Capability statement · For builders, commercial & strata

Clean it. Seal it. Keep it.

Extera cleans, restores and seals the exterior surfaces of Western Australian buildings. Three stages in the life of every surface, done by one supplier to one standard, so the result holds instead of coming back on a yearly cycle.

Three pages. What we do, why the sequence matters, and everything a site office or a committee needs to open an order.

Clean it. Seal it. Keep it.

Three stages in the life of every exterior surface. Most buildings hire a different contractor for each one and pay for the gaps in between. Extera does all three, in order, under one certificate of currency.

The problem with a wash on its own

A clean is a date, not a fix

Washing removes what is sitting on the surface. It does not change what the surface does next, so the same growth, staining and weathering come back on the same cycle and the work goes out to tender again every year or two. The asset never actually gets ahead, it just gets reset.

What we do instead

Clean it, restore what's damaged, then seal it

The clean is preparation. Damage a clean cannot touch, etched and corroded glazing, scratched panels, staining welded into masonry, gets restored mechanically. Then the surface is sealed so it sheds water instead of drinking it, and the next clean is easier and further away.

What one visit changes

A rendered elevation, soft washed. Same angle, same day.

Rendered elevation darkened by organic growth and weathering before cleaningBefore
Growth, not dirt. Render holds moisture, and on a shaded elevation that becomes the black and green film that makes a building read as tired years before it is.
The same rendered elevation after a soft wash matched to the substrateAfter
Soft washed, not blasted. A biodegradable biocide at a dilution matched to the substrate, applied at low pressure and given time to work. The solution does the job, not force, so the render, the seals and the paint finish are untouched.

Three stages, one supplier

Each stage stands on its own, and you can buy any one of them. They are worth more in order.

01

Cleaning

Roof cleaning and treatment, soft washing, building and facade wash, driveway and hard surface cleaning. Delicate surfaces are soft washed: a biodegradable biocide at the right dilution, applied at low pressure, so the solution does the work and not force.

Restoration

Glass restoration and scratch removal, and mineral staining that has bonded into masonry. Western Australia's only dedicated glass restoration specialists. Worked in situ, so nothing is removed and nothing is replaced.

Sealing & protection

MineralProtect on stone and concrete, GlassProtect on glass. Water-based, breathable and film-free, optically invisible, no colour change to either, and registered under a guarantee of up to 10 years.

Why the sequence matters

One supplier, one certificate of currency, one line of accountability.

When the wash, the restoration and the seal are three different contractors, the gaps between them are yours to manage: three inductions, three sets of site documents, three certificates of currency to chase, and an argument about who caused what the day something goes wrong.

It also fixes the order of operations. Sealing a surface that was not properly prepared locks the problem underneath it. Cleaning a surface and leaving it bare starts the same clock again the day we drive away. Done in sequence by one crew, the surface gets ahead and stays there, and the building is accessed once instead of three times.

The guarantee

Registered to the address, not a promise on a quote

Every seal is registered under the JUMBOGUARD Performance Guarantee: issued by JUMBOGUARD, applied to a certified standard, recorded against the address in plain language and running up to 10 years. It sits on top of Australian Consumer Law rights, never instead of them.

And what it doesn't cover

The sealing, and we say so out loud

The guarantee covers the seal. Cleaning is quoted and done on its own merits, and if a surface only needs a clean, that is what you will be told. We would rather lose the sealing line than register a guarantee over work that did not need doing.

Assessed before quoted. Substrate decides the method, and a surface that only needs a clean gets told that. Cracked or structurally failed material is a replacement, not a restoration, and you will hear that first.

How we engage

  1. Site assessment.We look at the actual surfaces, identify the substrate and what is on it, and separate what needs cleaning from what needs restoring and what is worth sealing.
  2. Scope and confirmed price.Published rates where there is a rate, quoted per job where damage decides the work. The price is confirmed before anything is booked.
  3. Programmed works.Sequenced so the clean, any restoration and the seal happen in the right order and the building is accessed once rather than three times.
  4. Registration and sign-off.Sealed work is registered under the JUMBOGUARD Performance Guarantee against the address, and the certificate comes to you.

Defect, insurance and contra works. Damage on a new build is usually a matter between the builder, a subcontractor or the insurer before it is a matter of the surface. We assess and quote in terms all three can act on, and we say plainly what is restorable and what is not.

What we need to quote. The site address and how to get on it, what the surfaces are if you know, photos taken at a raking angle where glass or polished stone is involved, any dates we have to work around, and any induction or permit requirements so site documents reach you before we arrive.
