Misted double glazing & condensation between panes fixed in Irthlingborough
If you're in Irthlingborough 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 Irthlingborough 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 Irthlingborough
- No call-out fee
- Guaranteed workmanship
Signs your sealed unit has blown
- Room feels colder near the window than it used to
- Visible gaps or cracks in the spacer bar around the edge
- Fog or droplets between the two panes that won't wipe off
- White streaks or cloudy staining inside the glass
- 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.
The real causes behind misted window repair jobs in Irthlingborough
Blocked frame drainage
If the drainage slots under the glass get blocked, rainwater sits against the bottom edge of the unit and attacks the seal from below.
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.
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.

Misted window repair in Irthlingborough: 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.
Can I upgrade the glass at the same time?
Absolutely — choose obscure privacy glass, toughened safety glass or higher energy-rated glass.
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.
How quickly can you replace a misted unit in Irthlingborough?
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.
