House Washing Whangarei and Northland

No, if the operator has had the correct training in washing techniques and using the machinery and tools correctly. Using commercial grade purpose-built equipment combined with the correct low pressure is important to ensure there is no damage. We also have a variety of nozzles that we use and change for different surfaces. All our guys are thoroughly trained in the correct washing techniques and how to operate the gear.

Water blasting to strip paint is not something we recommend. However, we do recommend and offer a pre paint wash which will loosen and remove any paint flakes making it easier for the pre paint preparation. A lot of residential and commercial house painters will use our services prior to them starting the job.

If you are on tank water for your drinking water, then the answer is yes, it is provided the downpipes are disconnected from the water tank and stay disconnected until there has been 25 ml of rain. Before reconnecting the tank, you can check the water coming off the roof has no smell or foaming. If smell or foaming occurs do not connect the tank until the water runs, clear. 

If we have only washed the roof but not applied a treatment the tanks can be reconnected straight after the wash.

The paint will only chip off if the surface that is being washed has a bad paint finish. This is because we never use a high pressure wash on painted or natural wood surfaces. The nozzles we use are different to that of a domestic water blaster and enable us to do a much gentler wash. We also apply a cleaning product to the surface prior to doing a soft wash which loosens any dirt, grime and mould.

We apply a wash-down product before the wash that does a lot of the work and loosens girt, grime and mould. We then use special nozzles when we wash cladding, enabling us to do a soft wash. We will apply a slow-release agent to the areas on the cladding where the paint is peeling or looks fragile instead of a wash. This means that it will not look clean in these areas after they finish, but the mould etc, will disappear. Sometimes it can take a few weeks till it cleans up, depending on the type of mould and the severity.

We cannot guarantee that no paint will chip as it depends on the paint's integrity, but we take significant measures to avoid it from happening. If a bit comes off in an area, this is when we stop washing and treat the area instead. 

Paint that is old and has been compromised by mould or other factors will often have stains that we cannot remove.

Roof Treatment versus a roof wash. There are a couple of options for getting a roof clean, and the option that will suit you depends on your end goal. Are you planning on having the roof painted after the wash? Or do you want to wash it because it is due for a clean?  

If it is the latter, a roof treatment could be a much better option for you as it's cheaper than a roof wash. Some of the other benefits are that it's quicker and less labour intensive. It's also gentler on roofing materials and uses much less water. You might find this helpful as it provides some information on what a treatment involves, the process and the benefits of a roof treatment vs a wash.

If your situation requires a roof wash instead, 9 times out of 10, we do not require scaffolding. Our guys will use a fall arrest system with harnesses and strops to wash the roof. They are fully trained at Working at Heights and using the fall rest systems. Here is some information about roof washes.
