft washing uses low pressure with a treatment that kills the algae at the root — safe, and far longer-lasting.
How long do the results last?
A soft wash typically keeps render looking clean much longer than pressure washing, because it treats the growth rather than just removing the surface layer.
Will it harm my plants?
No. We wet down and protect planting before and after, and take care throughout the job.
