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.
