Driveway and concrete cleaning in Perth, cleaned to a sealing standard.

Driveway cleaning in Perth is quoted per job, not off a fixed rate, because the price depends on the surface, the size and how much staining is in it. A tidy plain concrete driveway is quick, while heavy oil, bore water rust or thick moss takes pre-treatment and more time. Send a few photos and your suburb and we will give you a clear, no-obligation price before any work starts, with nothing added on the day.

Not when it is done properly. Damage happens when a surface is over-cleaned: too much pressure, the wrong nozzle, or the lance held too close etches concrete, pits the surface and washes the sand out of paver joints. We match the pressure, nozzle and distance to the surface and use a wide 860mm flat rotary surface cleaner for an even finish, so exposed aggregate is cleaned without dislodging the stones. We clean it back, we do not carve into it.

No hot water, and we don't blast. We clean at ambient temperature with a wide 860mm flat rotary surface cleaner walked evenly across the slab, so the finish is controlled and even rather than gouged. It is still pressure-fed, just matched to the surface and never turned into a lance chewing at the concrete, and delicate surfaces like limestone are dropped right down to a low-pressure soft wash.

Limestone is soft and porous, so high-pressure blasting will chew the surface, open it up and leave it worse than before. We drop right down and soft wash it instead: a low-pressure, wide-fan approach with the cleaning done by dwell time and technique rather than brute force. That lifts the salt bloom, algae and grime off liquid and natural limestone without tearing the face, and leaves it sound and ready to protect.

Oil and grease sit down in the pores, so blasting alone just spreads them and drives them deeper. We pre-treat the marks with an alkaline degreaser, give it dwell time to draw the oil up, then lift it off with the surface cleaner under matched, controlled pressure, no hot water needed. Older, set-in stains can shadow slightly because they have soaked deep into the concrete, and we will always tell you honestly what will clear fully and what will only lighten before we start.

Bore and reticulation water carries iron that oxidises on concrete, limestone and render as an orange or brown rust stain, and it is the number one exterior marking we see in Perth. A hose and a scrub will only lighten it and leave ghosting. We use a purpose iron-dissolving treatment to draw the stain out, then finish with controlled pressure. If your reticulation keeps throwing bore water over the same spot the staining can return, so we will also point out where adjusting the sprinklers, and sealing the surface, keeps it clearer for longer.

Shaded, south-facing and damp slabs stay wet through Perth's wet winter, and that is exactly what moss, mould, algae and lichen need to take hold, which is why they show up on the cold side of the house and under trees. It also makes the surface slippery. We pre-treat it with sodium hypochlorite and wash the growth away, then apply a free biocide post-treatment that kills the moss, mould, algae and lichen and slows its return. It is organic, so it can come back over time, and a light scheduled clean keeps it clearer for longer.

For most Perth driveways about once a year keeps on top of the grime, moss and general build-up before it sets in, and shaded or south-facing areas that green up over winter often suit a clean each spring. A sealed surface stays cleaner between visits because dirt and stains sit on top instead of soaking in, so you are cleaning less often and the job is easier when you do.

A clean makes a bare driveway look new for about a month, then the pores are wide open again and it starts pulling in the next round of oil, rust and grime. Sealing is what makes the result last: it closes the surface so water, stains and salt stay on top and wash off instead of soaking in. Cleaning is the preparation, the seal is the protection, and doing both while the surface is clean and prepped is the point at which it makes the most sense.

That is the classic failure of a solvent-based acrylic sealer, the standard clean-and-seal most Perth operators apply. It lays a film on top of the surface rather than bonding into it, so under UV and trapped moisture it clouds, blushes milky white, flakes and peels, and then it has to be stripped and redone every few years. MineralProtect is different: a penetrating sol-gel that bonds into the surface, so there is no film to peel or go milky, it stays breathable and UV stable, and it is registered under a 10-year guarantee.

You can clean any time of year. Sealing is the part that wants the right weather: mild, dry conditions in late spring or autumn are ideal, because sealing in 40-degree summer heat can make the coating flash off too fast and bubble, and sealing over a wet winter surface traps moisture underneath. New concrete also needs to cure for about 28 days before its first seal. We time the seal to the conditions so it goes down and cures the way it should.

We are chemical-considerate. Most of the work is done by the surface cleaner, matched pressure and technique with biodegradable soaps, and where a treatment is needed for oil, rust or organic growth we use the least aggressive product that will do the job. Before we start we wet down and protect the surrounding plants, lawn and garden beds, and rinse everything down afterwards, so it is safe for your pets, kids and garden once the area has dried.

Yes, we are WA-owned and fully insured, and we clean to a damage-free standard: the right method for the surface so your driveway comes up clean without being etched, pitted or stripped. Cleaning itself is quoted per job. Where we go on to seal the surface, that sealing is registered under our 10-year guarantee, which sits on top of your rights under Australian Consumer Law.
