Sealing in Kojonup.
We seal and protect natural stone, concrete and glass across Kojonup 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
Soft water, not off the hook.
Kojonup's water runs soft, on the Albany Highway, so hard-water scale is less of a worry here than inland. But soft water is only half the story: sun, salt, oil and foot traffic still stain and wear bare stone and concrete. Sealing protects against those, and keeps the surface easy to clean and quick to wipe down.

What we seal in Kojonup
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.

How does Kojonup's water affect my stone and glass?
Kojonup's water is soft, so scale is less of an issue than inland. Sealing still pays: it protects bare stone and concrete from sun, salt, oil and traffic staining, and keeps the surface easy to clean.
What does sealing cost in Kojonup?
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.
