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.

Source FM recently helped us fit out a new 8000 sq ft warehouse in Hackney. The project included installing new electricals, installing new fire and security alarms, repairing and repainting a heavily used concrete floor, redecorating, servicing the heating etc. The project had a very tight time frame and Source FM often had to work around members of our team as we started moving in while work was still ongoing. I'm pleased to say, all the work was completed in time and to a very high standard. We've since used Paul and Bill for a number of smaller projects, both at the warehouse and in our offices.
