Sealing in Denmark.
We seal and protect natural stone, concrete and glass across Denmark and the surrounding suburbs, matched to how your local water runs. One published price, a full preparation clean included, and a 10-year guarantee registered to your job.
Why it matters here
Denmark's water is hard on surfaces.
Denmark's water runs hard, high in dissolved minerals off the south coast. That hardness leaves scale and mineral build-up on stone, concrete and pool surrounds, and spotting on glass that etches bare glass for good. Sealing changes how the water behaves, so scale and spotting wipe away instead of bonding on.

What we seal in Denmark
The right coating for each surface.
Porous stone and concrete get a mineral seal that engineers the surface itself; non-porous glass gets a different chemistry. We match the surface to the coating, and stand behind the result for 10 years.
Driveways & concrete
Exposed aggregate, liquid limestone and plain concrete, sealed colourless and breathable so it repels water and resists oil, with no film to peel.
How we seal concrete
Natural stone & pavers
Limestone, travertine, granite, benchtops and cladding, protected against salt, scale and staining with no residue and no colour change.
How we seal stone
Glass & balustrades
3× more durable than the leading brand. Protects glass against the permanent etching that hard water causes, so spots wipe away instead of bonding on.

Common questions
Your questions, answered.
Do you seal in Denmark?
Yes. Extera seals driveways and concrete, natural stone and pavers, and glass across Denmark and the surrounding area, including Albany, Walpole and Peaceful Bay. Tell us your suburb when you get a quote and we'll confirm we're out your way.
How does Denmark's water affect my stone and glass?
Denmark's water runs hard, high in dissolved minerals off the south coast. Hard water leaves scale on stone, concrete and pool surrounds, and spotting on glass that etches bare glass over time. Sealing lets scale and spotting wipe away instead of bonding on.
What does sealing cost in Denmark?
One published rate: $16/m² all-in for stone and concrete, minimum job $950, which includes the full preparation clean, the matched coating and your guarantee registration. Glass is priced separately, from $8/m², minimum job $480. We confirm the fixed price before you book.
How long does the seal last?
We recommend a top-up roughly every one to three years to keep the seal at full strength, sooner where it is used hard or takes a lot of sun, longer where it is sheltered, and every surface differs. The guarantee runs for 10 years, covering the sealed system performing as described.
