Our Trusted Partners

We engaged CWL for the geothermal and HVAC works on our unique project in Bellevue Hill and were selected based on pricing and their previous experience. It turned out to be the best choice in subcontractors we made for the whole project. Their professionalism, work ethic, expertise and willing to help wherever needed made a highly complex services installation that much easier, and more efficient than expected. I’d like to personally thank James and the site team who put the extra effort in at all times to get our project over the line with remarkable results. Highly recommended Subcontractors and mechanical consultants.
- Theo Elphick, Site Manager, Built
A culture of striving for excellence combined with motivated and dedicated staff is what defines CWL Group. Their workmanship is second to none and it is obvious that all of the staff care about what they do. Commitments are met and exceeded and there are no problems that can’t be resolved. I’m looking forward to working with Clayton and his team in the future and have no hesitation in recommending them to anyone.
- Mick Carroll, Bellevarde Constructions
The team from CWL Group are very reliable, responsive and efficient in their work. They go above and beyond to make sure the job is completed at its highest standard. The knowledge of the guys is exceptional. I would recommend the CWL Group team every time!
- Annemarie Rodrigo, Bellevue Hill House Keeper
I want to thank CWL Group for the outstanding work in installing our hydronic heating system. I have worked with many plumbers over the years and I have never seen such a high standard of workmanship. They came in on time and on budget. I cannot recommend the team from CWL Group highly enough.
