We always aim to provide clear, honest communication and solutions, hitting crucial deadlines and managing the technical details that are imperative in every project, from small-scale commercial work to large-scale projects such as schools, offices, hospitals and accommodation.

Working with the highly-respected Profile22, we have developed a substantial track record of assisting contractors, specifiers, architects, the NHS, housing associations and more. The vibrancy of this portfolio, combined with our dedication to quality uPVC products and prior experience, means we’re always able to perform at a high-standard.

We have worked with and continue to work many commercially focused companies including RGB Group, Reirse Ryan, Colmore Tang, Castlemead Group, Box Construction, Takare, HOC Construction, Longcross Construction, BUPA, Persimmon Homes and more.
