Extensions- 10 Sep 2019
Do not hesitate to use these guys. Nothing is too much for them. Rob and his team built my kitchen extension and I am over the moon with the work. Rob is a perfectionist and from day 1 was personable, professional and 100% trustworthy. The plumber, electrician, bricklayer, tiler and carpenter that were used were top class. They all made the whole process so easy. I would wholeheartedly recommend this company and their team. If you would like to come and have a nose, just let the company know and I am happy to show you their work. Any changes that we made along the way were taken on board and everything is perfect and exactly as we wanted. The guys never cut corners. Thank you for our beautiful extension. It has changed the way we live for the better.

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.
