- Local engineers in Isham
- No call-out fee
- Guaranteed workmanship
Signs your sealed unit has blown
- Fog or droplets between the two panes that won't wipe off

- Mist that comes and goes with the weather and sunlight
How we replace a misted unit
1. Measure
We measure the glass precisely and check the frame, beads and drainage.
2. Manufacture
Your new unit is made to size — clear, obscure, toughened or A-rated energy glass.
3. Fit
The old unit comes out, the new one goes in and the beads are refitted. Usually under an hour per window.
Replacing only the glass unit keeps your frames, avoids building work and typically costs far less than a whole new window.
Why misted window repair problems happen in Isham
Age of the seal
Sealed units are bonded with a perimeter sealant that slowly breaks down. After 10–20 years many units start letting moist air in between the panes.
Sun and temperature swings
South and west-facing glass heats and cools every day. That constant expansion and contraction stresses the edge seal until it fails.
Poor original fitting
Units fitted without proper packers can sit on the frame unevenly, putting pressure on one corner and splitting the seal early.

Misted window repair in Isham: FAQs
Can misted double glazing be fixed without replacing the window?
Yes. We swap just the sealed glass unit and reuse your existing frame, so there is no mess and no planning needed.
Why is there condensation inside my double glazing?
Condensation between the panes means the unit's seal has failed and moist air has got in. It can't be wiped away — the sealed unit needs replacing.
Can I upgrade the glass at the same time?
Absolutely — choose obscure privacy glass, toughened safety glass or higher energy-rated glass.
How quickly can you replace a misted unit in Isham?
We measure on the first visit and return to fit once the unit is made — usually within one to two weeks.
Is the new glass guaranteed?
Yes, every replacement sealed unit comes with our 10-year glass guarantee.
