I've recently had 2 steel joists put in for me and both were cleared by the council inspector without hesitation - great job, honest advice and reasonable price too. His name is David O'Doherty - 07830119421, I know he is on holiday at the moment so I'd give him a week or so.
Dave worked to structural engineers drawings, I got a few quotes for this work and the guy I used was about half the price of others! If you'd like his details send a connection request I'll forward his details also.
Could I have the contact details for both the builders and structural engineer (no urgency, no need at the moment, but handy to have a good one). Sent you a DM.
I can also whole-heartedly recommend Radek. Very friendly, quick, efficient and great crew.
Very helpful at all stages, will be using him again as soon as I can free up some budget for the bathroom!
Yeah, his name is Philip Graham and can be contacted on 020 88830612, he lives in Muswell Hill. Graham is 'old school', hence no mobile, and you won't get CAD drawings but traditional pen drawings - I have to say when I received mine I was well pleased - a long forgotten 'art' you could almost frame them! To top it off Graham was cheaper, by far, than any other quote I received.
Good luck and I hope your project goes well.
