Double Glazing Replacement in Cranbrook
Much of the glazing on Cranbrook homes dates from the first big wave of uPVC in the 1980s and 1990s, and many of those sealed units have now given up. From a single misted unit to a whole house of old frames, the right answer depends on what has failed.

Glass Only or the Whole Window?
A fogged pane in a sound frame can usually be fixed by swapping just the glass unit. Once the glazing beads are unclipped, the fogged unit is lifted out and a made-to-measure replacement set in its place, usually within an hour or so once the unit has been made.
Where frames have yellowed, the corners have cracked or several openers have dropped, full replacement often makes more sense. Replacing everything at once means a consistent look and specification throughout the house.
Common Glazing Faults in Cranbrook Homes
- Moisture or white staining inside the sealed unit
- Gaskets that have shrunk or perished, letting rain behind the glass
- Frames that have yellowed or cracked at the welded corners
- Openers that drag on the frame or will not lock
- Cold spots near large panes of early, uncoated glass
Mention which windows are fogged and which are simply old, so the survey can separate the two.
Ask the surveyor to distinguish a failed glass seal from condensation on the room side. If only the sealed unit has failed, a fitter can measure the glass thickness and spacer before ordering a replacement, while retaining a sound frame and working hardware.
How Replacement Works
- Assessment: each window is checked to confirm whether the unit, the hardware or the whole frame needs replacing.
- Agreeing the details: glass type, frame colour and opening layout are agreed in writing.
- Manufacture: sealed units usually take one to two weeks; complete windows take several weeks.
- Installation: units are swapped or old frames removed and new windows fixed, sealed and trimmed.
- Sign-off: every opener is tested and, for full replacements, the job is registered for a certificate.
Full window replacement disturbs the plaster around each opening, so ask what making good includes. Ask how many windows will be done each day and whether every room will be secure overnight.
Details Worth Agreeing Up Front
Ask each firm what coating, gas fill and spacer bar the new units will have. For full replacements, get a whole-window energy rating rather than a figure for the glass alone, and check that bathroom and low-level panes will have the right obscure or safety glass.
Ask whether disposal, new cills and new window boards are in the price. If you are near a busy road or railway, ask for acoustic laminated glass to be priced as an option, and confirm how trickle vents will keep rooms ventilated once the draughts have gone.
Budgeting for New Double Glazing
The guide range for double glazing replacement is £150–£10,500. The lower end reflects one misted unit swapped in a sound frame, while renewing every window in a typical house sits toward the top. Large houses and bespoke frames can exceed the range, so treat it as a starting budget.
Make sure each quote says whether it includes VAT, disposal, cills and boards, making good and any scaffolding for upper floors.
Planning and Building Regulations
Like-for-like replacement windows on a house are usually permitted development. Listed buildings, flats and streets covered by an Article 4 direction are the main exceptions, and changing material or style there may need consent. If you are unsure, speak to Tunbridge Wells Borough Council.
Replacing only the sealed unit is a repair and does not need Building Regulations sign-off. Replacing the whole window does, and an installer registered with a competent person scheme can self-certify it; see the government's competent person scheme guidance.

Common Questions About Replacement Double Glazing
How much does double glazing replacement cost in Cranbrook?
The guide range is £150–£10,500, from one replacement sealed unit to renewing every window in a typical house. Coloured frames, large houses and specialist glass can push the cost higher.
Can misted double glazing be fixed without new frames?
Usually. If the frame and hinges are sound, a new sealed unit can be made to size and fitted into the existing frame, which is far cheaper than a new window.
Do I need a certificate for replacement windows in Cranbrook?
For a whole new window, yes. A competent person scheme installer can register the job and issue a certificate. Replacing only the glass unit is a repair and does not need one.
How long does it take to replace double glazing?
A sealed unit can be swapped in about an hour. Replacing every window in a typical house usually takes one to three days once the frames have been made.
