How the Repair Works

Replacing a failed double glazed unit is straightforward — here's the process:

1

We assess the unit

We visit your home (free of charge) and confirm the sealed unit has failed. We measure the glass and check the frame condition.

2

Order the replacement glass

We source the exact specification double glazed unit — matching the thickness, coating, and gas fill of your originals.

3

Install the new unit

We remove the failed glass, fit the new sealed unit into your existing frame, and reseal. Most replacements take under an hour per unit.

4

Enjoy clear windows again

No more condensation, better insulation, and a crystal-clear view — all at a fraction of the cost of new windows.

Why Repair Instead of Replace?

Save Up to 70%

A glass-only replacement costs a fraction of a full window. Keep your frames and just swap the failed unit.

Improve Energy Efficiency

A failed unit loses its insulating gas fill. Replacing it restores thermal performance and reduces bills.

Eliminate Condensation

No more misted-up windows. The new sealed unit keeps moisture out permanently.

Maintain Your Home's Look

Your window frames stay the same — no mismatched styles, no decorating, no disruption.
