The What, Why, and How often, of pressure washing your home


Pressure washing, or power washing, cleans vertical and horizontal surfaces using a strong stream of water to remove dirt, grime, dust and debris. It is easy to get hold of a pressure washer, they can be hired if you don’t want to buy one. The high powered water can reach high up a wall, and you probably won’t need to use a ladder. If you don’t want to do it yourself, contact a firm that includes Pressure Washing in its list of services.


Amongst the many benefits of regular pressure washing, is the fact that your home will stay looking great, but as well as this is the preventative maintenance on your home that inhibits the build-up of mould, algae, mildew and grime which can lead to damage. Keep a watch out for signs of mould and combat it as soon as possible.

How often?

To start with, it depends on the climate where you live. Hot or cold, humid or dry, the climate can dictate when you should think about washing the house. In most circumstances, and for best results, a general hose-over at the end of each season would be beneficial. Do it on a calm sunny day, so that the sun can thoroughly dry the house. These would be lightweight “in-between” cleans which will lead to a more substantial cleaning procedure perhaps every year or so. However modern building materials are designed to resist mould and mildew, and may not need to be cleaned so often. A simple answer to “How often” is “as often as you need to”. This, however, also depends on the following factors.

Other factors

If you live near or on a dirt road, it may be necessary to clean more often, particularly in the dry season. Pollution from heavy traffic can have a dulling effect on the appearance of your home. Local industry emitting heavier than air particulates leaves a considerable deposit on the surrounding roofs, walls and pathways over time, and a dull film can develop on the properties. A holiday rental house near the beach is affected by salt water and sand as well as the usual dirt and dust. A good pressure wash on a regular basis will keep it attractive to renters.  A storm may deposit debris and dirt over your property. Even the rain is not always “clean”, and can deposit dirt. Once again, “as often as you need to” applies in these circumstances.

Are you planning to sell your house? Pressure washing will make the house more attractive to potential buyers. Or if you are thinking of painting the house, a good wash will remove grit and dirt and it will be easier to apply the paint to nice, clean, dry surfaces.

Do you have trees close to the house? Be aware of problems from tree sap, foliage, and those who inhabit trees, such as possums and birds, which can leave unsightly deposits on your walls.

So the answer to “How Often” is not cut and dried. There are numerous answers to the question depending on where you live and what happens in your neighbourhood.
