FREQUENTLY ASKED QUESTIONS
Quick answers to common questions about our roof cleaning, pressure cleaning and exterior cleaning services in Perth.
Roof cleaning costs in Perth depend on the size of the roof, roof material, pitch, access and the amount of moss, lichen and dirt present. Jet Force provides tailored roof cleaning quotes based on the individual property. In many cases, we can measure your roof using aerial imagery and provide an estimate without needing to visit first. Gutter cleaning, solar panel cleaning and biocide treatments can also be added if required.
Yes, when the correct equipment and cleaning method are used. Not every roof should be cleaned at the same pressure. Concrete roof tiles can often be professionally pressure cleaned, while older, fragile, clay or terracotta tiles may require a more controlled approach. Before cleaning, Jet Force inspects the roof and selects the most appropriate method based on the roof material, condition and level of moss or lichen present.
The cost of pressure cleaning in Perth depends on the size of the area, surface type and level of staining or organic growth. Driveways, patios, limestone, brick pavers and pool surrounds can all require slightly different cleaning methods. Jet Force provides fixed quotes based on the areas you would like cleaned, and we can often measure larger areas remotely from your address.
Pressure cleaning uses water pressure to physically remove dirt, moss, algae and grime from durable surfaces such as concrete, paving and suitable roof tiles. Soft washing uses lower pressure combined with professional cleaning solutions to treat organic growth more gently. The right method depends on the surface being cleaned. Jet Force uses both pressure cleaning and soft washing across Perth to achieve effective results while protecting the surface.
Roof moss and lichen can be removed using professional roof cleaning combined with appropriate chemical treatment. Depending on the roof type and condition, this may involve pressure cleaning, soft washing or a combination of both. Jet Force can also apply a biocide treatment after cleaning to target remaining organic spores and help slow the return of moss, lichen and algae, keeping the roof cleaner for longer.
Colorbond and other metal roofs require a gentler cleaning approach than many tiled roofs. Jet Force does not use aggressive high pressure on Colorbond roofing. Instead, controlled low-pressure cleaning and suitable cleaning solutions can be used to remove dirt, organic growth and surface contamination while reducing the risk of damaging the roof coating.
There is no set timeframe for every property. How often a roof needs cleaning depends on surrounding trees, shade, moisture, roof material and how quickly moss, lichen or algae develop. Roofs in shaded or leafy areas may require cleaning more frequently than exposed roofs. Regular roof cleaning can improve the appearance of your property and prevent heavy organic growth from becoming established over time.
Clay and terracotta roof tiles can be cleaned, but extra care is required. Older or delicate tiles may not be suitable for aggressive high-pressure cleaning. Jet Force assesses the roof first and adjusts the cleaning method according to the condition of the tiles. In some cases, a controlled pressure clean or soft wash treatment may be more appropriate. Biocide treatment can also be used to control moss, lichen and organic growth.
Gutter cleaning can be added to any Jet Force roof cleaning service. This includes removing debris from the gutters and flushing the downpipes to help ensure water can drain correctly. Roof cleaning and gutter cleaning are often completed together, particularly where moss, leaves and debris have accumulated around the roof. Solar panel cleaning and biocide treatment can also be added to your roof cleaning quote.
Driveway pressure cleaning prices depend mainly on the driveway size, surface and condition. A heavily stained driveway or an area with significant mould, algae or weeds may require additional chemical treatment. Jet Force provides professional driveway pressure cleaning across Perth using commercial-grade equipment to remove built-up grime and restore the appearance of concrete, exposed aggregate, brick paving and other outdoor surfaces.
Yes. Jet Force provides professional limestone pressure cleaning across Perth for patios, pool surrounds, pathways and outdoor entertaining areas. Limestone is porous and can develop mould, algae, dirt and dark staining over time, so the pressure and cleaning method need to be carefully controlled. Chemical treatment can also be used where necessary. Limestone can then be protected with a suitable penetrating sealer if required.
Professional pressure cleaning can remove a significant amount of mould, algae, dirt and organic staining from outdoor paving. Chemical treatment may also be used to help treat growth embedded within porous surfaces. Results depend on the material and the cause of the staining, so some permanent discolouration may remain on older or heavily weathered paving. Jet Force selects the cleaning method based on the surface and its condition.
Sealing pavers after pressure cleaning can help protect the surface from moisture, weathering and future staining. A quality penetrating sealer absorbs into the surface rather than simply leaving a coating on top. This can make pavers easier to maintain and slow the return of mould and algae. Jet Force offers professional paver cleaning and sealing across Perth for limestone, concrete and other suitable outdoor surfaces.
Pressure cleaning can significantly improve oil stains on driveways, but the final result depends on how long the oil has been present and how deeply it has soaked into the surface. Concrete, exposed aggregate and paving are porous, so older oil stains can penetrate below the surface and may not disappear completely. Jet Force can use professional degreasers and targeted chemical treatment alongside pressure cleaning to achieve the best possible result. We’ll always let you know beforehand if a stain is likely to remain visible.
In many cases, yes. Pressure cleaning can remove some of the jointing sand between brick pavers, particularly where the existing sand is loose or already low. Re-sanding helps refill the joints, support the pavers and leave the area looking properly finished after cleaning. Jet Force offers paver re-sanding across Perth using suitable jointing sand, and we can include it as part of your paver cleaning service if required.
