Misted or Foggy Double-Glazed Windows

If your double-glazed windows have become cloudy, foggy, or show condensation between the panes, this is a sign of a failed window seal. When a seal breaks, moisture gets trapped inside the unit, causing misting and reducing the window’s energy efficiency.

A common question is whether the window can be cleaned or repaired. Unfortunately, once the seal has failed, the only effective solution is to replace the sealed glass unit. The good news is that you usually don’t need a completely new window — just the misted or blown double-glazed unit can be swapped out.

I offer a straightforward service to help with this:

• Inspection of any misted, foggy, or blown double glazing

• Accurate measuring of the failed units

• Supply and installation of new, energy-efficient sealed glass units

• Minimal disruption and a clean, clear finish

Replacing a failed unit restores visibility, improves insulation, and helps keep your home comfortable.
