Is Your Render Making Your Home Look Run Down?

Algae, black mould, and green streaks on rendered walls are incredibly common in the UK climate — and they can make even well-maintained properties look neglected.

Black algae streaks running down rendered walls from the roofline
Green growth and moss colonising the render and making the house look old
Discolouration that simply won’t shift with household cleaners or a garden hose
Staining that devalues your property’s appearance and makes it harder to sell

A professional soft wash clean removes all organic growth and staining from rendered surfaces — and the right post-treatment dramatically slows regrowth.

The treatment is left to work, killing algae, mould, and organic growth from the root.

4

Rinse & Clean

Surfaces rinsed to remove all treated growth and residue, leaving clean render.

5

Post-Treatment

Inhibiting treatment applied to slow future regrowth and extend the life of the clean.

Common Questions

Will pressure washing damage my render?

We do not use high-pressure washing on render. Our soft wash method uses low pressure — safe for all render types including K-Rend, monocouche, and silicone.

How long before the render looks clean?

The soft wash treatment continues to work after application — most growth dies off over 24–72 hours. The full result is often even better a week after treatment.

How often does render need cleaning?

This depends on the render type, colour, and location. Shaded or north-facing walls may need attention every 2–3 years. Our post-treatment helps slow future growth significantly.

Can you clean render in winter?

Yes — our treatments work in cold conditions. We avoid working in freezing temperatures or heavy rain, but most of the UK winter is perfectly suitable for render cleaning.
