Carpentry- 25 Feb 2021
Hiring Kyle for our project was the best decision we made. We had undertaken a self build and Kyle acted as both our site foreman and an experienced chippie. He helped us build a unique house even though there were a lot of logistical challenges.I would not hesitate recommending Kyle to anyone he's an extremely diligent and professional carpenter who has great attention to detail.

Hard Flooring- 22 Oct 2025
Enea did an incredible job, and we’re beyond happy with the final result. He was very accommodating, helped us choose the right tone of varnish beforehand, and kept us updated throughout the day by sending pictures of his progress (as we were both at work). Enea is trustworthy, and even though we didn’t have the chance to meet him in person, he left the flat securely, taking care of our keys and door. We highly recommend Enea!
