Can I install aluminium windows myself?

Installing windows, even with lightweight aluminium frames, is very difficult. Glass is heavy and windows are cumbersome to work with.

That’s not to mention the dangers of working at heights. It’s much safer to leave window installation to professionals.

Even if you are proficient in DIY and carpentry, there is a high risk that any windows not properly installed could let in moisture.

This will then lead to dampness and mould. There is also the possibility that the windows could fall out if not safely installed.

For safety and peace of mind, we recommend hiring a professional.
