Misted double glazing & condensation between panes fixed in Blisworth
If you're in Blisworth and need misted window repair, you're in the right place. Condensation trapped between the panes means the seal on your double glazed unit has failed. In Blisworth we measure, make and fit a brand-new sealed unit into your existing uPVC, aluminium or timber frame — restoring clear views and insulation for a fraction of the cost of a new window.
- Local engineers in Blisworth
- No call-out fee
- Guaranteed workmanship
Signs your sealed unit has blown
- Room feels colder near the window than it used to
- Mist that comes and goes with the weather and sunlight
- Fog or droplets between the two panes that won't wipe off
- Visible gaps or cracks in the spacer bar around the edge
- White streaks or cloudy staining inside the glass
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 Blisworth
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.
Saturated desiccant
The spacer bar holds crystals that soak up moisture. Once they're full, any air that leaks in leaves condensation you can't wipe away.
Pressure washing and harsh cleaners
Jetting directly at the glass edge or using solvent cleaners on the seals can force water past the gaskets and weaken the bond.

Misted window repair in Blisworth: FAQs
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.
Is the new glass guaranteed?
Yes, every replacement sealed unit comes with our 10-year glass guarantee.
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.
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 Blisworth?
We measure on the first visit and return to fit once the unit is made — usually within one to two weeks.
