Read some Reviews provided by our satisfied customers

KHPS - Cheltenham

“The old timber windows and doors at Kingston Heath Primary School were severely water-damaged and rotting, posing potential health hazards.

City Aluminium stepped in and custom-made and installed modern, functional, and energy-efficient aluminium doors and windows at a highly competitive price. The quality of their work was outstanding, and the turnaround time—from quoting to installation—was exceptional.

With the new aluminium windows and doors, we’ve eliminated the risk of rot and related health concerns. The school now enjoys a more secure, energy-efficient, and visually appealing environment. We couldn’t be happier with the results!”

“Working with City Aluminium has been fantastic. Their team provided high-quality custom solutions for our bakery, installing sleek, easy-to-maintain commercial aluminum windows and doors.

Not only do they enhance the space’s functionality, but they’ve also created a warm, inviting atmosphere that has improved our street interface. The service was exceptional—prompt, reliable, and professional. Everything was installed on time without disruption to our operations, and their pricing was fair.

We’re thrilled with the results and highly recommend them to any business looking for top-notch service and products.”

Regan Peugeot - Balwyn

“We couldn’t be more pleased with the work City Aluminium did for us. As a car dealership, creating a showroom that is both functional and visually striking is essential, and City Aluminium delivered beyond expectations.

They custom-made and installed large-span aluminium windows and doors that perfectly suit our space, providing clear views of our showroom while allowing natural light to flood the area.

Not only do the new installations create a more inviting and open atmosphere for our customers, but they also enhance the overall aesthetic of the building. The team at City Aluminium was professional, efficient, and attentive to our needs, making the entire process seamless from start to finish.”
