Five Signs Your Windows Are Costing You Money

Old or poorly sealed windows quietly drain your electricity bill every single day. Here are five signs it's time for an upgrade.

1. Condensation between panes

If you see fog or moisture trapped inside a double-glazed unit, the seal has failed and the insulating gas layer is gone.

2. You can feel a draught with the window shut

Worn gaskets or warped frames let outside air in — and your conditioned air straight out.

3. Street noise feels louder than it used to

Ageing seals and thin single-pane glass lose their acoustic dampening over time.

4. Difficulty opening or locking

Frame movement due to poor installation or material fatigue is a safety issue, not just an inconvenience.

5. Visible frame discolouration or pitting

Powder-coat degradation on aluminium, or yellowing on lower-grade uPVC, is often a sign the profile itself is past its rated life.
