Conscientious, thorough, prompt and courteous. Ventured unbidden into a no-go area of the loft space.

Brilliant and easy and good value.

I would recommend Steve Johnson to do all structural calculations. He was brilliant. I told him what my needs were and he let me know what was suitable. Giving me all the calculations and how to get a certificate from the council when the work is done. I have every confidence in steves ability and knowing my house is going to ok is very important to me.

Highly recommended

Steve was very professional and prompt in dealing with our request. I do not know anything about buildings and the prospect of employing a structural engineer was a bit daunting. After speaking to Steve I felt reassured that I am dealing with someone who knows what they do and who is trustworthy. His expert advice helped us save a lot of money and hassle for a house purchase.
