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 Norton
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.
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.
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 Norton: FAQs
How quickly can you replace a misted unit in Norton?
We measure on the first visit and return to fit once the unit is made — usually within one to two weeks.
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.
Is the new glass guaranteed?
Yes, every replacement sealed unit comes with our 10-year glass guarantee.
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.
