How long does aluminium window replacement take?
Most replacements take about 1–2 days per room, including setup, installation, and cleanup. Larger projects or custom designs may take slightly longer.

Can I replace just the glass in aluminium windows?
Yes, you can. Aluminium window glass replacement is a practical option if the frames are still strong. It allows you to update glazing for better insulation or privacy without replacing the entire unit.

What’s the lifespan of aluminium replacement windows?
High-quality aluminium windows typically last 20–30 years, depending on exposure to weather and level of maintenance.

Do you do repair glazing?
No, we do not do repair glazing of broken glass due to breakages or theft. We can fully replace the glass panel, though.

Is aluminium eco-friendly?
Yes. Aluminium is 100% recyclable, and when combined with energy-efficient glass, it helps reduce heating and cooling costs.
