Latest review:
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.

Bricklaying- 9 Dec 2025
We agreed a start date for the work, and from the beginning communication was slow and required constant chasing. Alan sent me a full materials list, which I purchased on the understanding that the job was proceeding. As the start date approached, I repeatedly tried to confirm when he would arrive so I could organise my day and be available to help on site, as we agreed for me to b involved as a labour. Despite reading my messages, he stopped responding entirely. I sent multiple messages and tried calling several times over the course of a week and received no reply at all. The job never started, and I was left with purchased materials and a significant amount of wasted time. I cannot comment on the quality of his work as he never turned up, but based on the communication alone I would strongly advise others to be cautious.
