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.

I started in the trade at 17 labouring on my father on his building sites and learning from many skilled trades. I’ve worked for a few local builders since but 5 years ago went out with my father again and we have been doing so ever since. For the last 3 years we have been working mainly in north London. Have recently started taking on local work again as well due to demand for skilled and reliable trades locally.
