Limescale gone, the stone intact

Fixed price Test patch first 📸 Before & after photos

On the coast the buildup comes from outside. Salt in the air settles on glass and metal, wind blows sand against the facade, and north-facing terraces turn green. That's a different problem from limescale out of the tap, and it needs a different treatment.

Why Kust Cleaning

How we work

Salt isn't limescale

Sea buildup needs a different treatment from tap-water scale. We check which one it is first.

Careful with balustrades

Stainless and coated metal by the sea are vulnerable. Abrading makes corrosion worse, not better.

Test patch first

On an inconspicuous spot, so you judge the result before we continue.

Protective layer that slows buildup

By the sea that's no luxury: without aftercare it returns faster than inland.

How it works

Here's how it goes

A photo of the buildup is often enough for a first estimate.

1

Send a photo

It tells us whether it's salt, green growth or limescale.

2

Test patch on site

We treat a small area, you judge the result, then we set a fixed price.

3

Treatment and protection

Usually one day for a terrace or bathroom, including dwell time.

FAQ

Natural stone & limescale — your questions answered

What's the difference between salt film and limescale?

Limescale comes from your tap water and sits indoors, on taps and shower screens. Salt comes from the sea air and settles outdoors on windows, balustrades and facade stone. They respond to different products, so one product for both rarely works.

My terrace balustrade is corroding. Can you deal with that?

We can remove the buildup and early corrosion, but we don't abrade. By the sea, abrading opens the protective layer of stainless or coating, after which corrosion returns faster than before. For deep rust we'll refer you to a metal specialist.

My terrace goes green every year. Why does it return?

Green growth is organic and thrives where it's damp and shaded, which on the coast is most of the year. Washing it off removes the layer but not the spores; we treat it so it dies off and finish with a layer that slows regrowth.

How often is this needed on the coast?

More often than inland. For terraces, annually in spring is typical; for sea-view windows it depends how close to the seafront you are.

What if the test patch disappoints?

Then we stop and you pay nothing for the test. On glass worked with abrasive cleaner for years the result is sometimes limited, and we say so in advance.

Do you clean full facades?

Thresholds, plinths, balustrades and defined areas, yes. A full facade requiring scaffolding is outside our offer.

Natural stone and limescale removal in Ostend

On the Belgian coast, buildup on stone and glass mostly comes from outside. Sea air carries salt that settles on windows, stainless balustrades and facade stone, and the damp climate turns north-facing terraces and garden paths green. Kust Cleaning treats both, from Middelkerke to Knokke-Heist.

Salt behaves differently from limescale. Limescale is a mineral deposit from tap water and sits indoors, on taps and shower screens. Salt film comes from the air, attacks metal, and hazes glass in a way ordinary glass cleaner won't shift. Each needs a different product, and with balustrades it also calls for restraint: abrading opens the protective layer of stainless and coatings, so corrosion returns faster.
