Misty glass does not tell the whole story.
Moisture between the panes is different from condensation on the room-side surface. Tell us where you see it and whether the window still opens and closes normally.
We can discuss failed glazing units, hardware faults and replacement windows. The condition of the frame matters when deciding what work is suitable.
For a first enquiry, photograph the glass in daylight and include the whole frame. Add any other symptoms, such as draughts or trouble locking the window.

Questions from Watford homeowners
Can you change the glass and keep the frame?
That can be an option where the frame is suitable. The glazing type, condition and measurements need checking before a replacement unit is agreed.
Can a faulty window or door be repaired instead?
Sometimes. Failed sealed units, hardware and alignment can differ from a damaged or unsuitable frame; an assessment determines the practical route.
What information helps with a glazing quote?
Provide the location, photographs, approximate dimensions, proposed product and whether the opening already exists.
Can I request installation only in Watford?
Yes, fitting-only can be discussed where customer-supplied products are suitable. Product specification, measurement responsibility and site condition must be confirmed.
Is all condensation a sign of failed double glazing?
No. Moisture on the room-facing surface is different from mist between panes and should be diagnosed separately.
