Archie Scanlon Senior Contracts Administrator Strongbuild Commercial

Climax were very good during the Community Centre project – in particular undertaking design work on the fly to detail the dedicated pool PAC system that is now installed. Climax were always on site when required and the install was conducted in a tradesmen like manner. We’d have no hesitation in using climax on a similar commercial project moving forward.
