What Our Clients Say

“Sage Installations replaced my tired old leaking conservatory roof with an insulated tiled roof with two glass panels, which completely transformed the space. The new roof has put an end to the extreme temperature variations in the conservatory, and the glass panels allow natural light to flood in. Now I have a bright and welcoming room which I can use all year round and it is now my favourite space in the house.”
