Double Glazing in Fareham & Hampshire
Every window we make is double glazed as standard, with sealed units chosen to hold heat in through a Solent winter and keep road noise out. If your existing double glazing has misted, blown or stopped closing cleanly, replacement is almost always the better answer than repair. The units going into Hampshire homes today are considerably more efficient than the double glazing fitted twenty years ago, and the difference shows on a heating bill.
We survey, manufacture and fit double glazing across Fareham, Portsmouth, Gosport, Southampton and the surrounding villages, using our own installers rather than subcontracted fitters. Every installation is FENSA registered, so your certificate is issued automatically, and your building control obligations are covered without you chasing paperwork.
Choose uPVC for the keenest price and the lowest maintenance, or aluminium for slimmer sightlines and larger panes of glass. Both come in a full range of colours, handles and glazing options, and both are measured and fitted by the same team that surveys them.

Replacement Windows for Hampshire Homes
Most of the replacement windows we fit go into homes between twenty and forty years old, where the frames are sound enough to live with but the glazing has stopped doing its job. Draughts around the beading, condensation between the panes and handles that need a shove are the usual signs that the sealed units have failed.
Replacing the windows rather than repairing them lets you upgrade the whole opening at once: warmer glass, modern multi-point locking, trickle vents where building regulations now require them, and a colour that suits the house rather than whatever was available in 1998. We work room by room where budget matters, so a replacement window programme can be spread across a couple of visits instead of done in one go.
