What Are the Benefits of Low-Pressure House Washing?

Low-pressure house washing (or soft washing) has many benefits, and many homeowners we talk to see it as a worthwhile investment. Here are a few key advantages you can expect:

  1. House washing keeps your home looking like new through the removal of dirt and stubborn stains. Say goodbye to that unsightly grime and build up! Customers are often surprised at the great results we can achieve.
  2. Soft washing is much safer than high-pressure water blasting. Traditional water blasting oftens cause damage to exterior surfaces, relying on sheer force to do all the hard work. Low-pressure cleaning is designed to target the grime and build-up only, while being gentle on actual surfaces.
  3. Our methods are designed to protect surfaces and paintwork long-term, which increases their longevity. Our detergents don’t just remove natural growths and harmful bacteria, they also prevent them from coming back as quickly. Annual house washing is also required for paint warranties from leading brands such as Resene and Dulux.
  4. Low-pressure washing uses significantly less water than traditional water blasting. This prevents unnecessary water wastage, which is kinder to the environment.
  5. House washing is ideal if you are planning to sell your home. It helps you present your property at its best, and demonstrate that it is well-maintained, which can encourage stringer offers from potential buyers.

And that’s not all! With Chemwash, you get experienced local experts backed by a leading national brand. We’re all about great results, safe practices, and friendly service. Get your free house washing quote today.

What Is Soft Washing?

Soft washing is simply another name for the low-pressure exterior cleaning method that Chemwash uses for house washing.

Instead of attempting to blast dirt and growth from a surface using water pressure alone, soft washing combines specialised environmentally-friendly detergents with controlled, low-pressure water. The detergents help break down dirt, grime, mould, algae and other organic build-up. The exterior is then gently rinsed to leave the surface clean.

This means soft washing is particularly useful if you are wanting to protect your home’s paintwork, cladding, timber, brick, or other finishes.

Is Chemwash House Washing Environmentally-Friendly?

Effective exterior cleaning should also be considerate of the environment around your home.

That’s why Chemwash uses biodegradable, salt-based detergents developed by a leading industrial chemist. They are specially designed to be tough on dirt and grime, gentle on surfaces, and completely safe for use around people, pets and plants.

In addition, our low-pressure cleaning system uses less water than traditional high-pressure water blasting, which is another environmental advantage. It’s all part of Chemwash’s ongoing commitment to delivering effective house washing with the lowest possible environmental impact.

How Often Should You Get Your House Washed?

Generally speaking, most kiwi homeowners get their house washed every 12 months, though this can vary from property to property. How frequently a house should be washed depends on factors like location, materials, and surrounding environment.

For example, homes in damp, shaded or exposed locations may develop exterior build-up more quickly than properties in other areas. This may mean that a house wash every 6-8 months is more suitable. Different cladding and paint systems can also have different maintenance requirements.

If you’re not sure how long the results of a house wash will last, your local Chemwash team can provide informed estimates based on your specific property and environment.

How Long Does House Washing Take?

House washing times can vary from a couple of hours for a small house up to a full day for larger or more complex properties.

The materials your home is made from can also influence the time taken. For example, a cedar house generally takes longer to clean, while weatherboards are comparatively fast. Other factors that can affect how long your house wash takes include accessibility, how much build-up there is, and weather conditions.
