Sealed Units
Misted-up double glazing? We replace just the glass, not the frame
Misted-up double glazing? Condensation trapped between the panes means the sealed unit has failed — but it doesn't mean you need new windows. We manufacture replacement double-glazed sealed units to fit your existing frames, whether they're uPVC, aluminium or timber, and fit them across Chichester and West Sussex.
Replacing just the glass costs a fraction of replacing the window, keeps frames that are still perfectly good out of landfill, and upgrades your glazing at the same time: modern soft-coat low-E glass and argon filling make a new unit noticeably warmer than one made twenty years ago.
We measure precisely, make the unit to size, and refit with the correct packers, seals and beads — so the window drains, locks and looks exactly as it should.

Glass technology has moved on: a modern unit with soft-coat low-E glass, argon filling and warm-edge spacers insulates far better than the early double glazing in many local homes. Replacing failed units is one of the cheapest ways to make a noticeable difference to a cold room — without touching the frames.
Engineered to protect
Where regulations require it — glazed doors, side panels and low-level glazing — we make units with toughened or laminated safety glass. Units are refitted with the correct glazing packers and secure beading, so the window is as solid as the day it was made.
Tailored to you
We match what you have — obscure patterns, Georgian bars, leaded designs — or upgrade while we're there: acoustic glass for a road-facing bedroom, solar-control for a hot conservatory, self-cleaning for hard-to-reach panes.
Who this suits
Any home in Chichester, Bognor Regis, Havant or the surrounding area with misted, cracked or draughty double glazing in frames that are otherwise sound — plus landlords and property managers who need units replaced quickly and tidily.
How we do it
We survey and measure each unit, manufacture to size, and refit — typically within days, with each window out of action for well under an hour. No mess, no scaffolding for standard windows, no disruption.
