Double glazing across Tunbridge Wells
We’re Southern Window Systems, a family-run double glazing company based in Hastings since 1993. Tunbridge Wells is about 30 miles north of us, over the border in Kent, and it’s one of the areas we cover for windows, doors and conservatories.
It starts with a free home visit. We survey your property, talk through the options that suit it, and give you a clear, no-obligation quote. There’s no pressure, and if you’d like to see frames, colours and handles in person you’re welcome at our Hastings showroom.
Windows that respect a period home
Tunbridge Wells has plenty of Victorian and Edwardian houses and older period properties, alongside more modern homes. Getting the window style right matters as much as the performance, so we offer a full range:
- Vertical sliding sash windows: the traditional sliding look, with spring balances so the sashes move easily and tilt in for cleaning.
- Sash horn windows: the look of a sash, opening like a casement.
- Casement windows: simple, versatile and our most popular style.
- Tilt and turn windows: lockable ventilation, with the hardware hidden in the frame.
- Aluminium windows: slim, strong frames for a contemporary look.
Choose from a range of colours, woodgrain finishes, decorative glazing and hardware. If your home is listed or in a conservation area, check with Tunbridge Wells Borough Council before replacing windows or doors. We can help with planning and building work questions.
Warm, secure and low maintenance
Our uPVC windows are made from Liniar’s 6-chambered profile, engineered in the UK and supplied through the Double Glazing Network. All the uPVC windows we install are A-rated for energy efficiency, and the profile’s integrated reinforcement keeps them rigid and strong. They never need painting and carry a 10-year Liniar product guarantee against warping, cracking and discolouration.
For security, casement hinges are protected and every window has high-security Yale shootbolt locks as standard. We’re Yale approved installers, so the locks come with a 10-year Yale guarantee.
Front doors, bi-folds and garden doors
For a new entrance, see our page on front doors in Tunbridge Wells: composite, uPVC and aluminium. At the back of the house, bi-fold doors in uPVC or aluminium fold right back to open your room to the garden, with low threshold options and concealed locking. We also fit French doors and sliding patio doors.
Conservatories
A conservatory can give you a dining room, office or playroom full of light. We build Victorian designs with three or five facets, square Edwardian conservatories that make the most of the floor space, and lean-tos for tighter spots, all made to measure. More about our conservatories.

Do you really cover Tunbridge Wells?
Yes. Tunbridge Wells is in Kent, about 30 miles from our Hastings showroom, and it’s one of the areas we cover. We’ll arrange a free home visit and survey at a time that suits you.
Can I replace windows on a period home?
Usually, yes. Vertical sliding sash and sash horn windows keep a traditional look, and frames come in colours and woodgrain finishes. If your home is listed or in a conservation area, check with Tunbridge Wells Borough Council first. We’re happy to help with planning questions.
Are your windows energy efficient?
All the uPVC windows we install are A-rated for energy efficiency. They use Liniar’s 6-chambered profile, which traps pockets of air to keep heat in, with high-performance seals against draughts.
Will my windows be FENSA registered?
Yes. We’re FENSA registered, so your replacement windows and doors are registered and you receive a certificate showing they meet Building Regulations.
