Russel from Bubble Double Glazing has undertaken several retrofit projects at our Matiatia Bay Property with very satisfactory results. Russel can offer imaginative design solutions undertaken with utmost professionalism and care. The entire 500sqm house has been retrofitted in a number of stages which has provided an increased level of comfort both in summer and winter. The original wooden louvres in exterior walls have been replaced with colour matched aluminium louvers which has eliminated the cold drafts in winter. Overall I can not recommend Bubble Double Glazing more highly.
