Questions, answered
Before you book.
Why publish one price when nobody else does?
Because we can. Sealing is one thing done to a certified standard, so it prices cleanly by area: $16/m², all-in. Hiding the price is how the category protects its margins; publishing it is how we earn your trust before we've met.
What's included in the $16/m²?
Everything: the full professional preparation clean of the surfaces being sealed, MineralProtect applied by our certified applicators, and registration of your guarantee. The clean is never itemised or sold on its own.
Will sealing stop my driveway getting dirty or stained?
No coating stops dirt or staining. What sealing changes is how the surface behaves: it repels water and oil, resists oil and grease staining, sheds dirt and adds UV protection, so build-up is slower and washes off more easily. You still clean it occasionally. It's just far easier to keep looking right.
How long does the seal last?
Two things, kept separate on purpose. We recommend a top-up roughly every one to three years for stone and concrete, and every two to five years for glass, to keep the seal performing at full strength — re-treatment restores it, we track when yours is due, and every surface differs. The guarantee runs for 10 years, covering the sealed system performing as described. For glass, GlassProtect makes water bead and sheet off, so rain and a quick rinse do most of the cleaning and the glass largely keeps itself clean through the wet winter months. It is tested 3× more durable than the leading brand and protects glass against permanent etching. Your guarantee sits on top of your Australian Consumer Law rights.
Does sealed glass still need any upkeep?
The hard part is done. GlassProtect makes water bead up and sheet straight off, so rain and the occasional rinse carry most of the dirt away and the glass largely keeps itself clean, hands-off through the filthy winter months. When you do want it clear, a quick wipe or squeegee is easy work rather than a scrubbing job, because far less grime clings to a coated surface in the first place. It also protects glass against permanent etching, the kind that dulls bare glass for good. Your glass still gets the occasional clean, it is just far less of your time.
What about weather and curing?
The surface needs to be dry to seal and to cure without interruption, so we schedule around Perth weather and confirm the dry window with you before the visit. The seal is dry to handle within hours and fully cured in about a day.
Is it safe? Anything I should know about the products?
JUMBOGUARD coatings are professional-grade and applied by certified applicators to spec. MineralProtect is water-based, and both coatings are PFAS-free by composition (no forever-chemicals) and REACH-compliant. The cured film is inert. Full safety data sheets are available on request.
Why seal instead of just re-cleaning every year?
A clean removes the build-up but leaves the surface unprotected, so it goes straight back to soaking up water and staining. Sealing changes how the surface handles water and dirt, so it's easier to maintain between cleans, and the result is registered under the guarantee. It's protection, not a repeat service.
Is there a reward for rebooking or referring?
Yes. It's called Extera Protected. When your reseal is due, members take up to $400 off the next clean & seal. And refer a neighbour or a friend: you both get $200, and it stacks, so every referral is another $200 toward your next job. See Extera Protected
