Sealed Unit Replacement
Replacement of failed, misted or cracked double-glazed sealed units while retaining a sound existing frame.
The survey focuses on sealed-unit condition, pane dimensions, spacer details, frame condition and the required replacement specification so the suitable replacement or repair can be agreed.
Sealed Unit Replacement — assessment and replacement plan
What to prepare
Clear photos, approximate pane size, frame material and the fault you can see.
What affects the quotation
Glass specification, unit size, access, processing and installation conditions.
What is checked before sealed unit replacement?
The survey checks sealed-unit condition, pane dimensions, spacer details, frame condition and the required replacement specification so the correct replacement or repair scope can be agreed.
Can just the failed sealed unit be replaced?
Often yes, where the existing frame is sound and suitable for a correctly specified replacement unit.
Can misted glass be repaired without replacing the sealed unit?
Persistent condensation between panes usually indicates a failed sealed unit. The practical remedy is normally replacement of that unit.
Can I improve warmth or noise control at the same time?
Yes, subject to the frame and opening being suitable for the proposed glazing specification.
What information should I prepare?
Clear photos, approximate pane size, frame material and the fault you can see.
What affects the price?
Glass specification, unit size, access, processing and installation conditions affect the quotation.
Do replacement doors or low-level glazing need safety glass?
Safety-glass requirements depend on the location and use of the glazing. The replacement specification should reflect the opening and current requirements.
How quickly can I request help?
The enquiry line is available 24 hours. Attendance, manufacture and fitting times depend on the opening, glass specification and location.
