When you want your building cleaning get in touch

Why should I get my building softwashed?

First things first – if you have a rendered wall, you really shouldn’t be getting it pressure washed.  See our article on why not. You also should not be getting it painted.  Softwashing is safer, quicker and almost always a lot cheaper than painting.

Softwashing is the process of chemical cleaning render to remove all types of organic growth.  Whether its un-slightly green, red or black growth on your render, Adams & Hardcastle can safely remove this whilst causing no damage to the surface below.

The initial stage is to “steam off” areas of particularly heavy soiling with super heated water at very low pressure.  The second stage is to apply the RIGHT chemical at the RIGHT concentration, and allow it to dwell for the RIGHT amount of time.  This is where you need Adams & Hardcastle.  We have extensive training and experience to know the precise details of how best to carry out chemical cleaning specific to your render.  Depending on the chemical used – this may be the process finished.  The chemical will act on live growth and then over the coming weeks you will see your render come back to its former glory! There may be a third stage required which is to “steam off” again to rinse down the render and neutralise any remaining active chemical.  This is the more immediate finish and is appropriate in some cases. 

Get in touch and ask us about a soft washing solution for your render!
