Natural stone cleaning

What stone cleaning with us looks like

Every natural stone behaves differently. Bluestone is dense but marks with rust and oil. Slate flakes if it's blasted. Granite takes pressure well, while marble and other calcium-based stones etch with the wrong cleaner. Treating them all the same is how stone gets damaged.

We identify the stone, test the cleaner on a hidden spot and set the pressure for that surface. Sandstone, travertine and limestone have their own pages, because they're the stones we see most and each one needs its own approach.

Why it matters

What you get

Stone identified first

We work out what the stone is before choosing a cleaner or a pressure.

No etching

Acid-sensitive stones like marble only get pH-neutral products.

Face kept intact

Low pressure on slate and soft stone stops flaking and pitting.

Stains treated

Rust, oil, tannin and mould each get their own treatment.

Google review, Karen

Excellent service! Nathan is punctual and nothing is a problem.

Step 04 of 04

Rinse and inspect

A full rinse, then a check of joints, chips and any sealer left on the stone.

Why the stone type matters

Dense stones such as granite and most bluestone handle a firm clean. Layered stones such as slate can lift and flake under a narrow jet. Calcium-based stones such as marble react with acid, so many general outdoor cleaners leave dull etch marks on them. Knowing which one you have decides the whole job.

Crazy paving and mixed stone

Crazy paving often mixes stone types and is set in mortar that's decades old. We clean it at low pressure so the joints stay in place, and tell you about any loose pieces we find.

Nathan just completed a pressure wash of our travertine pavers under our alfresco area, around the pool and the sundeck. What an absolutely fantastic job. Nathan is punctual, knowledgeable, polite and left our place neat and tidy. We will certainly be calling him back on a regular basis and can highly recommend him.

What's the best way to clean bluestone?

A neutral cleaner and a surface cleaner at moderate pressure. Rust and oil marks get a targeted treatment.

Can slate be pressure cleaned?

Gently. High pressure can lift layers of slate, so we keep it low and use brushes on textured faces.

Will cleaning damage marble outdoors?

Not with pH-neutral products. Acidic cleaners etch marble, so we never use them on it.

Do you clean crazy paving?

Yes, at low pressure to protect the old mortar joints.

Should natural stone be sealed?

Often, yes. A breathable penetrating sealer slows staining and mould. We'll recommend one for your stone.

I don't know what stone I have. Can you tell?

Usually, yes. We identify it on site before we quote the method.
