We went to Hydromedial to find the source of the water ingress in our home. We then engaged them to project manage the resulting works to fix the issues. At all stages, they were communicative, thorough and clear. They presented multiple solutions to our problems - allowing us to weigh up what worked best withi
I would thoroughly recommend Hydromedial Consulting Group for any project you may be considering. Their professionalism, technical expertise and commitment to achieving strong client outcomes are of the highest standard. As a member of the Strata Committee of a residential strata complex in Manly, I worked closely with Hydromedial Consulting Group over several years on two major projects for our Owners Corporation. The first involved significant remedial works to the building, where project managers Karl van Hoogenvest and Mark Bradbury provided comprehensive project management services. This included liaising with our solicitors, coordinating builders, overseeing all aspects of the works and maintaining clear and consistent communication with the Committee, resulting in a successful outcome. The second project related to a Fire Upgrade Order issued by Northern Beaches Council. Once again, Karl and Mark demonstrated exceptional professionalism and technical knowledge by engaging the appropriate consultants and developing several compliant alternative solutions. Their strategic and practical approach significantly reduced the overall cost burden on owners while maintaining safety and regulatory requirements. Across both projects, Hydromedial Consulting Group consistently demonstrated strong risk management, detailed knowledge of construction methods and fire and electrical design, excellent communication and documentation practices, and a clear ability to explain complex issues in practical terms. Their experience in contract management, combined with their dedication to quality and delivery, was evident throughout. I have no hesitation in recommending Hydromedial Consulting Group to any owners corporation or client seeking a highly capable and professional consultancy.
