If you’re looking to upgrade your existing conservatory then you’ve come to the right place, we can transform your old conservatory into a liveable space once again, keeping you warmer in the winter and cooler in the summer.

As younger generations come forward to continue the success of our established business, the future looks bright for Alexander, and we’re keen to translate our family values to installations across Sussex and beyond.

Our customers really see the difference once they have had a Garden room Roof installed.  No longer is their conservatory too hot in Summer and too cold in Winter. They can use their conservatory all year round.  It really does make such a difference. The whole roof is totally replaced with a brand new tailor made to your requirements with multi layers of insulation. The inside is a plastered finish and most of our customers paint the ceiling white as this colour reflects the light. Some customers choose Velux roof window options.
