Frequently Asked Questions

How often should I wash my house?

Most people get their homes washed once per year but this could vary based on a few factors. If you prefer to keep your house looking fresh all year long then yearly is a good choice. We also recommend once per year if you are concerned about algae spores and bacteria in the air then getting your House washed yearly is the best option.


In some cases you can wait 2 years before having your house washing done. It really depends on how much sunlight your house gets and how much shade your exterior cladding gets throughout the day.

How Long will it take to for a House Washing service?

The time to do a house wash in Auckland can vary on many factors including the type of cladding, the size of the house and the water flow of the property. With our quality equipment and techniques a typical house wash project takes between 1-3 hours. 

Are Spray Away Exterior Cleaning chemicals safe for plants, animals, and the environment?

We always make sure to take the best possible care of your plants and property. We go above and beyond to ensure the proper protection of your plants. Our chemicals, when used properly, will not cause any damage to your property. 

Does house washing increase the value of my property?

House washing in most cases will improve the value of your home. We often clean homes for people who plan on selling their house. By washing your home, you improve the curb appeal and the perceived value. It creates a much better first impression for potential buyers and shows your property has been well maintained.


Green algae and dirt build up is a sign that the house may not have been properly cared for and could have other hidden problems. Also making potential buyers think what else will have to be looked at.

Do I need to be home for my services?

You do not need to be home in order for us to perform a house washing service. If you are not home at the completion of the job, we can simply have you take a look around when you are home to confirm that you are satisfied with our work.

What happens if it rains on my day of service?

If we have rain the day your service is booked we will still plan on doing the service as normal. We wash in rain, hail (maybe not) and shine! However, if it is raining heavily then we may have to postpone the washing until our next available day. You will be contacted on the day if there are any problems.

Will your house wash remove the “green stuff” from my cladding?

Yes! We specialize in removing the "green stuff" from your exterior cladding. That green stuff is really just algae growing on your exterior. Our cleaning process not only removes it but it also kills it and keeps it away for a longer time than just pressure washing it.

What is included with a house wash?

When we clean a house it includes much more than just the Cladding. We wash the siding, trim, facia, window sills, out side of gutters, downpipes, garage doors, pillars, windows (rinsed clean, a specific pure water clean is also available), and soffits. Basically from the outside of the gutters to the ground

Does Spray Away Exterior Cleaning clean windows?

Does Spray Away Exterior Cleaning clean brick surfaces?
