Built to solve a problem others could not

Protect Shield began when a commercial client asked a simple question: could faded aluminium window frames be restored properly without the cost and disruption of replacement?

At the time, no one had a practical answer. Major paint brands said it could not be done cost-effectively. With more than 20 years in the window industry, Brett Horton was not prepared to accept that.

After extensive research, Brett discovered a proven Australian restoration system originally developed to restore powder-coated surfaces in harsh environments. Recognising its potential for New Zealand homes and buildings, Protect Shield secured exclusive rights to bring the system here.

Today, Protect Shield provides a practical, affordable alternative to replacing
faded aluminium joinery, restoring window frames, doors, garage doors and exterior aluminium surfaces at a fraction of replacement cost.

Experience, innovation, and practical advice

Protect Shield is led by Brett Horton, whose decades in the window and glazing industry have given him firsthand insight into the challenges homeowners and property managers face with ageing aluminium joinery.

This is not a cosmetic quick fix or a repainting service. Protect Shield uses a proven five-step restoration process that removes oxidation, treats the surface, and applies durable UV-stable protective coatings designed for long-term performance.

Clients value straightforward advice, fixed pricing, and honest recommendations about whether restoration is the right option for their property. In many cases, aluminium restoration delivers a dramatic improvement without the disruption, waste, or cost of full replacement.
