When it comes to soft washing, render cleaning and roof cleaning, some companies profess to be fully trained and it would be a good question for a customer to ask ’trained by who and which institution?’
It is crucial you choose a professionally trained capable company, that can work legally to current safety standards and efficiently work on your property at heights with the right equipment. Also will use the right professional chemicals for what they intended.

Render on builds originates from Europe and comes in many forms from just simple sand and cement to coloured K-render.
Most render is used to improve the aesthetics of a property and now has become far more common on new builds in the UK.
ALGAE: WHAT IT IS AND WHY IT OCCURS
Unfortunately unlike the European climate, we are exposed to more extreme types of weather and do suffer from a more damper more overcast climate which does make for ideal conditions for introducing bio-film colonisation.
This can vary from dulling of render to full discolouration and in many cases turning a rusty colour is known as red algae (Trentepohlia).
In other cases, black unsightly discolouring blotch lines run from window ledges and protruding edges. This algae is fast spreading and very resistant, known as black algae (Aspergillus Niger)
Added to this, areas like stone window ledges and cornerstone can suffer from an invasion of Lichen in its many forms from gold Lichen (Caloplaca flavescens) to white lichen (Diploicia Canescens) and map lichen (Rhizocarpon Geograhicum)
The longer these are left to adhere, develop and maturate, the more bio-corrosive active they will become. All have lived on this planet for millions of years and are tough and extremely resilient!
THE TRADITIONAL METHOD!
Many UK cleaning companies used Sodium Hypocrite (SH or Hypo) It works instantly, however, it’s a very harmful chemical with a strong bleaching effect.
Some even use cheap SH that is label compliant for farming or even swimming pools, but not for render. This is a cheaper option and will have no liability from either the manufacturer or their business insurance!!
But could explain why some quotes are so much cheaper!
ACTIVE CLEANING SERVICES SAFER ALTERNATIVE
We can then select one of our professional grade, label compliant. fully licensed biocide treatments
The biocide kills the biofilms at the cell wall level by piercing through them, penetrating the organism and killing it all the way down to the root system.
After it dies it then biodegrades. In addition, the biocide continues to disinfect, prolonging any regrowth.
Once dry the solution is PH neutral and safe for your pets. The process is not instant and normally takes 6/8 weeks. After this time we can come back to check and retreat any patches.
We keep in regular contact with our customers and at any point, we would be happy to schedule another inspection and re-treat with biocide if needed.
We recommend every couple of years to proactively keep your render clean and moss and bio-film free for years!
We would be more than happy to give you a full site survey and produce risk assessments and method statements where required, to reassure you that you and your business are in safe and competent hands!
