Commercial exterior cleaning is one of the most effective ways to remove dirt, grime, mould, algae, graffiti, and other stubborn contaminants from the outside of your property. At Onshore Property Wash, we use professional-grade high-pressure water blasting equipment combined with specialist cleaning agents to deliver a deep, thorough clean across all types of commercial exterior surfaces — restoring your property to its best and keeping it that way.

Our commercial exterior cleaning process is tailored to the specific needs of each surface and soil type. We work across three core cleaning approaches depending on the condition of your property:

• Surface Cleaning — ideal for regular maintenance cleans, removing everyday dirt, dust, and biological growth from exterior surfaces without aggressive treatment
• Degreasing — specifically suited to commercial and industrial environments such as loading docks, car parks, and factory exteriors where oil, grease, and fuel residues accumulate
• Heavy-Duty Removal — for more demanding jobs including graffiti removal, paint stripping, rust, and deep-set staining on concrete, brick, or metal surfaces

Whatever the condition of your commercial exterior, we have the right technique and equipment to get it clean.

Our high-pressure exterior cleaning systems deliver water at precisely controlled pressures, allowing us to tackle the toughest contaminants without causing damage to the underlying surface. This is a critical distinction — improper cleaning methods can erode surfaces, strip coatings, and shorten the lifespan of your exterior. Our experienced operators understand how to calibrate pressure and technique to suit every surface type, including concrete, brick, masonry, asphalt, metal cladding, and timber.

Contrary to common belief, regular professional exterior cleaning actually extends the life of your surfaces. By removing corrosive substances like mould, algae, oil, and chemical residues before they penetrate and degrade the material, you are actively protecting your asset and reducing long-term maintenance costs.

One of the most common commercial exterior cleaning challenges we address is graffiti removal. Left untreated, graffiti not only damages your brand image but can also encourage further vandalism. Our high-pressure cleaning systems, operating at up to 2000psi, are highly effective at removing spray paint, ink, stickers, and adhesive residue from concrete, brick, and cladding surfaces — restoring your exterior quickly and cleanly with no lasting marks or surface damage.

We also specialise in the removal of marine growth, atmospheric staining, rust streaks, tree sap, and other environmentally deposited contaminants that are common on Auckland commercial properties due to our coastal climate and high humidity.

A key advantage of professional exterior cleaning is that it requires minimal or no chemical intervention. Our high-pressure water systems are capable of breaking up heavy grease, grime, and biological matter through water volume and pressure alone — making it an environmentally responsible cleaning method that is safe for use around stormwater systems, landscaping, and public areas. Where cleaning agents are required, we use only biodegradable, commercially approved products.

Our equipment is also fully operational in any weather conditions, meaning we can keep your scheduled maintenance on track regardless of Auckland’s unpredictable climate. Whether it’s mid-summer or the middle of a wet winter, our team will show up and deliver.

Don’t let the weather delay your maintenance schedule. We operate year-round — get in touch to lock in your clean.
