Replacement Double Glazing Quotes in Maidstone
A lot of the double glazing in and around Maidstone went in during the 1980s and 1990s, and plenty of those units and frames are reaching the end of their working life. Whether one pane has fogged or every window in the house is tired, the first question is how much actually needs replacing.
Send a quick description of the glazing and Kent Windows will pass your enquiry to independent installers covering Maidstone, Kent. If suitable firms have space in their diaries, as many as four could offer a survey and quote. There is no charge and no obligation.
Units, Hardware or Full Replacement
If the frame is square and the hinges still work, a new sealed unit may be all a misted pane needs. The fitter unclips the beads, takes out the failed unit and seats a new one cut to the exact size, often in under an hour per window.
Once frames are discoloured, cracked at the welds or out of square, new windows tend to be better value than repeated repairs. A whole-house job also lets you change colour, add easy-clean hinges and fix any rooms that lack a proper escape window.
Signs Your Double Glazing Has Failed
- 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
If just one or two panes are misted, ask about unit replacement before committing to new frames.
A useful first check is whether the moisture wipes off the inner face of the glass. 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.
What to Expect
- First visit: each window is checked to confirm whether the unit, the hardware or the whole frame needs replacing.
- Quote: glass type, frame colour and opening layout are agreed in writing.
- Ordering: sealed units usually take one to two weeks; complete windows take several weeks.
- On the day: units are swapped or old frames removed and new windows fixed, sealed and trimmed.
- Handover: every opener is tested and, for full replacements, the job is registered for a certificate.
Unit swaps are quick and tidy, but full replacement means some dust at the reveals. Agree with the installer how the work will be phased across the house.
Specification Points for Your Maidstone Home
A modern sealed unit should have a low-emissivity coating, argon fill and a warm-edge spacer. 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.
Check how old frames will be removed and disposed of. 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.
Double Glazing Replacement Prices in Maidstone
The guide range for double glazing replacement is £150–£10,500. A single replacement sealed unit sits at the bottom, while a whole-house replacement in coloured frames sits toward the top. Your own figure depends on the survey.
Check whether the price covers VAT, disposal, cills and boards, making good and any scaffolding for upper floors.
What Needs Approval?
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. Check the position for your address with Maidstone 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.

Your Double Glazing Questions Answered
How much does double glazing replacement cost in Maidstone?
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 Maidstone?
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.
