Who we work with
Tier 1 contractors. Institutional developers. Asset managers who want it right.
Vector is engaged by Tier 1 contractors, institutional developers, housing associations, asset managers and architects across the UK. We are regularly called in after two or three failed investigations by others — sometimes more. The brief is almost always the same: find the leak, document it defensibly, oversee the repair.
Our monitoring work spans green roofs, landscape podium decks, inverted roofs and CLT timber structures. We work UK-wide.
