"Daryl and your firm have been my knights in shining armour. It has been such a relief to deal withhonest, capable and interested people."


At all times James Trowse has been professional. JTQ has at all times conducted its business honestly. With respect to performance, we have noted an above-average performance and quality and a particularly high level of details. This we believe is due to the hands-on involvement of the Directs and the fact that the company has a relatively large number of its own trade employees. Martin Cooper Director Ridgemill Pty Ltd

MDI Australia

It was a pleasure to liaise with key Trowse construction personnel during all phases of the project. The management team under Simon Mountford were excellent, the project administrator was constantly on the site and always available to resolve any issues. The site foreman was a most competent and efficient site foreman. The supervision of sub-contractors was first class and the quality outcome was extremely good. The project was completed on time and on budget. Trevis McKewen, Business Manager
