House Washing

House Washing

Using our Chemwash low-pressure washing system (also referred to as soft washing) we can clean all types of house exteriors including siding, weatherboard, brick, plaster and more, producing amazing results every time. Soft washing avoids surface damage, paint chipping or potential leaks. We can also safely and professionally clean your exterior windows as part of your house wash. Our low pressure system ensures glistening, streak-free windows every time, with no risk of breakage.

Regular house washing also is vital to clean away moss, mould & lichen from the exterior surfaces around your home. This will prolong the life of your paint and exterior materials. Water alone can sometimes not remove mould, however our specialised house washing detergents will also sterilise surfaces, making it difficult for mould to set in again.

Frequently Asked Questions

Is Chemwash the same as using a water blaster? I don’t want my paint ruined.

Nope, we don’t use any high-pressure water blasting. Our whole system is based around low-pressure cleaning. This is designed specifically to avoid the damage that water blasting can cause, while producing the same results, if not better. We ease away mould, grime, and lichen using biodegradable detergents and gentle pressure, so your paint, cladding, and seals stay safe. If anything, you’ll be helping your paint last longer.

How much does a house wash cost? I don’t want to get stung.

We clean homes of all shapes and sizes, so when it comes to costs for your property, we don’t guess. Instead, we provide customised quotes that are free, fast, and no-obligation. We’re upfront with pricing too, so there’s no surprises later on.

Will your products harm my plants, pets, or family?

No, our detergents are designed to be safe around the environment, pets, and people. In fact, we do house washing for family homes every day, so you have nothing to worry about. If you’ve got pets, we do suggest keeping them inside while the wash is happening, but we’ll give you simple heads-up instructions closer to the time.

My place is pretty dirty… are you sure you can get it looking good again?

Absolutely. You’d be surprised what we can do. We clean homes of every age and condition, including places that haven’t been washed in years. Mould, grime, pollen, cobwebs… it all goes. Most people say their place looks ‘new again’, and neighbours often ring us after seeing the results next door.

How long will the house stay clean for?

Most homes stay looking great for up to 12 months. That said, we’re always happy to provide a more detailed estimate based on your home and environment. If you pair a house wash with a spider treatment, it keeps things even cleaner, with fewer cobwebs returning.

Do I need to be home when you do the wash?

Not at all. As long as we’ve got access to water and the exterior is ready, you don’t need to stay home. We’ll give you a heads-up about when we’re coming, but you don’t need to be there when we arrive. You can just come home to a sparkling clean house!

Is a professional house wash actually worth it? Can’t I just DIY it?

You can, but DIY water blasting often leads to things like patchy cleans, stripped paint, water forced behind cladding, and short-term results. Our low-pressure system avoids all of that and gives you long-lasting, even results, without the risk. Most homeowners choose Chemwash because it’s safer, faster, and the finish looks noticeably better.
