Pressure cleaning questions answered

Sandstone can lose grains or surface detail under a jet. Start with a gentle, material-specific trial. Weathered, fretting or heritage stone may need specialist advice rather than an ordinary pressure clean.

No. Stone condition, nozzle, distance, flow, temperature and time on a spot change the effect. A machine setting alone cannot establish that a method is safe.

Ordinary acid cleaning is unsuitable for these acid-sensitive stones. Use a compatible stone-care method and seek specialist advice for stains or etching.

Not necessarily. Stone-look porcelain is a manufactured tile; limestone, sandstone and other natural stones have different care requirements. Identify the actual material first.

Yes. Excessive impact can etch tracks or remove weak cement paste. New, dusty, spalling, coated or repaired concrete needs particular assessment.

Joint condition and the cleaning method matter. Some sand may be disturbed. Re-sanding is separate specialist work, not part of a clean. Product instructions may restrict machine cleaning.

No. Mortar smears, algae, oil and salt deposits are different problems. Use the brick manufacturer’s method for the identified deposit; some bricks and masonry products are unsuitable for ordinary acid cleaning.

Strong jets can damage fibres and leave a furry or striped finish. A suitable cleaner, brushing and gentle rinse may be more appropriate, depending on the timber and coating.

No. Check the exact brand and generation. Some newer products permit controlled pressure cleaning while older products may prohibit it. One product’s maximum pressure is not universal advice.

A compatible low-pressure wash can suit sound coatings. Cracks, loose render and peeling paint need assessment first. Washing cannot repair those defects.

Do not assume that a strong chemical recipe is compatible. Start from the current coating manufacturer’s care advice and assess the actual stain. Low pressure does not make incompatible chemistry safe.

No. We soft wash tile roofs only, and price them after a look at the roof. The tile, coating, pointing and safe access decide whether a clean suits the roof.

High-pressure and steam equipment are not appropriate default methods. Follow the installed panel manufacturer’s instructions, using suitable water and non-abrasive tools with safe access.

No. NSW prohibits pressure washing asbestos material, and we will not pressure wash fibro. You cannot tell an old sheet is safe by looking at it. Have unknown older sheeting checked by a licensed asbestos assessor before anyone disturbs it.

No. The effect depends on how dirty the panels were, their angle, the weather and the system itself. Panel cleaning is separate from electrical inspection and repairs.

No. Surface oil may improve with suitable treatment, while older absorbed oil can leave a shadow. A compatible poultice or repeat process may need a separate scope.

Not with every process. Some leave-on treatments rely on gradual weathering, so the lichen fades over the following months rather than coming off during the visit.

The surrounding area may still be dirty, the material may have natural variation or the treatment may have altered a coating or weak surface. Judge a test patch once it is dry, and clean to a sensible boundary such as a whole slab or wall.

No. Those are material or repair issues. Cleaning may reveal them more clearly; stone restoration, masonry repairs or regrouting need their own scope.

No. Removing contamination may help cleanliness, but surface finish, wear and drainage also affect traction. A wash is not a formal slip test or certification.

Soft washing relies on compatible treatment and low mechanical force. Pressure washing uses controlled water force on suitable surfaces. Both start with checking and testing the surface.

No. Low pressure describes the water force, not the hazards of a product. Compatibility, protective measures, label instructions and safe re-entry requirements still apply.

Heat is useful to assess for oil, grease, food fats and gum on compatible hard surfaces. It is not needed for every job and does not make a delicate material safe to pressure clean.

Not reliably by itself. Those deposits need identification and a compatible targeted treatment. An ordinary descaler may damage acid-sensitive stone or coatings.

A general wash is not automatically validated disinfection. A hygiene claim would need a defined process, contact time, temperature or product and appropriate verification.

No. Joint sand, stripping and sealing are separate specialist jobs with their own materials and drying times. They are not part of our cleaning services.

Single driveway, up to 35 m²: $329. Double driveway, up to 65 m²: $499. Prices include GST. Size limits and the surcharges on the pricing page apply.

Single storey: $549; double storey: $899, including GST, for the stated walls, eaves and downpipes scope. Check property size and access before choosing a package.

It is an approximate range for budgeting. Material condition, stains and access set the final price. It is not a fixed package, and not every surface on the list will suit every property.

Travel, setup and site preparation take time even on a small area. The minimum attended job is $249 including GST; commercial attendance has a separate $450 minimum. A more specific package or site scope may apply.

Yes. All listed prices include GST.

Length alone is incomplete unless the height and number of faces are stated. Face area is length multiplied by height, with each side counted separately.

No. Consider the material, existing sealer, moisture, exposure and intended use. Some installations do not need a new sealer, and an unsuitable product can cause problems.

Once the area has been rinsed and has dried. Product instructions, surface condition and weather change how long that takes. There is no single time that suits every clean.

Use condition and manufacturer guidance. An annual review is a practical starting point; shaded, damp, coastal or heavily used areas may need earlier attention. No treatment stops regrowth for a fixed period.

A working outdoor tap is best. The mobile unit carries 100 metres of hose. Note where the tap is in your booking details. A site with no working tap within 100 metres has a surcharge, shown on the pricing page.

Clear the agreed area of vehicles, movable furniture, toys, washing and loose items where practical. Secure pets, close windows and point out delicate plants, damaged seals and other sensitive features.

Say so in your booking details. Diversion and reconnection follow the instructions for the product used and the tank system, not a fixed waiting period.

No. The NSW EPA’s position is that stormwater drains are for rain only, and polluted wash water must not go into them. A drain cover on its own does not deal with the water.

Check the current Sydney Water guidance. Drinking-water cleaning of hard surfaces is limited to necessary safety, health, emergency, construction or contamination situations. Stormwater protection is a separate requirement.

Say in your booking whether you will be home. If you will not be, add how to reach the work area, where the tap is and anything locked, fenced or guarded by a pet.

Use the online price request. Add the dimensions, wide and close-up photos, product names, coating history, access and any known hazards.
