Replacing Old Double Glazing in Fareham
Before replacing double glazing, establish whether misting is between the panes or on the surface. An assessment in Fareham can separate a glass-only repair from a complete window replacement.
Send a short note on the state of your double glazing and Hampshire Windows can pass your enquiry to independent installers covering Fareham, 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?
Where the frames are sound and only the glass has failed, new sealed units may be all you need. 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.
If the frames have warped, the welds have split or parts are no longer available, new windows are usually better value. A good installer will explain why they favour one approach over the other, 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
Counting the affected panes and noting their sizes helps the first conversation, and whether any are in doors or near the floor.
Details to Settle at the Survey
The replacement sealed unit must match the available glazing rebate and beads. 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: new windows are made to measure, which takes a few weeks.
- 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.
Replacing a sealed unit also gives the glazier a chance to inspect the glazing seals and drainage paths. 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.

Double Glazing Replacement Costs in Fareham
The guide range for this service is £150–£11,000. The range runs from swapping one sealed unit to renewing every window in the house. Most jobs fall somewhere in between.
Sealed unit prices vary with size, glass specification and how easy the window is to reach. For whole windows, check whether each quote includes 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 Fareham Borough Council. The Planning Portal explains the Building Regulations requirements for windows.

For eligible replacement work, confirm the installer’s scheme registration and certification arrangements.

Your Questions Answered
The answers below address points worth raising before a survey in Fareham.
How much does double glazing replacement cost in Fareham?
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 Fareham?
Up to four installers covering Fareham 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.
