What Is Soft Washing & Why Does It Matter?

Soft washing is a low-pressure cleaning method that uses specialist biodegradable cleaning solutions to safely remove algae, lichen, moss, mould and biological growth from delicate exterior surfaces. Unlike pressure washing, it won’t damage render, painted walls or UPVC.

The cleaning solution penetrates deep into the surface and kills organic growth at the root — meaning results last significantly longer than pressure washing alone. For rendered properties in Wales this is the only safe and effective approach.

Common Questions

FAQs

Is soft washing safe for my render?+

Yes — soft washing is specifically designed for render and delicate surfaces. The low pressure and biodegradable solution will not crack, lift or damage your render in any way.

How long do soft washing results last?+

Because we kill biological growth at the root rather than just removing it from the surface, results typically last 2–5 years depending on the surface type and the local environment.

Are the cleaning solutions safe for my garden?+

Yes — we use biodegradable, eco-friendly solutions that are safe for plants, lawns, pets and people once applied and rinsed. We take care to protect any surrounding planting during the clean.

Can soft washing remove black streaks from render?+

Yes — those black streaks are typically algae or atmospheric pollution. Soft washing is one of the most effective ways to remove them safely and prevent them returning quickly.

My house needs repainting — should I soft wash first?+

Absolutely. Soft washing before repainting removes all biological growth and prepares the surface properly. Paint applied over algae or mould will fail much faster — cleaning first extends the life of the new coat significantly.
