Windows

Our UPVC windows are designed for energy efficiency and security, featuring A-rated glass and multi-point locking systems. Available in a range of styles and colours, they enhance thermal performance while reducing noise pollution. Perfect for both modern and traditional homes, these windows offer durability and low maintenance.

Doors

Composite doors combine aesthetic appeal with robust security, featuring reinforced frames and high-performance locking systems. Available in various finishes, they provide weather resistance and insulation, ideal for improving home security and energy efficiency. Each door is custom-made to suit individual property styles.

We design and install conservatories that create additional living space with maximum natural light. Options include Edwardian, Victorian, and lean-to styles, all built to withstand seasonal changes. Upgrades like insulated roofs ensure year-round usability, transforming your home into a versatile living area.

An excellent company. Great quality windows and doors and a friendly and professional service. We have used this company three times now for different projects and they never dissapoint. We had our car broken into and keys stolen, they made it a priority to change our locks for us, you don't get that very often these days, I was quite overwhelmed with how serious they took it. If you want a company that cares about you as well as the job then use Celestial.

Great service from start to finish. We looked at a few companies before picking Celestial to install our new conservatory and they delivered a great product for us at a good value. Everything went smoothly from initial conversation through to design and installation. I would highly recommend them based on our experience.
