About Extera
One thing, done at a certified standard.
Extera is Perth's sealing specialist. We don't do a bit of everything. We seal and protect natural stone, concrete and glass, inside and out, to a certified standard, at one published price. The surface clean is included as preparation; it's never a service on its own.
Why a specialist
Cleaners clean. We seal.
Most operators sell the clean and treat the seal as an add-on. Extera exists to do the sealing properly. It's a certified craft: the right coating, the right preparation, applied to spec and registered under guarantee.
That standard is the point. It's what makes Extera a JUMBOGUARD Certified Applicator, why the guarantee runs through certified applicators, why we can publish one price, and why we can stand behind every surface we seal.
