Triple glazed sealed unit replacement in Gravesend
From the first measure to the handover pack, we handle triple glazed replacement sealed units for homes in Gravesend and the rest of Kent.
Straight advice on swapping glass only, and when it is worth it. Sealed unit replacement means changing only the glass in an existing frame.
Winter light and glass choice in Gravesend
Winter days in Gravesend are short: about 7 h 50 min of daylight on 21 December, with the sun peaking near 15°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

Rules for glass-only replacement in England
England requires replacement windows to achieve 1.4 W/m²K, or a Window Energy Rating of band B or better, which good triple glazing passes comfortably. Replacement windows are a controlled fitting. A competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council within 30 days; otherwise a building control body approves it.
Before ordering: Replacing windows on a house is normally permitted development if the new ones look similar. New upper-floor windows in a side wall must be obscure glazed and fixed, or open only above 1.7 m. Flats and maisonettes have no householder permitted development rights, so a change that alters their appearance needs planning permission. An Article 4 direction in a conservation area may mean permission is needed, and listed buildings need listed building consent.

Questions from Gravesend
Can I put triple glazing in my existing windows?
Usually not in a way that helps. Most frames take up to about 28 mm units; a triple unit that thin performs about the same as, or worse than, good double glazing. We check your frames before recommending anything.
Why are my windows misting between the panes?
The seal around the unit has failed and moist air has got in. Only replacing the unit fixes it.

Yes. We arrange surveys and fitting in Gravesend and across Kent. Send your postcode and the windows or doors you want replaced, and we will book a free survey.
How long does it take to get triple glazed replacement sealed units fitted in Gravesend?
