Extensions- 22 Dec 2025
We contracted JMD for a detached house project to demolish an old 1970s extension & rebuild larger 70sqm extension, an outside terrace patio and remodel some of our internal ground floor setup. Project started in Feb2025 and JMD made super quick progress on the build during the dry spring months. We had to pause JMD due to our timelines which they were fine with and finally completed end-to-end by Oct2025. What makes JMD standout for us was their team of employees – they don’t use too many contractors, most of their team are employed by JMD and are a loyal hardworking professional squad. Liam, Mark, Chip, Ross, Zac and the rest – all top class! We had some additional projects and requirements mid-project, JMD provided good pricing along the way which were all totally fair and priced as incremental add-ons. YES – there are always bits that could be better, but JMD did an excellent job on the whole. Site left clean, tidy, complete and all post project snags dealt with! THANKS JMD!

Fencing- 13 Mar 2026
We hired Bawa to install new fencing, and he did a fantastic job from start to finish. You can immediately tell he’s an all-rounder who understands construction very well. The work was carried out efficiently and to a high standard. Bawa has a great attitude, is very hard-working, and clearly takes pride in what he does. Communication was easy throughout, and the whole process felt smooth and professional. It was a real pleasure having Bawa work for us, and I wouldn’t hesitate to recommend him.
