Groundwork & Foundations- 22 May 2026
John did a fantastic job with the groundworks for our new 150sqm block driveway. He priced keenly, started quickly and was on-site consistently every day for the week. Really skilled with the digger, good at dealing with the neighbours and always fun to talk to. Some aspects of the job changed based on what the dig uncovered, but he was pragmatic and ultimately left me feeling that he just really wanted to do a good job as if it was his own. Highly recommended - 10/10.
