Misted double glazing & condensation between panes fixed in Delapre

Looking for misted window repair in Delapre? Condensation trapped between the panes means the seal on your double glazed unit has failed. In Delapre 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 Delapre
  • 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
  • Mist that comes and goes with the weather and sunlight
  • Fog or droplets between the two panes that won't wipe off
  • White streaks or cloudy staining inside the glass

How we replace a misted unit

  1. 1. Measure

    We measure the glass precisely and check the frame, beads and drainage.

  2. 2. Manufacture

    Your new unit is made to size — clear, obscure, toughened or A-rated energy glass.

  3. 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 Delapre

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.

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.

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 Delapre: 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.

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.

How quickly can you replace a misted unit in Delapre?

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