Signs your sealed unit has blown

Room feels colder near the window than it used to
White streaks or cloudy staining inside the glass
Visible gaps or cracks in the spacer bar around the edge
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 it breaks: what our engineers find in Northampton

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.

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.

Misted window repair in Northampton: 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.

How quickly can you replace a misted unit in Northampton?

We measure on the first visit and return to fit once the unit is made — usually within one to two weeks.

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.

Is the new glass guaranteed?

Yes, every replacement sealed unit comes with our 10-year glass guarantee.
