🧽 Natural Stone & Limescale Removal

Limescale on natural stone? We remove it without damaging the stone.

In Kortrijk the problem is usually outdoors: green growth on north-facing terraces, moss between the paving and weathered thresholds. We deal with it without opening up the stone, always after a test patch.

Limescale gone, the stone intact

Fixed price Test patch first 📸 Photos on request

The damp Leie climate means terraces and driveways in Kortrijk turn green faster than they build up limescale. That needs a different approach from descaling: green growth is an organic layer you have to kill and remove, not dissolve with acid.

Why Jans Cleaning

How we work

Green growth, not just limescale

Two different problems with two different treatments. We check which one is yours first.

No pressure washing on weathered stone

The jet opens the top layer and then it returns faster than before.

Test patch first

Somewhere nobody sees. You assess the result before we continue.

Treatment that lasts

A finish that slows moss and growth returning, rather than reappearing by autumn.

How it works

Here's how it goes

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

1

Photo of the surface

That usually tells us whether it's green growth, limescale or cement haze.

2

Test patch on site

We treat a small area, you assess it, then we agree a fixed price.

3

Treatment and protection

So you get more than a single season out of it.

FAQ

Natural stone & limescale — your questions answered

My terrace goes green every year. Why does it come back?

Green growth is an organic layer that thrives where it's damp and shaded. Washing it off removes the layer but not the spores, so it's back by autumn. We treat it so it dies off, then apply a finish that slows regrowth.

Can't I just use a pressure washer?

You can, but on weathered paving or old bluestone the jet opens up the top layer. It looks good for a week and then attracts dirt faster than before. On solid, recent paving it's less of an issue.

What's the difference between green growth and limescale?

Green growth is organic and mostly outdoors on north-facing surfaces. Limescale is mineral deposit from hard water and mostly indoors, in showers and on taps. Each needs a different product.

What if the test patch disappoints?

Then we stop and you pay nothing for the test. We'll say honestly whether it's achievable before agreeing a price.

How long does a terrace or driveway take?

A typical terrace is one day including dwell time. A larger driveway we plan over two.

Do you clean full facades?

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

Natural stone and limescale removal in Kortrijk

In Kortrijk and the Leie region, green growth is a bigger problem than limescale on stone. The damp climate and the many north-facing terraces and driveways mean moss and algae establish quickly, especially on paving and concrete slabs that don't get full sun.

That calls for a different treatment from descaling. Green growth is organic: it has to be killed off and removed, not dissolved with an acidic product. And pressure washing looks like the fastest route, but on weathered paving and old bluestone the jet opens the top layer, so it returns faster afterwards.
