Concrete Cleaning Allambie Heights

No. We set the pressure to clean the surface without eroding it. If the colour has already faded from age, cleaning will not restore the pigment but it will remove the grime hiding it.

We give a free, no-obligation quote based on the area and condition. Every job is priced individually, with no hidden extras.

It is organic growth, not the concrete ageing. Algae, mould and lichen colonise the porous surface, feeding on moisture, shade and leaf litter. That is why the south side of a slab or the tree-lined end of a driveway always looks worst. Treating the growth and cleaning the pores brings the original surface colour back.

Usually, yes. The brown marks left by wet leaves are tannin stains, and most lift with the right treatment and a thorough machine clean. Very old tannin marks that have soaked deep can leave a faint shadow, and we tell you honestly before we start what will lift fully and what may not.

A standard driveway or patio slab takes a couple of hours, and larger areas, like paths plus driveway plus alfresco, usually fit within half a day. Pre-treatment adds a little time up front but is why the clean lasts. You get a clear timeframe with your free quote.

Every 12 to 18 months keeps most Northern Beaches concrete looking good. Shaded slabs and anything under trees may want a yearly clean, while sunny, open areas stretch longer. Regular cleaning also stops the deep staining that becomes permanent when growth is left for years.

We kill it first. Blasting alone shears the growth off at the surface and leaves the roots alive in the pores, which is why DIY cleans green up again within months. Our pre-treatment kills the mould and algae at the root before we clean, so the result lasts significantly longer.

Access to an outside tap, cleared surfaces, and that is about it. Our machines are petrol powered so we do not need your electricity. Move cars and anything loose off the areas being cleaned, keep pets inside, and we will handle the rest, including protecting the gardens.

Almost never. Damp weather makes no difference to a concrete clean, since the slab is soaked during the process anyway. Only heavy rain or storms cause a reschedule, and in that case we contact you beforehand and move the job to the next clear day at no cost.

It is usually walkable within an hour or two and fully dry the same day, faster than flat driveways because the slope sheds water naturally. We finish by rinsing debris down to the street line and tidying the gutter edge. You can generally drive on it as soon as we pack up. Weather and shade can stretch drying a little in winter.
