Condensation on double glazed window pane

How the Repair Works

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

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.

Order the replacement glass

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

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.

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.
