Preparing your property for professional exterior cleaning takes about 30 minutes and makes a meaningful difference to the quality of results you receive. A well-prepared property allows the cleaning team to work safely, efficiently, and thoroughly, ensuring every surface gets the attention it needs without delays or obstacles. This guide covers everything you need to do before, during, and after your scheduled clean.
Why Preparation Matters
Professional exterior cleaning involves specialised equipment, cleaning solutions, and high-pressure or low-pressure water systems. The process is most effective when the cleaning team has clear, unobstructed access to every surface being treated. A small amount of preparation on your part delivers four key benefits.
Safety. Removing obstacles from walkways, driveways, and around the perimeter of the building eliminates trip hazards and ensures the team can move safely while carrying equipment and hoses. Exterior cleaning often involves wet surfaces, and a clear work area reduces the risk of slips and falls for both the operators and your household.
Protection of your belongings. Outdoor furniture, decorative items, potted plants, and vehicles can all be affected by cleaning solution overspray or water runoff. Moving or covering these items before the clean prevents any accidental damage or discolouration.
Better cleaning results. When surfaces are fully accessible, the cleaning team can achieve complete and even coverage. Items left against walls, on driveways, or in walkways create shadows and missed patches that compromise the final result.
Faster completion. A prepared property allows the team to begin work immediately upon arrival rather than spending time moving items, working around obstacles, or waiting for access. This means the job is completed sooner and with less disruption to your day.
Before the Cleaning Day: Your Preparation Checklist
Around the Property
Walk the perimeter of your property and clear any items that are leaning against walls, sitting on paths, or obstructing access to the areas being cleaned. This includes outdoor furniture, barbecues, garden tools, bikes, toys, pot plants, bins, and stored materials. Move these items to a covered area or to a section of the property that is not being cleaned. If items are too heavy to move, let your cleaning operator know in advance so they can plan around them.
Check that all gates are unlocked and accessible. If the cleaning team needs to access the side of the house, rear yard, or any gated area, ensure they can get through without delay. If you have a coded lock or security gate, provide the code or arrange for the gate to be left open.
Vehicles and Driveways
Move all vehicles off the driveway and away from the areas being cleaned. Park them on the street or in a location that is well clear of the work zone. Cleaning solution overspray and high-pressure water mist can settle on vehicle surfaces, and while professional operators take precautions, the safest approach is to remove vehicles from the area entirely. If your driveway is being pressure washed, the entire surface needs to be clear for the cleaning team to deliver an even, streak-free result.
Plants and Gardens
Move potted plants away from walls, driveways, and paths that are being cleaned. Potted plants positioned against walls are particularly important to move, as cleaning solution applied to the wall surface will run down and pool around anything at the base. In-ground garden beds directly adjacent to walls being cleaned will be pre-wet and protected by the cleaning team as part of their standard process, but you can help by giving any delicate or newly planted specimens a thorough watering the evening before the clean. Well-hydrated plants are more resistant to incidental chemical contact.
Windows and Doors
Close all windows and doors before the cleaning team arrives. This prevents water and cleaning solution from entering your home. Pay particular attention to louvre windows, which may not seal completely, and any windows that are known to have compromised seals or weatherstripping. If you have window-mounted air conditioning units, close the external vents. Sliding doors should be fully closed and locked. Check that any pet doors or cat flaps are also secured.
Pets and Children
Keep pets indoors or in a secure area away from the work zone for the duration of the clean. Exterior cleaning involves chemicals, wet surfaces, high-pressure equipment, and hoses that create both safety hazards and sources of curiosity for animals. Dogs in particular should be kept well away from the cleaning area, both for their safety and to allow the team to work without interruption. The same applies to young children. The work area should be treated as an active worksite and kept clear of anyone not involved in the cleaning.
Utilities
Ensure that an accessible outdoor tap is available for the cleaning team to connect their water supply. If your only outdoor tap is in a locked area, provide access in advance. Check that the tap is in working order and that the water pressure is adequate. If you are aware of any outdoor electrical outlets, light fittings, or switchboards in the cleaning area, point these out to the team leader on arrival so they can take appropriate precautions around electrical infrastructure.
What to Expect on the Day
Arrival and walk-around. Your cleaning team will arrive at the scheduled time and begin with a walk-around of the property. This is an opportunity for them to assess the surfaces, confirm the scope of work, identify any areas of concern, and discuss the plan with you. If you have specific areas of concern or surfaces you want to draw attention to, this is the time to raise them. The walk-around typically takes 10 to 15 minutes.
Timeframes. A standard residential exterior clean takes between three and six hours depending on the property size and the scope of work. A roof softwash typically takes two to three hours. Driveway and path pressure washing can range from one to three hours depending on total area. A full property clean combining softwash and pressure washing across multiple surfaces may take a full day for larger properties.
Noise. Pressure washing equipment generates moderate to loud noise, comparable to a petrol lawn mower. Softwash application is significantly quieter, as it uses low-pressure pumps. If you are working from home or have noise-sensitive neighbours, be aware that the noisiest phase of the clean will be the pressure washing component. Let your neighbours know in advance if the work is scheduled during the week.
Water usage. Professional exterior cleaning uses a significant volume of water, typically between 500 and 2,000 litres for a standard residential property depending on the scope of work. If your property is on tank water rather than mains supply, discuss this with your operator in advance so water usage can be managed appropriately. Some operators can bring their own water supply for tank-water properties.
After the Clean
Drying time. Cleaned surfaces will be wet immediately after the job and typically dry within two to four hours in normal conditions. Avoid walking on freshly cleaned driveways and paths until they are fully dry, as wet cleaned surfaces can be slippery. In cooler or overcast conditions, drying may take longer.
Rinsing plants. While your cleaning team will rinse adjacent garden beds and vegetation as part of their process, you can give surrounding plants an additional watering after the team has left. This provides an extra measure of protection and ensures any residual cleaning solution is fully diluted and flushed from the soil.
Inspect results. Walk the property after the clean and inspect the results while the team is still on site, if possible. A professional operator will welcome your feedback and address any areas you feel need additional attention before they leave. This is the ideal time to ask questions about maintenance or to flag any concerns.
Softwash ongoing action. If your property received a softwash treatment, it is important to understand that the cleaning solution continues to work after application. You may notice additional improvement in the days and weeks following the clean as the residual solution continues to break down any remaining biological material. Some surfaces, particularly those with heavy lichen coverage, may take up to four to six weeks to reach their final clean appearance as the dead biological matter gradually washes away with natural rainfall. This is normal and expected.
Frequently Asked Questions
How long does exterior cleaning take?
A standard residential exterior clean typically takes between three and six hours, depending on the size of the property, the number of surfaces being cleaned, and the severity of biological growth. Larger properties or those with heavy mould, algae, or lichen coverage may require a full day. Your operator will provide a time estimate during the initial assessment so you can plan accordingly.
Is exterior cleaning safe for my garden?
Yes, when carried out by a professional operator. Before any cleaning solutions are applied, surrounding garden beds, plants, and lawns are thoroughly pre-wet with fresh water. This saturation prevents the plants from absorbing cleaning solution through their roots. Vegetation is also rinsed again after the cleaning is complete. These precautions are a standard part of the process and are effective at protecting your garden.
Do I need to be home during the clean?
You do not need to be present for the entire clean, but we do recommend being available at the start for the initial walk-around and at the end for the final inspection. If you cannot be home, we can arrange access in advance and communicate via phone throughout the job. We will always walk you through the results before we leave if you are available.
What if it rains on the scheduled day?
Light rain generally does not affect the cleaning process. Softwash solutions are formulated to adhere to surfaces even in damp conditions, and pressure washing is unaffected by rain. However, heavy rainfall or storms may require rescheduling for safety reasons, particularly if roof or elevated work is involved. We will contact you in advance if weather conditions require a change of date.
