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.
What causes the problem — common faults we see in Billing
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.
Poor original fitting
Units fitted without proper packers can sit on the frame unevenly, putting pressure on one corner and splitting the seal early.
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.

Misted window repair in Billing: FAQs
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.
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.
How quickly can you replace a misted unit in Billing?
We measure on the first visit and return to fit once the unit is made — usually within one to two weeks.
