All our conservatories are constructed by our dedicated teams of ground workers and window installers. From quotation through to survey and final fit we keep our customers fully informed. At Super Seal we offer a full fitting service, including electrics and Air Conditioning if required. We are unique in that the Roof will match the windows of the conservatory exactly – not bought in from different sources as most companies do.

There are many types of glazing materials used in the roofing of our conservatories, different thicknesses of Polycarbonate, different colours and many types of glass, including Low Emissivity, Laminated and Self Cleaning Insulated Glass. Whatever you wish to use your conservatory for, Super Seal will give you “best advice” and the benefit of their vast experience.
