Replacing Old Double Glazing in Whiteley
Cloudiness inside a sealed glass unit is different from moisture on the room-facing surface. For a Whiteley property, the frame condition helps decide how much work is worthwhile.
Send a short note on the state of your double glazing and Hampshire Windows can pass your enquiry to independent installers covering Whiteley, Hampshire. Installers with space in their diary, up to four of them, may then offer a quote, with no charge and no obligation.
New Glass or New Windows?
If the frames are square and the hinges and locks still work, replacing only the failed sealed units can be a sensible, lower-cost fix. Replacement units can also be better than the originals, with low-emissivity coatings, gas fills and warm-edge spacers, or with laminated or acoustic glass.
When the frames themselves are failing, putting new glass into them rarely pays off. Ask each installer to explain which option they recommend and why, because firms that only fit whole windows and those that only replace glass may give different advice.
Common Problems with Older Double Glazing
- Condensation or a milky film trapped between the panes
- Cracked glass in an otherwise sound frame
- Old aluminium frames with no thermal break that run with condensation
- Early uPVC frames with split welds, perished seals or obsolete locks
- Low-level or door glass that is not marked as safety glass
Note which windows are affected and roughly how big each pane is, and whether any are in doors or near the floor.
Details to Settle at the Survey
Ask the glazier to record unit thickness as well as height and width. Upgraded coatings or acoustic glass are only useful where the existing frame can safely accommodate the proposed unit.
From Assessment to Handover
- Assessment: the installer checks whether the frames are worth keeping and measures the glass or the whole openings.
- Manufacture: sealed units are made to exact sizes, often within a week or two.
- Glass-only work: beads are removed, the old unit lifted out and the new one packed and re-beaded, usually well under an hour each.
- Full replacement: old frames are removed and new windows fixed, glazed and sealed, usually several per day.
- Final checks: the installer checks every sash, removes old glass and frames, and supplies any certificate needed.
During a glass-only repair, the glazier should check packers, gaskets and drainage. The new unit must be supported and re-beaded correctly. Old glass should be removed from the property safely as part of the agreed job.
Tell firms whether the failed glass in Whiteley is in a door, bathroom or upper-floor window. Safety glass, obscure finishes and difficult access can change the price.
Double Glazing Replacement Costs in Whiteley
The guide range for this service is £150–£11,000. A single replacement glass unit sits at the very bottom of that range, while a whole house of new windows sits at the top. Where your job sits depends on how much needs replacing.
For glass units, the price depends on size, glass type and access. For full replacements, confirm whether the price covers VAT, removal of old frames, new cills and boards, and making good.
What Needs Approval
Swapping only the glass in an existing frame is generally treated as a repair, so it does not normally need planning permission or a Building Regulations certificate. Replacing whole windows is controlled work, and the new windows must meet current energy efficiency standards; an installer registered with FENSA, Certass or a similar scheme can self-certify it.
New windows on a house are normally permitted development if they look similar to the old ones, but flats, listed buildings and conservation areas may need consent. If you are unsure, check with Winchester City Council. The Planning Portal explains the Building Regulations requirements for windows.

Your Questions Answered
The answers below address points worth raising before a survey in Whiteley.
How much does double glazing replacement cost in Whiteley?
The guide range is £150–£11,000. A single replacement sealed unit is at the lower end, and a whole house of new windows is at the upper end. These are indicative project budgets, not fixed prices or a maximum charge.
Can I replace only the misted glass in my windows?
Yes, if the frames are in good condition. New sealed units can be made to fit existing frames. Warped frames may justify replacement, while worn locks or hinges may be repairable separately.
Do new glass units need a FENSA certificate?
Replacing only the glass is generally treated as a repair and does not normally need a certificate. Replacing whole windows, including the frames, does need to be certified or approved.
How many quotes can I get for double glazing replacement in Whiteley?
Up to four installers covering Whiteley may reply, whether you need a single glass unit or a full set of windows. You are free to decline all of them.
Will replacement glass cure condensation on the inside?
Not necessarily. Moisture on the room-facing surface can relate to indoor humidity, ventilation and surface temperature. Misting trapped between the panes points to a sealed-unit problem and needs a different assessment.
