Conservatory Installations in Chichester & West Sussex

Conservatories Designed, Installed and Repaired in Chichester
Keystone Glazing designs and installs complete new conservatories across Chichester and West Sussex. We also upgrade existing conservatories with replacement glazing, new frames, glass roofs and insulated warm-roof systems, helping homeowners create comfortable living spaces they can use throughout the year.
We are a local, family-run company with more than 25 years’ experience, and every conservatory is surveyed, made to measure and fitted by our own team. Whether you want a new garden room, a warmer roof on the conservatory you already have, or a repair to misted glass, sticking doors or tired seals, we will give you honest advice and a free, no-obligation quote.
Why Choose a Conservatory?
- Extra living space – perfect for entertaining, relaxing or working from home, without the cost and disruption of a full extension.
- Year-round comfort – A-rated glass and an insulated roof keep the room usable in summer and winter.
- More daylight – glazed walls and roofs bring light deep into the house and open it up to the garden.
- Security – multi-point locking and toughened safety glass come as standard.
- Adds value – a well-built conservatory makes a home more appealing to buyers.
Conservatory Styles We Install
Every conservatory we build is designed around your home, your garden and how you plan to use the room. The main styles are:
Victorian conservatories
A faceted bay front and a steep, ornate roof give a traditional look that suits period and Edwardian-era houses across Chichester and the surrounding villages.
Edwardian conservatories
A square or rectangular plan makes the most of the floor area, so the room is easy to furnish as a dining room, snug or home office.
Lean-to conservatories
A simple mono-pitch roof that sits neatly under bungalow eaves or first-floor windows. A lean-to is often the most cost-effective option and works well on smaller plots and coastal homes in Selsey, Felpham and Pagham.
Gable-end conservatories
An upright, fully glazed front and a high-pitched roof create a bright, spacious room with plenty of headroom.
P-shape, T-shape and orangery-style rooms
Combined styles wrap around corners or add a separate dining area. Orangery-style rooms pair solid brick piers with a roof lantern, sitting between a conservatory and a roof lantern extension.
Frames, Glass and Doors
We fit trusted, British-made systems from manufacturers we have worked with for years:
- REHAU uPVC – slim, strong and low-maintenance, in white, cream, grey, black and woodgrain finishes.
- SMART aluminium – narrow sightlines and large glass areas, ideal for contemporary rooms and bifold doors.
- Residence Collection – the look of traditional timber flush-sash joinery with the low maintenance of a modern frame.
All conservatories are double glazed with A-rated, toughened safety glass and warm-edge spacer bars, and triple glazing is available where you need even better insulation or noise reduction. Access can be through French doors, sliding patio doors or aluminium bifolds – you can design your bifold doors online before we visit. Other products are available on request.
Conservatory Roofs and Warm Roof Upgrades
The roof makes the biggest difference to how comfortable a conservatory feels. Many older conservatories have thin polycarbonate or early glass roofs that make the room too hot in summer and too cold in winter. We offer:
- Energy-efficient glass roofs – modern solar-control glazing that keeps the room bright while cutting glare and heat.
- Insulated tiled and warm roof systems – a solid, plastered ceiling inside, so the room can be used all year.
- Roof windows and lanterns – extra daylight and ventilation in a solid or flat roof.

- Renewing worn seals and gaskets to stop draughts and leaks
