Softwashing for render, K-Rend and cladding

Green and red algae on a wall is alive. Pressure washing pushes it around and gouges the render; softwashing kills it with a Benz biocide at low pressure, so the wall comes back to its own colour and stays that way for years.

How it is done

The Swift Cleaning method.

  1. Pre-drench the garden

    Grass, plants and shrubs are soaked with fresh water before and during the treatment so they don't take up the biocide.

  2. Apply at low pressure

    The biocide goes onto render, K-Rend, cladding or painted plaster with no mechanical force on the surface.

  3. Rinse and leave it safe

    Surrounding areas are rinsed afterwards. Once the surface is dry it is safe for children and pets.

Why it matters

Why it is worth doing properly.

Gentle on the render

Approved biocides go on at low pressure and lift heavy red and green algae without touching the render's texture.

No repainting needed

Coloured render comes back to its original colour, which saves the cost of painting a wall that only needed cleaning.

Protection that lasts

What is left behind keeps sanitising the surface, so airborne spores struggle to settle again for years.

Was let down by another company and Michael had both gutters and windows of my own house, and my mother's house cleaned in 24hrs. Couldn't recommend him and his company more, so professional and efficient!

They always do a great job iv had them in a few times over the last few years and wouldn't get anybody else. Micheal is a top man very easy to deal with.
Jesse GriffinGoogle review
David did a great job cleaning our windows, soffits and gutters. Communication was easy and he arrived exactly on time and payment was really straightforward. I'd highly recommend Swift Cleaning and hope to have them back again to do a few more jobs.

FAQ

Softwashing questions

Why softwash instead of power washing?

High pressure can strip coatings, force water behind slates and gouge render like K-Rend. Softwashing uses low pressure with Benz Softwash biocides to kill algae and moss at the root, so it cleans deeper with no damage.

How long do the results last?

Usually two to four times longer than a power wash, because the spores are killed rather than moved around. Render usually stays clear for 2 to 4 years, and a full roof softwash comes with the written 3-year moss-free guarantee.

How soon will I see a difference?

Red and green algae on render dissolves almost straight away. Heavy moss and black lichen on a roof die on contact, turn white or brown and wash off with the rain over the following weeks.
