Commercial buildings in the Auckland C*D take more of a beating than most.

Sitting between two harbours, they’re hit by salt-laden winds, strong UV, humidity and daily temperature shifts. Salt builds up around joins and edges, UV breaks down the coating’s binder, moisture creeps into weak spots, and constant expansion and contraction leads to micro-cracks. Over time, even high-quality factory powder coatings start to fail.

We refinish previously powder-coated façades and joinery on-site with wet-spray architectural coatings, restoring colour and protection without removing panels.

Refurbishment isn't just cosmetic.

While it improves how your joinery looks, it also brings major benefits to its performance and longevity. It's a proactive maintenance strategy that protects your investment.

Some of these photos feature original aluminium joinery that we’ve professionally refinished. The rest are brand-new.

Not every quality finish needs to start from scratch.

With the right preparation, products, and application, existing aluminium joinery can be transformed and given a new lease on life.

Aluminium facades, joinery and cladding don't always need replacing. Often they can be repaired, resprayed or refurbished for a fraction of the cost.

For property owners and building managers, we offer powder-coat repairs, full facade recolours, ACM/ACP refurbishment, custom paint matching and a range of durable finishes, all designed to get more life out of what's already there.

How long does powder coating really last in NZ conditions?

Powder coating is durable, but in New Zealand, lifespan comes down to exposure. A building in Mission Bay ages very differently to one in Penrose.

Salt, UV, wind and moisture all wear at the coating over time. Inland surfaces can hold up for 15 to 25 years or more, while high-salt waterfront and high-rise sites often show breakdown in under 10 to 12.

We restore aluminium that was previously powder coated with advanced wet spray systems, bringing back protection when the original finish starts to fail.

A great piece of feedback from CMP’s Mark Crene for our aluminium joinery remediation work at Alexandra Park.

It’s great to have both the finished result and the team’s effort recognised.

Read his full testimonial below.

“Thanks very much for the great job you and your team have done here at Alexandra Park Building A, remediating all the aluminium joinery. The Matte Black aluminium joinery has come up looking fantastic thanks to your high-quality workmanship.

We appreciate the huge logistical effort it has taken to complete all the work in such a demanding timeframe, including your whole team working some big weekends.”

What happens when moisture gets behind a facade coating?

A facade coating does more than improve how a building looks. It protects the aluminium joinery, steel and architectural panels underneath from weather and everyday exposure.

When moisture gets behind that coating, the surface can start to deteriorate from the inside out. The first sign is often small: a bubble, a peeling edge, a patch of discolouration. Beneath the surface though, moisture may already be weakening adhesion or starting corrosion.

Painting over it rarely holds. A fresh layer can hide the problem for a while, but it doesn't restore the failed bond underneath, so the blistering tends to return.

Caught early, it can be the difference between a localised repair and a full facade refurbishment.

Can aluminium joinery be refinished while a building is still occupied?

In most cases, yes.

Our on-site refinishing process is staged in sections, with access coordinated around tenants and building operations to help minimise disruption.

Before work begins, we inspect the joinery to confirm refinishing is the right option. From there, the process includes:

→ Preparing the existing aluminium surface
→ Repairing worn or corroded areas
→ Masking the glazing and surrounding finishes
→ Applying the new coating by spray
→ Completing a final quality check

For aluminium joinery that is fading, chalking or showing signs of age, refinishing it in place can be a more practical and cost-effective option than full replacement.

The longer you wait on facade maintenance, the more expensive your options get.

Aluminium joinery, powder-coated finishes and facade panels fade, chalk and corrode slowly, so nothing looks urgent until suddenly it does.

And that slow decline is the trap.

A surface you could have refinished this year, quietly crosses the line to full replacement.

And replacement costs more, disrupts more and wastes more.

Reactive maintenance means paying for that on someone else's timeline: urgent access, rushed budgets, tenants dealing with the fallout.

Planned maintenance means you catch surfaces while they're still restorable, stage the work around how the building runs, and control what it costs.

The building isn't going to tell you when it's time.

By the time it looks like it needs the work, the cheapest fix is already behind you.

We'd rather assess a facade while restoring it is still on the table.

Get in touch on 0508 732 656 or [email protected] before that choice gets made for you.
