We come across damage from water blasting and washing buildings on a daily basis. Whilst it might seem like anyone can wash a building (and indeed, anyone can try), there are a wide range of skills and tricks to getting it right. The financial difference between having a great job done and damaging valuable property can be very significant.

Tips on Avoiding House Washing Risks

High-pressure water

If water is sprayed in the wrong places, it can make its way into a house or building – causing water damage and electrical issues. Whilst water might seem like a harmless substance, when it is applied under pressure, it becomes a powerful tool which can be quite dangerous if not handled correctly.

House and building washing chemicals

House and building wash chemicals can bleach clothing, decking, curtains and more. When these substances are being used, it’s important that appropriate measures are taken to protect vulnerable materials, remove furniture and protect the surrounding area.

“Sodium Hypochlorite is the main ingredient in laundry bleach. It is used extensively as a bleaching agent in the textile, detergents, and paper and pulp industries… Large quantities are also used as a disinfectant in water and wastewater treatment and sanitary equipment.”

As far as chemical washes go, the correct mix of sodium hypochlorite, water and a liquid citrus surfactant are safe for almost all house washing applications.
Strong herbicides are used for roof treatments. When sprayed on plants, they can be extremely detrimental to their health. If roof treatment chemicals  are not completely rinsed off house surfaces, they have the potential to stain oxidized surfaces and treated window surfaces.

Anyone can call themselves a building washer

To top it all off, the house and building wash industry has low barriers to entry for those looking to get involved – anyone can buy a water blaster and house washing and spraying equipment. There are no formal regulations, and none of the tertiary institutions offer courses to help people improve their skills.
The process of washing a building or house is as much of a skill as it is an art form. Unfortunately, there is a very limited amount of information to learn from and much of the information available is inaccurate.
In order to carry out quality exterior cleaning to a high standard, it’s important to have a mind set  similar to that of a car painter. House wash operators really need to care about the cleaning process and the impact that it can have in order to ensure that their customers are happy long after the job has been completed.
